Common questions

My streak or progress is missing

Training progress is stored on your device. It can be lost if the app is deleted or its data is cleared. Tell us your username and what is missing, and we will look into it.

A problem or solution looks wrong

Please send us the problem as shown, your answer and the answer Calqo expected. A screenshot is ideal.

Questions about Premium or a purchase

Purchases are handled by the App Store or Google Play. You manage or cancel a subscription in your store account. For anything else, write to us.

How do I delete my account?
