What to include

These details let us solve things far faster.

Your device

Model and OS version — for example, Galaxy S24 on Android 15, or iPhone 15 on iOS 18.

What happened

Which screen you were on and what you did just before the problem. A screenshot or screen recording is ideal.

For purchases

The date and time, the product name, and the order number from your store receipt.

FAQ

Common questions

My save data is gone

Game data is stored on your device by default. Uninstalling the app or resetting the device removes it, and in that case recovery may not be possible. Email us with the details and we will help as far as we can.

How do refunds work?

In-app purchases are processed by Google Play or the App Store, so refunds follow each store’s policy and process. If the store cannot help, email us with your order number and we will look into it.

I watched an ad but got no reward

Occasionally the completion signal does not reach the game because of a network issue. Try again on Wi-Fi, and if it keeps happening tell us roughly when it occurred and which screen you were on.

I want to access or delete my data

Email us and we will handle it without undue delay. Full details are in the Tank Heroes and Tower Hero privacy policies.
