Consumer health data policy

What health information our tools keep, where it comes from, why we use it, who sees it, and how you can see, download or delete it.

What we collect

  • Medicine Tracker: the medicines you list, any notes you add, the times of day you take them, and when you check each one off. Also your time zone, so “today” matches your day.
  • Weight Tracker: your weigh-ins, your goal and your units. If you choose to add them, your height, sex and birth year, used only to show your BMI and body fat estimate.
  • Calorie Tracker: the foods and meals you log, with their calories, protein, carbs, fat and fiber, and your daily calorie goal.

Where it comes from

Only from you: what you type into these tools, or what an AI app you connected adds for you. Your browser tells the Medicine Tracker your time zone. We never buy health information or get it from anyone else.

Why we use it

Only to run the tool you put it in: to show it back to you, keep track of what’s done, and draw your charts and totals. We don’t use it for ads, we don’t sell it, and we never run an AI on it ourselves.

Who it’s shared with

  • Cloudflare, the company that runs our website and stores its data, handles it only to provide that service to us.
  • An AI app, only if you choose. If you connect an AI app like ChatGPT or Claude and tick the Weight Tracker, the company that runs that app sees what you ask it about. That box starts unticked, and your height, sex, birth year, BMI and body fat are never sent. The Medicine Tracker and Calorie Tracker can’t be connected to an AI app.
  • No one else. We don’t sell health information or share it with advertisers or other people, unless the law requires it, such as a court order.

Your choices

  • See and download: every tool has a Your data page where you can download everything you’ve saved.
  • Delete: remove single entries, everything in one tool, or your whole account. Deleted information is gone from the tool right away and from our backups within 30 days.
  • Change your mind: disconnect an AI app, or untick a tool for it, from your account at any time.

Ask us what we hold about you or for help with any of this on the contact page. We answer within 45 days. If we can’t do what you asked, we’ll tell you why, and you can ask us to look again.

If we ever want to use health information for anything not on this page, we’ll ask you first.
