TweakThis privacy policy: https://tweakthis.io/privacy

The extension section (https://tweakthis.io/privacy#extension) describes what the add-on sends: when you pick an element or record a guided flow and press Send, the note, the page address and title, the element context (selectors, HTML, styles), the viewport and a screenshot go to your TweakThis account on tweakthis.io. When you open the menu or pins on a project page, the page address is used to load feedback already left there. With optional technical data allowed, it reports when a site-access prompt was declined or a capture could not start (no address or content). It does not track browsing, show ads or sell data.
