Plain language summary
"Meridian processes your location data entirely on your iPhone. We don't have servers that store your data. We don't have accounts. We don't use analytics. If you uninstall the app, your data is gone."

What Meridian accesses

Meridian requests access to three data sources. All processing happens locally on your device.

Source Permission Purpose Leaves device?
Photo Library Read-only (Limited mode available) Extracts GPS coordinates and timestamps from photo EXIF data to reconstruct past journeys Never
Apple Health Workout Routes (read-only) Reads running, cycling, and hiking routes to enrich the daily timeline Never
Location When In Use or Always (optional) Continuous tracking when you choose to enable it, to log new routes automatically Never
Reverse geocoding CLGeocoder (Apple system) Converts coordinates to place names ("Blue Bottle Coffee") for display Via Apple system only

Note on reverse geocoding: CLGeocoder is an Apple system service. Coordinate data passes through Apple's servers to return a place name — Meridian itself does not send your data to any third-party service. Apple's privacy policy applies to this lookup.

What Meridian does not collect

No account creation. No email, phone number, or Apple ID required.
No third-party analytics. No Firebase, Mixpanel, Sentry, Amplitude, or equivalent.
No crash reporting SDKs that transmit data.
No advertising or tracking SDKs of any kind.
No data sharing with third parties — because we have no data.
No access to contacts, calendar, microphone, or camera.
Uninstalling the app permanently removes all data from your device. There is no cloud copy.

Third-party services

The only external service Meridian interacts with is Apple's CLGeocoder for reverse geocoding (coordinates → place names). This is an Apple system API — not a third-party company. Meridian does not integrate any SDKs from companies outside of Apple's own frameworks.

Apple's privacy policy: apple.com/legal/privacy

Legal compliance

Meridian qualifies for Apple's "Data Not Collected" App Privacy label. Because no personal data leaves your device, Meridian falls outside the scope of GDPR's data controller requirements, and meets the local processing requirements of China's Personal Information Protection Law (PIPL).

Children's privacy

Meridian is not directed at children under 13. Since we collect no data from anyone, children are not at risk of data exposure through this app.

Changes to this policy

If we add features that require new data handling — for example, optional iCloud backup — this page will be updated with a new date and announced via the app's release notes. We will not introduce data collection silently.
