XDays

This app is free and open source. It doesn't collect any data.
The only permission that is needed is to show notification (if you want a notification for an event)

It is a simple day counter app.
Any date you add, it will show the days remaining or days completed since the date.
You can set a future date and add a notification (which is optional).
You can set a counter from past date. The app will show how many days are remaining and notify you once the day arrives.
Only Add and Delete functionality present.
