No data is collected. This app does not collect, transmit, store, or share any personal information. There are no accounts, no sign-ins and no analytics, and the app makes no network requests. The About screen offers links to the developer’s website and email address; following one opens your own browser or mail app, and nothing is sent unless you choose to.
Local storage only. The app saves your preferences to your device’s local storage:
- Your selected day-of-week name system (Earth / Numerical / Mars Planetary)
- Your selected hemisphere view (Northern / Southern)
- If you add the home-screen widget: whether that widget is expanded
- If you add the home-screen widget: which notation level you last selected
These values never leave your device. They are stored solely to restore your preferences when you reopen the app.
No third parties. No third-party SDKs, advertising networks, or data brokers are used.
