Privacy policy
Last updated August 2026. Short version: no user data collected.
What we collect
Nothing. The extension has no accounts, no analytics SDKs, and no telemetry. We do not build profiles and we do not sell or share anything, because there is nothing to sell or share.
Guardian Mode
The quick risk check runs entirely inside your browser using local pattern matching. It makes no network requests. Your draft never leaves your machine during a Guardian Mode check.
Full analysis
A full analysis only happens when you explicitly click Analyze My Post or use the right-click menu. That action opens a new tab and passes the selected text so the web app can score it. Text is processed to return your result and is not retained afterwards.
Permissions, and why
activeTab and scripting let the popup read text you have selected on the current page, only while the popup is open. storage holds the draft you handed off for a single moment so the popup can prefill it, then removes it. contextMenus adds the right-click entry. No permission is used for tracking.
Children
The extension is not directed at children under 13 and collects no data from anyone.
Changes and contact
