The short version
We collect as little as we can. We do not ask for health information. We do not store your quiz answers or the numbers you type into calculators, except for the optional weight line described below that you can choose to save. If you choose to save a calculator result to your account, we keep only the result you saved. For the calculators that feed your progress charts, that result can include the weight you entered, shown as a line called “Your weight”, and it is saved only if you leave the box to include it ticked. We do not keep the other numbers you typed, such as height, age, neck, waist or hip. If you choose to set a goal, we keep only the target and optional date you enter. If you choose to log calories in your food diary or set a calorie target, we keep only the numbers you enter, and any target is a number you choose, not a recommendation from us. If you use the optional weigh-in, body measurement or activity logs in your journal, we keep only what you enter there. You can delete results and goals at any time. If you tick “Remember my numbers on this device” on a calculator, those numbers are kept only in your own browser and are never sent to us; you can remove them at any time. We do not sell your personal information.
What we collect
- If you create an account: your email address, the date you agreed to our terms, whether you chose the optional weekly digest, the articles you save to your library, any calculator results you choose to save (shown only in your private journal), any goals you choose to set (a target number and an optional target date), and any journal entries you choose to write (the date, an optional mood and topic tags, the text you write, and an optional food and water diary of what you choose to type, including optional calories for each meal), and any calorie target you choose to set (a number for each day of the week you choose, with the weekly total worked out from them), and any optional weigh-ins, body measurements, activity entries (minutes and steps), favorite meals, nutrition numbers added from the Food lookup, and hunger and fullness check-ins, and progress photos (with an optional date and caption) you choose to record.
- If you subscribe to our newsletter: your email address, handled by our email service provider.
- When you visit: basic usage information such as pages viewed, device and browser type, and approximate location, collected through analytics and cookies.
The calculators and reading-list quiz
Calculators run in your browser. If you choose Save or Email on a result, the results shown (including the “Your weight” line unless you untick it, but not your other measurements) are sent to our server so we can store or email them for you. The quiz uses your answers only to build your results at that moment and does not save them on our servers. If you have an account, we remember only that you took the quiz and the date, never your answers, so your library does not keep offering it. If you leave to create an account, your answers may be held temporarily in your own browser so we can finish building your list when you return. We clear them after use. Links you share from the quiz leave out health-related answers and body measurements.
Food lookup
The Food lookup page lets you search nutrition facts. What you type is sent from our server (not your browser) to USDA FoodData Central and Open Food Facts to find matches, so those services do not see your address or account. If you use Scan a barcode, the camera is used only on your own device to read the number, we never receive or save a picture, and only the number is looked up. The same is true if you photograph a nutrition label: the photo is read by software that runs in your browser, it is never uploaded, and it disappears when you leave or discard the entry; only the numbers you choose to keep (and add to your diary or save) are stored. We do not save your searches to your account. Results are kept briefly so repeat searches are faster, and we count requests per visitor to prevent abuse. If you have an account you can also save foods and build recipes; we keep the food names, nutrition numbers and amounts you choose to save, only for you, and delete them when you delete them or delete your account. If you choose Add to diary, a line of text and the calories for that food are added to the meal you choose in your private journal.
Your private journal
The journal, including its optional food and water diary, optional calories per meal, optional calorie target and weekly look-back, is optional. Entries are stored on our site and tied to your account only. They can be seen only by you, when you are signed in. We do not use journal entries for advertising or analytics, we do not put them in emails, the journal page shows no ads, and search engines are told not to index it. Entries are included in our routine site backups, and our hosting provider stores the site’s data on our behalf. You can edit or delete any entry, download all of your entries, or delete them all at any time. Deleting your account deletes your journal, your calorie target, your weigh-ins, body measurements, activity entries, favorite meals, progress photos and your saved foods and recipes. The journal is not medical or mental health advice and is not a substitute for professional care.
Calories you log are numbers you type yourself, or numbers added from the Food lookup, and they are estimates. We add them up by meal, day and week (Monday through Sunday) only for you, on your journal page. A calorie target is a number you choose; we do not suggest one, and it is not medical advice. Calories and targets are health-related, so we treat them like your journal entries: only you can see them when you are signed in, we do not use them for advertising or analytics, and we do not share them. You can change or remove your target and edit or delete your calories at any time.
Your journal also has optional tools: weigh-ins (with a smoothed trend line worked out from them), body measurements, an activity log of minutes and steps, favorite meals, protein, carbohydrate, fat and fiber numbers added from the Food lookup, and hunger and fullness check-ins. Weight and body measurements are health-related. We keep these only on our site, tied to your account, shown only to you when you are signed in, never used for advertising or analytics, and never shared. You can remove any entry, delete everything in a tool, or delete your account to remove them all. We do not estimate calories burned, and none of these tools is medical advice.
You can also add optional progress photos to your journal. A photo is shown only to you, when you are signed in. We store it on our server in a private folder that is not part of the public media library, we resize it and remove hidden data such as camera and location details, and we never use photos for advertising, analytics or emails, and never share them. Please add only photos of yourself or your own meals. Each person can store a limited number of photos. You can delete any photo, or all of them, at any time, and deleting your account deletes them. Photos may remain in our hosting provider’s routine server backups for a short time after you delete them.
