If something does not work

Tell us the app version (shown in Settings), your device, the operating system version and briefly what happened. Please do not send ID copies, payment details or confidential naturalisation documents.

Restoring a purchase

Tap «Restore purchase» in the app and use the same store account as for the purchase. This needs an internet connection. A purchase with Apple and a purchase with Google are separate purchases.

Changing the language

In Settings, choose under «Your language» the language the app explains in. The «Exam language» — German, French or Italian — is picked by the app from the postcode of your home town; you can change it in Settings as well.

Daily reminder

Switch on the «Daily reminder» in Settings and choose the time. Your device schedules the notification itself; nothing is sent. If no reminder appears, allow notifications for the app in your device settings.

Deleting your data

You delete progress, details and your own cards in the app settings with «Delete everything». This cannot be undone. If you remove the app from your device, its data there is removed as well. A store purchase remains and can be unlocked again with «Restore purchase».

Something is no longer correct

Tell us the card or municipality, the explanation language and — if shown — the source, so we can check the information.

Binding information

We are not an authority. Binding information about your procedure comes from your municipality, your canton and the State Secretariat for Migration.
