Privacy Policy for My GCT Hub

Effective Date: August 16, 2026
Last Updated: August 16, 2026

Developer: Ragavan M (independent student developer)
App Name: My GCT Hub
Contact Email: ragavan.devp@gmail.com
Policy URL: https://mygct.org/app/privacypolicy

Important Disclaimers — Please Read First

1. This is NOT an official college application

My GCT Hub is NOT an official app of the Government College of Technology (GCT), Coimbatore. It is NOT affiliated with, endorsed by, sponsored by, approved by, or managed by GCT, its administration, its faculty, or any government body. The app is built and maintained independently by an individual student developer as a personal, non-commercial learning project. The name "GCT" is used only to describe the student community the app is intended for, and no claim of official status, authority, or representation is made. Any information in this app must not be treated as an official college announcement. For official information, always refer to the college's own official channels.

2. All post content is uploaded by students — not by us

Every post, PDF, note, question paper, syllabus copy, reference book, image, title, comment and description inside My GCT Hub is created and uploaded by individual student users themselves. This content does NOT belong to My GCT Hub, is NOT written, authored, verified, endorsed or owned by My GCT Hub or its developer, and does NOT represent the views of My GCT Hub, its developer, or GCT. The app only provides a neutral hosting and sharing space. Each uploading user is solely and fully responsible for the content they upload and for having the legal right to share it.

3. Copyright and privacy of uploaded material

Users are strictly prohibited from uploading copyrighted books, paid study material, pirated PDFs, or any file containing another person's private or personal information without their consent. Because uploads come from users, it is possible that a user may upload material that infringes a copyright or discloses someone's private data without our knowledge and against our rules. We do not authorise such uploads. When we are notified of such content, we remove it — see Section 12: Reporting Content, Copyright and Takedown Requests. Rights holders and affected individuals may request removal at any time by emailing ragavan.devp@gmail.com, and we act on valid requests as quickly as possible (normally within 48 hours).

4. Placement information is posted by students, and is not official

The Companies section is written entirely by student users — company names, logos, eligibility figures, salary figures, job descriptions, the selection rounds, the preparation links and the feedback underneath them. None of it comes from the college, from the placement cell, or from the companies themselves, and none of it is verified by us. A company's logo and name are shown only to identify which firm a student is describing; their appearance in the app does not mean that company is associated with, sponsors, endorses or has approved My GCT Hub in any way, and no partnership of any kind is claimed or implied. Never treat an eligibility cut-off, a package figure, or a drive date in this app as official. Always confirm with the college placement cell before acting on it. Feedback about an interview is one student's personal opinion of their own experience, not a statement of fact about that company. The preparation links under a company are typed in by a student and open in your own browser, outside the app. We do not control, check or endorse what is on the other end of them, and once you tap one you are on that website and its privacy policy applies, not ours. If you are a company representative and something here is wrong or should not be published, email us and we will correct or remove it — see Section 12.

What changed in this update — 16 August 2026

New features have been added since the last version of this policy. These are the ones that affect your data, spelled out here rather than left to be found in the sections below:

There is a new Companies section, and anything you write in it is public. Any approved account can post feedback about a company's interview, and it is shown to every other user with your name and profile picture beside it. You can edit or delete your own feedback at any time, and nobody else can — but anyone who read it before you changed it has already read it. See Section 2.7.
A new account role, Placement Rep. An administrator can appoint a student as a placement representative, which lets them add and edit companies. Their name, picture and role are shown publicly on every company they add or edit. See Section 2.3.
Three new tools that keep their data only on your phone. A to-do list with reminders, a money tracker for what you spend and receive, and a timetable you upload a picture of once. None of these three send anything to us — not the tasks, not the amounts, not the picture. They stay on your device and are deleted when you uninstall the app. See Section 2.11.
Your timetable and company logos are picked with Android's own picker. The app still requests no gallery or photo permission at all and still cannot browse your photos — the system picker hands over only the single image you tap. See Section 3.
Deleting your account now also deletes your placement feedback and any reports you filed, and takes your name off any company you added. See Section 10.

1. Introduction

This Privacy Policy explains what information My GCT Hub ("the app", "we", "us") collects from you, why each piece of information is needed, how it is used and stored, who it is shared with, and how you can review or delete it. It also explains, permission by permission, why each Android permission the app requests is required.

By creating an account and using the app, you agree to this policy. If you do not agree, please do not use the app. You can delete your account and all associated data at any time (see Section 10).

