Privacy
Privacy by design
Master of Budgets was built so that your financial data never has to be trusted to anyone — including us.
No bank connection
The app never connects to your bank. There is no Plaid, no aggregator, no stored bank credentials. You enter your starting balance and log transactions yourself. This keeps your credentials private and builds the kind of awareness that actually changes habits.
Your data lives on your device
The app stores everything in a local database in your browser. Nothing is uploaded unless you explicitly turn on cloud sync. You can export your entire database as a file at any time from Settings — you own it completely.
End-to-end encrypted sync
If you enable cloud sync (a Premium feature), your data is compressed and encrypted on your device using AES-256-GCM with a passphrase only you know, before it ever leaves. The server stores an encrypted blob it cannot read. Not even the developer can access your data.
Ad free, always
Master of Budgets does not run ads, does not sell data, and does not track your spending for any purpose. The business model is simple: a small optional subscription to support future development and cloud sync. That's it.
Budget without giving up your privacy.
