Melvbot is a single-user personal assistant. It is not offered to the public.
Melvbot requests access to Google Calendar and Google Tasks. It uses that data only to list, create, and update the owner’s events and tasks.
OAuth tokens are stored on the owner’s private server. They are used only to call Google’s Calendar and Tasks APIs.
Calendar and Tasks data is not sold, not used for advertising, and not shared with other companies except Google as needed to provide those APIs. The owner can revoke access in their Google account permissions.
