A few things worth knowing before installing this;
On every page load it contacts jtmate.com to fetch a persistent token, which gets attached to all subsequent requests. This means your browsing is tracked across sessions, not just by IP. Your current URL, page title, language, and currency are sent to oversea.mimixiaoke.com with each request. (I assume the dev's nginx server/proxy)
The script also runs on every website, not just shopping sites, and all the UI it injects is fetched live from their server, so the developer can change what runs in your browser without pushing a script update.

The script runs only on the websites it is explicitly designed to match and exits immediately on all others. This behavior can be directly verified by reviewing the source code.

When executed on a matched site, the script sends a request to jtmate.com to obtain a token. This token identifies the user’s logged-in session on jtmate.com and is an essential and critical parameter for subsequent cashback operations, determining exactly which user the cashback will be credited to.

The script is fully open source and readable in plain text, with no compression or obfuscation. It is open to public scrutiny at all times, allowing anyone to verify its behavior. You can use it with confidence, knowing its security and transparency are fully verifiable.
