在小程序开发过程中，我们需要嵌入字体 DIN-1451，出于不侵犯字体版权公司的考虑，我们决定购买该字体的版权，请问：小程序嵌入字体时，应该购买该字体哪种类型的授权？

我在字体版权售卖网站Fonts.com中查阅到有以下三种比较贴近的授权模式：WEB字体许可授权（LICENSES FOR REGULAR WEB FONTS）、移动应用字体授权（LICENSES FOR MOBILE APPS）和服务器许可授权（SERVER LICENSES），原文链接：https://www.fonts.com/font/linotype/din-1451/licenses#

三种授权协议原文如下： 点击进入原文页面

LICENSES FOR REGULAR WEB FONTS

Available in "Pay as you go" or "Pay once" models

Web fonts are licensed for use on websites in accordance with the conditions of the CSS@font face declaration. The Web fonts that can be acquired from Linotype.com are supported by all major browsers, including Firefox 3.5+, IE 5+, Opera 10+, Chrome 4+, Safari 3.1+, iOS Mobile Safari, Android 2.2+ and BlackBerry OS 6.

LICENSES FOR MOBILE APPS

A mobile app license permits the embedding of a font into the iOS, Android or Windows Phone mobile platforms for a single title and a set number of app installations. You can view and modify the installation limit from the cart. App installations can be spread out across the platforms your app is available for. A new license is not required to cover updates to an app, however installations of newer versions of your app do count toward your installation limit. 

SERVER LICENSES

Server licenses authorize the installation of a font on a server that is accessed by remote users or website visitors. These licenses are commonly used by Web-based businesses providing goods that are personalized by its users such as business cards, images with captions and personalized merchandise. Users are not allowed to download the font file and the font may not be used outside the server environment. The font may not be employed for a software as a service (SaaS) application in which the service is the actual product and not the means of providing the product. Server licenses cover a set number of CPU cores on production servers (development servers are not counted) on which the font is installed. The license is valid for 1 year.

服务器许可证

服务器许可证授权在远程用户或网站访问者访问的服务器上安装字体。这些许可证通常由基于Web的企业使用，提供由其用户个性化的商品，例如名片，带有字幕的图像和个性化商品。不允许用户下载字体文件，并且不得在服务器环境之外使用该字体。该字体不能用于软件即服务（SaaS）应用程序，其中服务是实际产品而不是提供产品的方式。服务器许可证涵盖了安装字体的生产服务器（不计算开发服务器）上的一定数量的CPU核心。许可证有效期为1年。了解更多…
