ClockMate (“the app”, “we”, “us”) is a two-player chess clock for iOS and Android. This Privacy Policy explains how the app handles information. In short: the app collects no personal data, shows no ads, and uses no tracking.

Information We Collect

We do not collect or receive your personal data. The app has no account system, no sign-in, and no server backend operated by us. We do not know who you are and we cannot identify you.

Information Stored on Your Device

Your preferences — clock setups, favorites, theme selection, language, and sound settings — are stored locally on your device. The app also saves the current game, series score, optional player names, and the most recent 100 completed games with move timing statistics so they can be recovered after reopening. This information is not sent to us or to a server operated by us. You can clear match history inside the app; deleting the app removes its local data, subject to any device backup and restore settings controlled by your operating system.

Results are shared only when you choose Share or Copy. Share opens your device’s sharing options with a result card and summary, including any player names you entered. Copy places the summary on your device’s clipboard. The recipient or application you choose then handles the information under its own policies.

Purchases

The app is free and unlocks all features for everyone. It offers only optional, voluntary donations (“tip jar”) to support development — there is no paid unlock, subscription, or paywall. All payments are processed entirely by the Apple App Store or Google Play. We never receive or have access to your payment details (card numbers, billing address, etc.). Purchases are handled under the stores’ own privacy policies:

Donations are one-time, consumable purchases; there is nothing to restore.

Advertising and Analytics

The app contains no advertisements, no analytics, and no third-party tracking or advertising SDKs.

Device Permissions

The app requests no special device permissions. It does not access your camera, microphone, location, contacts, photos, or personal files. Sharing a result creates a temporary result image for the sharing option you choose. The app may keep the screen awake during a game so the clock stays visible; this uses no personal data.

Children’s Privacy

The app is suitable for all ages and collects no data from anyone, including children.

Data Security

We do not receive your locally stored game data. Local settings, optional player names, and game records are protected by your device’s standard security.

Changes to This Policy

We may update this Privacy Policy from time to time. The current version is available in-app and on our website, with the “Last updated” date shown above.
