Cookie & Local Storage Policy

Strict first-party session and preference storage with zero third-party advertising trackers.

Zero Ad Tracking: Zopyr AI does not use third-party advertising pixels, cross-site behavioral trackers, or data-broker cookies.

1. Why Zopyr Uses Strictly Necessary Cookies & Local Storage

We use a minimal set of first-party HTTP-only cookies and browser localStorage keys strictly to keep you signed in to the Dashboard, protect forms against Cross-Site Request Forgery (CSRF), and remember your UI preferences (language, theme, display currency, and local Playground history).

2. Browser-Only Playground Conversation Storage

To protect your privacy, conversations in the Dashboard Playground (/app/playground) are stored exclusively in your own browser’s localStorage under zopyr.playground.v1 and can be cleared with one click at any time.
