What the TextSight Chrome & Edge extension can see, can do, and (importantly) cannot do. Required reading before you install.
When you install from the Chrome Web Store, you'll be asked to grant these. Here's what each one does:
activeTabLets us see the text you've selected when you click our icon or right-click. Only the active tab. Only when you trigger us. Permission is revoked the moment you switch tabs.
contextMenusLets us add "Check with TextSight" to the right-click menu. Doesn't see anything you don't right-click.
storageStores your TextSight session token locally so you stay logged in. Stored only in extension storage — never sent to other sites.
api.textsight.aiLets us send selected text to our own API for analysis. That's the only host the extension talks to.
If you see any of these in the install prompt, something is wrong (it's not our extension):
<all_urls> / "Read and change data on all sites"We could read every page in the background if we asked for this. We don't.
tabs / "Read your browsing history"We don't need to see your other tabs or your history.
cookiesWe don't read or modify cookies on any site you visit.
The extension uses a service worker only (event-driven). No background tab observing the web.
api.textsight.ai.At no point does the extension know what page you're on, what site, what you searched for, who you are.
api.textsight.ai.That's the entire list.
The extension reports two pieces of telemetry, both anonymous:
You can disable telemetry entirely in Extension → Options → Privacy.
The extension source is on GitHub: github.com/textsight/extension. Audit it. Build from source. Open issues. PRs welcome.
