WhatsApp Chat Stats is a free, client-side tool. All chat processing happens entirely in your browser. We never upload, store, or access your chat data on any server.
Your WhatsApp export file is processed locally using JavaScript in your browser. The data is stored temporarily in sessionStorage (cleared when you close the tab). We have no ability to see, collect, or transmit your messages.
We use Google Analytics and Google Ads tags to understand site traffic and measure ad effectiveness. These may set cookies in your browser. No personal chat data is ever included in analytics.
