Every time you type something into ChatGPT, you're sharing information. Maybe it's a coding question. Maybe it's a health concern. Maybe it's a private document you uploaded for analysis.
Here's what most people don't realize: by default, many AI companies use your conversations to train their models. Some keep that data indefinitely. Some share it with advertisers.
That's not a reason to stop using AI. But it is a reason to understand what you're sharing and how to control it.
Let's walk through the practical steps.
What Gets Collected
When you use an AI chatbot, companies may collect:
Your conversation history
Personal details you mention (names, locations, health concerns)
Files and images you upload
Your IP address and device information
Feedback you give (thumbs up/down)
Account information if you're signed in
The trend is toward more data collection, not less. One company announced a feature that lets its AI remember what apps and websites you use. Another said it will use photos you upload through Search to train its AI, unless you opt out.
The upside is more useful, personalized AI. The trade-off is giving companies a broader view of your life.
Step 1: Turn Off Model Training
This is the single most important step.
By default, most AI companies use your conversations to train their models. You can turn this off.
ChatGPT: Go to Settings > Data Controls. Find "Improve the model for everyone." Turn it off. Your future conversations won't be used to train OpenAI's models.
Google Gemini: Go to Gemini Apps Activity. Turn off "Keep Activity." Your future chats won't appear in your activity and won't be used to train Google's AI models.
The trade-off: disabling activity also changes how Gemini works. You'll lose saved chat history, and some personalized features disappear.
Claude: Go to Settings > Privacy. Find "Improve Claude for everyone." Turn it off.
Other platforms: Microsoft Copilot, Meta AI, and Grok all have varying privacy controls. Some are easy to find. Others are buried.
Step 2: Use Temporary Chats for Sensitive Topics
Most major AI platforms now offer a temporary chat mode. Conversations here aren't saved, aren't used to create memories, and aren't used for training.
How to use it: In ChatGPT, click the circular "Turn on Temporary Chat" icon at the top right of the chat window. The prompt field changes appearance to show you're in temporary mode.
When to use it:
Health questions
Financial concerns
Personal relationship issues
Anything you wouldn't want stored
What it doesn't do: It doesn't make you completely anonymous. The company may still see the conversation to give you a response. But it is not going to be saved or used for training.
Step 3: Do Not Sign In Using Google or Microsoft
When signing up for an account, you may sign in using your email or through single sign-on using Google, Apple, or Microsoft.
Do not use Google or Microsoft accounts. Some data is shared.
Apple is a better choice, but only if you use "Hide My Email." That keeps your Apple account anonymous.
The safest option: sign up with your own email and a strong, unique password.
Step 4: Review your Memory Settings
There are some AI platforms which allow memory features which remembers personal information through conversations. It results in a personal response from the AI platform but also builds a profile about you.
Where to find it:
Platform | Location |
ChatGPT | Settings > Personalization > Memory |
Gemini | Gemini Apps Activity |
Claude | Settings > Privacy |
If you don't want AI remembering things about you, turn memory off.
Step 5: Delete Your Conversation History
Even if you've turned off training, your conversations may still be stored. You can delete them.
What should you do?
ChatGPT: Settings > Data Controls > Clear Chat History
Gemini: Gemini Apps Activity > Review & Remove Your Activities
Claude: Delete conversation histories from Settings page
Some companies retain your data indefinitely. Frequent deletions decrease the period for which your data is stored.
Step 6: Turn On Multi-Factor Authentication
This doesn't protect your data from the AI company. It protects your account from being accessed by someone else.
If someone gets into your AI account, they can see your conversation history. It may be holding some sensitive data.
How to activate:
ChatGPT: Settings > Security > Two-factor authentication
Others: Check your account’s security settings.
Avoid using SMS, and use an authenticator app instead.
Step 7: Handle What You Upload with Caution
Uploading files is one of the biggest threats. Businesses can use uploaded files to train their systems, even sensitive information contained in them.
Things to avoid uploading:
Files containing any ID numbers
Financial data (bank statements, tax information)
Medical files
Legal documents containing sensitive information
Anything you wouldn’t want to keep forever
What's usually safe:
Code snippets (without credentials)
Public data
Generic examples
Documents you've already published publicly
Platform Privacy Comparison

ChatGPT | Yes | Yes | Yes | Review and delete |
Gemini | Yes | Limited | Activity-based | Auto-delete 18 months default |
Claude | Yes | Not available | Limited | Review and delete |
Copilot | Yes | Limited | Yes | Review and delete |
Meta AI | Limited | Incognito mode | Activity-based | Varies |
For Businesses
If you're using AI tools for work, individual privacy settings aren't enough. An organized process is needed by organizations.
Use business accounts. These tend to provide better protection. OpenAI, for example, doesn't train on inputs or outputs from business users by default.
If your team is using personal accounts for work, that's a data governance problem.
Set usage guidelines. The following should be formalized:
Authorized AI tools
Data that can be shared
Data that cannot be shared
Safeguards for handling sensitive data
Data classification. Apply data classification, minimization, and role-based access control mechanisms to reduce access privileges of models. Use anonymization and encryption as the default practices.
Monitor and Audit. Log audits of all the data being input and output of AI systems. This helps in the auditing process and also proves that data governance is an ongoing process.
Regulatory Environment
AI privacy regulations are quickly evolving.
The EU has passed the Digital Omnibus Package with proposals for amending the GDPR to ease compliance and establish clear legal grounds for using AI with data.
It appears that the EU AI Act, the GDPR data minimization requirements, and U.S. regulations seem to converge. Those who operate in multiple regions should take compliance seriously.
In practical terms, individuals should be aware that their data is being collected and take action to control it.
The Bottom Line
Protecting your data when using AI isn't complicated, but it does require action.
The default settings on most platforms favor data collection. You have to actively opt out of training, use temporary chats for sensitive topics, and be mindful of what you share.
Take ten minutes today to review your privacy settings. Turn off training. Clear your history. Be intentional about what you type.
Your data is yours. These steps help you keep it that way.

Do AI companies train on my conversations by default?
Yes. Most major AI companies use user chat data by default to train their models. You need to actively opt out.
Can I use AI without creating an account?
Yes. There is no need for signing in to use ChatGPT. You get a basic version without advanced features.
What happens if I turn off model training?
Your future conversations won't be used to train the company's models. Data already used in training can't be recalled. The setting only affects future data.
Is Temporary Chat completely private?
No. The company may still see the conversation to give you a response. But it won’t be saved or used for training purposes.
What AI platform is the most private?
ChatGPT and Claude are privacy-respecting AI platforms. They have an option to opt out of their training, and you can also delete your history.
