1. What Are Cookies?

Cookies are small text files stored by the browser on the User's device when visiting a website. They help websites remember preferences and function properly.

2. Essential Cookies

These cookies are necessary for the platform to function. We use them without consent because the platform cannot operate without them.

Cookie Purpose Expiry
birenko_session Session management (login state) Browser close / 2 hours
XSRF-TOKEN CSRF protection (security) Browser close / 2 hours
birenko_theme Theme preference (display settings) 1 year

3. Functional Storage

The User's theme preference (e.g., "synthwave", "light") is stored in the browser's localStorage and in a functional cookie (birenko_theme) so the server can remember the display settings. This cookie contains only the theme name and may be used in aggregate usage statistics visible to system administrators.
