Is Leet Xt - Supercharge your Leetcode practice safe?

Low risk

Leet Xt sends the signed-in LeetCode username to a Cloudflare Worker and AWS Lambda URL once per day.

When a user visits LeetCode, the content script reads the signed-in profile link from the page and derives the username. Once per day, it sends that username in a request routed through a Cloudflare Worker to an AWS Lambda URL.
