What CC0 actually means for a digital product (and what it does not)

CC0 is the shortest licence in common use and the one most often misread. The deed is a single page, but the gap between what people think it means and what it actually says is where most of the confusion lives. If you sell or buy digital assets, that gap matters.

What the deed actually says

CC0 1.0 Universal is a public-domain dedication. The author waives copyright and related rights to the fullest extent the law allows. Where a waiver is not possible, the deed falls back to an unconditional, irrevocable licence to use the work for any purpose.

• No attribution required. You do not have to credit the author. You may, but the licence does not require it.
• Commercial use allowed. Selling a product that includes the work is permitted.
• Modification allowed. You can edit, remix, and build on it.
• No warranty. The work is provided as-is. The author is not liable for anything that follows from using it.

What it does not do

This is the part people skip.

• It does not grant third-party rights. CC0 covers the author's copyright in the work. It cannot cover a trademark, a person's likeness, or a font that is embedded in a design. If a work depicts something protected by someone else, CC0 does not launder that.
• It does not grant patent rights. The deed explicitly excludes patent and trademark rights.
• It does not prove the work is original. A CC0 label is a promise by the author, not a verification. The licence is only as good as the person applying it.
• It does not let you claim authorship. You can use the work, but you cannot honestly say you created it, and you cannot register it as your own trademark or copyright.
• It does not create exclusivity. Anyone else can use the same work for the same purpose. A competitor can ship the same icon set tomorrow.

Why a small catalogue ships CC0 anyway

Because the alternative is worse for the buyer. A per-seat licence, a seat-count audit, or an attribution requirement creates paperwork for a $6 purchase. CC0 removes the paperwork. The trade-off is real: a CC0 asset cannot be the only thing you sell. It has to be packaged with something the buyer cannot get by copying a file - a preview sheet that saves time, a consistent family that saves design decisions, documentation, updates, and a support address.

That is the actual product. The SVG paths are the raw material.

How to check a licence before you pay

1. Open the licence file inside the download, not just the listing page.
2. Look for the exact identifier: CC0 1.0 Universal, CC BY 4.0, MIT. "Free to use" is not a licence.
3. Check whether the seller claims copyright over the compilation while the individual assets are CC0. That is normal and allowed, but it changes what you can resell.
4. If the asset depicts a person, a logo, or a brand, ask who cleared it. CC0 does not answer that question.

What this catalogue does

Every AEFRI icon set ships with a LICENSE.txt that names CC0 1.0 Universal and links to the deed. The icons are constructed as SVG paths in this repository, not scraped and not generated by an image model. The storefront FAQ states the same thing in the same words.
