Question

I want to save some info regarding a trial version an application.

I want this info to be persistent in order to detect if the user removed the application and installed it again after the trial expiry.

what is the best place to store such info

Answer 1

Most of the times the solution to this problem is to keep an server side check,

But if you dont want to involve a server its better to give some limited functionality in your trail app and full in the paid version.

There are other methods too like Time Trial but again they all depends on persistent data so they also fails if the user uninstalls and installs again your applucation
