Privacy

No accounts. You don't log in and we don't ask for your name, email, or any personal identifier.

Analytics. If enabled, we use Cloudflare Web Analytics — privacy-friendly and cookieless. It counts aggregate page visits, sets no cookies, and does not track you across sites.

Local storage. We store one value in your browser: your light/dark theme choice. It never leaves your device.

Leaderboard submissions. If you choose to submit, we store the nickname you type (shown publicly), your strategy definition and its backtest metrics, a timestamp, and a one-way hash of your IP address used only for spam rate-limiting. We do not store your raw IP. Don't put personal information in your nickname.

Advertising. None currently. If display ads are added later, this policy will be updated to disclose ad cookies and provide opt-out guidance before any ads run.
