Privacy Policy

YeYang Clock / YeYang Tools

Effective date: 2026-04-17

The current version of YeYang Tools focuses on local alarms, reminders, and reliability guidance. This policy explains what information is processed in this version, why it is used, and how you can manage it.

1. Information we process

To provide alarm features, the app stores alarm details on your device, including time, label, repeat days, ringtone, challenge mode, vibration preference, and snooze duration.

To help you confirm whether alarms are more likely to ring reliably, the app reads notification permission status, exact alarm permission status, and related system setting states. These values are used only to show readiness guidance inside the app.

The current version uses Google AdMob rewarded ads so users can voluntarily watch an ad to unlock different background styles. We do not require account registration and we do not upload your alarm content.

2. How the information is used

Local alarm data is used only to create, edit, display, trigger, and restore your alarms.

Permission and system status data is used only to determine whether the alarm flow has the critical conditions it needs and to guide you to system settings when action is required.

The advertising SDK may process device identifiers, advertising identifiers, approximate location, or ad interaction information according to Google policies and your consent state in order to provide, limit, measure, and protect ad services.

If future versions add analytics, cloud sync, accounts, or other third-party services, this policy should be updated before those features are released.

3. Storage and sharing

In the current version, alarm data is primarily stored locally on your device and is not proactively uploaded to a developer server.

We do not sell personal information, and alarm time, labels, or challenge content are not uploaded to ad services for ad targeting.

Rewarded ads are provided by Google AdMob. Advertising data handling is governed by Google's terms, Google's privacy policy, and any in-app consent choices available to you.

When Android or iOS notification, exact alarm, or settings interfaces are used, they are invoked only to support reminder functionality.

4. Your choices

You can edit or delete alarm data in the app at any time, and you can disable notification or exact alarm permissions in system settings.

Where ad privacy options are required in your region, the app will show or provide access to Google's consent management flow.

If those permissions are turned off, some reminder behavior may not work as expected, especially in the background, on the lock screen, or after reboot.

5. Children, updates, and contact

The app is intended for general audiences and is not specifically directed to children. Minors should use the app with guidance from a parent or guardian where appropriate.

If you have questions or feedback about data handling or local data deletion, contact us at fupeng237@gmail.com.

When product features or data practices change, this policy should be updated accordingly and the latest published version will control.

This policy may be updated as the product changes. The current version focuses on local alarm functionality and uses Google AdMob rewarded ads to unlock optional background styles.
