About ClearCal

Your calendar is full of noise. ClearCal cuts through it. Most professionals spend 20–30 hours a week in meetings. But your calendar treats every single one the same — a wall of identical blue blocks. You can't tell a client call from a team standup, a 1:1 from a focus block, without clicking into each one individually. ClearCal fixes that instantly. HOW IT WORKS ClearCal runs silently in the background. Once you connect your Google Calendar, it scans your events and applies colours based on who's in each meeting: 🔴 External meetings — anyone outside your organisation 🟢 1:1 meetings — just you and one other person 🔵 Internal group calls — 3 or more people, all from your domain 🟡 Calendar blocks — events with no other attendees (focus time, personal holds) ⚫ Weekend meetings — anything on Saturday or Sunday Colours refresh automatically every 30 minutes and every time you open Google Calendar. WORKS EVERYWHERE — NOT JUST IN CHROME ClearCal writes colours directly to your Google Calendar events via the API. The colours live on the event itself — not as a visual overlay — so they appear on every device: ✓ Google Calendar on iOS and Android ✓ Google Calendar web (any browser) ✓ Gmail calendar sidebar ✓ Fantastical, Outlook, Apple Calendar and more Set it in Chrome. See it everywhere. FULLY CUSTOMISABLE Every rule has its own colour picker — choose from all 11 Google Calendar colours. Toggle any rule on or off. When you turn a rule off, ClearCal automatically resets any events it had coloured. FREE, PRO AND LIFETIME PLANS Free — 2 rules, 7-day lookahead, no subscription needed Pro — £3.99/month — all 5 rules, full colour picker, 28-day lookahead Lifetime — £25 once — everything in Pro, all future updates, no subscription ever YOUR DATA STAYS YOURS → All classification happens inside your browser. Your calendar events never touch ClearCal's servers. → Sign-in uses Google's official OAuth — we never see your password. → ClearCal only requests permission to read and colour events. No access to Gmail, Contacts, or Drive. → No analytics, no tracking, no event logging. → Disconnect at any time — access is revoked instantly.
