Microsoft's Services are not for use by children under the age of 13. If you are under 13, please do not use the Services. If you are between the ages of 13 and 18 (or the age of legal majority in your jurisdiction), you may only use the Services under the supervision of a parent or legal guardian who agrees to be bound by these Terms.
This age restriction is legally significant under COPPA and affects how families set up Microsoft accounts for children — if a child under 13 uses the services without proper parental consent setup, Microsoft is not liable for any resulting data collection or harms.
This agreement significantly affects consumers by requiring US-based users to resolve disputes through binding arbitration rather than in court unless they actively opt out within 30 days, eliminating class action rights for those who miss the deadline. Microsoft retains broad rights to modify, suspend, or terminate services and accounts without prior notice in many circumstances, and acquires a wide license to use content users submit through its services. You can opt out of the arbitration clause by sending a written notice to Microsoft Corporation, ATTN: CELA Arbitration Opt-Out, One Microsoft Way, Redmond, WA 98052 within 30 days of first accepting the agreement.
