ChatGPT & Claude (MCP)
How to Stop ChatGPT From Training on Your Data
By default, everything you type into ChatGPT can be used by OpenAI to train its models. It is one setting to change and takes about 20 seconds. On desktop, click your name in the left corner of the screen, then Settings. On mobile, tap the menu in the top left, then Settings. Open Data controls and, at the very top, turn off Improve the model for everyone. Once that toggle is off, OpenAI does not use your conversations to train its models. Your chats still work the same and your history stays where it was. It matters if you paste real things into ChatGPT: client emails, draft contracts, notes from calls. The setting is per account, so check each account you use. On ChatGPT Team and Enterprise plans training on your data is already off, so this is mainly for Free and Plus accounts. Claude has the same default and a matching fix.
Step by step
- 01
Open Settings
On desktop, click your name in the left corner of the screen, then Settings. On mobile, tap the menu in the top left of the screen, then Settings.
- 02
Open Data controls
Data controls is the section that holds everything about how OpenAI uses your conversations.
- 03
Turn off Improve the model for everyone
It is the very first toggle at the top of Data controls. Switch it off. From here on OpenAI does not use your conversations to train its models. Your chats still work exactly the same, and your history stays where it was.
- 04
Check every account you use
This is a per-account setting, so a personal account and a work account each need the toggle flipped. Team and Enterprise plans already have training off, so this mainly applies to Free and Plus.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
