Calendar Checker

Your Google calendars, together on your device.

Privacy first. 100% free. No subscriptions. No hidden costs. Bring your Google calendars together in Chrome. See what is next, make plans and get on with your day. • Connect multiple Google accounts and choose the calendars you want to see. • Plan your week or explore the month in a clear, compact calendar. • Check your next event at a glance on the Chrome toolbar. • Create and edit events, invite guests, add Google Meet and set up repeating plans. • Choose desktop reminders, custom notification sounds and snooze times. Set quiet hours when you want to focus. • See two time zones side by side. • Keep already saved events available offline; changes wait until they can be sent to Google. • Choose light or dark mode, calendar colors and the layout that suits you. Your day is personal. It should stay that way. Calendar Checker saves its calendar copy, preferences and notification sounds on your computer. It has no application backend, ads, analytics or tracking. The developer does not receive your calendar data. Sign-in and calendar updates go directly to Google, only for the accounts you choose to connect. Your original events stay in Google Calendar. Want fewer sensitive notes saved offline? Turn on Exclude event descriptions in Settings. Previously downloaded descriptions are removed too; descriptions you write in unsent changes remain until Google saves your work. All features are free. There is no subscription, paid upgrade or hidden payment. Calendar Checker is open source under GPL-3.0. Chrome needs to be running for reminders. Sleep, quiet hours and your computer’s notification settings can delay or silence alerts.
