A free barcode calorie scanner

Because scanning a barcode costs us nothing. The camera work happens on your phone, the lookup goes straight from your browser to Open Food Facts — an open database, free to read — and your log sits in your own browser storage. There is no per-scan bill arriving at our end, so there is nothing to pass on to you and no honest reason to cap you at five scans a day.

That is the whole rule we run on: free unless it costs us. If we ever build something with a real bill behind it — syncing your log between two phones, say — that thing gets a price and a decision of its own. The scanner does not.

We do not know what you ate. Not because we promise not to look, but because it never arrives: the log is written to storage inside your own browser and there is no account, no server copy and no sync. What you ate is a health fact about you, and the safest place for it is the only place you can delete it from.

We do count how many people open this page and how many log their first product, as one number each, with no food names attached and nothing identifying in them. That is how we find out whether the page works. The barcode lookup goes to Open Food Facts directly from your browser, so they see a request for a product number from your connection — not from us, and with nothing about you attached.

Packaged food comes from Open Food Facts, a database that anyone can read and anyone can correct — the same open project a lot of paid apps quietly read from too. Food with no barcode comes from USDA FoodData Central, which is in the public domain.

Anyone-can-edit cuts both ways, so this page shows you where every number came from and when that record was last touched, and says so plainly when the figures cannot be right: over 900 kcal in 100 g, macros adding up to more than the food weighs, an energy figure that does not match its own protein, carbs and fat. We show the record and the doubt together. We never quietly correct a number and we never quietly hide one.

One screen, one day, a running total. No recipe builder, no meal plans, no streaks, no AI reading your dinner off a photograph, and no syncing between devices. Those are the features that turn a scanner into a subscription, and leaving them out is the point rather than a to-do list.

It will not tell you what to eat either. Put in your own daily figure and the page subtracts; that is arithmetic on a number you chose. It is not a medical device and it does not give advice. If you are counting for a diagnosis, the person treating you sets the numbers, not a web page.
