LP-01 · published zero. An expense tracker that cannot see your expenses.
Finance apps read your SMS, your balance, your habits. zero reads nothing, because there is nothing to read with: 0 servers, 0 accounts, 0 analytics. Your records live in a SQLite database on your phone and go nowhere.

What it does, in plain words.
- TrackTransactions with your own categories, icons, and colors.
- SeeMonthly breakdown, pie chart, a heatmap of your daily spending, average per day.
- OweDebts both ways: who owes you, whom you owe.
- KeepLight, dark, or system theme. Any currency symbol. Your name, if you want one. It stays on the phone too.
- LeaveExport everything as one JSON file, import on a new phone, or delete it all. Gone means gone: we hold no copy, so there is no copy.
What zero cannot protect.
- Install recordGoogle Play knows you downloaded the app. That is Google's ledger, not ours.
- Device backupYour phone's backup may copy the database. Your backup, your keys, your settings.
- Your exportsExport files are yours. Where you store them is outside the app.
- Your deviceA compromised phone defeats any app. No architecture survives a rooted attacker on the same device.
The claim "collects nothing" is not a promise. It is a property of the code, and the code is public. Read it.
