What is 26?
26 is a mobile learning app for discovering Switzerland canton by canton through maps, quizzes, collections, and challenges.
Which languages are available?
The app and website support French, Swiss German, Italian, Romansh, and English. You can change the language in the app settings or with the language menu on this website.
Does the app work offline?
An internet connection is required to download content on first launch. Core installed learning content and local progress can then work on the device, while accounts, synchronization, daily challenges, friends, leaderboards, and notifications depend on online services.
Do I need an account?
Yes — playing 26 requires a free account. After the first sign-in, installed content and locally cached progress remain available offline; synchronization and online features resume when the connection returns.
How do I delete my account?
Open the account screen in the app and choose “Delete account”. The confirmation flow explains that account and server data deletion is final. If you no longer have access to the app (lost device, app uninstalled), you can also request deletion of your account by email to support.
How do I change notifications?
Use the notification settings in 26 to choose categories, and your device settings to allow or block notifications for the app.
How do I restore an ad-free purchase?
Open the profile screen and choose “Restore purchases” while signed in to the store account used for the purchase. TestFlight sandbox purchases do not become App Store production purchases.
