For context: I recently switched to a Pixel 9, installed GrapheneOS and created a profile just for some apps I need Play Store for, which is sandboxed btw. I created a new empty google account for it too.

So I was just downloading an app and saw the option to download it on my old device too, which made me wonder how GP knows about it, since I don’t think I have anything on my new phone that could link to it (except my SIM I guess)

Any ideas?

    possibly:

    • SIM (subscriber identity module)
    • current location
    • same wifi SSID
    • your old phone was at some point simultaneously on and got detected through some nearby share discovery

    etc.

      I’m guessing same wifi SSID would be the most plausible? Since it is the only thing my sandboxed GP really has access to. Didn’t think of it, thanks!
