The byline says "High-precision" but I could not find any benchmarks or scientific analysis. What does high precision mean here? How stable is it? What about p

  Yep. Needs to answer what is the precision?

  The actual precision you get depends on context, as this system utilizes surrounding signals (Bluetooth/WiFi/etc.) in the given environment to classify the location. Generally rooms/walkways are easily distinguishable. Pieces of rooms are also usually distinguishable because of smart devices people generally acquire nowadays (e.g. a Google home at one side of the kitchen is sufficient). I say high-precision because I compare it to GPS, but if you compare it to round-trip time (RTT) measurements which get cm-level precision from specialized hardware, it is an order-of-magnitude behind. The public server knows the mac addresses of devices that they send to it, so in a sense it does know where they are (because those can be reversed with public wardriving databases). The public server does not have authentication, so if someone figures out your "family name" then they can see your data. I suggest using the public server to try FIND, but not to use FIND so I have instructions for setting up your own system. [1] I'll make this more clear in the docs.
