Privacy Policy for SEOWebChecker Thunderbird Add-on

Last Updated: October 2026

SEOWebChecker ("we", "our", or "us") respects your privacy. This privacy policy explains how data is handled by the SEOWebChecker add-on for Mozilla Thunderbird.

1. No Personal Data Collection
The SEOWebChecker add-on does not collect, store, transmit, or sell any personal information, email addresses, message headers, email content, recipient lists, or browsing histories.

2. Local Analysis & Processing
All technical SEO, HTML diagnostics, heading structure evaluations, and accessibility checks are executed entirely locally within the Thunderbird client on your device. Email bodies analyzed through the "Audit Current Message" action never leave your local environment and are never transmitted to external servers.

3. External Links & Optional URL Inspection
When using the optional "URL Inspect" tool, network requests are initiated directly from your client to the user-specified destination URL solely to fetch public HTML metadata for analysis. No tracking identifiers or telemetry data are appended to these requests.

4. Contact & Support
