How to Stop AI Chatbots From Using Your Chats for Training

You can limit whether consumer AI services use your conversations to improve or train models, but a single switch does not erase every copy of your data or guarantee that no processing will occur. Training controls, chat history, memory, feedback, abuse monitoring, legal retention, and account deletion are separate issues.

The safest rule is still to avoid entering passwords, financial account details, private medical records, confidential business files, or other information you would not want stored on a third-party service. The steps below focus on personal consumer accounts; work, school, enterprise, and API products may follow different data policies.

What an AI training opt-out usually changes

Turning off a model-improvement setting generally stops eligible future conversations from being used in future training. It may not remove information from models already trained or from a training run already in progress. Providers may also retain limited data for security, legal, or abuse-prevention purposes.

Deleting a chat is a separate action. If you want to reduce stored history as well as future training use, review both the training control and the service's delete or auto-delete options.

Gemini: turn off or delete Gemini Apps Activity

1. Open Gemini and sign in to the Google account you use with the service.
2. On the web, open the menu and choose Settings & help, then Activity. In the mobile app, open the menu, select your profile picture or initial, and choose Gemini Apps Activity.
3. Near the top of the activity page, select the current activity status.
4. Choose Turn off or Turn off and delete activity, then review the notice before confirming.

Turning activity off and deleting existing activity are not the same operation. Google also provides separate controls for whether audio, Gemini Live video, and screen-sharing data can help improve its services. Review those options if you use voice or live features. See Google's Gemini Apps Activity instructions for the current menu labels and retention choices.

Claude: disable model improvement

1. Open your Claude consumer account and select your name or profile menu.
2. Choose Settings, then Privacy.
3. Turn off Help Improve our AI models.

Anthropic says that after this control is turned off, it will not use your previous or new consumer chats and coding sessions in future model-training runs. Data already included in training underway or in completed models is not removed. Safety-flagged conversations and feedback can be handled under separate rules.

For a conversation you do not want used for model improvement, Claude's Incognito chat is another option. Anthropic says Incognito chats are not used to improve Claude even when model improvement is enabled. Confirm the current behavior in Anthropic's model improvement privacy guide.

ChatGPT: turn off “Improve the model for everyone”

1. On the ChatGPT website, select your profile icon and open Settings. In the mobile app, open the sidebar and tap your profile icon.
2. Select Data Controls.
3. Turn off Improve the model for everyone.

Your regular conversations can remain in chat history after this setting is disabled, but OpenAI says they will not be used to train ChatGPT. The setting applies to the account rather than only the device on which you changed it.

For a conversation that should not appear in history or create memories, start a Temporary Chat. OpenAI says Temporary Chats are not used for model training and are deleted from its systems after 30 days, though they may be reviewed for abuse monitoring. The ChatGPT Data Controls FAQ contains the current web and mobile steps.

Grok on X: change data sharing and personalization

1. Open X settings and select Privacy and safety.
2. Scroll to Data sharing and personalization.
3. Open Grok & Third-party Collaborators.
4. Under Data Sharing, deselect the option that allows public data and Grok interactions, inputs, and results to be used for training and fine-tuning.

Training and personalization are separate controls. Review the Grok personalization setting if you do not want X to use your data and interactions to personalize the experience. X also provides a control for deleting Grok conversation history; it says deleted conversations are removed from its systems within 30 days unless retention is required for security or legal reasons. Check X's official Grok privacy instructions for the current options.

What about Meta AI, Facebook, and Instagram?

Meta's use of public information and AI interactions is not controlled by one universal “disable Meta AI” switch. Available objection forms and privacy controls can differ by product, account, and region. Making a social profile private can reduce future public exposure, but it should not be described as a guaranteed or retroactive model-training opt-out.

Review the AI privacy notice shown in your Facebook or Instagram account and use any objection or data-rights process offered for your region. If your goal is to protect a specific photo or personal detail, remove public visibility as well as reviewing the AI controls.

Additional privacy steps worth taking

• Delete old chats separately: An opt-out normally does not automatically clear conversation history.
• Review memory: If the service has a memory feature, inspect and delete saved memories independently of chat deletion.
• Check connected apps: Disconnect services you no longer use and review what data each connection can access.
• Be careful with feedback: A thumbs-up, thumbs-down, bug report, or support request may be governed by a separate data-use and retention policy.
• Recheck settings after major updates: Menu names and available controls can change.

No privacy setting makes it safe to paste secrets into a consumer chatbot. Use the available opt-outs, temporary or incognito modes, and deletion controls as layers of protection—not as a substitute for limiting the data you share.
