The first time users use Kolibree they are asked whether they want to receive notifications from the application.
These notifications are used mainly to send weekly reminders to users to synchronize their Ara toothbrushes with the application, which enables any brushings that have taken place offline (without the application) to be recorded in the application and the brushing data displayed.
You can turn off or turn on notifications at any time in your account settings (Settings > Account > Notification synchronization), as well as in your phone's settings (Settings > Notifications > Kolibree)
