Data Transparency

Your data.
Your control.

Starpolar is built so your private life stays yours. Here is exactly where everything goes — plain language, no surprises.

Always local

On your device

Your daily life stays on your phone. Nothing leaves unless you explicitly turn on sync.

Planning & tasks Workouts Nutrition Finance Health logs
Encrypted at rest. Only ever on your device.
Optional · off by default

When you sync

FileSync is off by default. When enabled, data travels encrypted over HTTPS and is stored encrypted in Firebase Firestore. Synced app data is only decrypted locally on your client device; it is never sent openly and never lies open on our servers. You can disable sync or delete your data at any time from within the app.

You decide when to sync. You can delete everything at any time.
Only your input

With the assistant

When you use the AI Assistant, your text or voice input is sent to the assistant backend and processed with OpenAI. Your request is interpreted using the context you provide. Your full database is never included.

Only what you type. Your database never leaves your device.

What we never do with your data

Whether you sync or not, we don't sell or share your data, and we don't use it for advertising, profiling, or training AI models.

  • Selling or sharing your data with third parties
  • Advertising or profiling based on your finance, health, or nutrition data
  • Training AI models on your full app database
  • Cross-site or cross-app tracking
  • Collecting your location outside an active cardio training session
  • Sharing your training or nutrition history with ad networks

About crash & debug reports: These are only sent if you have opted in to sharing analytics in the app settings. You can opt out again at any time. Reports contain only the affected code location, stack trace, app version, and OS version. No user data, no names, no identifiers.

You are in control.

Every sensitive feature in Starpolar is opt-in. You decide what the app can and cannot do.

  • Sync is off by default. You turn it on.
  • Delete all sync data from within the app at any time.
  • Crash reporting only if you opt in. Opt out again anytime in settings.
  • Location only when you start the Cardio Tracker.
  • Delete your account and all data permanently.
  • No ads. No tracking. No selling your data. Ever.
