1. What Are Cookies?
Cookies are small text files that are stored on your device (computer, tablet, or mobile) when you visit a website. They are widely used to make websites work more efficiently, provide a better user experience, and give website owners information about how their site is being used.
This Cookie Policy explains how Ferdly ("we," "us," or "our") uses cookies and similar technologies on our web application at ferdly.app.

2.3 Analytics Cookies
We have made a conscious decision to minimize tracking. Google Analytics is disabled in our configuration. We do not use third-party advertising or marketing cookies.
Privacy-First Approach: We do not use third-party analytics, advertising trackers, or social media tracking pixels. Your browsing activity on Ferdly is not shared with advertisers.
3. Local Storage & Similar Technologies
In addition to cookies, we use local storage (localStorage and sessionStorage) and IndexedDB for certain features:
- Message Cache: Encrypted message data may be cached locally for faster loading and offline access.
- Encryption Keys: Your encryption keys are stored securely in browser storage for end-to-end encryption functionality.
- User Preferences: UI settings and preferences may be stored locally.
- Draft Content: Unsent messages and posts may be saved as drafts locally.
4. Third-Party Cookies
Some features of our service involve third-party services that may set their own cookies:
- Supabase: Our authentication and database provider may set cookies for session management.
- Vercel: Our hosting provider may set essential performance and security cookies.
- Google Sign-In: If you choose to sign in with Google, Google may set cookies according to their own cookie policy.
We recommend reviewing the privacy and cookie policies of these third-party services for more information about their practices.
