AI Privacy: What Happens to Your Data?

Every time you type a prompt into an AI tool, you're potentially sharing information with the company that built it. Understanding what happens to your data is crucial, especially if you're using AI for business or handling sensitive information.

How AI Companies Use Your Data

Most AI companies use your interactions to improve their models by default. This means your conversations may be reviewed by human trainers and used to train future versions of the AI. OpenAI, Google, and Meta all do this to varying degrees.

However, most platforms offer options to opt out of data training. ChatGPT has a toggle in settings, Claude doesn't use free-tier conversations for training, and enterprise plans for all platforms typically exclude data from training.

What to Never Share with AI

Avoid sharing passwords, financial account numbers, social security numbers, confidential business data, and personal health information with AI tools. Even with privacy protections, this data could potentially be exposed through data breaches or model memorization.

For sensitive business work, consider using local AI models (like Llama running on your own hardware) that keep all data on your machine.

Privacy-First AI Tools

Several AI tools prioritize privacy. Anthropic's Claude has strong privacy commitments and doesn't train on user conversations. DuckDuckGo's AI chat routes queries anonymously. Local tools like Ollama let you run AI models entirely on your own computer.
