So the dev was talking about this in Accrescent’s Matrix server. He acknowledged there being privacy concerns, and said that while there will always be some information that could be gathered even implicitly when downloading split apks, he said that he’s looking into ways to make fingerprinting more difficult. He gave the example of having the client check for app updates irregularly for different apps, so it would be less apparent that it’s the same client requesting the update and this would be harder to profile based on installed apps. He also said that practically speaking, the device identifiers were typically the same across the same device+OS combo, so even if there are a lot of identifiers they don’t necessarily make a unique fingerprint all of themselves.
Keep in mind I’m paraphrasing greatly and that’s just what I understood of it all haha.
