SEOSID browser extension: privacy policy

Last updated 3 November 2026

What the extension does

The SEOSID extension for Chrome and Firefox checks the SEO of the web page you are looking at when you click its icon: title, meta description, headings, images, links, structured data, social previews, AI-search readiness and technical basics.

What it reads, and when

• It reads the open page only when you click the SEOSID icon. It does not run in the background and does not track your browsing.
• To check the page, it may request files from the same website (for example robots.txt, llms.txt, sitemap.xml) and the site's own links, to find broken links.
• The page check runs in your browser. Its results are not sent to SEOSID.

If you sign in to SEOSID

• The extension sends the address (URL) of the page you check to app.seosid.com, to show what your SEOSID account knows about it: your websites' issues, Search Console numbers and backlink statuses.
• It stores a sign-in token in your browser's extension storage. You can sign out from the extension or from app.seosid.com > Browser extension at any time.
• The extension never receives your passwords, the logins SEOSID keeps for backlink sites, or payment details.

What we never do

• We do not sell or share data, use it for advertising, or use it to decide creditworthiness or for lending.
• We do not collect browsing history, form contents, keystrokes or personal communications.

The use of information received from the extension complies with the Chrome Web Store User Data Policy, including the Limited Use requirements, and with Mozilla's Add-on Policies. In Firefox, signing in asks for your permission before any data is shared with app.seosid.com.
