A private map of your travels. No account to make, no server to trust, and every feature works with no signal.
Pinned turns what you already have into a map: your camera roll, a list you wrote in Notes, or the trips your phone quietly noticed. And you can always just tap the map. Nothing is uploaded to make any of it work.
There is no setup screen to get through, because there is nothing to set up. Open it, bring in what you have, and mark places as you go.
Not a policy you have to take on trust. There is no account layer and no server, so there is nowhere for any of it to go.
