The Terms of Service Agreement is mainly used for legal purposes by companies which provide software or services, such as web browsers, e-commerce, web search engines, social media, and transport services.
A legitimate terms-of-service agreement is legally binding and may be subject to change. Companies can enforce the terms by refusing service. Customers can enforce by filing a lawsuit or arbitration case if they can show they were actually harmed by a breach of the terms.
