Is Web Highlighter safe to install?

What data it declares

The developer declares that it does not collect or use your data.

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.

The listing does not link to a privacy policy.

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 all your data on all websites
• Read your browsing history
• Read the icons of the websites you visit

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

No site access is declared in the manifest, so it cannot read the pages you open on its own.

Reaches your browsing data or every site

• See the address and title of every tab you have open tabs

Routine for an extension

• Read site icons favicon
• Run work in a hidden page offscreen
• Open a panel beside the page sidePanel
• Store data in your browser storage

Pages it runs its code on

It runs its own code on every page you open: the manifest declares a content script for all sites.

• <all_urls> every site
• *://*.youtube.com/* youtube.com and all its subdomains

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.

What it may ask for later

Not granted when you add it: Chrome asks you the moment the extension requests one of these, and you can refuse.

Has it asked for more over time?

This is the question a permission list on its own cannot answer. An extension that shipped narrow and widened later is a different proposition from one that always asked for the same thing.
