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. Chat data stays in memory in the current tab and is cleared when you refresh, close the tab, or start a new chat. We have no ability to see, collect, or transmit your messages.
If you accept optional analytics, we load Google Ads, Vercel Analytics, and Speed Insights to understand site traffic and measure ad effectiveness. No personal chat data is ever included in analytics.
