EverydayTurn off AI training and clean up your history
After this you'll be able to:
- find the training switch in each app
- use a private chat for sensitive questions
- run a 5-minute monthly checkup
Find the training switch
On personal accounts, many AI apps may use your chats to improve their models unless you turn it off. Turning it off usually affects new chats only.
| App | Where |
|---|---|
| Grok | Settings → Data (web) or Data Controls (app) → turn off “Improve the model”; or use Private Chat Grok help1 |
| Claude | Settings → Privacy → turn off “Help Improve our AI models” Claude help2 |
| Gemini | Gemini → Settings & help → Activity → turn off Keep Activity Gemini help3 |
| ChatGPT | Settings → Data Controls → turn off “Improve the model for everyone” ChatGPT help4 |
| Copilot | Older Copilot app: profile → Privacy → turn off “Training on conversation activity” and “Training on voice conversations”. Microsoft moved settings in the new app (Aug 18, 2026); check its privacy page Copilot help5 |
Use a private chat for one-offs
Grok's Private Chat isn't saved to your history or used for training. 1 Other apps have similar temporary or incognito chats, but they're still stored for a while.
Check what it remembers
Memory can bring a detail back in an unrelated chat. Read and delete what you don't want kept. In Copilot you can ask "What do you know about me?" or say "Forget that…". 5
Your 5-minute monthly checkup
- Training switch set the way you want, in every app you use.
- Memory: delete anything about other people or your kids.
- Old chats with personal details: delete them.
- Connected apps you haven't used in a month: disconnect them.
