Medium is an online publishing platform where authors write and publish articles and blogs. It offers a text editor, organisation of posts by topic, publications that work like shared magazines, and a membership model that gives readers access to paywalled articles. Authors can earn money through its Partner Program. The platform runs entirely as SaaS in the browser and through iOS and Android apps; self-hosting is not possible.
Medium is run by A Medium Corporation, a privately held American company based in San Francisco, founded in 2012. According to a summary of its privacy policy, personal data is processed in the United States and other jurisdictions, with reference to adequacy decisions or standard contractual clauses. The vendor does not name a European storage region. For a European organisation this means US jurisdiction and little control over where data is stored; an own website or a self-hosted CMS offers more control.
