Copybook ("the app") is an offline Android game of dots and boxes, published by The Basement Coders. This policy explains what data the app does and does not handle.
Summary
- No account is required. Copybook has no login and does not ask for your name, email, or any personal identifier.
- Your games stay on your device. Settings, scores and the head-to-head record between two players on one phone are stored locally and are never uploaded to us.
- No analytics or tracking SDKs are included by the developer.
- The game itself works fully offline. There is no multiplayer server, no matchmaking and no sync.
Data the app stores on your device
The following are stored locally only and are never transmitted to the developer:
- App settings — paper, pens, claim marks, board size, difficulty, opponent, sound, vibration and language.
- Any player names or initials you type in. These are labels for the two seats in a pass-and-play game; they are shown in the margin of the board and nowhere else.
- Your best winning margin against the computer, per board size and difficulty, and the win/loss tally between two players on this phone.
You can erase all of this at any time by clearing scores in the app's settings, by clearing the app's storage, or by uninstalling the app.
Network access
The app declares the internet permission for advertising only (see below). Playing a game — against the computer or against another person on the same phone — needs no network at all, and nothing about a match is ever sent anywhere.
Advertising
This section applies only if and when ads are enabled in a released version. They are not enabled in the current release.
If the app displays ads, it uses Google AdMob. AdMob may collect and use certain data (such as device and advertising identifiers) to serve and measure ads, as described in Google's Privacy Policy. Where required, the app presents a consent prompt (Google User Messaging Platform) so you can control personalized advertising. Ads, if present, are shown between games rather than during one, and never immediately after you have won.
A single optional in-app purchase removes ads permanently. It unlocks no content: every board size, difficulty and appearance option is free from the first launch either way.
Donations
The app links to a PayPal page where you can voluntarily support development. Following that link takes you out of the app and into PayPal, whose own privacy policy then applies. A donation is not a purchase — it buys nothing in the app and changes nothing about it.
Children's privacy
Copybook does not knowingly collect personal information from anyone, including children.
Changes to this policy
If this policy changes, the updated version will be posted here with a new "last updated" date.
