TIP: Your AI assistant remembers everything you type to it. Here is what that actually means for your data and what to do about it.

Most people use Claude, ChatGPT, or Gemini as if they are having a private conversation. The reality is more complicated. By default, conversations may be used to improve models, stored for extended periods, and potentially accessible to company employees for safety review. The data you type into a consumer AI interface is not private in the way a personal diary is private.

What to actually do: read the data retention settings for whichever service you use. Claude and ChatGPT both have options to turn off conversation history and training use. Check them. Do not type passwords, financial account details, medical information you would not share publicly, or confidential work materials into any consumer AI interface without understanding the terms. Use the API with logging disabled if you have sensitive professional use cases. Run a local model for anything genuinely private

Turning off training data use and conversation history in Claude settings is four clicks. Most users have never looked at it

The professional liability angle matters. A lawyer or doctor who pastes client information into a consumer AI service may be breaching confidentiality obligations regardless of what the AI company does with the data

Local models are the actual privacy-preserving answer for sensitive work. Ollama running Qwen or Llama on your own hardware with no network calls is genuinely private in a way that consumer AI is not

Enterprise tiers of Claude and ChatGPT have different data retention and training terms than consumer tiers. If your company is paying enterprise rates check what data protections you actually have