2. Information We Collect and Exactly Why

2.1 Account information (collected via Google Sign-In)

The app has no password of its own. Signing in is done through Google Sign-In, so we never see, receive, or store your Google password. From your Google account we receive only:

Data	Why it is needed
Email address	It is the unique key that identifies your account, lets you sign in again on a new device, and lets us contact you about your account or a report concerning your content.
Name	Shown as the author name on posts and comments you create, so other students know who shared a file and can judge whether to trust it.
Profile picture URL	Displayed next to your posts and comments. This is a link to the picture hosted by Google; we do not copy the image to our servers.

We do not request or receive your Google contacts, Gmail messages, Google Drive files, calendar, or any other Google data.

2.2 Academic profile details you type in

Department, batch/year, semester and regulation. Why: the app's entire purpose is to show you only the study material that matches your course. Without these, every user would see all material from every department and the app would be unusable. These are chosen by you and can be changed in the app at any time.

2.3 Your account role (who is allowed to post)

Every account carries a role: Unauthorized, Student, Staff, PlacementRep or Admin. Every new account starts as Unauthorized, which means you can sign in, read, search, download, comment and use the calculator, but you cannot upload anything until an administrator approves your account and changes your role.

PlacementRep is a new role added in the August 16, 2026 update. It is given by an administrator to the student who looks after placement information, and it is the only role besides Admin that may add or edit companies in the Companies section. It is not something you can request or grant yourself, and it gives no access whatsoever to other users' accounts, calculator data, or anything stored on their phones. If you hold this role, the companies you add carry your name, picture and role publicly — see Section 2.7.

Why: uploads are the one action that puts a file in front of the whole college, so the ability to publish is granted deliberately rather than automatically. It is the app's main defence against spam, pirated books and material uploaded by people with no connection to the college.

The role is stored on your account record and is shown publicly as a badge on the posts you create, so other students can see whether a file came from a student or a staff member. To review an approval request, an administrator can see your name, email address, profile picture, role, credit balance, lifetime earnings, how many items you have posted, and the date you joined. Administrators cannot see your password (nobody can — see 2.1), your calculator data, or anything stored only on your phone.

2.4 Content you choose to upload (user-generated content)

PDFs, notes, question papers, syllabus files, reference book entries (title, author, edition), scanned pages, and comments. Cover images are not uploaded by you — they are generated automatically on our server from the first page of the PDF. Why: this is the material other students read — it is the app's core function. This content is public to other signed-in users of the app and is stored together with your user ID so it can be attributed to you, so you can delete it later, and so it can be removed if it is reported. Do not upload anything private, confidential, copyrighted, or belonging to another person.

2.5 Activity and interaction data

Data	Why it is needed
Views (one record per post per user)	To show an accurate view count and to make sure a post's view is counted only once per user. It also credits the uploader fairly (see 2.6).
Likes / "relevant" and "not relevant" marks	To rank useful material higher and to let you undo your own like. Stored against your user ID so the app knows which posts you have already marked.
Comments	To let students discuss material and flag mistakes in it. Stored with your user ID so you can delete your own comment.
Downloads and favourites	Download counts help other students see which files are useful; favourites let you re-open a file you saved.
Reports you submit	If you report a post, we store which post it was, the reason you chose, any details you typed, and your user ID. Why: a report has to be traceable for a moderator to act on it and to stop the same post being reported repeatedly by one account. Reports are never public and the uploader is not told who reported them. See Section 12.

2.6 Credit points

Uploaders earn credit points when their material is viewed by others. We store your points total and lifetime earnings. Why: to reward students who contribute useful notes. Redeeming points is completely optional. If you choose to redeem, the app opens WhatsApp with a pre-filled message containing your name, email, user ID, point total and the UPI ID you type in, addressed to the developer. We do not store your UPI ID on our servers, and the app never asks for your bank account, card details, or any other financial information. Once you send that message, WhatsApp's own privacy policy applies to it.

2.7 The Companies section (placement board and feedback)

This is new in the August 16, 2026 update. The Companies section lists firms that visit the college, and lets students share what an interview was actually like. Everything in it is written by students — see disclaimer 4 at the top of this policy. There are two separate things happening here, and they collect different data.

(a) The company entries — written only by Placement Reps and Admins

An account with the PlacementRep or Admin role can add a company and fill in its name, logo image, website link, required CGPA, salary in LPA, expected domain knowledge, job description, the departments allowed to attend, the month and year the company last visited, the selection rounds it runs, and any preparation links — each being a title and a web address. The logo image is uploaded to and stored on our servers, unlike PDF covers which are generated automatically. None of these fields is personal data about a student — they describe a company, and they must never be used to record anything about an individual.

