No Logs, No Access — Not Even for Meta
According to Zuckerberg, Incognito Chat stores no conversation history on Meta's servers and applies end-to-end encryption throughout. The company says it cannot read the messages itself. All AI responses are processed inside a Trusted Execution Environment — a secure, isolated computing space that prevents external access, including by Meta's own engineers.
"To get the most out of a personal superintelligence, we all need to be able to discuss sensitive topics without anyone being able to access that conversation," Zuckerberg wrote. "I'm proud that Meta is the first lab to offer private AI."
The implicit target of that claim is the rest of the industry. Google retains data from temporary Gemini sessions for up to 72 hours. OpenAI keeps ChatGPT conversation logs for up to 30 days. Anthropic's Claude retains data for at least a month. Incognito Chat, by contrast, is built on Private Processing — a technology Meta introduced for WhatsApp in 2025 — and is set to roll out to users in the coming months.
Meanwhile, ChatGPT Logs Are Showing Up in Court
The announcement arrives as OpenAI finds itself entangled in a growing number of legal disputes directly involving ChatGPT conversation records. Logs from the chatbot were cited in lawsuits connected to two mass shooting cases — one in Tumbler Ridge, Canada, and another at Florida State University — with plaintiffs alleging that OpenAI ignored warning signs in the shooters' messages.
Now the company faces a fresh lawsuit in California. The parents of a 19-year-old who died of a drug overdose last year allege that ChatGPT provided their son with advice on combining dangerous substances. Leila Turner-Scott and Angus Scott claim their son Sam Nelson used the chatbot to seek guidance on mixing different drugs, and are holding OpenAI and its leadership responsible for the outcome.
The timing of Meta's Incognito Chat launch — emphasizing privacy and zero retention — appears unlikely to be coincidental
