java - In-App Billing V3 - Purchase an Object that expires after 3 months - Android -

i must implement in android app purchase of item expires after 3 months.

i read on developer guide should utilize "unmanaged" products, read in v3 version of api object handle managed product.

the question following, after users purchase unmanaged object how can manage expiration? illustration when period expire, user can purchase time same product if want?

are using online database app?

if true, think best way generating end date when item purchased , saving in online database. have check if end date not past regularly in app (for illustration every time user start app,...).

this works me, in case app connects regularly online database work.

other methods, save end date in local storage can easy hacked.
