Privacy Policy

Last updated: October 13, 2026

CoinEcho: Physics Puzzle ("we", "our", or "us") respects the privacy of our players. This Privacy Policy explains what information CoinEcho collects, how that information is used, and the measures we take to protect it.

By downloading, accessing, or using CoinEcho (the "Game" or "Service"), you acknowledge the practices described in this Privacy Policy.

1. No Data Collected

CoinEcho does not collect any personal or non-personal information. There are no accounts, no registration, and no login. We never gather data that could identify you or your device, including names, email addresses, contacts, location, or device identifiers.

2. No Ads and No Trackers

The Game contains no advertisements. There are no ad networks, no analytics SDKs, no third-party trackers, and no advertising identifiers used anywhere in the Game.

3. Progress and Echoes Stay On Your Device

All game progress, saved trajectories, and recorded echoes are stored locally on your device. Puzzle state never leaves your device, and removing the Game deletes that data.

4. Offline Play

CoinEcho works completely offline. Your gameplay is never transmitted to any server or third party, and the Game does not require a network connection to play.

5. Permissions

The Game requests no sensitive device permissions. It does not access your camera, microphone, contacts, photos, or location.

6. Third-Party Services

The Game includes no third-party analytics, advertising, or data-sharing services. The only third party involved is the app marketplace (Apple App Store) that distributes the Game. We encourage you to review the privacy practices of your app marketplace if you have questions about platform-level data handling.

7. Children's Privacy

CoinEcho is rated 4+ and is suitable for all ages. Because we collect no information of any kind, there is nothing to share or disclose, including information from children.

8. Data Security

Because no data is transmitted or stored on our servers, there is no database for us to protect. Your progress is safeguarded by the standard security of your device's operating system.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes take effect when the revised policy is posted here. We recommend reviewing this page periodically.