The preparation links point outside the app. They are typed in by a Placement Rep and are not checked by us. Tapping one opens your own browser and leaves My GCT Hub; from that moment you are on somebody else's website, under their privacy policy, and anything you do or enter there is between you and them. We do not send your name, your account or any other data from the app to those sites. If a link here leads somewhere it should not, report it — see Section 12 — and we will remove it.

Any Placement Rep or Admin can edit any company, including one somebody else added. Because of that, each company shows who created it and who last edited it — name, profile picture, role and date, visible to every user. This is deliberate: figures that decide whether a student sits for a drive should be traceable to the person who typed them, so that they can be questioned and corrected. If you accept the Placement Rep role, you are accepting that your name and picture appear publicly on every company you touch.

(b) The feedback — which any approved account can write

Under each company, any account an administrator has approved can post feedback describing their own interview experience. We store the text you write, your user ID, and the date, and the screen shows your name and profile picture beside it to every other user.

Please read this before you post feedback.

It is public. Every signed-in user of the app sees it, together with your name and your profile picture. It is not anonymous.
You can edit it or delete it at any time, from the same screen — the Edit and Delete buttons appear on your own entries. Deleting removes it from our servers completely. You can also post more than one entry about the same company; a second interview a year later is a second experience.
Only you can. No other student, no placement representative and no administrator can edit or delete what you wrote — the app checks on our servers that an edit or a deletion comes from the person who wrote the entry, not merely from someone who says it did. An edited entry is marked edited so other students can see it was revised.
Editing is not un-publishing. Anyone who opened the screen before you changed or deleted it has already read the original, and may have screenshotted or copied it. We can remove it from the app; we cannot take it back out of somebody's memory or gallery. Please write it as though it is permanent, because in that sense it is.
It also goes when your account does. Deleting your account erases every piece of feedback you have written (see Section 10). You can additionally email ragavan.devp@gmail.com if you cannot reach the app.
Write about your own experience of the process, not about people. Do not name individual interviewers, do not post anything you were told in confidence or signed an NDA about, and do not include anyone else's personal details. Feedback that breaks these rules is removed and the account may be suspended.

Why we keep it at all: a student deciding whether to prepare for a drive is best served by what the last batch actually experienced. Attaching a real name to it is what stops it becoming anonymous rumour about a named company, and being able to correct or withdraw your own account of an interview is what stops a mistake made in five minutes following you around for four years.

Reading the section requires no role at all and collects nothing beyond the ordinary request our servers receive for any screen.

2.8 GPA / CGPA calculator data (saved automatically)

This changed in the August 2026 update. There is now a single GPA & CGPA calculator, and it no longer asks whether to save or where. There is no save button and no "save on this phone" option — the phone-storage option has been removed entirely. Instead, what is on the screen is written to your My GCT Cloud automatically, about a second after each change, and read back when you open the calculator again.

What is stored, for each subject you add:

Data	Why it is needed
Semester number (1–8)	To group your subjects and work out a separate GPA for each semester.
Subject name	So the list means something when you come back to it — and so you can tell which paper an arrear belongs to. The subject name is now required, where it used to be optional. It is a subject title such as "Engineering Mathematics", not personal information.
Credit and grade point	The two numbers the formula multiplies. Your letter grade (O, A+, A, B+, B, C, RA) is stored as its point value (10, 9, 8, 7, 6, 5, 0).
The calculated GPA / CGPA and total credits	Recalculated on our server from the rows above, so a stored result can never disagree with the subjects stored beside it.

Why it is saved at all: this is a record built up one subject at a time across four years of a degree. Keeping it on your account means it survives a lost, reset or replaced phone, and is there when you sign in on a new one.

It is one record, not many. Each change overwrites the same single record on your account — the app does not keep a history of previous versions, and there is no list of past saves.

Your control over it:

Tapping "Clear" in the calculator deletes the record from our servers immediately, not just from your screen. Emptying the calculator is how you delete this data, and it cannot be undone.
If you are not signed in, or you are offline, the calculator still works normally — it simply does not save, and the screen tells you so.
The record is automatically and permanently deleted four years after it was first created — the length of the degree these marks belong to. Continuing to edit it does not extend that four-year clock.
Deleting your account deletes it straight away (see Section 10).

Nobody else can see this data. It is not public, it is never shown to other students, and it is not visible to administrators.

2.9 The PDF report you can share

The calculator has a Share button that builds a PDF report and passes it to Android's share sheet, where you choose which app or person receives it. This happens only when you press that button.

