Is leetcode cheatsheet safe?

Medium risk

leetcode cheatsheet sends problem page HTML, URL, title, language, and editor code to RapidAPI when you click write solution.

When you use the write-solution button on LeetCode pages, the extension reads the current problem description HTML, page title, URL, selected language, and editor contents. It posts that data to my-store2.p.rapidapi.com for storage and ships the RapidAPI key used for those requests in the extension bundle.
