01 General Audience, No Age Restrictions & Content Safety

This educational tool is designed to be completely safe for users of all ages ('Everyone'). There are absolutely no age restrictions.

The application contains no violence, no inappropriate material, and no user-to-user communication features. Because zero personal data is collected or transmitted, this app operates in full compliance with global children's privacy regulations (including COPPA).
