Check in
Bootblack & Social Night · 9:30 PM
Within 150 m of the venue, your phone checks you in. Open until 1:30 AM.
Demo: you aren't in Seattle, so feed the same check a pretend position.
What your phone sends
Only when you're inside the area, and only this:
{"ticketId":"tk-001","inside":true}No latitude, no longitude, no accuracy, no distance. Those stay on this phone. To check, the phone first asks Colors for the venue's area; that request carries your ticket, not your location, and the area isn't saved.
What we store
Nothing yet. After check-in: the time, and that you checked in by location. Never where you were.
6FNS-WE83-92NY-C36N-0RPSTreat this like a key. Anyone holding this code can use your ticket once.
Or show this to the door volunteer.
Your phone works out whether you're near the venue. Colors never receives your location, so there's no location history to leak, subpoena or sell.
