This Privacy Policy explains how SEO Schema Visualizer handles information when you use the extension. By installing or using SEO Schema Visualizer, you agree to this policy.
Data Collection
SEO Schema Visualizer does not collect, store, sell, or share personal data, browsing history, or device identifiers.
How the Extension Works
SEO Schema Visualizer processes structured data locally in your browser to:
- Detect JSON-LD schema markup
- Show a badge indicator when valid JSON-LD is present
- Visualize schema entities and relationships in an interactive graph
- Let users view, copy, and export JSON-LD data
All analysis and rendering are performed on-device. SEO Schema Visualizer does not transmit page content or extracted schema data to external servers.
Permissions
SEO Schema Visualizer uses the following permissions only for core functionality:
Host permissions (site access)
Used to enable page-level structured data detection across supported sites, including badge alerts for valid JSON-LD.
activeTab
Used to access the currently active tab when you open/interact with the extension, so it can analyze structured data on that page.
Scripting
Used to run extraction logic on web pages to detect JSON-LD and relevant schema markup for visualization and badge functionality.
Data Storage
SEO Schema Visualizer does not maintain user accounts and does not store personal information on remote servers.
Third Parties
SEO Schema Visualizer does not use third-party analytics or trackers to profile users.
Changes to This Policy
We may update this Privacy Policy from time to time. Updates will be reflected on this page with a revised effective date.
