Privacy Policy
Last updated: March 12, 2026
Overview
SEO Lens ("the Extension") is a Chrome browser extension for SEO page auditing. This policy explains what data is collected, how it is used, and your rights regarding that data.
Data We Collect
The Extension collects only the data necessary to perform SEO analysis:
- Page content — the active tab's DOM is read locally in your browser to extract SEO data (title, meta tags, headings, links, schema markup). This data never leaves your device unless you explicitly use an AI feature.
- API keys — if you choose to use AI features (meta generation, FAQ schema, content gap analysis), you provide your own Claude API key and/or Google PageSpeed API key. These keys are stored locally in
chrome.storage.localand are only sent directly to the respective APIs (Anthropic / Google). We never receive or store your API keys. - Scan history — optionally saved locally in
chrome.storage.localon your device. Never synced or transmitted anywhere. - Theme preference — stored locally in
chrome.storage.local.
Data We Do NOT Collect
- We do not collect any personal information (name, email, location, etc.)
- We do not track browsing history or visited URLs
- We do not use analytics, telemetry, or crash reporting
- We do not have any servers — there is no backend
- We do not sell or share any data with third parties
Third-Party Services
When you use AI features, data is sent to third-party APIs:
- Anthropic Claude API — page content (title, meta, headings) is sent to generate meta tags or FAQ schemas. Subject to Anthropic's Privacy Policy.
- Google PageSpeed Insights API — the page URL is sent to Google to retrieve performance scores. Subject to Google's Privacy Policy.
These features are optional and only activated when you explicitly click the relevant button.
Permissions Used
- activeTab — to read the currently open page for SEO analysis
- scripting — to inject the content script that reads page DOM
- storage — to save your settings and scan history locally
- tabs — to open background tabs for competitor comparison and bulk scanning
- host_permissions (<all_urls>) — required to analyze any webpage you navigate to
Data Retention
All data is stored locally on your device in Chrome's local storage. You can clear it at any time via the Extension's Settings tab or by removing the Extension from Chrome.
Children's Privacy
SEO Lens is not directed at children under 13. We do not knowingly collect data from children.
