These providers process information only as needed to deliver their services to LeetSys.
5. Cookies and Analytics
We may use cookies, local storage, and similar technologies to keep you signed in, remember preferences, measure usage, and improve the Service. You can control cookies through your browser settings, though some features may not work correctly if required cookies are disabled.

7. Data Retention and Security
We keep information for as long as needed to provide the Service, comply with obligations, resolve disputes, and enforce agreements. We use reasonable technical and organizational safeguards, but no online service can guarantee absolute security.

9. Children's Privacy
LeetSys is not intended for children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided information to us, contact us so we can take appropriate action.
