Terms of Service (ToS) is the contract between a company and its users governing how the product or service can be used. Also called Terms of Use or User Agreement, it covers acceptable use rules, intellectual property terms, payment terms, liability limitations, warranty disclaimers, dispute resolution mechanisms (arbitration, governing law), and termination conditions. ToS is the legal foundation of every product-customer relationship and required for any commercial product. It is the document users agree to (often by simply using the product) and that creates the legal relationship.
