Children's Privacy

One Stroke is a puzzle game intended for a general audience. It does not knowingly collect any personally identifiable information from children under the age of 13 (or the applicable age of digital consent in their country).

Since we do not collect personal data from any users, we inherently comply with COPPA (Children's Online Privacy Protection Act) and similar regulations.

Advertisements displayed in the app are served by Google AdMob. For family-specific settings and controls on ad targeting for children, please refer to Google's Family Policy resources.

Third-Party Services

The App integrates the following third-party services. Each operates under its own privacy policy:

Service Provider Purpose Privacy Policy
Google AdMob Google LLC Ad serving & monetization View Policy
Google Play Services Google LLC App distribution & updates View Policy

CS Boiii is not responsible for the privacy practices of these third-party services. We encourage you to review their individual privacy policies.

Data Security

Since One Stroke does not collect or transmit personal data to any server operated by us, the risk of a data breach from our end is eliminated by design.

All game data (progress, settings, streaks) is stored exclusively on your local device and protected by your device's own security mechanisms (screen lock, encryption, etc.).

🛡️
Zero-server architecture: There is no CS Boiii server that stores your data. No server breach can ever expose your information to us, because we never receive it in the first place.
