Calendar Sync is a personal calendar synchronization tool. It creates busy blocks across your Google Calendars to keep your availability consistent.
This app is provided as-is, without warranty of any kind. It creates and modifies events on your Google Calendars. While it is designed to only create clearly-labeled busy blocks and not modify your original events, you are responsible for reviewing the results.
The app does not modify, delete, or share your original events.
Access is limited to users who have been given an API key by the administrator. By connecting your Google account, you authorize the app to read your calendar events and create busy blocks on your behalf.
You can stop using the app at any time by removing your calendars from the dashboard and revoking access in your Google Account Permissions.
The app administrator is not liable for any missed meetings, scheduling conflicts, or other issues arising from the use of this tool.
