You are responsible for making sure that the font software is used in compliance with the End User License Agreement. However, the font data is protected from tampering and theft in a number of ways. Font requests must include a qualified project ID and originate from a qualified domain. Font file names are obfuscated. When possible, fonts will be delivered in EOT or WOFF formats. When appropriate, font files are represented as Base64 encoded strings. At the conclusion of a users visit to your website, the fonts are removed from their browsers temporary cache.
