Duo Clock is a free clock app from M Patel, an individual developer in Eastbourne, UK. Email support@newmanpharmacy.com.
None. Duo Clock does not collect, store on a server, share, or sell any personal data. There is no account, no sign-in, no analytics, no advertising, no tracking, and no crash-reporting SDK.
Your clock settings (face, 12/24-hour, seconds, night mode, accent colour, planet choice and mirror mode) are saved only on your device. Deleting the app removes them.
The app makes no network requests and asks for no permissions. Time and sunrise/sunset estimates are worked out on the device. The planet scenes are bundled inside the app.
Duo Clock is suitable for all ages and collects no data from anyone.
