1. What Are Cookies
Cookies are small text files stored on your device by your web browser. They are used to remember information about your session, preferences, and authentication state. Chyra uses a minimal number of cookies, all of which are essential for the service to function.
2. Cookies We Use
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
| chyra_logged_in | Session indicator. A non-sensitive flag (value: "1") that tells the application you have an active session. Contains no personal data or tokens. | 7 days | Essential |
| csrftoken | Cross-Site Request Forgery protection. Prevents unauthorized third-party websites from making requests on your behalf. Required for all form submissions and data modifications. | ~1 year | Essential |
| chyra_refresh | Authentication refresh token. An HTTP-only secure cookie that allows your session to be silently renewed without re-entering your password. This cookie is not accessible to JavaScript. | 7 days | Essential |
3. What We Do NOT Use
- No third-party tracking cookies. We do not use Google Analytics, Facebook Pixel, or any third-party tracking service.
- No advertising cookies. We do not serve ads or use cookies for ad targeting.
- No social media cookies. We do not embed social media trackers.
- No localStorage for sensitive data. Access tokens are stored in memory only and never persisted to browser storage.
4. Session Storage
When viewing a shared document link, we use the browser's session storage (not cookies) to store a temporary view identifier. This allows us to track viewing duration accurately and prevents duplicate view counts. Session storage is automatically cleared when you close the browser tab.
