The collector fetches paid-up trackers' encrypted reports from Apple every 20 minutes on the collector Mac. "Silent" means a paid-up tracker no phone has reported for 24 hours: a flat battery, out of range of iPhones, or not fitted yet. Reports are kept 7 days, so a longer silence shows as "7+ days".

"Last heard" is when a phone last reported the tracker -- never where. Locations can only be decrypted on the client's own device.

Counts each time a page is opened: a reload counts again, so this is views, not people. Nothing about the visitor is kept: no cookie, IP address or account. Browsers that send Global Privacy Control or Do Not Track aren't counted, and neither is this computer while testing. Days are South African days.

Every change to trackers and logins, from this page or straight from the Supabase dashboard ("Dashboard or server key"), plus invite and reset links and disabled logins. Nobody can edit or delete these entries, not even with the secret key.