The PDF contains: your name and email address as they appear on your account, the date and time it was generated, every subject you entered with its credit and grade, each semester's GPA, your overall CGPA, and a count of any papers still marked RA.

Please note: because the report carries your name and email address, sending it to someone discloses those details to them. We do not send this file anywhere ourselves and we never see it — it is created on your phone and handed to the app you pick. Once you have sent it, it is out of our control and out of yours, exactly like any other file you send.

The generated PDF is written to the app's own temporary cache folder on your device so that the share sheet can read it. The previous report is deleted each time you generate a new one, it is removed when you clear the app's storage or uninstall the app, and it is never uploaded to our servers.

2.10 Device notification token

A Firebase Cloud Messaging (FCM) token — an anonymous device identifier generated by Google, not a hardware ID. Why: it is the only way to deliver a push notification to your specific device. It is stored linked to your account so notifications reach the right person, and it is deleted when you delete your account.

2.11 Data stored only on your phone (never sent to us)

Your favourites, your chosen department, regulation and semester, your login session, cached lists, any files you downloaded and the last PDF report you generated are stored locally on your device. This data never reaches our servers and is removed when you uninstall the app or clear its storage.

Three tools added in the August 16, 2026 update work entirely this way. They have no account, no sync, no backup and no server side at all — the app sends us nothing from any of them, and we cannot see any of it:

Tool	What it keeps on your phone	What reaches our servers
To-Do list	The tasks you type, the date and time each is due, whether you asked for a reminder, and whether it is done. Reminders are scheduled by your own phone, not sent by us — so they arrive even with no internet, and the text of your tasks never leaves the device.	Nothing.
Money tracker	Each amount you enter, whether it was money spent or received, the category you picked, an optional note, and the date. This is financial information, which is exactly why it is kept on your phone alone and never uploaded.	Nothing. We never see your amounts, your balance, or your notes.
Timetable	One image you choose — a photo or screenshot of your class timetable. The app copies that single picture into its own private storage so it opens instantly without going back to the gallery. Removing it in the app deletes the copy.	Nothing. The picture is never uploaded, never backed up by us, and we never see it.

Because these three live only on your phone, they are not restored when you sign in on a new device, and they are gone if you uninstall the app or clear its storage. They are also not affected by deleting your account, for the simple reason that we never had them.

Note: your GPA/CGPA calculator entries are no longer among the data stored locally. Until the August 2026 update the app could store calculator results on your phone; that option has been removed, and this data now lives only on your account (see 2.8).

2.12 What we never collect

Passwords of any kind (login is handled entirely by Google).
Bank account numbers, card details, or payment credentials.
Your contact list, call logs, SMS messages, or phone number.
Precise or approximate location / GPS data. The app requests no location permission at all.
Health data, biometric data, caste, religion, or any other sensitive personal category.
Background audio, background camera capture, or screen recording.
A list of other apps installed on your device.

3. Android Permissions — What Each One Is For

Below is every permission declared by the app and the exact feature it enables. Permissions marked "asked when used" are requested only at the moment you tap the feature, and the rest of the app continues to work normally if you deny them.

