Pace works natively with Google Calendar - read-only by default, optional write-back
Pace connects to Google Calendar to read what's already on your week, plan your goals around it, and (if you opt in) write planned sessions back to a dedicated Pace calendar you control.
Pace sees event times, durations, and whether you're free or busy. It doesn't need to see what your meetings are about to plan well around them.
You can connect Pace without giving it any write access. It suggests when to do things; you add them to your calendar manually if that's your preference.
If you'd rather see the plan natively in Google Calendar, opt in and Pace will write planned sessions to a dedicated calendar (separate from your existing ones). You can toggle that off anytime.
Pace handles multiple Google Calendars (work + personal, shared calendars, etc.) so the plan doesn't assume you only have one.
