Ho trovato questa: una sandbox per isolare un'app e impedire che faccia cose strane (tipo accedere ai contatti).

What is "Island"

"Island" is a sandbox environment to clone selected apps and isolate them from accessing your personal data outside the sandbox (including call logs, contacts, photos and etc) even if related permissions are granted. Device-bound data is still accessible (SMS, IMEI and etc).
Isolated app can be frozen on demand, with launcher icon vanish and its background behaviors completely blocked.
