LittleBig Universal CalDAV for FluentBooking

1. In your site’s WordPress admin, go to Settings > Integrations > CalDAV (Generic) and enter your Zoho CalDAV base URL. Use the URL that matches your Zoho datacenter:
   • https://calendar.zoho.com/caldav — Americas / default
   • https://calendar.zoho.eu/caldav — Europe
   • https://calendar.zoho.in/caldav — India
   • https://calendar.zoho.com.au/caldav — Australia
   • https://calendar.zoho.jp/caldav — Japan
2. Each host generates a Zoho app password: log in to myaccount.zoho.com, go to Security > App Passwords, and create a new password for CalDAV access.
3. In FluentBooking > Host Settings > Remote Calendars, select CalDAV (Generic) and enter the Zoho email address as the username and the app password as the password.

Some CalDAV servers — including Zoho Calendar — do not accept your main account password for CalDAV access. An app password is a dedicated token you generate in your account security settings. It works only for CalDAV and can be revoked independently of your main password.

This plugin is designed with GDPR in mind. Here is a full breakdown of how it handles personal data:

Personal data transmitted

When a booking is created, updated, cancelled, or deleted, the plugin sends the following data to the CalDAV server you configure: attendee name, attendee email address, booking start/end time, and any booking notes. No other personal data is transmitted. Nothing is sent to the plugin author or any third party.

Data stored locally (WordPress user meta)

The following values are stored in WordPress user meta for each calendar host:

• Encrypted CalDAV credentials (username and password or app password)
• CalDAV server URL and discovered calendar list
• Per-booking event URL and UID (used for updates and deletion)
• A flag indicating whether a connection needs re-authorisation

All credential values are encrypted with libsodium (sodium_crypto_secretbox) before storage. They are never stored in plaintext.

Data deletion

When the plugin is deleted (not just deactivated), uninstall.php removes all plugin user meta for every user. You can also disconnect an individual host at any time via FluentBooking > Host Settings > Remote Calendars, which deletes that host’s credentials and cached calendar data immediately.

Your CalDAV server as a data processor

The CalDAV server you connect to (e.g. Zoho Calendar, Fastmail, iCloud) receives and stores personal data from your bookings. As the site owner and data controller, you are responsible for ensuring that server complies with applicable data protection law and that you have a lawful basis for transferring attendee data to it. Review the privacy policy of your CalDAV provider before use.

No telemetry

This plugin makes no outbound requests except to the CalDAV server URL you explicitly configure. No usage data, error reports, or analytics are sent anywhere.

No. This plugin is completely independent from the Nextcloud Calendar integration included with FluentBooking Pro. You can use both simultaneously.
