TimeRail — Track Your Calendar Events On The Timeline

A minimal timeline bar showing your day and calendar events.

TimeRail is a Chrome extension that shows your day as a thin timeline bar at the top of every page, with today’s Google Calendar events plotted directly on the timeline. It is built for people who want to stay aware of their schedule while browsing, without opening a new tab, dashboard, calendar view, or time-tracking app. The bar stays quiet by default, expands on hover, and gives you a quick visual sense of where you are in the day. KEY FEATURES • Daily timeline bar — see progress from your chosen start hour to your chosen end hour • Google Calendar event ticks — hover over an event marker to see its title and time • Read-only calendar access — TimeRail never creates, edits, or deletes calendar events • Automatic refresh — events update every 5 minutes, with manual refresh available in the popup • Hover-to-expand design — the timeline stays out of the way until you need more detail • Custom settings — choose the fill color, time range, reveal delay, and visible sites • Site visibility controls — show TimeRail everywhere, hide it on selected domains, or allow it only on specific domains • Optional private display — hide event titles and show event times only PRIVACY TimeRail does not collect, transmit, sell, or share personal data. Calendar data is fetched directly from the Google Calendar API using your own OAuth token and cached locally in Chrome storage for up to 5 minutes. It never goes to a TimeRail server. TimeRail does not have a backend server. TimeRail uses read-only Google Calendar access only to display today’s timed events on the timeline.
