Cookies and LocalStorage are standard web technologies that allow websites to store small pieces of data locally on your computer or mobile device.
They allow web applications to remember your preferences (like language choice or dark mode) without requiring logins.

Key `language`: Stores your chosen language (e.g., English, Spanish, French, German, Japanese, Chinese).
4. Managing & Deleting Browser Data
You can clear your browser storage at any time through your browser settings (Privacy / Clear Browsing Data).
