Data License: Use Our Numbers

Take the data. Take the charts. Build something with them. Just say where they came from and link back.

Page last updated July 26, 2026.

We spend a lot of time pulling USDA nutrition values, checking shelf prices, and re-auditing rows that don't look right. Then we publish all of it as plain CSV files anyone can download. That's the whole point. Data nobody can check isn't evidence, it's a claim.

So here's the deal, in plain language before the legal version.

The license

Every data file in our public data directory and every chart image we publish is released under the Creative Commons Attribution 4.0 International License (CC BY 4.0).

That's the standard open license used by governments, research institutions, and Wikipedia. Nothing custom, nothing weird, nothing you need a lawyer to read. If you've handled CC BY content before, you already know what to do here.

What you're allowed to do

You also don't need our permission first. The license already granted it. If you want to tell us what you built, we'd genuinely like to see it, but that's a courtesy and not a requirement.

The one condition

Credit Daily Life Hacks, and make the credit a working link. Point it at the specific study page you took the numbers from, or at https://www.daily-life-hacks.com/data/ if you used several datasets or you're crediting the collection as a whole.

The link matters more than the wording. A credit your readers can't follow doesn't let them check the methodology, and checking the methodology is the reason we publish any of this. Put the credit near the chart or table it belongs to, not buried in a footer twelve screens down.

If you changed the data, say so. Something like "adapted from Daily Life Hacks" or "prices converted to euros" is enough. We're not going to argue about phrasing. We just don't want a number we never published attributed to us.

Copy-paste attribution

Grab whichever one fits where you're publishing. Swap the study URL for the specific page you used.

How to cite one specific dataset

Every study ships its own CSV, and each file has a stable name and a permanent URL under /data/. Cite the file, not a screenshot of it. The directory also carries a datapackage.json that lists every dataset, every column, and what each column means, so you can document exactly which version of which file you used.

Format the citation as: Daily Life Hacks, dataset name, year, direct CSV URL, CC BY 4.0. For example, the protein ranking lives at /data/protein-per-dollar-2026.csv and the fiber ranking at /data/fiber-per-dollar-2026.csv.

Prices move. If your citation needs to survive a re-audit, include the date you downloaded the file. We re-audit prices quarterly and document every correction, and the details of how we do that are on the methodology page.

What this license does not cover

CC BY 4.0 applies to the data files and the charts. That's it. Two things are deliberately outside it:

The line is simple: if it's a number we calculated or a chart we generated from those numbers, it's yours under CC BY 4.0. If it's a sentence we wrote or a picture, it isn't.

One more thing worth being upfront about. The underlying nutrition figures come from USDA FoodData Central and the price figures largely from BLS Average Price data, both US government sources in the public domain. What we're licensing is our selection, our pricing work, our calculations, our arrangement of it all, and the charts. The raw government facts were always free.

No warranty, and one honest caveat

The data is provided as is. We audit hard and we publish corrections in public, but a grocery price snapshot isn't a live feed, and your store won't match ours to the penny. Check anything you're going to publish or make a decision on. If you find an error, tell us and we'll fix it and note the fix.

Nothing here is medical or nutritional advice, and the license doesn't change that. It's cost math on groceries.

Questions about reuse that this page didn't answer? Ask. The whole reason the data is public is so people use it.
