Privacy, Safety & Data Hygiene

Lesson preview

Good AI privacy hygiene comes down to one mental model: assume anything you paste could be seen by the provider, and act accordingly. That means keeping a never-paste list, separating work and personal accounts, knowing your training and memory settings, and thinking about confidentiality before convenience wins the argument. The single most useful privacy habit is a mental model, not a setting: assume anything you paste into an AI tool could, in principle, be seen by the provider — whether through logging, review, or training, depending on your specific plan and settings. This doesn't mean AI companies are reading everything you type; it means you should make decisions as if that were possible, because settings change, mistakes happen, and "probably fine" isn't a great standard for genuinely sensitive information. Once this becomes automatic, most of the rest of this module follows naturally — you start noticing, in the moment, when something you're about to paste crosses a line, instead of realizing it after the fact. A concrete, personal never-paste list turns the abstract mental model into a specific, memorable rule. The core items almost everyone should include: passwords and login credentials, full credit card or ID numbers, and other people's private data you don't have clear permission to share. Writing this list down (literally, on a sticky note or in a notes app) matters more than it sounds like it should — a rule you've consciously written is much easier to recall in the moment than a vague sense that you "probably shouldn't." The list should be short and personal — five items you can actually remember beats a comprehensive twenty-item policy nobody reads twice.

Key terms in this module

AI memory (chat memory)

AI memory is a chatbot feature that carries details from past conversations into new ones, such as your job, preferences or ongoing projects, so you don't have to repeat them. You can usually view, edit or delete what it has stored, or turn it off.

AI training opt-out

AI training opt-out is a privacy setting that stops an AI provider from using your conversations to train its future models. In consumer chat apps it is usually a toggle in the account's data or privacy settings.
