Cennik - Price Tracker por Gaigen

Cennik tracks product prices and shows the honest history — so you know whether a “sale” is real.

• Wildberries & Ozon — one-click «Track price» button right on the product page
• Any store — schema.org, microdata, meta tags, SPA state; an eyedropper for tricky sites
• Price history — charts, min/max/average, target price with progress bar
• Alerts — browser notifications + optional Telegram via your own bot token
• Privacy first — no accounts, no cloud, no analytics; everything is stored locally, JSON export included

Some SPA stores are checked by briefly opening a background tab — that's how Cennik reads prices that anti-bot protection hides from plain requests.
