We are here to help you hold the line.

COPU works locally, so your campaign is playable without an account — but progress that lives only on a device is lost with that device. Open Account & wallet and link a Google or Apple account. From then on your progress, COPUCOIN, and boosts are stored in the cloud and follow you to a new phone.

That happens when the device already has local progress and the account already has a cloud save. COPU never merges two saves, because a merge quietly invents progress that neither save had. Pick the one you want to continue — we keep a backup of the one that is replaced, so if you choose wrong, write to us and we will look.

In COPU, open Account & wallet → Danger zone → Delete account & progress. If you cannot access the app, use the instructions on our Account Deletion page. Deletion is permanent, and it takes your COPUCOIN balance with it.

First make sure you are signed in to the same account you bought on — coins are credited to an account, not to a device. If they are still missing, email us with the Google Play or App Store order reference and we will sort it out. We never need your password, card details, or a one-time code.

Purchases are taken by Google Play or the App Store, and their refund policies are usually the fastest route. Your statutory consumer rights apply in full — see Right of withdrawal and If something is wrong in our Terms of Use. If a purchase did not work, contact us and we will fix it regardless.

No. COPU contains no ads, no advertising SDK, no cross-app tracking, no chat, and no player-created content. The only optional spending is COPUCOIN, and the campaign is designed to be finished without it.

Two things, both switchable in the game's Settings. Crash reports are on by default and describe the app when it breaks — the failing code, your device model, the level you were on. If Play data is also enabled, recent Analytics events can appear as breadcrumbs in a crash report. Play data is off until you agree on first launch; if you do, it sends which level, which attempt, and whether you won or lost, plus basic app-session and device details, so we can find levels and flows that need work. It can also include store and cloud-sync outcomes. Neither carries your name, your email, your moves on the board, or an advertising identifier. Play-data collection stops immediately when switched off. On iOS, the native Crashlytics opt-out completes after you close and reopen COPU. The full detail is in the Privacy Policy.

Yes. Please include your device model, operating-system version, the COPU version, and the steps that led to the issue. This helps us reproduce it without asking for more personal information than needed.
