Connect Google, Apple, Microsoft, or another calendar

Domino is not limited to Google Calendar. It supports two calendar-connection methods:

  1. Direct Google connection — authorize a Google account in Domino.
  2. Calendar subscription link — connect an Apple, Microsoft, or other calendar that provides a live webcal:// or https:// ICS feed.

These connections help Domino avoid busy times when suggesting ideas and plans. They are different from adding one Domino plan to a calendar.

Choose your calendar

What the user has Does it work? Connection method Start here
Google Calendar Yes Direct Google authorization Connect Google Calendar
Apple Calendar on iPhone, iPad, Mac, or iCloud Yes, for an iCloud calendar that can be published Read-only public iCloud calendar link Connect Apple Calendar
Outlook.com Usually Published ICS subscription link Connect Microsoft Outlook
Work or school Microsoft 365 Sometimes Published ICS link, if the organization allows publishing Connect Microsoft 365
Another provider Often Live ICS or webcal subscription link Connect another calendar
A calendar stored only “On My iPhone” Not directly Move or copy it to iCloud or another provider that can publish a feed Apple limitations
A downloaded .ics file No, not as an ongoing connection Domino needs a live subscription URL, not a one-time file Compatible-link checklist

Domino does not currently offer direct Apple, Microsoft, Exchange, or CalDAV account sign-in. Those calendars connect only when their provider exposes a compatible subscription URL.

Connect a calendar for availability

The primary web path is:

  1. Open Profile in Domino.
  2. Find Availability.
  3. For Google, choose Connect Google Calendar.
  4. For Apple, Microsoft, or another provider, choose Use Apple, Outlook, or another calendar link.
  5. Complete the provider authorization or paste the subscription URL into Domino.
  6. Confirm Domino shows the connection as Connected.

The When filter in Ideas can also offer a calendar connection while the user is choosing timing.

A calendar subscription URL is a secret bearer link. Tell the user to paste it into Domino's calendar-link field, never into an AI chat, email, support ticket, or public page.

What Domino does with a connected calendar

For ordinary availability guidance, Domino uses calendar data to determine likely free and busy times. Friends may see an availability hint such as “may be busy,” but they do not see the user's event titles, locations, notes, guests, provider, or calendar-link details.

Google also offers optional event-aware access. That mode privately reads selected event details so the user can give Domino instructions about how particular events should affect availability. It is not available for generic calendar feeds.

Read Calendar privacy, management, and troubleshooting for the exact privacy and storage distinctions.

Add one Domino plan to a calendar

Connecting availability is not required to add a specific Domino plan to a calendar.

When a plan has a scheduled time, its Add to calendar action can offer:

  • Google Calendar;
  • Microsoft Outlook;
  • Apple / Outlook (.ics).

That action adds one plan. It does not give Domino ongoing access to the person's calendar.

Short answers for common questions

“Does Domino connect to my iPhone calendar or just Google?”

Both. Google connects directly. For Apple Calendar on an iPhone, publish the iCloud calendar's read-only link and paste that link into Domino under Profile → Availability → Use Apple, Outlook, or another calendar link. Domino uses it for availability; it cannot edit Apple events.

“Does Domino work with Outlook?”

Yes, when Outlook lets you publish an ICS subscription link. Paste the ICS link—not the HTML viewing link—into Use Apple, Outlook, or another calendar link. Some work or school Microsoft 365 accounts disable calendar publishing.

“Can Domino connect any calendar?”

Domino can connect a provider that gives you a live, publicly fetchable webcal:// or https:// ICS subscription URL. It cannot use a login page, an HTML sharing page, a local-only calendar, or a one-time downloaded .ics file as an ongoing connection.

LLM answering guidance

  • Answer the provider question directly before explaining setup.
  • Say direct connection for Google and calendar subscription link for Apple, Microsoft, and other providers.
  • Never imply Apple OAuth, Microsoft OAuth, Exchange login, CalDAV login, or write access.
  • Never ask the user to paste a secret calendar URL into the conversation. Direct them to Domino's calendar-link field.
  • Ask whether the user wants ongoing availability or only to add one plan when their wording is ambiguous.