Permission	When it is requested	Why it is needed / what happens if you deny it
`INTERNET`	Automatic (no prompt)	The app must connect to our servers to load subjects, posts, PDFs and the placement board, and to upload the material you share — without it, none of the shared features work. The tools that keep their data on your phone — the to-do list, money tracker, timetable, calculator and games — keep working with no connection at all. Internet access is never used for advertising or tracking.
`POST_NOTIFICATIONS`	Asked when used — on first launch, and only once	Two different kinds of notification use this one permission. (1) Alerts we send about new study material for your department, replies on your posts, and important academic updates. (2) Reminders for your own to-do tasks, which are scheduled and delivered by your phone itself — the task text never leaves your device and we are not involved in delivering them. Task reminders have their own notification channel, so you can silence them in Android settings without silencing the rest. Deny the permission and everything else still works — you simply will not get alerts. We do not send marketing or advertising notifications.
`CAMERA`	Asked when used — only when you open the in-app document scanner	To let you photograph handwritten notes or a printed page and turn them into a PDF you can upload. The camera is used only while the scanner screen is open and only after you press the shutter. There is no background, hidden, or automatic camera use, and the app never opens the camera on its own.
`RECORD_AUDIO`	Asked when used — only when you tap the microphone icon in a search box	To power voice search, so you can speak a subject or book name instead of typing it. Recording starts only on that tap and stops as soon as the phrase is recognised. The speech is converted to text by your device's own Android speech recogniser; we never record, upload, or store any audio, and no audio ever reaches our servers. Deny it and you can still search by typing.
No photo, gallery or media permission (Android 13 and newer)	Never asked	On Android 13+ the app requests no storage, photo or media permission whatsoever — not `READ_MEDIA_IMAGES`, not any other. Every file the app picks goes through Android's own system picker, which hands back only the single item you tapped: a PDF to upload, the image of your timetable, or a company logo if you are a Placement Rep. The app therefore has no ability to read, browse, scan or index your gallery, photos or documents, and cannot see any picture you did not personally select.
`READ_EXTERNAL_STORAGE` (Android 12 and below only)	Asked when used — only when you pick a PDF, a timetable picture or a company logo	On Android 12 and earlier this is the only way the system file picker can pass the file you chose to the app. It is declared with `maxSdkVersion="32"`, so it is never requested on Android 13 or newer. Only the one file you select is read; no other document or photo is accessed.
`WRITE_EXTERNAL_STORAGE` (Android 10 and below only)	Asked when used	To save a PDF you download, or a PDF the scanner generates, into your device's Downloads folder so you can open it offline in any PDF reader. It is declared with `maxSdkVersion="29"`, so it is never requested on Android 11 or newer, where the app writes only to its own private folder.
`VIBRATE`	Automatic (no prompt, not a privacy permission)	Short haptic feedback when an action fails or completes (for example, an invalid input). It gives access to no data whatsoever.
PDF viewer & speech-service `<queries>`	Automatic (no prompt)	On Android 11+, an app must declare which app types it needs to interact with. We declare only two: apps that can open a PDF (so "Open with" works after a download) and the system speech-recognition service (so voice search can detect that it is available). This does not let us see the list of apps installed on your device.

4. App Features and the Data Each One Uses

Feature	What it does	Data involved
Study material feed	Shows semester question papers, unit tests, syllabus and notes for your department and semester.	Your department/semester/regulation choices; view records.
Reference books section	Book entries uploaded by students, with title, author and edition. The cover shown is generated automatically from the PDF's first page.	Uploaded by users. Content responsibility lies with the uploader — see the disclaimer above and Section 12.
Upload / New Post	Lets you share a PDF or scanned notes with your department. Available only once an administrator has approved your account (see 2.3).	The file itself, your user ID, and the subject/department it is filed under.
Document scanner	Uses the camera to photograph pages and build a watermarked PDF.	Camera permission; the images stay on your device until you choose to upload.
Upload from PC	Generates a temporary web link so you can upload a PDF from a laptop browser instead of your phone.	A random one-time token plus your user ID, subject and department. The link expires and is permanently deleted after 20 minutes.
Present mode	Generates a 4-digit code to open a PDF on a classroom projector screen.	The code and the PDF link only. Deleted automatically after 5 minutes. No personal data is attached to the code.
Search (typed or voice)	Finds subjects, books and materials by name.	The search text. Voice input is converted to text on your device; no audio is stored or transmitted to us.
Likes, comments, favourites	Lets you mark material as useful, discuss it, and save it for later.	Your user ID linked to the post; comment text.
Report a post	Flags copyrighted, private, offensive or misleading material for review and removal.	The post reported, the reason, optional details, and your user ID (see Section 12).
GPA & CGPA calculator	One calculator for both: you add each subject with its semester, name, credit and grade, and it shows a GPA per semester and your overall CGPA as you type.	Semester, subject name, credit and grade point — saved to your account automatically, with no save button and nothing kept on your phone. Auto-deleted after 4 years; "Clear" deletes it at once (see 2.8).
Share results as PDF	Builds a report of every subject, each semester's GPA and your CGPA, and passes it to Android's share sheet.	Your name, email and the date/time are printed on the report. Created on your phone; we never receive it. You choose the recipient (see 2.9).
Credit points & redeem	Rewards uploaders whose material is read by others.	Point totals. Redeeming is optional and goes through WhatsApp; no financial details are stored by us (see 2.6).
Companies (placement board)	A list of firms visiting the college with their eligibility CGPA, package, domain, job description, departments allowed, last visit month/year, the selection rounds and links to preparation material. Only Placement Reps and Admins can add or edit one; any of them can edit any company (see 2.7).	The company details and its uploaded logo image. The name, picture and role of whoever created it and whoever last edited it are shown publicly on the company. Preparation links open in your browser, outside the app, and the site you land on is not ours (see 2.7).
Company feedback	Lets an approved account describe their own interview experience under a company.	Your text, your user ID and the date; your name and picture are shown publicly beside it. You can edit or delete your own entries at any time, and only you can (see 2.7).
To-Do list & reminders	A personal task list with a due date and optional reminders, including one daily summary.	None reaches us. Tasks stay on your phone and reminders are scheduled by the phone itself (see 2.11).
Money tracker	A private log of what you spend and receive, by category and month.	None reaches us. Amounts, categories and notes never leave your device (see 2.11).
Timetable	You upload one picture of your class timetable and it opens instantly, offline, with pinch to zoom — instead of hunting through the gallery several times a day.	None reaches us. The image is copied into the app's own private storage on your phone and is never uploaded (see 2.11).
Chess and N-Queens games	Offline single-player puzzles included as a study break.	None. They run entirely on your device and collect nothing.
Push notifications	Alerts about new material and updates for your department.	Your FCM device token (see 2.10).
Shared links (deep links)	Opening a `mygct.org` post link opens it directly in the app.	Only the link path. No extra data is collected.

