dmcal is a private, invitation-only scheduling tool for a small tabletop gaming group. It is not a commercial service.
Data is stored in Google Firebase (Firestore) and used solely to schedule sessions. Text messages are delivered through Twilio. We do not sell your information or share it with anyone else, except the usage analytics described below, and we do not use it for marketing. Mobile numbers and SMS consent are never shared with third parties for their own marketing purposes.
The dmcal website and app use Google Analytics (GA4) to count visits. The app reports only the type of page viewed (a route pattern such as “Session”) and its title, never campaign, session or user identifiers, RSVP links or invite codes. Google Analytics sets cookies in your browser; you can block them with your browser settings or an ad blocker without affecting dmcal.
Untick “Text me when sessions are scheduled or changed” in dmcal or reply STOP to any text to stop messages. Ask your DM to remove you from a campaign to stop sharing your availability with that group.
