This Privacy Policy describes how Vinh Tran ("we", "us", or "our") manages user information for the 1s Math mobile application.
By downloading, installing, or using 1s Math, you agree to the terms outlined in this policy.
1s Math is designed with user privacy in mind:
No Personal Data Collected: The application does not collect, track, or share any personally identifiable information (such as your name, address, phone number, email address, or device identifier).
Local Storage Only: Game progression data, including your highest score (High Score) and sound preferences (Mute/Unmute), is stored exclusively on your device locally via offline storage. This data is never sent to or stored on any external servers.
The app only requests standard permissions strictly required for basic functionality (such as device vibration for haptic feedback upon Game Over). It does not access your location, camera, microphone, contacts, or storage files.
The application does not integrate with any third-party SDKs, analytics platforms (such as Firebase Analytics), or advertising networks that collect or process user data.
1s Math does not address anyone under the age of 13, nor does it knowingly collect any personally identifiable information from children under 13. Since the app does not collect personal data from any user, no children's data is stored or processed.
We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date.
If you have any questions, feedback, or concerns regarding this Privacy Policy or the practices of 1s Math, please contact us at:
