Muyu Mind

Privacy Policy

Effective date: June 26, 2026

This Privacy Policy explains how Muyu Mind handles information when you use the mobile application. Muyu Mind is a wooden fish and piano-prayer app that may display advertisements.

By using Muyu Mind, you agree to the collection and use of information described in this Privacy Policy.

1. Information We Collect

Muyu Mind is designed to work without requiring a user account. We do not ask you to provide your name, email address, phone number, payment information, or other directly identifying personal information to use the basic app features.

The app may store the following information locally on your device:

  • Daily and lifetime tap counts.
  • Your selected wooden fish skin, sound, piano piece, and app settings.
  • Preferences such as sound, haptics, reduced motion, and reset options.

If you contact us by email, we may receive your email address and any information you choose to include in your message.

2. Advertising and Third-Party Services

Muyu Mind contains advertisements. Ads may be provided by third-party advertising services, such as Google AdMob or similar ad networks. These third-party services may collect and process information from your device to provide, measure, limit, and improve ads.

Depending on the advertising provider and your device settings, advertising services may collect information such as:

  • Advertising identifiers, such as the Android Advertising ID.
  • Device information, app information, operating system, language, and general region.
  • Ad views, ad interactions, approximate usage data, diagnostics, and crash-related information.
  • IP address or other network information used for security, fraud prevention, and ad delivery.

Advertising partners may use this information to show contextual or personalized ads, measure ad performance, prevent fraud and abuse, and comply with legal obligations. Their collection and processing practices are governed by their own privacy policies.

You can learn more about how Google uses information from apps that use its services at Google's partner sites and apps policy, and you can learn more about Google advertising at Google Advertising.

3. How We Use Information

We use information for the following purposes:

  • To provide the app's tap counter, progress, sound, haptic, and piano-prayer features.
  • To remember your app settings and preferences on your device.
  • To display and support advertisements.
  • To respond to support requests if you contact us.
  • To maintain, protect, and improve the app.

4. Data Storage and Retention

Tap counts, selected skins, selected piano pieces, and settings are stored locally on your device. You can reset certain app data inside the app, and you can remove app data by uninstalling the app or clearing the app's storage through your device settings.

Third-party advertising services may retain information according to their own policies. Please review the relevant third-party privacy policies for more details.

5. Sharing of Information

We do not sell the basic app data stored locally by Muyu Mind. We may share information only in these limited situations:

  • With advertising providers that help display ads in the app.
  • With service providers that help operate, maintain, or improve the app, if such services are added.
  • If required by law, regulation, legal process, or a valid government request.
  • To protect the rights, safety, and security of users, the app, or others.

6. Your Choices and Controls

You may be able to control advertising-related information through your device and account settings:

  • You can reset or delete your Android Advertising ID in your Android privacy or ads settings, depending on your device version.
  • You can adjust ad personalization settings through your Google account or device settings where available.
  • You can uninstall the app at any time to stop further app-related data storage on your device.

Some ads may still be shown even if personalized ads are disabled, but they may be based on contextual information rather than a personalized advertising profile.

7. Children's Privacy

Muyu Mind is not directed to children under the age of 13, and we do not knowingly collect personal information from children under 13. If you believe that a child has provided us with personal information, please contact us so we can take appropriate action.

8. Security

We use reasonable efforts to protect information associated with the app. However, no method of electronic storage, transmission, or mobile app operation is completely secure, and we cannot guarantee absolute security.

9. International Users

Muyu Mind may be used by people outside the country where the app developer is located. If you use the app from another country, you understand that information handled by advertising providers or service providers may be processed in countries with different data protection laws.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we make changes, we will update the effective date at the top of this page. Your continued use of Muyu Mind after a policy update means you accept the updated Privacy Policy.
