Privacy Policy
Last updated: May 2026
1. What We Collect
When you create an account we collect your email address. When you use the site, standard server logs may record your IP address and pages visited. We do not sell personal data.
2. How We Use It
Your email is used only to authenticate your account and send account-related notices (password resets, etc.). We do not send marketing email unless you explicitly opt in.
3. Cookies
We use a single session cookie to keep you logged in. No third-party tracking cookies are set. Anonymous analytics (page view counts) may be collected via a privacy-respecting analytics provider that does not fingerprint users.
4. Third Parties
We do not share your data with third parties except as required by law. Code execution in the playground runs in an isolated sandbox; no user code is stored after the session ends.
5. Data Retention
Account data is retained until you delete your account. You can request deletion at any time by contacting us via GitHub.
6. Security
Passwords are hashed with bcrypt and never stored in plaintext. We use HTTPS for all connections. No security system is perfect — use a unique password.