5. How We Use Your Information

To create and operate your account and show material relevant to your department and semester.
To display your name and picture as the author of content you post.
To deliver notifications you have opted into.
To count views, likes and downloads, and to award credit points fairly.
To decide whether your account is approved to publish, and to show your role as a badge on your posts.
To keep your calculator entries in step across your devices.
To show the placement board, and to show who added or last edited each company so that the figures on it can be traced and questioned.
To display feedback you write about a company, under your name, to other students.
To respond to your support, deletion, report or takedown requests.
To detect and remove content that violates our rules or the law.
To fix crashes and improve app performance.

We do not sell, rent, trade, or share your personal data with data brokers, advertisers, or any third party for marketing purposes. The app contains no advertising SDK and no third-party advertising or behavioural tracking.

6. Data Sharing and Third-Party Services

Your information is shared only in these limited situations:

Publicly inside the app: your name, profile picture and anything you post or comment are visible to other signed-in users. This is unavoidable for a sharing app — please treat everything you upload as public. This includes any feedback you write about a company, and — if you hold the Placement Rep role — your name and picture on every company you add or edit (see 2.7).
Google Sign-In (Google LLC) — verifies your identity at login. Governed by Google's Privacy Policy.
Firebase Cloud Messaging (Google LLC) — delivers push notifications; it processes your device token and the notification text only. Governed by Google's Privacy Policy.
Hosting infrastructure — our own servers and database, which store the data described above solely to run the app.
With whoever you send a report to: if you use the calculator's Share button, the PDF you send carries your name and email address. You choose the recipient and the app it goes through; we are not involved in that transfer and never receive the file (see 2.9).
With the app's administrator: to approve accounts for posting and to moderate reported content, an administrator can see the account details listed in Section 2.3. They cannot see your calculator data.
When required by law — if we receive a valid legal request from a competent authority, or where disclosure is necessary to investigate a copyright or privacy complaint.

Links out of the app share nothing. A company's website and the preparation links under it open in your browser. We send that site no data of any kind — not your name, not your account, not the fact that you came from here. Those sites are not ours and are not checked by us; once you are on one, its own privacy policy governs what it collects (see 2.7).

We do not use Google Analytics, advertising networks, or any behavioural profiling service.

7. Data Storage, Security and Retention

Data is stored on our backend servers and database, accessible only to the developer.
Communication between the app and our servers uses HTTPS encryption, and every API request must carry a private application key.
We hold no passwords, because authentication is delegated entirely to Google.
Account data is retained for as long as your account exists, and is erased when you delete it.
GPA/CGPA calculator data is auto-deleted 4 years after the record was first created; editing it does not restart that clock. Clearing the calculator deletes it immediately.
A generated PDF report stays in the app's cache on your phone only until the next one replaces it; it is never uploaded to us.
"Upload from PC" sessions are auto-deleted after 20 minutes; present codes after 5 minutes.
Company entries and their logo images are kept for as long as they are useful to students; they are not deleted when the person who added them deletes their account, but that person's name and picture are removed from them (see Section 10).
Feedback you write about a company is kept until you delete it or delete your account; there is no automatic expiry. Deleting an entry removes it from our database — it is not hidden, flagged or archived.
Your to-do tasks, money entries and timetable picture are never on our servers at all, so there is nothing for us to retain or delete — they live and die on your phone (see 2.11).
No security system is perfect. While we take reasonable technical measures, we cannot guarantee absolute security, which is another reason not to upload private or confidential material.

