Privacy Policy

Version 2.1Updated Oct 28, 2025

01. Core Principle

We do not collect, store, or sell your data. We have no servers to store it, and no analytics scripts to track it.

Your financial data lives exclusively on your device's local storage (SQLite). If you delete the app, your data is gone forever unless you have exported a manual backup.

02. Data Collection

  • Personal InfoWe do not collect names, emails, or phone numbers. There is no account creation process.
  • Financial InfoAll transactions, budgets, and categories are stored locally on your device.
  • Usage DataWe do not use Google Analytics, Mixpanel, or Firebase. Zero tracking.

03. Android Permissions

We request specific permissions only when necessary for local functionality:

USE_BIOMETRIC

Used for App Lock authentication via your device's secure hardware. We strictly receive a "Success" or "Fail" signal. We never access your biometric data.

POST_NOTIFICATIONS

Strictly for local scheduled reminders. Triggered by your phone's system clock, not a server.

READ/WRITE_STORAGE

Required only if you explicitly choose to export or import a JSON backup file.

04. Third Parties

We do not share data with third parties because we do not have any data to share. The app contains no ad networks and no affiliate tracking pixels.
