Terms of service (also known as terms of use and terms and conditions, commonly abbreviated as TOS or ToS, ToU or T&C) are the legal agreements between a service provider and a person who wants to use that service. The person must agree to abide by the terms of service in order to use the offered service.^[1] Terms of service can also be merely a disclaimer, especially regarding the use of websites. Vague language and lengthy sentences used in these terms of service have caused concerns about customer privacy and raised public awareness in many ways.