8. Your Rights and Choices

Access: your profile, posts, comments, credit balance and calculator data are all viewable in the app. The calculator's Share button also exports everything it holds as a PDF you can keep.
Correction: you can edit your name, department, batch and semester at any time.
Deletion of content: you can delete any post, file or comment you created, and any company feedback you wrote — feedback additionally has an Edit button, so a mistake can be corrected rather than only removed (see 2.7). For calculator data, tapping Clear deletes the record from our servers immediately.
On-device tools: your to-do list, money tracker and timetable are deleted by removing the entry, task or picture in the app, or by clearing the app's storage or uninstalling it. Nothing needs to be requested from us, because we never held any of it.
Deletion of account: you can delete your entire account and data (Section 10).
Withdraw permissions: camera, microphone, notification and storage permissions can be revoked at any time in Android Settings → Apps → My GCT Hub → Permissions. The rest of the app keeps working.
Ask us: for any request or question, email ragavan.devp@gmail.com; we reply within a reasonable time, normally 48 hours.

9. Children's Privacy

My GCT Hub is intended for college students aged 13 and above. We do not knowingly collect data from children under 13. If you believe a child under 13 has created an account, email us and we will delete the account and its data promptly.

10. How to Delete Your Account and All Your Data

You can delete your account yourself, at any time, directly inside the app. You do not need to email us, ask permission, or give a reason. Deletion is immediate, permanent, and cannot be undone.

Step-by-step (inside the app)

Open My GCT Hub and sign in.
On the home screen, tap your profile picture (top-left) or the settings gear icon (top-right) — both open your profile and settings screen.
Scroll to the bottom of that screen and tap Delete Account — the red icon directly below Logout.
A confirmation sheet appears listing everything that will be destroyed. Read it, then tap Delete — or tap Stay to cancel with nothing removed.
For safety, you are then asked to type the exact phrase delete my account into a text box. The final button stays disabled until the phrase matches, so the account cannot be deleted by an accidental tap.
Tap Delete Forever.

Your data is erased from our servers straight away and you are returned to the login screen. There is no waiting period, no "deactivated" state, and no way for you or for us to restore the account afterwards. If you want to use the app again later, you must create a new account from scratch.

Exactly what is deleted

Deleting your account permanently removes all of the following from our servers:

Data	What happens
Your profile	Name, email address, profile picture link, department, batch and semester — the account record itself is destroyed.
Everything you uploaded	Every PDF, note, question paper, syllabus and reference book you posted is deleted, including the actual files and cover images removed from our file storage — not just the database entry.
Your comments	Every comment you wrote anywhere in the app is deleted, along with any comments left on the posts you had uploaded.
Your likes and favourites	All "relevant"/"not relevant" marks and saved favourites are removed.
Your view history	Every record of which posts you opened is deleted.
GPA / CGPA calculator data	Your saved subjects, credits, grades and results are deleted immediately, rather than waiting for the normal 4-year auto-delete. Any PDF report you already shared with someone stays with them — we cannot recall it.
Credit points	Your point balance and lifetime earnings are erased. Redeem any points before deleting — they cannot be recovered.
Notification token	Your device's push token is deleted, so you stop receiving notifications from the app entirely.
Upload-from-PC sessions	Any temporary upload link you had open is invalidated and removed.
Your company feedback	Every piece of feedback you wrote anywhere in the Companies section is deleted — including any you had not already removed yourself.
Reports you filed	Every report you submitted about someone else's post is deleted, along with any reports filed about the posts of yours that were just removed.
Your name on the placement board	Companies you added are not deleted — a drive is information the whole college reads, and removing it would take it away from every other student. What is removed is your name, picture and role from it: the "created by" and "last edited by" credits are cleared, so nothing on the board points to you any more.

Nothing belonging to you is kept, archived, anonymised, or retained in backups for later use. We do not keep a shadow copy of deleted accounts.

Your to-do list, money tracker entries and timetable picture are not in this list, for one reason: they were never sent to us. They are on your phone only, and they are removed by uninstalling the app or clearing its storage (see 2.11).

One thing we cannot reverse: if another user already downloaded a PDF you shared, that copy lives on their own device and is beyond our reach. We delete our copy completely, but we cannot recall files that have already left our servers. Please keep this in mind before uploading anything.

If you cannot access the app

If you have uninstalled the app or cannot sign in, email ragavan.devp@gmail.com from the email address registered to your account, with the subject "Delete my account". We verify that the request comes from the registered address and then delete the account and all of the data listed above. We action these requests within 7 days, and normally within 48 hours, and email you once it is done.

