EternisWatch does not collect, track, sell, share, or transmit personal data, analytics, or user information. Core clock, calendar, GMT, and moon-phase features operate locally on your device using device time, timezone settings, bundled reference data, and local calculations.

App preferences, such as GMT offsets, bezel positions, appearance settings, widget settings, and Pro unlock status, are stored locally on your device using Apple system storage. Some settings are shared locally between the app and its widget extension. EternisWatch does not operate its own server or retain this information. You can remove local app data by deleting the app.

EternisWatch uses Apple StoreKit for optional in-app purchases. Apple processes purchases and may handle purchase information under Apple’s own privacy policy; EternisWatch does not receive or store payment-card information.

Moon-phase reference times are sourced from the U.S. Naval Observatory Astronomical Applications Department and bundled for local use. The U.S. Naval Observatory does not endorse EternisWatch.

If you choose to contact support or open an external link from the app, that interaction may be handled by your email provider, browser, Apple, or the linked third-party service under its respective privacy policy.
