Many users occasionally hand their phone to a family member, child, friend, or colleague so they can ask ChatGPT a quick question. While the app itself can be protected by the phone’s lock screen, there is currently no way to protect specific conversations containing sensitive personal, medical, financial, or work-related information.

Please add the ability to:

• Lock individual chats with Face ID, Touch ID, or a PIN.
• Move sensitive chats into a protected folder.
• Optionally hide locked chats from the main conversation list until authenticated.

This would significantly improve privacy without making the app harder to use.
