Most apps promise to protect your data. Paisa takes the shorter route: it never collects any.
Household spending is among the most revealing data a person produces. Where you shop, what you eat, when someone in the house was ill, who supports you and whether they were late. That is not a dataset worth handing to anybody.
A privacy policy is a promise. This is a property of how the thing is built.
Your entries are written to the browser storage inside the app on your phone. That store is private to this one app on this one device. No other app can read it, and nothing copies it anywhere.
So it can warn you when you cross a limit, or nudge you in the evening to log the day. Android also requires the internet permission for the app's own display layer, but the app never makes a network request — you can keep the phone in aeroplane mode permanently and lose nothing.
One tap writes a complete backup as a JSON file, or the whole history as a CSV you can open in any spreadsheet. It is your file, in an open format, on your storage. Restoring merges rather than overwrites, so bringing a backup back can never duplicate what is already there.
If you want a family member to see the accounts, the app writes a single self-contained HTML file — every figure and style inlined, no scripts, nothing loaded from the network. Send it however you like. They can read it anywhere; they cannot change it, and it never phones home.
This design costs you something. It is worth being straight about what.
| A typical finance app | Paisa | |
|---|---|---|
| Your spending data | On their servers | On your phone only |
| Sign-up | Email, phone, sometimes KYC | None |
| Works without internet | Rarely | Always |
| If the company shuts down | Your history goes with it | Nothing changes |
| Automatic bank import | Yes | No — you type it |
| Syncs across your devices | Yes | No — one phone, plus exports |
| If you uninstall | Data survives on their side | Data is gone unless you exported |
An app that imports your bank feed knows a number left your account. It does not know you ordered at eleven at night because you were tired, or that you regretted it by morning. Those two facts are what make the money recoverable, and only you can supply them.
The honest consequence of keeping everything on-device is that uninstalling deletes it. The app nags you monthly and the export takes one tap — but it is your job, and it is the one thing worth remembering.
Install it, use it offline forever, take your data with you whenever you like.
