How can we help?

Email [email protected]. Include your device, app version and a short description of the problem. Do not send passwords, payment details or private conversation transcripts.

Purchases and access

Use Restore purchases on the Premium screen while signed into the store account that purchased the subscription. You can manage or cancel renewals in your Apple or Google subscription settings.

Speech and learning

Allow microphone access for pronunciation practice. Speech recognition needs the Czech speech model downloaded to your device. When a word cannot be recognised, you can continue with listening and manual flashcards.
