CSV Form Filler does not collect, transmit or store any data.
The CSV file you load is read inside your browser with the standard FileReader API.
Its contents stay in the extension popup for as long as that popup is open, and are used only to
fill fields on the page you chose. When the popup closes, they are gone.
activeTab — lets the extension act on the tab you are currently looking at, and only after you open the popup and click. It is how the extension sees which form fields exist on that page and how it writes values into them.scripting — used once, to inject the field-detection routine into that same active tab when the popup opens on a page where the content script is not already present (for example a page that was open before you installed the extension).Neither permission can reach a tab you are not on, and nothing runs before you click.
The whole point of the extension is that it fills a form on whatever page you happen to be on, so it is declared for all sites. It does nothing at all on any page until you open the popup, load a file and press Fill.
If this policy ever changes, the updated version will be posted at this URL with a new date.
