⚠️ Exception: Domain names are only included in error tracking to help us diagnose and fix issues.

3.3 MCP Server Privacy

Our free Model Context Protocol (MCP) server at mcp.domaindetails.com:

  • Does NOT store domain queries beyond temporary caching for performance
  • Does NOT collect or store personal information about API users
  • May log IP addresses temporarily for abuse prevention and rate limiting
  • Operates with the same privacy-first principles as our main service

8. Browser Extension Privacy

If you use our browser extension for Chrome, Edge, Firefox, Safari, or another supported browser, the following additional privacy considerations apply:

8.1 Extension Permissions

The Domain Details browser extension requires limited permissions:

  • Access to active tab URL (to extract domain name for lookup)
  • Scripting permission to read basic page metadata only when a marketplace URL does not contain the offered domain
  • Context-menu permission for explicit right-click lookups
  • Storage permission to save preferences and observed snapshots locally

8.2 Data Collection

The browser extension:

  • ✗Does NOT: Track your browsing history or visited websites
  • ✗Does NOT: Send domain names to our servers unless you explicitly click to perform a lookup
  • ✓Does: Store your preferences locally in your browser
  • ✓Does: Present anonymous usage analytics before collection, enabled by default with an immediate and persistent opt-out

8.3 Lookup and Analytics Processing

When you request a registration lookup, the researched domain is sent in an encrypted POST body to ext.domaindetails.com, an independent Cloudflare Worker that queries public RDAP or WHOIS services. It has no application database attached and does not retain lookup results. Requested marketplace searches send the domain to api.domaindetails.com.

If anonymous analytics are enabled, allowlisted technical and interaction events are sent to PostHog EU through our first-party proxy at f.domaindetails.com. These events use a random installation identifier and may include browser and extension version, feature name, general detection method, success state, coarse counts, and duration.

Extension analytics never include searched domains, marketplace provider names, complete page URLs, page titles, raw WHOIS/RDAP data, local observed history, contact data, or Domain Details account identifiers. PostHog person profiles are disabled for extension events.

9. Children's Privacy

Our service is not directed to children under 16. We do not knowingly collect personal information from children. If you believe we have collected information from a child, please contact us immediately.

10. Changes to Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by:

  • Posting the new Privacy Policy on our website
  • Sending an email to pro subscription users
  • Displaying a notice in our service
