Code proof for
every solve.
LeetCode's public profile only shows that you solved something. The Upsolve Club extension records how: your code, your attempts, your time. Ranked competitions only count solves that carry it.

What it records
- The code you submit and its verdict
- Runtime and memory, with the beats-% LeetCode shows
- Failed attempts before your Accepted
- Time from opening the problem to submitting
- Large pastes into the editor (shown to rivals as a trust signal)
What it never touches

- Your LeetCode password or cookies
- Other tabs, browsing history, or other sites
- Runs of “Run code” (only real submissions)
Who sees your code is your choice (Settings → Privacy). Inside a competition, its reveal rule applies: by default a rival sees your solution only after solving that problem too. The extension is open source: every line is in the Upsolve Club repository.
