Privacy Policy

Flip Clock — package name com.flipclock.ruichmedia

Summary: Flip Clock is a simple, offline clock application. It requests no system permissions, does not collect, store, or transmit any personal data, and contains no advertisements or third-party analytics.

1. Information We Collect

We do not collect any personal information. Flip Clock runs entirely on your device. The app does not require an internet connection, an account, or any login. None of the following is gathered, stored, or shared:

Your name, email address, phone number, or any contact details;
Your location (precise or approximate);
Your device identifiers, advertising ID, or IP address;
Your usage, browsing, or interaction analytics;
Any photos, files, contacts, or calendar data.

2. Permissions

Flip Clock declares zero permissions in its Android manifest. All features work with capabilities already available to any app on your device:

The clock, date, and lunar calendar are computed locally on the device;
Screen brightness adjustment uses the standard Android window brightness API and does not require any special permission;
Opening the system alarm application uses a standard Android intent and hands control to the system app — Flip Clock never reads, writes, or manages your alarms itself;
Theme, language (English / 中文), 12/24-hour format, and brightness preferences are saved only in your device's private local storage (SharedPreferences) and never leave the device.

3. Data Storage & Sharing

All preferences (theme, language, time format, brightness) are stored locally on your device and are accessible only to Flip Clock. We do not upload, sync, or share this information with us or any third party. We have no servers that receive data from the app.

4. Children's Privacy

Flip Clock is safe for users of all ages and does not target children specifically. Because the app collects no data at all, it complies with children's privacy regulations (such as COPPA and GDPR-K) by design.

5. Security

As Flip Clock does not transmit or store any personal data, there is no personal information that could be lost, intercepted, or compromised.

6. Changes to This Policy

If the app ever changes in a way that affects privacy (for example, by adding a network feature or a third-party SDK), this policy will be updated and the new version posted here with a revised effective date.
