1. Scope

This Privacy Policy explains how ByteSailor (Shenzhen Shuji Technology Co., Ltd.) collects, uses, and shares information when you use our websites, mobile applications, and related services (collectively, the “Services”).

If you install or use a specific ByteSailor app, the app’s store listing or in-app notice may provide additional details about data collection. If there is a conflict, the app-specific notice controls for that app.

2. Data we collect

2.1 Information you provide

  • Support communications (e.g., emails you send to support@bytesailor.com).
  • Feedback and other content you choose to submit to us.

2.2 Information collected automatically

  • Device and app information (such as device model, OS version, app version, language/region settings).
  • Diagnostics and performance data (such as crash logs and basic performance metrics) to help us improve reliability.
  • Approximate location inferred from IP address for security, fraud prevention, and localization.

2.3 App permissions and local files

Some utility apps (for example, an offline music player) may request access to local device storage/media so the app can scan and play your local files. We do not need to upload your local media to provide offline playback. Any access is limited to what the app needs to function and what you allow in your device settings.

3. How we use data

  • Provide and maintain the Services, including troubleshooting and customer support.
  • Improve app stability, performance, and user experience (for example, by fixing crashes).
  • Protect against fraud, abuse, and security incidents.
  • Comply with applicable laws and enforce our terms.

4. Sharing & disclosures

We do not sell your personal information. We may share information in the following situations:

  • Service providers: vendors who help us operate the Services (e.g., hosting, analytics, crash reporting), subject to contractual confidentiality and security obligations.
  • Legal requirements: when required by law, regulation, court order, or other legal process.
  • Safety and rights: to protect the rights, property, and safety of ByteSailor, our users, or others.
  • Business transfers: in connection with a merger, acquisition, financing, or sale of assets, subject to appropriate safeguards.

App stores and platform providers (such as Google Play and Apple) may independently collect information under their own privacy policies.

5. Cookies & similar technologies

Our website may use cookies or similar technologies for basic functionality and to understand aggregate usage. You can control cookies through your browser settings. Some features may not function properly if cookies are disabled.

6. Security

We use reasonable administrative, technical, and organizational measures designed to protect information. No security method is perfect, and we cannot guarantee absolute security.

7. Your rights

Depending on your location, you may have rights to access, correct, delete, or object to certain processing of your personal information. You may also have a right to data portability.

To submit a request, contact us at support@bytesailor.com . We may need to verify your identity before fulfilling requests.

8. Children

Our Services are not directed to children under 13 (or the age required by local law), and we do not knowingly collect personal information from children. If you believe a child provided us personal information, contact us so we can take appropriate action.

9. International transfers

We may process information in countries other than where you live. When we transfer personal information internationally, we take steps designed to ensure appropriate safeguards are in place as required by applicable law.

10. Retention

We retain information for as long as reasonably necessary to provide the Services, comply with legal obligations, resolve disputes, and enforce agreements. Retention periods may vary depending on the type of information and how it is used.

11. Changes

We may update this Privacy Policy from time to time. We will revise the effective date above, and for material changes we may provide additional notice (such as in-app notice or on our website).
