How to share your location for a short time
Quick answer
To share your location temporarily, use a time-limited link in Google Maps or Find My, which expires after the window you set. For ongoing closeness, a local proximity ping avoids sharing at all.
Both Google Maps and Apple's Find My let you share live location for a set window, an hour or a day, then stop on their own. That covers meetups and rides home. For staying close to friends over the long run, though, repeated sharing feels heavy. A lighter option keeps a private list of where friends live and pings you locally when you are near, so you skip the share-and-revoke loop entirely.
In one sentence
Parages pings you when you pass near a friend. It tracks nobody.
