My son’s phone is the most unsecure of the three, mostly because of lots of games. He’s good with just about anything fun, with a couple exceptions that he had to have. Since the phone will last three more years of security updates, I wanted him to understand the reasons behind the app choices I made, so he can make informed choices when he’s the one making the decisions on what apps to use. Here’s the documentation of the rules (and exceptions) I held myself to to keep tracking to a minimum, enjoy:
Trackers
Apps with many trackers, or that have the “run at startup” or “modify or delete the contents of your shared storage” permission, must not be installed at all.
Exception #1 Whatsapp (under Shelter)
Apps with any “ad” trackers, such as Google AdMob, Unity3D Ads, or Facebook Ads, must not be installed at all.
Exception #1 Google Play Store (not signed in under main account. Only signed in under Shelter)
Apps with any trackers must be installed under Shelter, and frozen when not in use.
Exception #1 μ?acra is a “good” tracker used by Newpipe.
Exception #2 Proton VPN (and Among Us) seem to use 2?Sentry.
Exception #3 Android apps Calculator, Messages, Phone, and Photos all use Google Firebase Analytics.
Apps that try to connect to Google Play must be installed under Shelter and frozen when not in use, including apps that require Billing service permission.
