I was going to ask how the web UIs possibly work if the location is indistinguishable, but I went to the Google Find Hub, and it appears you can't view the location for tags unless you enter your phone's pin code / pattern lock. This must either communicate with the phone or the keys are stored on Google's end.
EDIT: I turned my phone off, and I can still get the location of my keys... surely this doesn't mean the key is stored on their end? Wouldn't be very good E2EE in that case :)
> Providerslike Apple and Google achieve location indistinguishability by end-to-end encrypting location information using a public key embedded in BLE advertisements emitted by a tag
Though it makes me wonder... What's the private key? If the public key is attached to the tag, how is the device getting it? I'm guessing it gets shared during pairing.

This seems to scratch that itch. The non determinism makes it probably not suitable for most uses, though.
Hope things are going well with you at Dagger(?)!
