What We Collect
When you use Knock, we collect:
- Account info: Your Google account email and name when you sign in
- Calendar availability: Read-only access to your Google Calendar (event start/end times and your own RSVP status) to automatically show your door as Busy or Available. We never read or display event titles, descriptions, or attendees.
- Meeting links: Permission to create calendar events on your behalf, used only to generate a Google Meet link when you let a visitor in. The temporary event is deleted immediately after the link is created.
- Knock data: Visitor names, messages, and timestamps when someone knocks on your door
- Usage data: Basic analytics to improve the service
How We Use It

What We Don't Do
