OpenAI Launches Locked Chats for ChatGPT Privacy
OpenAI announced on October 20, 2026, that ChatGPT users can now lock conversations to keep them private, using a four-digit PIN, Face ID, or Touch ID. The feature is designed for scenarios where users share their device but want to protect sensitive or personal chats. Locked Chats appear in a dedicated section, separate from regular history and search results, and maintain their own memory, preventing new information from leaking into regular chats. The locking does not provide end-to-end encryption or alter data retention practices. The feature is available across various plans, including Free, Plus, Pro, Business, Enterprise, and Edu, but not for Healthcare. The rollout began on October 20, 2026, and may reach users gradually.
OpenAI's introduction of locked chats addresses user privacy concerns, potentially increasing trust and usage of ChatGPT for personal conversations, which could have implications for AI-driven advertising and customer engagement.

OpenAI launches ChatGPT Lockdown Mode for limited users
OpenAI has rolled out a Lockdown Mode for ChatGPT designed to reduce risks such as prompt injection and data exfiltration by limiting the model's interactions with external services. According to OpenAI's support page and reporting by t3n, the feature is being deployed in waves to all users (including free accounts). Lockdown Mode disables web browsing, web-sourced image/file downloads, and features such as Deep Research, Shopping Research and agentic/Agent Mode, while allowing users to continue entering prompts and uploading files locally. The mode can be enabled in Settings → Security (labelled “Sperrmodus” in German) and applies to all chats by default with per-chat overrides. While the setting reduces automated exfiltration via external connectors, it does not prevent manual prompt‑injection attacks via user-supplied uploads or pasted text. Earlier OpenAI messaging noted initial limited availability and admin controls for managed workspaces; this article reports a broader wave rollout.
OpenAI Explains ChatGPT Privacy Protections
OpenAI published a guide explaining what data may be used to train ChatGPT, the safeguards it applies to reduce personal information in training datasets, and the user controls available to opt out. The company says training sources include publicly available content, partner data, and content provided or generated by users, contractors, and researchers. OpenAI describes its OpenAI Privacy Filter, an internal tool that identifies and masks personal information at multiple stages of the training pipeline. The post details user-facing controls: a Settings > Data Controls toggle to disable “Improve the model for everyone,” Temporary Chats (not retained in history and not used for model improvement, deleted after 30 days), and optional Memories that can be reviewed, edited, or turned off. Users can also export data, delete accounts, and submit privacy requests through OpenAI’s privacy portal.
ChatGPT Health: Securely Connecting Your Health Data
OpenAI announced ChatGPT Health, a dedicated ChatGPT experience that lets users securely connect medical records and wellness apps (e.g., Apple Health, Function, MyFitnessPal) to ground health conversations in personal data. Health is designed with layered protections for sensitive data — including purpose-built encryption, isolation, and a separate Health space with distinct memories — and conversations in Health are not used to train OpenAI’s foundation models. OpenAI worked with over 260 physicians across 60 countries and uses an evaluation framework called HealthBench to assess clinical quality and safety. Initial access is being rolled out to a small group of early users (eligible ChatGPT Free, Go, Plus, and Pro plans) outside the EEA, Switzerland, and the UK; some integrations (medical records and certain apps) are initially available only in the U.S.
