What you can do
You can use any icon on Thridy in commercial work. That covers a client website, a product you charge for, a pitch deck, an advertisement, a printed brochure, an app on a store, a course you sell, a video, a report, and a slide in a presentation somebody paid you to make.
You do not need to ask first, you do not need to buy anything, and you do not need to tell us what you built. Download the PNG and use it.
What we ask in return
On the free plan, credit Thridy somewhere reasonable. A line in a footer, a credits slide, a readme, or an about page is plenty. We are not precise about the wording, only that a reader could find their way back here.
On a paid plan the attribution requirement goes away entirely, which is the main thing people are paying for. If your client has a policy against third party credits, or the design simply has nowhere to put one, that is the version you want.
What you cannot do
You cannot resell the icons as icons. Bundling them into a pack and selling it, uploading them to a stock site, or offering them as a free download elsewhere are all out, because at that point you are competing with the thing you took them from rather than building something with it.
You cannot claim you drew them, and you cannot register them as a trademark. Beyond that, the useful test is simple: if the icon is an ingredient in your work, that is fine. If the icon is the product, it is not.
Why the answer is this short
Most icon licences are long because they are trying to describe a dozen tiers. This one is short because there are two states: credit us, or pay us and do not. Every icon on the site is covered by the same terms, so you never have to check whether the one you picked is the exception.
The full text lives on the licence page if you need something to forward to a legal team, and it says the same thing at greater length.
Questions people actually ask
Can I use these for a client? Yes. The licence follows the icon, not the person who downloaded it, so work you deliver to a client is covered and your client does not need their own account.
Can I edit them? Yes. Recolour them, crop them, composite them, animate them, put them through a filter. A modified icon is still covered by the same terms, and you do not owe us a copy of what you made.
Can I use one in a logo? We would rather you did not, and the reason is for your benefit rather than ours. A logo needs to be exclusively yours to be defensible, and an icon that thousands of other people can download is the opposite of exclusive.
Do I need a licence file? No, but if a procurement process wants one, point them at the licence page. It is a URL that will keep working, which is usually what they are actually asking for.
