Caltsu connects to your calendars via secure OAuth. When an event is created on one calendar, Caltsu automatically creates a 'Busy' block on your other calendars. Changes and deletions are synced in real-time using webhooks.
Absolutely. We use industry-standard OAuth 2.0 for authentication. We never store your passwords, and your calendar data is encrypted both in transit and at rest.
We support Google Calendar, Microsoft Outlook (including Office 365), and Apple Calendar. You can sync between any combination of these platforms.
No. That's the whole point of Caltsu! We only create 'Busy' blocks on your work calendars. The actual event details stay private on your personal calendar.
Your calendars will stop syncing, but all existing busy blocks will remain. You won't lose any data. You can restart your subscription at any time to resume syncing.
