Birthdays app analytics for December 25

I developed this app to be more independent from other services. I realized that I do not want to forget my roommate's birthday just because he deleted his account in a certain social network, which would otherwise have indicated his birthday. Furthermore I wanted a simple service, no integrated calendar services that for the most part have additional features I do not use. And I wanted a service that by no means passes on data to third parties or transfers data over the Internet. This app is really simple and does not have the possibility to access the Internet. Everything is stored on your smartphone. The app needs the permission "set alarm" and "execute after boot completed" to create correct notifications. The app needs the permission "change or delete external storage" and "read external storage" to import or export data when you want it. The app will never do this automatically. No responsibility will be accepted if the app displays notifications incorrectly or not. This app is being developed by Sebastian Oltmanns.
