 - `getAllQuery(): Record<string, string | string[]>` - Parses the current URL's query string and returns an object with key-value pairs. Values appear as arrays when the same key is used multiple times.
 
+### DeviceUtil
+
+- `getDevice(): DeviceInfo` - Detects the user's device environment. Returns information about device type (mobile/tablet/desktop) and operating system (iOS/Android). Uses navigator.userAgent for detection and provides safe fallback for SSR environments.
+
 ### CookieUtil
 
 - `setCookie(name: string, value: string, options?: object): void` - Sets a cookie
