For beginners
Is ChatGPT safe?
Don't paste a card number, a card code, a PIN, or a password. Then turn off training.
This is for a personal account, including the free plan. Not sure where to start? Take the 1-minute quiz.
Don't paste card numbers, card codes, PINs, or passwords
From OpenAI's help on card data, checked October 30, 2026. From OpenAI's help page that says not to paste passwords into the conversation, checked October 30, 2026.
Don't paste a card number, a card code, a PIN, or a password. The short code on a card is a CVV or CVC. Pay on OpenAI's own payment pages, not in the chat.
Turn off training
From OpenAI's data controls page and its page on model training, checked October 30, 2026.
Open Settings, then Data controls, then turn off "Improve the model for everyone."
On a personal Free, Plus, or Pro account, that switch is on until you turn it off. On the website, start from your account menu, and select Done at the end. On a phone, open the sidebar and tap your profile icon to reach Settings. When you are signed in, the switch covers the website and the phone. Your old chats stay. New chats are not used to train the models.
If you are not signed in, open Settings and turn the same switch off. That choice is saved in that browser.
Two catches. If you tap thumbs up or thumbs down, that conversation can still be used for training. During a Daybreak session, what you type can still be used to improve safeguards, even with the switch off. Your other chats still follow the switch. Work and school accounts can differ. Business, Enterprise, and Edu chats are not used for training by default.
Use a temporary chat for anything sensitive
While it stays temporary, it is not used to train the models. It can be kept for up to 30 days. If you save it, it becomes a normal chat and your switch applies.
Email, your phone, and other chat apps are on what to do right now to stay safe.
