Deep Time collects nothing

Last changed: 14 November 2026

The app

Deep Time does not collect, store or share any personal data.
The app makes no network connections. Everything it shows is contained in the app or calculated on your Mac.
There is no account, no sign-in, no advertising and no analytics.
The app does not use Location Services. You choose a place from a list of cities inside the app; the first time, it suggests the largest city of your Mac's time zone.
The app remembers one setting, the place you chose, on your Mac. It never leaves your Mac.

Like every web server, the one behind this site keeps a short log of requests (address, time, page) to run the site and to fend off abuse.
