Tile is a tracking protocol with a track record, so at least it’s not a one-off. If you turn on “find by community” then Tile will have lots of data on the location of this keychain (and presumably, the people carrying it). If this particular implementation of that protocol is safe, I don’t know.
The Tile protocol is basically a device screaming “I’m unit #12345” into the Bluetooth void. It can also beep when requested. That’s about it. If you want that, buy this device.
