This Cookie Policy explains how Kestralis ("we", "our", or "us") uses cookies and similar technologies when you use our website and applications. This policy should be read alongside our Privacy Policy and Terms of Service.

What Are Cookies?

Cookies are small text files stored on your device (computer, tablet, or mobile) when you visit a website or use an application. They help websites remember your preferences and improve your experience.

Essential Cookies

These cookies are necessary for the app to function properly. They enable core features such as:

• Authentication: Remember your login status (if cloud sync enabled)
• Security: Protect against unauthorized access and fraudulent activity

All analytics data is anonymous and cannot be used to identify individual users.

Advertising Cookies
