We answer every message, usually within two business days. It helps enormously if you say which device you are using, which screen you were on, and what happened.

How do I change the age mode?

Tap the gear on the map, then “Who is playing?” — koala for ages 4–6 (voice-guided, no reading required) or kangaroo for 7 and up, which adds written lessons, a hint button and a tactics world. It can be changed as often as you like.

My child wants to start over

Settings → “Start over”. It is protected by a grown-up question — a simple multiplication — so a child cannot erase their progress by accident.

Where is my progress stored?

Only on the device. Nothing is uploaded anywhere, so deleting the app deletes the progress and there is no account to restore it from. Progress does survive normal app updates.

A world or the club is locked

Each world opens after its boss match is won, which is by design. If your child already knows the basics, tap “I know chess basics — skip the lessons” on the first screen to open everything at once.

There is no sound

Check Settings → “Sound & voice” inside the app, then the device volume and the silent switch. Chezzo speaks with the operating system’s built-in voice, so if other apps are silent too, it is a device setting.

Does it need the internet?

No. Chezzo works fully offline and makes no network requests at all — it is completely functional in Airplane Mode.

The app looks wrong on my phone or tablet

Please write in and say which device and which screen. Layout problems on specific devices are the most common bug report and the easiest to fix.
