In short: your sky belongs only to you

MoodStars is an offline-first personal mood journal where each check-in becomes a star on your night sky. Log how you feel throughout the day on a gentle -2 to +2 scale (in 0.5 steps from --, -, neutral ○, +, to ++), browse your monthly sky history with each day's average star and subtle background stars, and revisit any past day in detail. It has no user accounts, no cloud servers, no analytics, no advertising, and no internet permission. Everything you log stays strictly on your own device unless you choose to export or back it up yourself.

1. Data Stored on Your Device

When you place a star in MoodStars, the app records:

  • The mood value (a number from -2 to +2 in increments of 0.5, corresponding to --, -, ○, +, and ++).
  • The local date and time of the check-in.
  • Your app preferences (selected display language: English, French, or German, and daily reminder time).

All entries are stored in a local SQLite database inside the application's private storage folder on your Android device, with automatic schema migrations so app updates preserve your history. We do not have access to this database and never transmit it to any server.

2. Backups & CSV Export / Import

  • Android Auto-Backup: Standard Android system backup is enabled (android:allowBackup="true") so that you do not lose your journal if you switch phones. This backup is governed by your own device and Google account settings.
  • CSV Export & Import: From the Parameters tab, you can export your mood stars to a .csv file or import a previously saved .csv file. Exported files are shared only with the destination app or folder you explicitly pick.

3. Device Permissions

MoodStars requests only the minimum permissions required for its optional daily reminders:

  • POST_NOTIFICATIONS – to display your optional daily reminder notifications on your phone.
  • RECEIVE_BOOT_COMPLETED – to reschedule your daily reminder alarms after your phone restarts.

MoodStars does not request INTERNET, location, camera, microphone, or contacts permissions.

4. Third-Party Services & Tracking

MoodStars contains no third-party analytics SDKs, crash reporters, trackers, or advertising networks. No personal or usage data is collected, sold, or shared with third parties.

5. Deleting Your Data

Because all data lives locally on your device, you have full control over it at all times. Once placed, mood stars remain as an authentic record of your sky; you can erase all data at any time by clearing the app's storage in your Android system settings or uninstalling the app.
