Crouching Tracker, Hidden Email is a free Chrome extension developed by em_te. This add-on falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

The main purpose of this extension is to change the cursor when a hyperlink or button links to a URL that contains an email address. This feature serves as a warning to users that their activity may be tracked when clicking on such links.

By altering the cursor, Crouching Tracker, Hidden Email aims to alert users to exercise caution when encountering links that include email addresses. This is especially important as it can help protect users from potential spam or phishing attempts.

While there are legitimate uses for embedding email addresses in links, such as email verification during sign-ups, this extension provides an extra layer of security by raising awareness about potential tracking risks. Users can then make informed decisions about whether to proceed or not.
