What we collect
Your account details, what you tell us about your exam plans, and what you do while practising. We do not ask for anything we do not use.
When you create an account
Email address, or phone number if you sign up that way. A password, which we store only as a salted hash and can never read back. Your name, and your Google profile name, email and photo if you sign in with Google.
What you tell us about your preparation
Date of birth, class, target exam year, board, school, and city or state. Date of birth is the one we ask for specifically: Indian law treats anyone under 18 differently, and we cannot apply those protections if we do not know your age.
What you produce while using the app
- Questions attempted, answers given, time taken, hints used, and which topics you are strong or weak on
- Mock test and practice attempts, streaks, XP and trophies
- Messages you send to the AI doubt solver, and images or documents you upload to get a doubt solved
Technical data
Device token for push notifications, and standard request logs. We do not collect your contacts, your location, your photo library, or anything from other apps.
Why we collect it
To run your account, to make the practice adapt to what you find hard, and to take payment. That is the whole list.
| Purpose | What it uses | Why we may lawfully do it |
|---|---|---|
| Create and secure your account | Email, phone, password hash | Your consent, and necessary to give you the service |
| Adapt the questions to you | Attempts, accuracy, topic mastery | Your consent; this is the product you signed up for |
| Answer your doubts | Your question text and any image you upload | Your consent |
| Take payment and unlock a plan | Amount, plan, Razorpay identifiers | Necessary for the contract, and required for tax records |
| Send reminders you asked for | Device token, email, phone | Your consent; you can turn these off |
| Answer a complaint | Your correspondence | Legal obligation |
We do not show advertising to anyone, we do not sell personal data, and we do not build profiles for anyone other than you.
What the AI features send out
When you ask the AI a question, the text of that question, and any image you attach, goes to an AI provider outside India. Nothing else about you goes with it.
The doubt solver, question generation, study plans and document reading are powered by third-party AI models. We send the minimum needed to produce an answer: your question, and the image or document if you attached one. We do not send your name, email, phone number, payment details or performance history.
Depending on which model is best for the feature, that request may go to any of:
| Provider | Used for |
|---|---|
| OpenAI | Most AI features. Our primary provider. |
| Google (Gemini) | Some generation and reasoning tasks |
| Microsoft Azure OpenAI | Fallback capacity, and the OCR model that reads uploaded images |
| OpenRouter | Routing to additional models where configured |
Please do not type personal information into the AI chat. Not your own and not anyone else's. Ask the physics question, not the question with your phone number in it. We filter what we can, but the safest message is one that has nothing personal in it.
Who else sees it
A short list of companies that run parts of the service for us. Nobody else, and never for money.
| Who | What they do for us | What they receive |
|---|---|---|
| Supabase | Database, sign-in, file storage | Account data, profile picture, uploaded documents |
| Razorpay | Payments | Payment details you enter at checkout |
| OpenAI, Google, Microsoft Azure, OpenRouter | AI features | Your question text and attachments only |
| Google Firebase | Push notifications, crash and usage reporting | Device token, app events |
| PostHog | Product analytics | App events, for adult accounts only |
| Google (Gmail) | Sending transactional email | Your email address and the message |
We will also disclose data if a court or a law validly requires it. Where we are allowed to tell you, we will.
Where it is stored
Your data lives in India, in the Mumbai region. Only the AI requests and push notifications leave the country.
- DatabaseSupabase, ap-south-1 (Mumbai, India)
- Files and imagesSupabase storage, same region
- PaymentsRazorpay, in India, under RBI rules
- AI requestsProcessed outside India by the providers listed above
- Push notificationsGoogle Firebase, outside India
We do not store your card number. Razorpay handles card details directly and returns only a token, the network and the last four digits, which is what the RBI tokenisation rules require.
If you are under 18
We need a parent or guardian's details, we will write to them, and they can withdraw at any time with one click. We never run behavioural tracking on a student under 18.
Most people preparing for JEE are under 18. Section 9 of the Digital Personal Data Protection Act 2023 treats anyone under 18 as a child and requires a parent or lawful guardian to consent before we process their data.
What we do
- We ask for date of birth so we know whether this applies to you.
- If you are under 18 we ask for a parent or guardian's name and contact details, and for you to confirm they agree.
- We then email that guardian a plain description of what we collect, with a link that withdraws consent in one click and needs no account.
- We do not run third-party behavioural analytics on any account that is not confirmed to belong to an adult. The Act prohibits this for children and there is no consent that makes it allowed.
- We do not show advertising to anyone, at any age.
What still happens for a student under 18
Your practice data is still recorded, because that is the service: the app cannot adapt to what you find hard without measuring what you find hard. That is different from tracking you, and it stays inside our own systems.
For parents and guardians
You can ask what we hold about your child, correct it, or have it deleted, by writing to support@jeenius.tech. We reply within 30 days.
How long we keep it
Account and study data for as long as you have an account. Payment records for eight years, because tax law says so.
| What | Kept for |
|---|---|
| Account and profile | While your account exists. Deleting it anonymises the record. |
| Practice and progress data | While your account exists |
| AI chat history | While your account exists, unless you delete a conversation |
| Payment records | 8 years, required for tax records |
| Consent records | While your account exists plus 3 years, as evidence that consent was given |
| Support correspondence | 3 years |
Your rights
See it, fix it, delete it, or tell us to stop. Ask at support@jeenius.tech and we answer within 30 days.
- See what we hold. Most of it is in the app; ask us for the rest.
- Correct it. Edit your profile, or write to us.
- Delete your account. In the app, or by writing to us. We anonymise your record and stop processing.
- Withdraw consent for a specific purpose, such as notifications or analytics. Withdrawing consent for something the product cannot run without is the same as closing your account, and we will tell you that rather than quietly break the app.
- Complain. To our Grievance Officer first, and if that does not resolve it, to the Data Protection Board of India.
How we protect it
Encrypted in transit, hashed passwords, access controls, and a plan for when something goes wrong.
- All traffic between your device and our servers is encrypted with HTTPS.
- Passwords are stored only as salted hashes. Nobody here can read your password.
- Access to production data is limited to the people who need it.
- Card details never reach our servers.
No system is perfectly secure, and anyone who tells you otherwise is selling something. If a breach affects you we will tell you, and we will report it to CERT-In within six hours and to the Data Protection Board as the law requires.
Found a vulnerability? Write to support@jeenius.tech. We will not pursue good-faith research that respects other users' privacy.
Changes to this policy
If we change something that matters, we tell you in the app before it takes effect.
This is version 2026-08-16.1. When we change how we use your data we publish a new version and notify you in the app. Where the change needs your consent, we ask for it rather than assuming it.
