What data it declares

The developer declares that it collects these kinds of data:

• Authentication information such as passwords, credentials or PIN codes
• 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.

This is the developer's own declaration in the Chrome Web Store. We cannot check it against what the extension does.

What Chrome asks you to allow

When you add it, Chrome asks you to allow it to:

• Read and change your data on a number of websites
• Read your browsing history

Derived from the manifest by Chrome's documented rules; the dialog's exact wording depends on your Chrome version and language. Chrome asks again if an update requests more.

What it can reach

Specific sites only: 7 match patterns.

• https://search.shopping.naver.com/* only search.shopping.naver.com

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.
