No registration is required. The app has no advertising, third-party analytics, tracking SDK, or developer-operated backend.
Your favorite cities, their coordinates and time zones, order, and display preferences are stored on your device. Device or iCloud backups may include this data. City search uses a bundled offline database. Time and solar calculations run locally; search terms are not sent to a search service.
If you grant permission, your current location is used while the app is in use to determine your locality and time zone and calculate sunrise and sunset. The app does not request background location or maintain a location history. Your current-location result is held in memory for the session. If you save it as a favorite, the locality, coordinates and time zone are stored with your favorites. You may deny or revoke permission in Settings and continue to search manually.
Map display and reverse geocoding use Apple services. Coordinates and information needed to process these requests may be sent to Apple under Apple’s Privacy Policy. The developer does not receive these location requests. This policy describes app behavior; Apple and operating-system services have their own data practices.
You can delete favorites within the app. Removing the app normally removes its local data; manage backups separately in your device or iCloud settings. If you email support, the developer receives the address and information you include and uses them to respond. Do not send passwords or precise location information unless necessary for your request.
