Privacy Policy

Last Updated: May 27, 2026

Welcome to Block Stroke (the "App"). This Privacy Policy explains how we collect, use, and protect information when children use our App. We are committed to protecting the privacy of children and complying with applicable laws, including the U.S. Childrens Online Privacy Protection Act ("COPPA"). Please read this policy carefully.

1. Information We Collect

We take extra care in collecting information from children under the age of 13.

• No Personal Information: We do not knowingly collect, store, or share any personally identifiable information (such as names, email addresses, phone numbers, or precise location data) from children under 13 without verifiable parental consent.

• Usage Data & Analytics: We may collect non-personally identifiable information, such as app usage statistics, device type, and general interaction data, solely to improve the App's performance and user experience.

2. How We Use Your Child's Information

Any non-personal information collected is used exclusively for the following purposes:

• Operating and maintaining the core functionality of the App.

• Analyzing app performance to fix bugs and improve content.

• Ensuring compliance with legal obligations and child safety standards.

3. Sharing of Information

We do not sell, rent, or trade any information collected through this App. We only share non-personal analytics data with trusted third-party service providers who assist us in operating the App and are bound by strict confidentiality agreements. We will never disclose personal information to third parties for behavioral advertising or marketing purposes.

4. Parental Rights and Consent

Under COPPA and similar regulations, parents have specific rights regarding their child's information:

• Parents can review the personal information collected about their child (if any).

• Parents can request the deletion of their child's information.

• Parents can refuse further collection or use of their child's information.

• If you wish to exercise these rights or provide verifiable parental consent, please contact us at lubaobao2020@icloud.com. We will respond to verified requests within a reasonable timeframe.

5. Data Security

We implement robust technical and organizational security measures designed to protect children's information from unauthorized access, alteration, or disclosure. However, no electronic transmission over the internet is completely secure.

6. Changes to This Policy

We may update this Privacy Policy periodically to reflect changes in our practices or legal requirements. We will notify users of significant changes by updating the "Last Updated" date and posting an in-app notice.
