Privacy you can read.

Our full privacy policy is in final review. No history. Ever. We keep where you are now, never where you’ve been. While Always On is in place, your phone reports where you are as you move. We keep only the latest point and delete it after 24 hours. There is no trail. A point you send in answer to a nudge stays on their map for 30 days. We never sell any of it. The policy will explain exactly what we keep, for how long, and why.

Full policy publishing before launch.
