In general, yes! We did some follow on work explaining how all of this works, depending on the provider: https://petsymposium.org/popets/2026/popets-2026-0113.p

- ollien 2mo agoVery cool! I only skimmed Section 4 a bit, but that's really cool! 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 :)
