Unlimited calendar connections means your booking link can see every calendar you keep — with no cap that leaves some commitments invisible. It's what makes conflict detection genuinely reliable, and Cal Clear includes it free.
Why Unlimited Matters
Caps create blind spots. If a tool only checks one or two calendars, the ones it can't see become double-booking traps. The only way to guarantee accurate availability is to check them all — however many you have. See unlimited connections, free.
What You Can Connect
- Work Google Workspace account
- Personal Gmail calendar
- Shared team or family calendars
- Side-project or volunteer calendars
All merged into one availability view, checked in real time.
Performance and Privacy
Cal Clear queries connected calendars live and in parallel, so availability stays fast even with many. Each uses free/busy-only access, so no calendar's contents are exposed. See the multi-calendar check tool and the free/busy API.
Never Metered
Cal Clear won't charge for the connections that make scheduling trustworthy. Unlimited is free; Pro ($0.99/month) adds link types, not calendar capacity.
Connect Them All
Sign in at Cal Clear and add every calendar you keep.
