Cookie Policy

1. What Are Cookies

Cookies are small text files stored on your device by your web browser. They allow websites to remember your preferences and maintain sessions.

2. Our Cookie Philosophy

NullKeep uses cookies only for essential functionality. We do not use tracking cookies, advertising cookies, or third-party analytics cookies. We believe in minimal data collection — consistent with our zero-knowledge architecture.

3. Cookies We Use

4. Cookies We Do NOT Use

• ❌ Google Analytics or any analytics tracking
• ❌ Facebook Pixel or advertising cookies
• ❌ Third-party tracking cookies
• ❌ Behavioral profiling cookies
• ❌ Cross-site tracking cookies

5. Browser Extension

The NullKeep browser extension does not use cookies. It stores data locally using:

• chrome.storage.local — for encrypted vault data and settings
• chrome.storage.session — for temporary session keys (cleared when browser closes)

This data never leaves your browser unless you explicitly enable cloud backup.

6. Managing Cookies

You can manage cookies through your browser settings:

• Chrome: Settings → Privacy and Security → Cookies
• Firefox: Settings → Privacy & Security → Cookies
• Safari: Preferences → Privacy → Cookies
• Edge: Settings → Cookies and site permissions

Note: Blocking the nk_session cookie will prevent you from staying logged in to your NullKeep Cloud account.

7. Changes to This Policy

If we ever add new cookies (which is unlikely given our privacy-first approach), we will update this page and notify registered users.