11. Deleting Individual Posts (Without Deleting Your Account)

If you only want to remove one item rather than your whole account, open the post, tap the ⋮ menu on it, and choose Delete. This option appears only for posts you uploaded yourself. The post record and its PDF and cover image are permanently removed from our servers — the same erasure applied during account deletion, just for that one item. Comments can be deleted individually the same way by whoever wrote them.

Your account, and everything else you have shared, is unaffected.

12. Reporting Content, Copyright and Takedown Requests

All content is uploaded by student users. If you find content that is copyrighted, pirated, offensive, misleading, or that exposes your personal information, please report it and we will remove it.

Reporting from inside the app (fastest)

Open the post or book you want to report.
Tap the ⋮ menu on it and choose Report.
Pick the reason that fits — copyrighted or pirated material, contains someone's private information, offensive or inappropriate, spam or misleading, wrong or poor quality material, or something else.
Add details if you want to (optional), then tap Send Report.

What we record when you report: which post you reported and its type, who uploaded it, your user ID, the reason you chose, and any details you typed. We store this so a moderator can act on the report and so repeated problems with one uploader are visible. Your name is not shown to the person you reported — reports are not public and the uploader is not told who reported them. You can report the same post only once; reporting it again simply updates your existing report.

If the app cannot reach our servers when you tap Send, it opens your email app with the report pre-filled instead, so your report still reaches us.

Reporting something in the Companies section

The in-app Report button covers posts and books. For anything in the Companies section — a piece of feedback, or a company entry with wrong or improper information — please email ragavan.devp@gmail.com with the company name and what the problem is. We remove or correct it on the same terms as everything else, normally within 48 hours. This is the route for all of these:

Your own feedback, if you cannot reach the app to delete it yourself — though the Delete button on your own entries is the faster route.
Feedback that names an interviewer, breaks an NDA, or contains someone's personal details.
Feedback that is abusive, defamatory, or plainly false about a company.
A company representative asking us to correct or remove an entry about their firm, including its logo. We do not need proof of a trademark complaint to act — if a company asks us to take their name and logo down, we take them down.
Eligibility or salary figures that are wrong and could mislead students.
A preparation link that goes somewhere it should not — a site that is unsafe, adult, deceptive, or that hosts copyrighted or leaked material. Links are typed in by students and are not checked by us, so this is the only way we learn of a bad one.

Reporting by email

You can also email ragavan.devp@gmail.com — this is the right route if you are not a user of the app, for example a rights holder or someone whose personal information appears in an upload. Please include:

A link to, or a clear description of, the post or file concerned;
The reason (copyright infringement, privacy violation, offensive content, etc.);
If you are a rights holder: proof of your ownership of the work;
If it is your personal information: a description of what appears and where.

We review every report and, where the complaint is valid, remove the content — normally within 48 hours of receiving the report. Repeat offenders have their accounts suspended or deleted. We take no responsibility for the content of user uploads, but we do take responsibility for removing violating content promptly once it is brought to our notice.

13. Content Rules for Users

By uploading to My GCT Hub, you confirm that you have the right to share the file, and you agree NOT to upload:

Copyrighted books, paid courses, or pirated study material you do not own the rights to;
Any document containing another person's personal details (marks, phone numbers, addresses, ID cards, photos) without their consent;
Confidential or internal college documents;
Obscene, abusive, hateful, defamatory, or unlawful material;
Anything presented as an official GCT communication.

In the Companies section specifically, you additionally agree not to:

Name or describe an individual interviewer, employee or fellow candidate;
Post questions, test papers or process details you were told were confidential or signed an agreement not to share;
Post abusive, defamatory or knowingly false claims about a company or its staff;
Present an eligibility figure, package or drive date as official, or invent one;
Upload a logo you know the company objects to being used;
Add a preparation link to anything unsafe, adult, deceptive or pirated, to leaked question papers you were not allowed to share, or to a page that asks students for their login details, money or personal information.

You can edit or delete your own feedback afterwards, but anyone who read it in the meantime has already read it — so please read it once before you send it (see 2.7).

Violating uploads are removed and the responsible account may be permanently banned.

14. Changes to This Privacy Policy

We may update this policy from time to time. The "Last Updated" date at the top always reflects the current version, and significant changes will be announced in the app or on our website. Continuing to use the app after an update means you accept the revised policy.

Summary in one line: My GCT Hub is an independent student project that is not an official GCT app, all posts are uploaded by students and are not the app's own content, we collect only what each feature genuinely needs, we never sell your data, and you can delete your content or your entire account at any time.
