Can I know when the user delete my app?

Question

I'm wondering to know if I can have a event or some way to know when the user deletes my App, so I can delete him from my Database. Is it possible?

First; Just because the user deleted the app on one device doesn't mean they don't have it installed on others - or won't install it on others.

To your question; Apple doesn't give you a way to do this. Perhaps you could use some sort of "expiration" window - e.g.: if they don't start the app within 90 days, expire the records from your database?
