Calendar MCP is a privately operated integration maintained by Roger Wang. This notice covers its Calendar assistant and associated Gmail scheduling, alert and follow-up automations. Updated November 14, 2026.
The integration reads event titles, dates, times, attendee information, response status and calendar identifiers from accounts that authorize Google Calendar access. Associated Gmail automations access relevant messages, message headers, participants and scheduling details to deliver alerts and operator-directed follow-ups. Existing Gmail authorizations may include permission to send and modify mail and manage basic mail settings. The WhatsApp assistant itself reads configured alert copies and authorized group messages; its Calendar connection is read-only.
Information is used to answer schedule questions, deliver requested alerts and support operator-directed email follow-ups. Calendar and Gmail access is limited to accounts that authorize the integration. Relevant questions, recent group conversation and requested schedule data are processed through Claude Code using the operator’s Claude account. Responses and alerts are sent through WhatsApp to the designated group, where other group members can see them. Google, Anthropic and WhatsApp process data under their respective service terms and privacy policies.
Authorization credentials, delivery records and limited conversation history are stored on the operator’s computer. Calendar reads do not edit events. The operator can stop the service, delete local records, revoke Google access, or unlink the WhatsApp device. Copies already sent to email, WhatsApp recipients or service providers may remain under those recipients’ or providers’ controls.
Google user data is not sold, used for advertising or used by this integration to train general-purpose AI models. Access and transfer are limited to providing the requested features. Use of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements.
