Each license allows different usage situations. A desktop license will cover the functions of most design work (i.e. making logos, print materials, social media promos, etc.).
A web license is needed when you plan to use and embed the font on a website. You won't need a web license if you create images with the text that you upload to your site – for example, a logo on a website is just fine with a desktop license because it's an image, not editable type.
An e-pub license covers the use for ebooks, so if you wanted to use a font for your chapter titles and publish the book to Kindle or another ebook format, you'll need an e-pub license.
An App license you need, when you'd like to use the font as non-editable text in an app.
Note: this is not a server license, so you cannot use an app license for print-on-demand or customizable design apps (i.e. Canva, Over, etc.).
Yes! Get yourself a desktop license to use this font for your logo or other print designs. If you plan to use the font on your website (outside of a rasterized image or vectorized logo), you need a web license as well.
You'll need as many licenses as users. So if you work at a company where 10 designers on your team will need access to the font, you'll need to purchase 10 of the appropriate license.
