Use a private calendar link
Connect any calendar that gives you a private iCal address.
Many calendars can give you a private address (it starts with https:// or webcal://) that lets an app read your busy times. It works with almost any calendar.
- Get your calendar’s private address:
- Google Calendar (on a computer): Settings, choose your calendar under Settings for my calendars, then Integrate calendar, and copy the Secret address in iCal format.
- Outlook on the web: Settings, Calendar, Shared calendars. Under Publish a calendar, choose your calendar and Can view when I’m busy, publish it, and copy the ICS link.
- Apple iCloud: use Connect Apple Calendar instead. iCloud’s only shareable link is public.
- In linkz.io, open Connections.
- On the Private calendar link card, choose Connect and paste the address.

Keep the address to yourself. Anyone who has it can read that calendar. If it ever gets out, make a new one in your calendar and connect again.
If it doesn’t work
- “That address does not give a calendar.” Use the iCal or ICS address, not the web page address.
- “We could not reach that calendar.” Check you copied all of it.
