If you are a Free user you must always attribute the author when using our resources, below you can see the structure of the correct attribution line.
Let's see some examples:
In this link, you can see on the right side of the icon the name Pixel perfect:
http://www.flaticon.com/free-icon/sushi_187463#term=sushi&page=1&position=68
Therefore, the attribution line should be:
"Icon made by Pixel perfect from www.flaticon.com"
This one is made by Freepik, which is our own team:
http://www.flaticon.com/free-icon/sushi_184452#term=sushi&page=1&position=66
The attribution line would follow the same rules:
"Icon made by Freepik from www.flaticon.com"
You need to include one line for each author (not for each icon).
Please note that there are 18 packs created by third parties and therefore not covered by our license:
All packs created by Google: https://www.flaticon.com/authors/google
And this pack: https://www.flaticon.com/autores/dave-gandy
Below you can find a few different scenarios and how the attribution must be inserted for each of them:
Websites:
Insert the attribution on the page where the icon is shown. This can be placed next to the image or on the footer of the website.
Printed products:
Paste this attribution on the final work so the authorship is known (for instance, in the acknowledgements chapter of a book).
Apps/games:
Place the attribution on the app's credits page and on the description page on the app store.
Social Networks:
Insert the attribution line "Icon made by [author link] from @flaticon" (E.g.: Icon made by Freepik from @flaticon) on the post or post comments.
