Google Calendar sync

Two-way, once connected from Settings: your real calendar's busy times block HykeCal slots, and confirmed HykeCal bookings appear as real events on your calendar.

Setting it up

1. Enable the Google Calendar API in Google Cloud Console.
2. Create an OAuth client (Web application type) under Credentials.
3. Register <your-app-url>/api/auth/google/callback as the redirect URI.
4. Set GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET as environment variables.
5. Click "Connect Google Calendar" on the Settings page.

Scopes

Only calendar.freebusy and calendar.events are requested — deliberately not the full calendar scope, which also grants calendar management HykeCal never needs.

If sync ever fails

Silently, on purpose. A calendar-sync hiccup logs an error but never blocks or reverses an already-confirmed booking — the booking itself is always the source of truth.
