AI and privacy: how to protect your data

4 golden rules for using AI safely:

1. Never paste: passwords, credit card numbers, medical data, work secrets
2. Disable training in the settings (all chatbots offer this option)
3. Prefer Team/Enterprise versions for pro use (GDPR commitments)
4. Anonymize sensitive data before submitting

For truly critical cases: open source models running locally (Mistral, Llama, DeepSeek) — your data never leaves your computer.
