Is Reclaim a calendar app?
Reclaim is designed to be a calendar assistant that works with your Google Calendar (not replace it). We built Reclaim to enable you to work where you already do. You can use our Planner to make changes to your Reclaim-managed events, install our Google Calendar and Gmail Add-on to get the power of Reclaim directly in Google Calendar's web UI, and/or add our Slack integration to work with Reclaim there.
Supported calendar services
Currently, Reclaim only has full support for Google Calendar, but support for other calendar services -- notably Office 365 -- is on the roadmap.
This means you can't use a non-Google Calendar as your main calendar in Reclaim (i.e., for blocking time for your Tasks, Habits, Smart 1:1s). However, you can share a non-Google Calendar -- via iCloud, Outlook, or another external calendar service -- and sync events from that calendar to another Google Calendar using our Calendar Sync feature. You can learn more about how to share and sync non-Google Calendars here.
Reclaim schedules on your primary calendar
Today, Reclaim only will schedule time blocks on the primary calendar of your main account email in your Reclaim account. We do this because the primary calendar tends to be where all inbound meetings will be scheduled for the majority of Google Calendar users.
What is a "primary calendar" in Google?
Google Calendar (and most other calendaring platforms) have a concept of "primary" and "shared" calendars. Primary calendars are special: they are the calendar that Google relies on for most scheduling workflows, and they are where most events will land by default. Shared calendars, on the other hand, are simply "sub-calendars" that Google doesn't consider in most scheduling workflows.
For example, if you use Google Calendar's "Find a Time" feature when trying to book time with someone in your workspace, it will only ever show events from the primary calendar. All other calendars will be ignored. This is a big reason why Reclaim's Calendar Sync feature exists -- to help merge events from other calendars to your primary calendar so that they show as unavailable to your colleagues.
To identify your primary calendar, navigate to Google Calendar and look on the left hand side. The first calendar displayed is always your primary.
Reclaim can consider availability from other calendars
As mentioned above, Reclaim schedules events on the primary calendar of your main account email only. However, it can consider availability from other calendars when it blocks time -- either by you using our Calendar Sync feature, or our Connected Calendars feature.
Calendar Sync allows you to literally duplicate and copy events across calendars so that Reclaim will see you as unavailable, and so that others in your workspace will see you as unavailable when looking for times on your primary calendar.
Similarly, Connected Calendars allows you to designate other calendars for Reclaim to consider when blocking time, but it doesn't duplicate events across calendars -- that means that others who go to book time with you within Google Workspace won't see events from other calendars.
