Privacy Policy

1. Scope and Controller Information

This Privacy Policy applies to all mobile applications, websites, and related services published under Yangmin Developer on Google Play (collectively, the "Services"). Yangmin Developer is the controller for personal information processed through the Services unless otherwise stated in a specific app notice.

This policy explains what information we process, why we process it, how long we retain it, and what choices you have. By using the Services, you acknowledge this policy.

2. Information We Collect

We only collect information that is reasonably necessary to provide and improve the Services. Depending on the app and device settings, we may collect:

• Usage and diagnostics data: crash logs, performance metrics, app events, and error reports.
• Device and technical data: OS version, device model, language, timezone, app version, and identifiers.
• Content you create locally: files, scans, and exported documents processed by app features.
• Support communications: information you provide when contacting us (for example, email content).
• Advertising and attribution data: where ads are shown, ad-related identifiers and engagement events.

We do not intentionally collect sensitive personal information unless you voluntarily submit it through support channels.

3. How We Use Information

We process information for the following purposes:

• To provide core app functionality, including scanning, exporting, and sharing features.
• To maintain security, detect abuse, and prevent fraud or unauthorized activity.
• To measure reliability, fix bugs, and improve app quality and usability.
• To communicate service notices, legal notices, and support responses.
• To comply with applicable laws, regulations, and lawful requests.

4. Legal Bases (Where Applicable)

If regional laws such as GDPR apply, we rely on one or more legal bases to process data:

• Contract: processing required to provide requested app features.
• Legitimate interests: security, diagnostics, and service improvement.
• Consent: where consent is required (for example, certain advertising technologies).
• Legal obligation: compliance with legal and regulatory duties.

5. Data Sharing and Recipients

We do not sell personal information. We may share limited data with service providers and partners when necessary to operate the Services, including:

• Cloud infrastructure, analytics, crash reporting, and security vendors.
• Advertising and attribution partners, subject to your settings and applicable law.
• Professional advisers, regulators, or authorities where legally required.

Third parties process data under their own terms and privacy notices. We encourage users to review third-party policies where relevant.

6. International Transfers

Your information may be processed in countries other than your own. Where required by law, we implement appropriate safeguards for cross-border transfers, such as contractual protections and security controls.

7. Data Retention

We retain information only for as long as necessary for the purposes described in this policy, including legal, accounting, or dispute-resolution obligations. Retention periods may vary by data type:

• Operational and diagnostic logs are retained for limited periods.
• Support communications may be retained for customer service and legal follow-up.
• Locally created files remain on your device unless you delete them.

8. Data Security Measures

We implement reasonable administrative, technical, and organizational safeguards, such as encrypted transmission, access controls, and environment hardening. No system is 100% secure, but we continuously monitor and improve our safeguards.

9. Your Privacy Rights

Depending on your jurisdiction, you may have rights to:

• Request access to personal information we hold about you.
• Request correction, deletion, or restriction of processing.
• Object to certain processing activities.
• Request portability of data where applicable.
• Withdraw consent where processing is based on consent.

You may also manage permissions from your device settings (for example, camera or storage access) and control advertising preferences through platform-level settings.

10. Children's Privacy

Our Services are not directed to children under the age threshold defined by applicable law unless explicitly stated in the app listing. If we learn that we collected children's data in violation of law, we will take reasonable steps to delete it.

11. Policy Updates

We may update this Privacy Policy from time to time. Material updates may be announced within the app or through store listing updates. Your continued use of the Services after an update means you accept the revised policy, to the extent permitted by law.
