Analysis runs on your device
When you upload a WhatsApp export, the parsing and the stats happen in your browser. The raw chat is not sent to a server to be analyzed, and it is not saved to an account.
AI features send only anonymized excerpts
For the digest, Ask AI and receipts, short excerpts of the chat are sent to an AI model to generate a response. Names and phone numbers are replaced with placeholders before anything leaves your device, and the excerpts are not retained after the answer comes back.
Files shared from WhatsApp pass through briefly
When you share a chat straight from WhatsApp on Android, the file has to pass through our server for a few seconds so the app can pick it up. It is handed to your device and then deleted. Manual uploads never touch the server at all.
Chat content is never stored on our servers
Your chats, exports and results live only in your own browser, on your device, and you can clear them anytime. Usage is counted per account — how many chats you've saved, drafts you've copied, and so on — so we can improve the app; that's counts only, never chat content.
Ads and measurement
We advertise Chatorizer on Meta (Facebook and Instagram) and Google. To see how those ads perform, we use the Meta Pixel, the Meta Conversions API and Google tags. These record actions like page visits, sign-ups, starting a trial and subscribing, and they may set cookies in your browser. Some of these events — sign-ups and subscriptions — are also reported to Meta from our own server. This measurement never includes your chat content: only that an action happened, not anything from your chats. You can opt out through the cookie choices we offer, by blocking or clearing cookies in your browser settings, and by using Meta's Ad Preferences and Google's Ads Settings to limit ad personalization.
No affiliation with WhatsApp
Chatorizer is an independent tool. It is not made by, endorsed by, or affiliated with WhatsApp or Meta.
