What data it declares

The developer declares that it collects these kinds of data:

• Web history the list of pages you visit
• Website content such as text, images or links on the pages you open

The developer also certifies that your data is not sold to third parties outside approved uses, not used for purposes unrelated to the extension's core function, and not used to decide creditworthiness or lending.

Pages it runs its code on

A content script is code the extension injects into pages matching these patterns. On those pages it can read and change what you see, whether or not a host permission is listed above.
