External services

This plugin relies on two external services. Both are part of the BMLT (Basic Meeting List Toolkit) ecosystem — free, open-source tools built for Narcotics Anonymous service bodies (https://bmlt.app).

1. Crumb Widget CDN

The widget JavaScript is loaded from a CDN operated by the BMLT project.

• Service: cdn.aws.bmlt.app — delivers the Crumb Widget JavaScript file
• Purpose: Provides the JavaScript component that renders the meeting list interface
• Data sent: Standard HTTP request headers (IP address, browser user-agent, referring URL). No personal or meeting-search data is sent to the CDN.
• When: The script is loaded once per page load on any page that contains the [crumb] shortcode
• Privacy policy: https://crumb.bmlt.app/privacy.html
• Terms of use / License: https://github.com/bmlt-enabled/crumb-widget/blob/main/LICENSE

2. BMLT Server (meeting data)

The widget fetches meeting data from a BMLT server whose URL you configure in Settings → Crumb. This server is typically operated by a regional NA service body and is not a service operated by the Crumb project.

• Service: Your configured BMLT server (e.g. https://your-region.bmlt.app/main_server/)
• Purpose: Retrieve NA meeting listings (names, times, locations, formats) to display in the widget
• Data sent: Search query parameters (filters, keyword, selected formats). If geolocation is enabled and the user consents via a browser prompt, the user’s geographic coordinates are also sent to this server.
• When: On each search or filter action within the widget
• Privacy policy: Determined by the operator of your configured BMLT server. Learn more at https://bmlt.app.
