Playing and saving

Game progress is saved locally on your device. Keep your device backed up if you want to preserve it. Resetting, removing the app or losing the device may remove progress. A daily puzzle uses your device’s current local date. Stars and levels represent local game achievements and have no monetary value.

Advertising and reminders

Advertising is supplied by Google AdMob and availability varies with connection, privacy choices, inventory and service status. Interactions with an advertised service are subject to that service’s own terms. Optional reminders depend on notification permission, Focus settings and iOS delivery. You can turn them off at any time.

Artwork and software

The apps and original artwork belong to Sebastian Mraz. You may use the apps according to Apple’s standard licensed application agreement. Do not misuse the software, advertising or another person’s rights.

Availability and your rights

We aim to keep the games useful but cannot guarantee that the software or third-party services will always be available or suitable for every purpose. Nothing here limits mandatory consumer rights or liability that cannot legally be excluded. Any future changes to access, pricing or these terms will be communicated clearly.
