ChatGPT stored what you typed and guessed what you didn't. These 3 prompts show you the whole file, and the steps below clear anything you don't want it holding.
ChatGPT has a memory. It saves details from your conversations, and it fills in the rest on its own: your age range, your income, how you handle stress. Most of it will feel harmless. A few lines will surprise you.
And if you run a business, there's a second layer. Every client email you pasted in, every project note, every name. Pieces of that can be sitting in your profile too, and your clients trusted you with it. This checkup shows you everything in 5 minutes, then you decide what stays.
Everything it has saved about you, in one list. No summary, no highlights, the whole thing.
Lay out everything you've stored and remembered about me as one complete list. Include names, places, work habits, and preferences. Don't summarize and don't leave anything out. I want to see the full file you've built from all of our conversations.
The part nobody expects. What it figured out about you from how you write and what you ask, without you ever saying it.
In this same conversation: now tell me everything you've figured out about me that I never actually said. The things you've guessed from how I write, what I ask, and what I avoid. My age, my income range, how I handle stress. Tell me how confident you are in each guess.
The business owner step. Finds every piece of other people's information sitting in your file: client names, emails, project details.
Search everything you've stored or remembered about me for anything involving other people: client names, email addresses, project details, or anything that came from messages or documents I pasted in. List each item and which conversation it came from.
Claude keeps its privacy controls in one place: Settings, then Privacy. Make sure "Help improve our AI model" is set the way you want it. Off means your conversations stay on your account and aren't used for training. And the same client rule applies anywhere: keep client details inside a project or a chat you control, and tell it what not to keep.
