1. Our Zero-Knowledge Philosophy
Focus Flow is designed with a local-first, privacy-by-default architecture. We believe your productivity patterns, reflections, and deep work logs are deeply personal. We do not sell, rent, or monetize your data. Any cloud backup features are strictly opt-in, designed to let you keep your progress safe.
2. Apple Screen Time API & App Shielding
Our Deep Focus Shield feature relies entirely on Apple’s native Family Controls framework. This API enables system-level shielding of distracting apps and categories on-device:
- All selection and blocking lists are processed strictly on-device by iOS.
- Focus Flow has no access to your list of installed apps, nor do we track what websites or apps you block.
- Shielding logs never leave your physical iPhone.
3. Apple Calendar Sync
When you enable Calendar Sync, Focus Flow requests local access to write completed sessions as events on your native calendar:
- All calendar actions are carried out on-device using iOS services.
- We only write events to the dedicated "Focus Flow" calendar category that we create with your permission.
- We do not scan, read, collect, or upload your existing calendar events, schedules, or meetings.
4. Data Synchronization & Backup
If you choose to register an account using Email, Sign in with Apple, or Sign in with Google, Focus Flow securely backs up your stats and settings:
- Data Synced: Completed session durations, focus modes (e.g. Work, Zen), optional session reflections/intents, daily focus goals, and ambient sound mixer volumes.
- Security: All communication between the app and our secure backend is encrypted via HTTPS with TLS 1.3 and AES-256 protocols.
- Control: You retain complete ownership. You can instantly wipe all local data and permanently purge your backup account from the server directly in the settings menu of the app.
5. Third-Party Analytics & SDKs
Focus Flow values an uninterrupted, distraction-free environment:
- We do not deploy invasive marketing SDKs (such as Facebook Analytics, Google Analytics, or Adjust) inside the app.
- No cookies or background tracking scripts are active on this landing page.
- Payment details for our premium subscriptions are routed entirely through the secure Apple App Store system; we never collect or view your credit card details.
6. Your Rights & Compliance
We comply fully with Apple’s App Store Review Guidelines, the General Data Protection Regulation (GDPR), and the California Consumer Privacy Act (CCPA). You can contact our support team at any time to request data reports or support assistance.
