5 Simple Habits to Protect Your Privacy When Using AI

You don't need to become a privacy expert to meaningfully reduce how much of your personal information ends up stored on someone else's server. A handful of consistent habits go a long way — here are five worth building into how you use AI day to day.
1. Treat Every Prompt Like It's Public
The simplest, most effective privacy habit is also the easiest to forget in the moment: don't type anything into an AI chatbot that you wouldn't be comfortable seeing made public. The Office of the Privacy Commissioner of Canada recommends limiting the personal information you share, avoiding sensitive or identifiable details, and never sharing personal information about other people in your conversations (Office of the Privacy Commissioner of Canada).
In practice, this means swapping out real names, addresses, and account numbers for generic placeholders when you're working through something sensitive — describing a situation rather than pasting the actual document that contains it.
2. Skip the "Sign in With Google" Button
When you create an account for a new AI tool, Mozilla Foundation's privacy research recommends avoiding "sign in with" options through Google, Facebook, or other third-party accounts whenever you can, since that link gives the apps a way to exchange information about you behind the scenes (Mozilla Foundation). Signing up with a dedicated email address, ideally one you don't reuse everywhere, keeps that account more isolated from the rest of your digital life. The Privacy Commissioner of Canada adds a similarly simple step: using an alias instead of your real name wherever a tool allows it (Office of the Privacy Commissioner of Canada).
3. Find the Training Toggle and Actually Use It
Most major AI chatbots have a setting that controls whether your conversations get used to train future versions of the model. It's rarely the first thing you see, and it's rarely set in the direction you'd want by default. Take a few minutes the first time you use a new tool to find this setting, usually somewhere under "Data Controls," and decide deliberately rather than by accident.
It's also worth periodically deleting old conversations you no longer need rather than letting months or years of chat history accumulate in one place (Mozilla Foundation).
4. Use Temporary or Incognito-Style Modes for Sensitive Topics
Many AI tools now offer a temporary chat mode that behaves differently from your regular conversation history: it isn't saved long-term and isn't used to train the model. OpenAI's version, Temporary Chat, automatically deletes those conversations from its systems within 30 days even if you never go back to delete them yourself (OpenAI Help Center).
Save this mode specifically for the conversations that matter most: health questions, financial decisions, anything involving another person's private information, or a creative project you're not ready to share. It's a small habit, but it's the one that does the most for the exact moments where privacy matters most.
5. Know When "Cloud" Isn't the Right Tool for the Job
None of the habits above change one underlying fact: as long as a conversation travels to a company's server, you're trusting that company's policies, security, and judgment with your words. For most everyday questions, that trust is a reasonable trade for convenience. But for genuinely sensitive work — drafts you're protective of, personal details you'd never want exposed, anything you'd consider a real breach of privacy if it leaked — it's worth knowing that AI tools exist which process everything directly on your own device, where the question of "what happens to my data" has a much simpler answer: nothing, because it never left.
The Habit That Ties It Together
None of these five habits require technical expertise. They require about ten minutes of attention the first time you set up a new AI tool, and a moment's pause each time you're about to type something genuinely sensitive. Privacy, in practice, is rarely one big decision — it's a series of small, repeatable ones.
