The details
Your order page is your key
After you send an order you land on its page. Save that link: it is the only key to your downloads and it works on any device. Anyone with the link can download the files, so keep it private.
Downloads
Each file in a paid order can be downloaded 5 times. Each download link works for 15 minutes; open the order page again for a new one.
Using the files
You can use what you buy in your own apps, websites and marketing. You may not resell, share or publish the files themselves, alone or in packs.
