Definition - What does Terms of Service (ToS) mean?
Terms of service (ToS) is a commonly used phrase for the set of rules and regulations a provider attaches to a software service or Web-delivered product.

Techopedia explains Terms of Service (ToS)
A terms-of-service agreement is similar to an end-user licensing agreement (EULA) for licensed software. The difference is that, instead of licensed out-of-the-box software products, users are utilizing a service, hence the adjusted terminology. Users can encounter terms of service on all kinds of software, from word processors and graphic design programs, to advanced industry software or statistical software services.
Elements of a ToS agreement can include privacy policies, accountability provisions, opt-out provisions and liability provisions. Some may set up arbitration for any user grievances. Many of them lay out a list of what users cannot do on a particular service, for example, post objectionable content, utilize services for specific commercial purposes, etc. In general, a ToS agreement serves to set up a foundational contract between the user and the service provider.
