CalendarMate information
What is CalendarMate?
CalendarMate is a privacy-first scheduling tool for people who use Proton Calendar, Tuta, Apple iCloud, Fastmail, or any CalDAV-compatible calendar.
Unlike Calendly and similar tools, CalendarMate never asks you to connect your calendar via OAuth or hand over access credentials. Instead, you paste in a read-only ICS feed URL — CalendarMate reads your busy/free times, and presents a clean booking page to anyone you share your link with.
Visitors pick a date and time, fill in their name and email, and the booking lands in your inbox. No account required for the person booking.
Key features:
- Works with Proton Calendar, Tuta, iCloud, Fastmail, Google Calendar, and any ICS-compatible source
- Short shareable booking link (e.g. calendarmate.app/r?c=xxxxx) — safe to put in an email signature or on a business card
- Choose between video call link (Zoom, Google Meet, etc.) or WhatsApp call as your meeting type
- Configurable working hours, meeting duration, buffer time, and timezone
- Booking confirmation emails sent automatically
- Installable as a PWA on desktop and mobile
- Pay what you want — including free
