Privacy Policy

Last updated: March 2026

1. General

StreakTracker was built with privacy as a core principle. The app operates entirely on your device — no accounts, no cloud sync, no external servers. All your streaks, goals, and habits are stored only locally on your device and are never transmitted anywhere.

3. Data Collected

StreakTracker does not collect, store, or process any personal data. Specifically:

  • No name, email address, or user account is created
  • No location, device identifiers, or usage analytics are collected
  • No data is transmitted to any server
  • No third-party analytics or advertising SDKs are used

All data you enter into the app (streak names, check-ins, settings) is stored exclusively in the local storage of your device using AsyncStorage.

4. PIN Lock & Biometrics

If you choose to enable the optional PIN lock or biometric authentication, these credentials are stored exclusively on your device in its secure local storage. The PIN is never sent to any server and is only processed locally to unlock the app.

5. Push Notifications

StreakTracker can send local push notifications to remind you of your daily habits. These notifications are scheduled locally on your device through the operating system. No notification data is transmitted to external servers.

6. This Website

This website (streaktracker.app) is a static informational page and does not use cookies, tracking pixels, or analytics tools. No personal data is collected when you browse this website.

Under the General Data Protection Regulation (GDPR), you have the following rights regarding your personal data:

  • Right to access (Art. 15 GDPR)

  • Right to erasure (Art. 17 GDPR)
  • Right to restriction of processing (Art. 18 GDPR)
  • Right to data portability (Art. 20 GDPR)
