+# Analytics System Implementation
+
+## Обзор
+
+В проект `witlab-app` была добавлена система аналитики на основе Yandex Metrika по аналогии с `witlab-funnel`:
+
+- **Yandex Metrika** - отслеживание просмотров страниц и событий
+- **PageViewTracker** - автоматическая отслежка переходов между страницами
+- **AnalyticsService** - управление параметрами пользователя и событиями
+
+## Структура файлов
+
+```
+src/
+├── components/analytics/
+│   ├── PageViewTracker.tsx       # Отслеживание переходов
+│   ├── YandexMetrika/
+│   │   ├── YandexMetrika.tsx     # Компонент Яндекс Метрики
+│   │   └── index.ts
+│   └── index.ts                  # Экспорты аналитики
+├── providers/
+│   └── analytics-provider.tsx    # Провайдер аналитики
+├── services/analytics/
+│   ├── analyticsService.ts       # Сервис аналитики
+│   └── index.ts
+└── shared/constants/
+    └── analytics.ts              # Константы ID счетчиков
+```
+
+## Конфигурация
+
+### Статичные константы
+
+```typescript
+// src/shared/constants/analytics.ts
+export const YANDEX_METRIKA_ID = "103412914";
+```
+
+## Использование
+
+### Автоматическая отслежка страниц
+
+Система автоматически отслеживает все переходы между страницами через `PageViewTracker`.
+
+### Параметры пользователя
+
+При инициализации система автоматически загружает данные пользователя через `/users/me` и устанавливает параметры в Yandex Metrika:
+
+- `user_id` - ID пользователя
+- `email` - email пользователя  
+- `locale` - язык пользователя
+- `timezone` - часовой пояс
+- `profile_name`, `profile_gender`, `profile_age`, `profile_sign` - данные профиля
+- `partner_gender`, `partner_age`, `partner_sign` - данные партнера
+- `country`, `region`, `city` - геолокация
+
+### Отслеживание событий
+
+```typescript
+import { analyticsService } from "@/services/analytics";
+
+// Отправить событие в Yandex Metrika
+analyticsService.trackEvent("button_click", {
+  button_name: "subscribe_now",
+  screen: "retaining"
+});
+```
+
+### Доступ к данным пользователя
+
+```typescript
+import { analyticsService } from "@/services/analytics";
+
+if (analyticsService.isReady()) {
+  const user = analyticsService.getUser();
+  console.log("Current user:", user);
+}
+```
+
+## Логирование
+
+Система предоставляет детальное логирование в консоли:
+
+```
+✅ [YM] Page View Event Sent
+✅ [Analytics] Service initialized with user data
+✅ [YM] User parameters set
+```
+
+## Интеграция в layout
+
+Компоненты аналитики добавлены в `src/app/[locale]/layout.tsx`:
+
+```tsx
+<YandexMetrika />
+<AnalyticsProvider>
+  {/* ... */}
+  <PageViewTracker />
+  {/* ... */}
+</AnalyticsProvider>
+```
+
+## Отличия от witlab-funnel
+
+1. **Только Yandex Metrika** - без Google Analytics
+2. **Статичный ID** - Яндекс Метрика использует статичный ID вместо динамического из воронки
+3. **Параметры пользователя** - Автоматическая загрузка и установка параметров из `/me`
+4. **Унифицированный сервис** - Единый `AnalyticsService` для управления
+
+## Проверка работы
+
+1. Откройте консоль разработчика в браузере
+2. Перейдите между страницами приложения
+3. Вы увидите сообщения об отправке событий в YM
+4. Проверьте наличие cookies `_ym_uid`
+
+## Совместимость
+
+- ✅ TypeScript
+- ✅ ESLint (без ошибок, только предупреждения о существующих `any`)
+- ✅ Next.js 15
+- ✅ Server-side rendering
+- ✅ Динамические маршруты
