Privacy Policy

1. Information We May Collect

Depending on how you use the app, we may receive the following categories of information:

• Information you provide directly, such as your email address, support messages, or feedback submitted to us.
• Technical and usage information, including device model, operating system version, app events, crash logs, and diagnostic details.
• Advertising-related identifiers, where permitted by your settings and applicable platform rules.

2. Photo, Video, and File Access

The app offers storage cleaning and media management features. To detect duplicate items, similar media, large videos, or other unnecessary files, the app may analyze content stored on your device.

• Your photos, videos, and file contents are not uploaded to our servers for cleaning analysis.
• We do not keep a cloud backup or server-side copy of your private media for these functions.
• Your media is not used for advertising profiling or model training.
• Deletion or cleanup actions occur only after you review and confirm them.
• Limited metadata, such as file size, media duration, or creation date, may be used only to support app features.

3. Advertising and Tracking

We may display advertisements in the app. On Apple devices, we may request permission through App Tracking Transparency before accessing the Identifier for Advertisers (IDFA).

• If permission is granted, advertising partners may use certain data to measure campaign performance and improve ad relevance.
• If permission is denied, advertisements may still be shown, but they may be less tailored to your interests.
• You can change your tracking choice in your device settings at any time.

4. Analytics and Stability Services

We may use analytics and crash reporting tools, including Firebase services, to better understand app performance, identify bugs, and improve overall reliability.

• Screen views and feature interactions
• App launch events and general usage patterns
• Error logs, crash reports, and related diagnostics

5. How Information Is Used

Information described in this policy may be used to:

• Provide and maintain the app’s core features
• Respond to support requests and user inquiries
• Improve functionality, stability, and performance
• Measure advertising effectiveness
• Send important notices related to the service, where appropriate

6. Third-Party Services

The app may integrate third-party SDKs or service providers, such as analytics, crash reporting, advertising, or subscription infrastructure. Those providers may process certain information according to their own privacy terms.

7. Purchases and Subscription Status

In-app purchases and subscriptions are processed by Apple. We do not receive or store your bank card information. We may access limited purchase status information only to determine whether premium features should be enabled.

8. Sharing and Disclosure

We do not sell your personal information. Information may be disclosed only when reasonably necessary to comply with law, enforce our rights, respond to lawful requests, or protect users and the service.

9. Children’s Privacy

The app is not intended for children under 13 years of age. We do not knowingly collect personal information from children. If you believe a child has provided information to us, please contact us so we can review and take appropriate action.

10. Data Retention and Your Choices

We keep information only for as long as needed for the purposes described here, unless a longer retention period is required by law. Depending on your region, you may have rights to request access, correction, deletion, or restriction of certain personal data.

11. Policy Updates

We may revise this Privacy Policy from time to time. Any update will be posted on this page together with a new effective date. Continued use of the app after changes become effective means you accept the updated policy.
