Privacy Policy

Last updated 15 October 2026

Chalkpis ("we", "us") is built and run by M2W Technologies Private Limited (Man2Web), India. This policy explains what information the Chalkpis app and website handle, why, and the choices you have. If anything here is unclear, write to hello@chalkpis.com.

Who this covers

Teachers and centres who sign up for Chalkpis ("you"): tuition and coaching centres, abacus, karate, dance, yoga and music classes, sports academies and the like; the helpers they invite; and the students and parents whose details a centre adds to the app.

For student and parent details, the teacher or centre decides what is entered and why; we process those details on the centre's behalf to run the service.

Information we collect

About you: your name, mobile number, institute name, address, phone, logo, UPI id and payment link (if you add them), and your plan.

Sign-in: you sign in with your mobile number and a code sent on WhatsApp. Sign-in codes are stored only as one-way hashes and expire within minutes.

About your students and their parents, as entered by you: names, class, batches, parent name and mobile number, optional student phone, date of birth, gender, photo and notes; attendance; fees, discounts, payments and receipts.

Messages: a log of WhatsApp messages sent to parents (type, time, status and the last 4 digits of the number). The message values are deleted once a message is sent or has failed.

Technical: sign-in sessions and basic server logs needed to keep the service secure. We do not use advertising trackers and we do not sell personal data.

How we use it

To run the app for you: keep student records, attendance and fees, make receipts and reports, and show parents their child's details on a private link you choose to share.

To send WhatsApp messages you have switched on or asked for (absent and late alerts, fee reminders with your UPI QR or payment link, receipts, parent page links) and your sign-in codes.

To keep the service safe, fix problems and meet legal duties.

Who we share it with

WhatsApp messages are sent from our business number through the WhatsApp Business Platform (Meta) and our messaging partner ValueFirst Digital Media. They receive the parent's number and the message text needed to deliver it.

Our servers are hosted by our cloud provider. App updates are delivered through Expo (EAS).

Plan payments on our website are handled by Razorpay. Subscriptions in the iPhone and Android apps are handled by Apple (App Store) or Google (Google Play), and their status reaches us through RevenueCat, which receives your centre's account number in Chalkpis and the purchase details (never your card, UPI or bank details). We never see your card, UPI or bank details.

Tuition fees go straight from parents to your own UPI id or payment page. Chalkpis never receives or holds that money.

We share information with authorities only when the law requires it.

How long we keep it

We keep your data while your account is open. When you delete your account (Account > Delete my account), your institute, students, attendance, fees, messages and pictures are removed from our live systems straight away.

Encrypted backups are kept for up to 14 days and then deleted. Plan payment records may be kept longer where tax law requires it.

Security

All traffic is encrypted (HTTPS). Every record belongs to one institute and the server checks that on every request, so one centre can never see another centre's data. Parent links are long secret links that you can switch off at any time; parent pages never show phone numbers or notes.

Children

Chalkpis is used by teachers and centres, not by children. Centres add student details for their classes and fee records and are responsible for having the parent's consent to do so and to message them on WhatsApp, as required by the Digital Personal Data Protection Act, 2023.

Your choices and rights

You can see, correct or delete the details you entered at any time in the app, and switch parent messages off (for everyone or for one student).

Parents and students can ask their teacher or centre to correct or remove their details, or write to us and we will help the centre do so.

You can delete your account in the app at any time.

Changes

We may update this policy. We will show the new date at the top and tell you in the app if the changes are important.
