Privacy Policy

PrepLift helps school students with homework, mainly through WhatsApp. Most of our users are children. That shapes everything below: we collect as little as the service can work with, we do not keep homework photographs at all, and we do not sell anything about anyone.

This policy covers both the WhatsApp service and the PrepLift web platform. It is written to be read, not to be survived — if anything here is unclear, write to us and we will explain it.

1. Who we are

PrepLift (“we”, “us”) operates the PrepLift WhatsApp service and the website at preplift.in. For the purposes of India’s Digital Personal Data Protection Act, 2023, we are the Data Fiduciary for the information described here.

2. Information we collect

On WhatsApp

• Your WhatsApp phone number. This is the account. There is no separate login.
• Your class and board (for example, Class 8, CBSE), so answers match the right syllabus.
• Your preferred language.
• The text of questions you ask, and the answers we send.
• Which topics you asked about, so we can tell you what you are strong and weak at.
• Practice answers you send and whether they were correct.
• A parent or guardian’s phone number, only if it is given to us for weekly reports.

What we do NOT keep

Homework photographs are never stored. A photo you send is read in memory to extract the question, passed to the solver, and discarded when the answer is sent. It is not written to disk, not saved in our database, and not retained in any backup. The same applies to voice notes and PDFs.

We keep the extracted text of the question, because that is what lets us show you your own progress. We do not keep the image it came from — a homework photo carries handwriting, sometimes a name, sometimes a school crest, and none of that is needed to teach anybody anything.

On the web platform

• Name and email address, if you create an account.
• Answers you submit and your results.
• Basic technical logs (IP address, browser type) for security and debugging.

3. How we use it

• To read your question and produce a solution.
• To explain a step again, differently, when you ask.
• To remember which concepts you find difficult, so explanations and practice questions can target them.
• To send you a weekly reminder, if you have not turned it off.
• To send a weekly summary to a parent, only where a parent’s number has been provided.
• To count your free questions and manage your subscription.
• To keep the service safe and working.

We do not use your data for advertising, and we do not sell or rent it to anybody.

4. AI processing

Questions are solved using third-party artificial intelligence services. To do that, the text of your question — and, for diagram questions, the image — is sent to those services for processing. They are used for three things only: reading the question, producing the solution, and generating the spoken version when you ask for one.

We send only what is needed to answer the question. Your phone number, your name and your history are never included. Our providers are engaged under terms that prohibit them from using your content to train their models.

We keep a current list of the sub-processors we use and will share it on request — write to privacy@preplift.in. We publish it that way rather than inline so the list stays accurate as providers change, instead of going stale on a page nobody re-reads.

AI can be wrong. Where the system is not confident, it says so and tells you to check with your teacher. Please do — a solution from PrepLift is study help, not a guarantee.

5. Children’s privacy

This service is intended for school students, and we assume our users are children. Under the DPDP Act, processing a child’s personal data requires verifiable consent from a parent or guardian, and we do not undertake tracking, behavioural monitoring or targeted advertising directed at children. We do not do any of those things for anyone.

Specifically, for every user we treat as a child:

• We never ask for a full name, home address, school name, age or date of birth.
• We never ask a child to move the conversation anywhere else, or to contact anyone privately.
• We do not build advertising profiles, and we run no third-party advertising or tracking pixels in the WhatsApp service.
• If a message suggests a child may be unsafe or in distress, the service stops helping with homework and directs them to a trusted adult and to CHILDLINE (1098). We record that this happened so a person can review the account; we do not use it for any other purpose.

A parent or guardian may ask us at any time to show, correct or delete everything we hold about their child. Write to the address in section 10 from the phone number or email associated with the account.

6. Sharing

We share information only with:

• Meta (WhatsApp), necessarily — the conversation happens on their platform, under their own privacy terms.
• AI and cloud infrastructure providers, as described in section 4, and for database and file hosting. All are bound by contract to process data only on our instructions. The current list is available on request.
• Our payment processor, to take payments. Card and UPI details go to them directly and never reach our servers.
• A parent or guardian, where a number has been provided for weekly summaries.
• Authorities, where we are legally required to.

7. Retention

• Homework photos, voice notes and PDFs: not retained at all.
• Question text and topic history: while your account is active, so your progress means something.
• Payment records: as long as Indian tax and accounting law requires.
• On deletion: your account and everything linked to it — questions, progress, practice attempts, activity — is removed.

8. Security

Traffic is encrypted in transit. Database access is restricted at the row level so one student’s data is not reachable through another’s session, and webhook requests are cryptographically verified before we act on them. No system is perfectly secure, and we will not claim otherwise; if a breach affects you, we will tell you and the Data Protection Board as the law requires.

9. Your rights

Under the DPDP Act you may:

• Ask what we hold about you and why.
• Have it corrected or completed.
• Have it erased.
• Withdraw consent — message stop on WhatsApp to end reminders, or ask us to close the account entirely.
• Nominate someone to exercise these rights on your behalf.
• Complain to the Data Protection Board of India if we get it wrong.

10. Contact

Privacy questions, data requests and account deletion: privacy@preplift.in. We aim to respond within 5 business days, and in any case within the period the law allows.

11. Changes

If we change this policy we will update the date at the top, and for anything significant we will say so in the WhatsApp chat rather than expecting you to come back and re-read this page.
