6. Screen Time API (Sleep Session Feature)

piliq uses Apple's Screen Time API (FamilyControls framework) to power the Sleep Session feature, which blocks distracting apps during your sleep time.

A. What we access: FamilyActivitySelection — an opaque token generated by iOS that represents your selected apps. piliq cannot read the actual app names, bundle identifiers, or any app metadata from this token.

B. Storage: Stored only on your local device (iOS secure storage). Never transmitted to our servers.

C. What we do not collect: App names, usage duration, launch count, or any app activity data.

D. Third-party sharing: None. This data never leaves your device.

E. Deletion: When you uninstall piliq, the FamilyActivitySelection token and all related data are automatically removed from your device.

7. Google Analytics for Firebase

piliq uses Google Analytics for Firebase (“GA4”) to collect anonymous usage analytics to improve the Service.

A. What we collect: App events (e.g., feature usage, screen views), session information, device type, and Firebase Installation ID (a device-level pseudonymous identifier generated by Firebase). No personally identifiable information is included.

B. No account required: Analytics data is collected at the device level via Firebase Installation ID. This means GA4 receives data even if you have not registered or logged in — the data is anonymous and cannot be linked to a specific user.

C. Data transmission: Analytics events are sent to Google's servers in the United States and are subject to Google's Privacy Policy.

D. Opt-out: You can disable analytics collection by turning off “Share Usage Data” in the app settings.
