A stupid question, probably

Dizzycuss

Hi guys,

I can’t really understand on my own so I need a bit of help:
AFAIK apps can intercommunicate. Does that mean that Google can still send data back if I install Google Play services and Google camera even though I revoke network access for the camera?

I can’t find and answer I understand and I’m always worried that I’ll do something that’ll negate the privacy I’m trying to achieve.

Dizzycuss You shouldn't give apps access to data that you don't trust them to have. In practice, Google Camera only uses the network to fetch feature flags and report usage stats when enabled. If you don't trust Google Camera and think that's it's actively malicious to the point that it uploads your photos to their servers, you probably shouldn't be using it. That's not a very realistic concern though. Network permission toggle is not a data exfiltration toggle. It prevents network access, not all possible ways an app could come up with to exfiltrate data like playing audio, cooperating with other apps within the same profile or including it hidden within stored data.

unwat That's incorrect. There's no limit on the size of data that can be shared via IPC. Limits on the size of data transferred via intents is not particularly relevant. Sharing files is done by sharing a handle for the file via an intent and permitting the other app to access it, not transferring it directly in the intent.

Inaccurate information about interprocess communication has been removed to avoid it being propagated further.
