Thanks. This is very basic, so if you decide to use it, you may want to
improve/tweak it. At least you need to decide how you manage coupons:
by device (how do you identify devices?), user (google account, email),
etc.
I haven't yet installed anything of that but one way would be to have

I don't think those issues are really that relevant. For my situation at

This is only to give out some free copies to some persons, not to use as a

trying to understand how secure is SharedPreferences and what alternatives
are there, that's all.
On a rooted device SharedPreferences absolutely can be tampered with.
Same with any on-device storage. However this doesn't mean you can't

If what you want is to be able to give out free copies to some users,
implement another unlocker, that is similar to the paid premium unlocker
you're planning for Market, but is free.
