I am glad you find it useful. The permission "Access your data for all websites" is broad but that's what gives Sticky Ducky the ability to access and clean the pages automatically. This is similar to how the adblockers work. If it had the current tab permission instead, every time you open a page, you'd have to click on the extension button to run it. That would be tedious on a desktop and nearly impossible on mobile. Perhaps I should write this on the github project page.
