How share links work

The link is the key

A share link contains a secret made of 32 random bytes from a cryptographic random number generator, far too many to guess. Anyone holding the link can see that trip without signing in, so treat it like a password: send it only to the people you want following along.

What a viewer sees

The trip's route so far, including when you passed each point (and so where you stopped), and your last known position, refreshed every 30 seconds while the trip is live. Alongside the map: the trip name, its start and end times, distance, climb and descent, and top speed. If you turn on waypoints for a trip, its waypoints and their notes are shared too.

When the link is pasted into a chat app, its preview shows the trip name, distance, climb and a picture of the route. The page never shows who you are, and each trip has its own link, so sharing one trip reveals nothing about your others. Viewers need no account and install nothing.

Revoke or regenerate at any time

A link does not expire on its own. Revoking it, or regenerating it for a new one, takes effect immediately: anyone still holding the old link sees "link no longer valid". Deleting your account removes all of its share links at once.

Kept out of search engines

Every share page is sent with a header telling search engines not to index it or follow its links. When a viewer clicks a link out of a share page, their browser does not pass the share link on to that site.

How long trips are kept

How long trips are kept, how to export them, and how to delete everything are set out in the privacy policy.
