Privacy, in plain words

What the app stores, and where. The names, roll numbers and marks you enter are stored only in this browser, on this device. We run no server that receives them. There is no account, no sign-in, no analytics and no error reporting inside the app, and its security policy forbids it from contacting any other address. The code is open, so this can be checked.

When data leaves the phone. Only when you send it yourself: a backup file you share (locked with your passphrase), a PDF or a spreadsheet you save or share. Where it goes then is up to you and the app you share it with.

The product page. This page (not the app) counts visits with Vercel Web Analytics, which uses no cookies and does not identify you. The Work with us form sends what you type to our inbox by email; it never asks for, and should never be sent, any student information.

The law in India. The Digital Personal Data Protection Act, 2023 governs digital personal data in India. Under it, a child is anyone under 18, and an organisation that decides why and how personal data is processed is a Data Fiduciary, with duties that include reasonable security safeguards and, for children, verifiable consent from a parent (section 9). The Digital Personal Data Protection Rules, 2025, notified on 13 November 2025 (G.S.R. 846(E)), set out how this works; most of the duties apply eighteen months after notification. Their Fourth Schedule lists cases where the children's-data rules apply differently, including educational institutions processing for their educational activities or a child's safety.

What this means for this app, as a matter of design rather than legal advice: we never receive or hold your students' data, because the app has no server to send it to. The school or teacher using the app decides what is recorded and remains responsible for how it is handled, as they would be with a paper register. The app helps by keeping data on the device, locking backups, and letting you delete everything (More → About and delete).

This is not legal advice. If your school or organisation needs to know its own obligations, please ask a qualified lawyer.
