Did you know?

Every time you use an AI chat, you might be sharing more than you think.

When you ask ChatGPT a health question, your symptoms, medications, and insurance details are stored on external servers — potentially forever.

When you paste code with API keys, those keys can be leaked, cloned, or used to rack up charges on your accounts.

When you share someone else's data — a colleague's email, a client's phone number — you're exposing their privacy without consent.
