PRIVACY — ZERO DATA COLLECTION
This extension does not collect, transmit, or store any data. Period.
Every analysis runs entirely in your browser using client-side JavaScript. No page content, URLs, or browsing history is sent to any server. No analytics. No tracking pixels. No cookies.
The only permissions requested are:
— activeTab: access the current page only when you click the extension icon
— scripting: inject the analysis script to read the page's HTML
We believe SEO tools should help you, not spy on you. Full privacy policy at https://seobolt.io/privacy
WHAT MAKES THIS DIFFERENT?
Most SEO browser extensions either:
— Require an account and API key before you can use them
— Send your browsing data to their servers
— Lock basic features behind a paid subscription
— Load slowly because they phone home on every page
SEObolt SEO Checker does none of that. It works instantly, locally, and completely free.
