Sound familiar?
ClearCal turns calendar noise into a clear signal.
How it classifies
ClearCal uses simple calendar signals to colour-code your week, so you can spot the type of meeting without opening every event.
Customer calls, vendor reviews, partner meetings, and anything with someone outside your organisation. These are the meetings you usually need to prep for.
Tomato redJust you and one other person. The focused conversations that are easy to miss but often matter most.
Basil greenTeam syncs, standups, all-hands, and internal meetings with three or more people from your organisation.
Peacock blue FreeFocus time, deep work, reminders, and holds you set for yourself.
Banana yellow ProAnything on Saturday or Sunday, highlighted clearly so it does not sneak up on you.
Graphite grey ProEvery colour is fully customisable on Pro. Pick from all 11 Google Calendar colours per rule. Toggle rules on or off, and changes apply instantly.

How it works
Add ClearCal from the Chrome Web Store, then connect Google Calendar using Google sign-in.
ClearCal checks your upcoming meetings and works out what type of event each one is.
Meeting colours are written directly to Google Calendar, so they show up wherever you view your calendar.
New and updated events are refreshed automatically, so your calendar stays readable.
Privacy & Security
Most productivity tools work by syncing your data to their servers. ClearCal is built differently. Calendar classification runs in the Chrome extension, so your calendar data never has to leave your device.
Classification runs entirely inside the Chrome extension. Events go from Google's API to your browser. ClearCal's server never sees them.
You sign in through Google's own screens. ClearCal never sees your password. Your access token is stored only in your browser's local storage, never on a server.
Brokers your Google sign-in and validates your licence. That's it. No calendar access, no event records, nothing else.
No analytics, no tracking scripts, no event metadata. We don't know which meetings you have or who you meet with.
Read events and update their colour. That's the full extent of ClearCal's access. It cannot create, delete, or share events, and has no access to Gmail, Contacts, or Drive.
Disconnect from the popup at any time. Access is revoked instantly and all local tokens deleted. Or go straight to your Google Account permissions to remove it from there.
Works everywhere
ClearCal writes colours directly to your Google Calendar events via the API, not as a visual overlay. Once set, the colours live on the event itself and show up on every device and app that connects to your Google Calendar.
The colour lives on the event, not in the extension. ClearCal just needs to run once.
Start with a 7-day Pro trial of every feature, then keep Free or upgrade when your calendar needs more signal.
