Privacy Policy

Last updated: July 13, 2026

The short version. Open Code War ranks how much you type into Claude Code. We collect the minimum needed to build the leaderboard and never see or store the content of your prompts — only counts. The whole codebase is open source, so you can verify exactly what happens.

01 What we collect

  • Anonymous device ID — a random identifier generated on your machine at install. Not linked to your name, email, or any account.
  • Usage counts — the number of prompts you submit and the number of characters in them (numbers only).
  • Country — derived by Cloudflare from your IP. We store only the 2-letter code (e.g. KR), never your IP.
  • Profile you choose to add — nickname, bio, role, company, links, projects. Optional and public.

02 What we never collect

  • The content of your prompts or Claude's responses.
  • Your code, files, or project data.
  • Your name, email, or password — there is no login.

03 How we use it

Only to compute and show the public leaderboard and your public profile. We do not sell data and we do not run ads.

04 Public information

Your nickname, bio, role, company, links, and projects appear publicly on the leaderboard and profile pages. Don't add anything you don't want to be public. Outbound links you add are marked rel="nofollow".

05 Third parties & international data transfers

The service runs entirely on Cloudflare (Workers, the D1 database, KV, and Web Analytics) and is operated from South Korea. Your data may therefore be stored and processed on Cloudflare's global network and accessed from South Korea — that is, outside your own country.

  • South Korea holds an EU adequacy decision (2021), so EU/EEA personal data may be transferred there without additional safeguards.
  • Cloudflare provides a Data Processing Addendum and Standard Contractual Clauses for its processing.
  • We use Cloudflare Web Analytics, which is cookieless and does not track you across sites.

06 Retention

We keep your data while your participation is active. You can delete all of it at any time (below). Raw events may be kept briefly for abuse prevention and re-aggregation.

07 Your rights & how to delete

Because there is no login, we identify you only by your local anonymous ID. From the plugin you can:

  • Stop collection anytime — /ocw disable
  • Clear your public profile — /ocw delete — removes your bio, role, company, links, and projects. Your nickname and usage stay on the leaderboard.
  • Erase everything — /ocw delete all confirm — permanently removes your events, statistics, and profile, and takes you off the leaderboard.

08 Children

Open Code War is not directed to children under 14 and does not knowingly collect their data.

09 Open source — verify us

Don't just trust this page. The full source, including exactly what the plugin sends, is public:
