What proton.ch does

Proton AG, founded in 2014 and headquartered in Plan-les-Ouates in the Geneva area of Switzerland, operates a privacy-focused software ecosystem for individuals, prosumers, and organizations. Its products include Proton Mail, VPN, Drive, Docs, Sheets, Calendar, Pass, Authenticator, Meet, Wallet, and Lumo AI, supplemented by the Simple Login and Standard Notes services. The platform uses end-to-end and zero-access encryption across core applications, which are open source and independently audited; its nonprofit primary shareholder, the Proton Foundation, is also part of its governance and community-oriented structure.

Proton uses a freemium, product-led model in which consumers can create free accounts and self-upgrade to paid personal subscriptions, while organizations purchase annual business plans with administration, user-management, and compliance capabilities. Services are distributed globally through web, iOS, Android, macOS, Windows, Linux, browser extensions, smart-TV applications, and command-line tools, with an additional direct business-sales motion. Proton reports more than 100 million total sign-ups and over 100,000 business customers, and generates revenue only from subscriptions rather than advertising or user-data sales.
