Clubhouse is a social audio app in which people join live voice chats with other users. The product is delivered as a mobile app that users download and sign in to. It is a vendor-operated service, not open-source software. The service is operated by Alpha Exploration Co., which trades as Clubhouse and has a San Francisco address.
The privacy notice names Alpha Exploration Co. as responsible for user information and states that data is stored in the United States, with cloud storage providers based there. Some service providers may be located outside the US and outside the EU or UK. A separate section for data subjects in Europe and the United Kingdom describes the company as controller and refers to standard contractual clauses for transfers. For a European organisation, the US base and US storage mean that the data is subject to US law. No European hosting option is described.
