About Google’s Find Hub
From the developer's description on Google Play.
For your devices and items • View your phone, tablet, headphones, and other accessories on a map–even if they’re offline. • Play a sound to locate your lost device if it’s nearby. • If you’ve lost a device, you can remotely secure or erase it. You can also add a custom message to display on the lock screen in case someone finds your device. • Find your devices and items on Mobile and supported Wear OS devices. • All location data in the Find Hub network is encrypted. This location data is not visible even to Google.
For location sharing • Share your live location to coordinate a meetup with a friend or check on family to make sure they got home safe.
