We do not sell your personal information to third parties.

4. Cookies and Tracking

The Site may use cookies and similar technologies to remember your preferences, understand how visitors use the Site, and improve your experience.

We take reasonable technical and organizational measures to protect your information from unauthorized access, loss, misuse, or alteration. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.
