Privacy Policy

The short version Your bills, customers, stock and amounts are kept on your own phone or computer. To sign in, your email (and your name, if you use Google) is kept on our server.

What stays on your device

The app keeps your business records in your browser or app storage on the device you use (technically, IndexedDB):

If you uninstall the app or clear your browser data without a backup, these records are gone. That is why the app reminds you to take a backup.

Your mobile number is saved on your device as your shop's identity. It reaches our server only through usage sharing, a catalogue order or an enquiry.

Our server is a Supabase database in Mumbai, India. Database rules allow only the devices joined to your shop to read your cloud books. We do not sell your data and we do not open your books, except to help you when you ask for support.

Outside services

Backups

A backup file is created by you and kept wherever you choose: your phone, your computer, WhatsApp or Google Drive. If you put a password on it, it is encrypted (AES-GCM) and cannot be opened without that password. Cloud backup, when you turn it on, keeps a copy in a private storage area of our server that only devices joined to your shop can read.

Permissions the app asks for

Advertising and tracking

There are no ads, no advertising networks, no analytics SDKs and no third-party trackers in My Shop Diary.

How long we keep it

Children

My Shop Diary is a tool for running a business and is not intended for anyone under 18.

Your rights

Keeping it safe

The app and website are served only over HTTPS with a strict Content-Security-Policy. You can lock the app with a PIN or fingerprint. Server access is limited by database rules for each shop, and administrator access uses a separate sign-in. No app can promise it is unbreakable. Draft How and when users are told about a data breach is to be confirmed.

Changes

If this policy changes, the date at the top changes with it, and the new version appears at this same address.
