Privacy notice

What we collect

• Account data: when you sign in with Google, we receive your name, email address, and profile picture.
• Approval status: whether an admin has approved your account.
• Group & calendar data: groups you create or join, and appointments, locations, attendees, and reminder preferences you or other group members enter.
• Push subscriptions: if you enable notifications, a browser-issued subscription identifier used to deliver reminders to your device.

Who we share it with

Google (sign-in), Supabase (hosting, database, and scheduled reminder delivery), Resend (approval and admin-notification emails), and — if you enable notifications — your browser vendor's push service (e.g. Google, Mozilla, or Apple), which relays an encrypted reminder payload it cannot itself read. Ask an admin for the full technical breakdown of what each service receives.

AI assistant (Claude) connector

A member can choose to connect Kin to Claude, Anthropic's AI assistant, to ask things like "when are we both free on a Saturday?" or to book or move an appointment. This only happens after that member approves it on Kin's own consent page, and they can revoke it any time under Settings. While they use it, Claude can read what that member can already see in Kin — including other group members' names, appointments, birthdays and recipe ratings — and add or change appointments on their behalf (never delete them). That information then becomes part of their Claude conversation and is handled under their own Anthropic account settings. Kin never sends anything to Anthropic on its own.

Your data, your group

Calendar and group data is only visible to members of that group. You can ask to have your account and data removed at any time by contacting an admin.
