Is Cactus Link safe to install?

What data it declares

The developer declares that it collects these kinds of data:

• User activity such as clicks, scrolling, keystrokes or network monitoring

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 links 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

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

Every site you visit. This extension can read and change the content of any page you open. What access to every site means

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

Routine for an extension

• Schedule work to run later alarms
• Open a panel beside the page sidePanel
• Store data in your browser storage
• Store data in your browser without the usual size limit unlimitedStorage

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.

• https://*/* every site
• https://debug.mycactus.dev:1443/* only debug.mycactus.dev
• https://www.mycactus.dev/* only www.mycactus.dev

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.

Sites that can connect to it

Web pages matching these patterns can open a messaging channel to it: 12 site patterns.

• https://debug.mycactus.dev/* only debug.mycactus.dev
• https://www.mycactus.dev/* only www.mycactus.dev
• https://www.sg.mycactus.dev/* only www.sg.mycactus.dev

Declared as externally connectable in the manifest: a page on these sites can exchange messages with the extension, for example to tell it you have signed in. It does not give the page access to your browser.

What the store shows
