HBO Max is a US service operated by Home Box Office, Inc. in New York. It belonged to Warner Bros. Discovery; according to press reports from October 2026, Paramount has since completed its takeover of Warner Bros. Discovery, which places HBO Max under a US media group. It is proprietary software with no open-source component. For a European organisation or individual, this means account data and viewing behaviour are processed by a US party that is subject to US law, including the CLOUD Act.
