Getting help

Email iasnezhkov@gmail.com. Include your device, OS version and the app version from Settings — most questions can then be answered in one reply.

Reporting a wrong answer

This is the report that matters most, and it is easy to make a good one: every question in Gokaku shows the official rule it comes from and the exact chapter reference. Quote the question and that reference. Either you will get back the passage that decides it, or the question gets fixed — a wrong question is worse than a missing one.

Progress, backup and reset

Gokaku stores everything on your device and has no accounts, so there is nothing to recover from a server if you lose your phone.

• Move to a new device: Settings → export progress, which writes a gokaku-progress.json file you can send to yourself, then import it on the new device.
• Start over: Settings → Reset progress.

Tips and refunds

Tips are voluntary and unlock nothing. Refunds are handled by the store, not by the developer — use reportaproblem.apple.com on iOS, or Google Play support on Android.

Privacy

Gokaku works offline and collects nothing. See the privacy policy and the terms of use.
