Best way to install sandboxed gapps only for selected apps - SLRPNK

Hi! What would be the best way to limit play serbices to only selected apps. I still need notifications to work from them, but would like to be sure that google can’t access anything else

AFAIK, the only way to limit certain apps using GPS is to install in another profile.

grapheneos.org/usage#sandboxed-google-play will give you the complete rundown on how this works.

That is a great rundown, thanks! How would I install them on a different custom rom? Upon installing their “apps” store, i can’t see the google play services (this might be because I’m currently on stock)
Sandbox Google Play is just for GrapheneOS. As far as I know, doesn’t work anywhere else.
