Local storage
Theme, a home city, pinned world-clock cities, meeting-planner cities, timer state, and calendar events are written to local storage on this computer. A clock-skew warning can sit in session storage until the tab closes. We do not upload those lists to a server we operate.
Hosting
Each file request can log a time, a path, and a network address. Google Cloud runs that host. We do not run a database of visitors.
Weather and time
Forecasts go from this device to Open-Meteo. A one-off UTC check may go to TimeAPI.io or Cloudflare, only to warn if the machine is more than 30 seconds off.
