 Terms of service (or ToS) are a legal agreement between a service provider and a user of the service. The service may be a website, app, or other software. Generally, the user must agree to ToS before they can access the service. Primarily, ToS protects the service provider and the service from abuse or theft by users. But these terms can also include clauses that secure a user's permission for the service provider to engage in other activities.
 [Third-party ad](https://brave.com/glossary/third-party-ad/)
 A third-party ad is a Web ad whose content is loaded from a different domain than the page showing the ad. The domain is the part of the URL after the "://" and before the next slash. For example, the domain of this page's URL is "brave.com." The opposite of a third-party ad is a first-party ad, which is loaded from the same domain as the page showing the ad.
+[Tokenization](https://brave.com/glossary/tokenization/)
+Tokenization of data is the process of replacing a sensitive data element with a non-sensitive data equivalent, known as a token, that has no meaning or value outside of the specific application it was created for. Tokenization protects sensitive data from unwanted exposure both during transit and while stored, and is thus a well-regarded security measure, meeting compliance standards set by several governing bodies tasked with ensuring data security. Data tokenization has become widely popular, particularly for financial transactions.
 [Tracker](https://brave.com/glossary/tracker/)
 A tracker is a small piece of software, embedded in a website, that records your activity on the site. Trackers send information about the activity they've recorded to a tracking server, owned by the company that made the tracker. Web ads usually include trackers, though you couldn't tell just by looking at an ad. Social media buttons on other sites (such as "Like" buttons) also include trackers. Most trackers are invisible.
