What it does
Proton Calendar is a calendar app available as a web app and as mobile and desktop apps. Proton also describes private scheduling and team calendar features for business users. It may suit people who want a calendar within Proton’s account ecosystem; verify interoperability and plan details if it must coordinate with external services.
Start with a Proton account, then use the Calendar web app or install one of the listed clients. Proton’s product page links to personal and business versions, appointment scheduling, support, and mobile and desktop downloads. A team looking at the business edition can review its team-calendar setup separately from the personal service; the Calendar page is the official overview.
The product page offers account creation for free and presents paid personal and business plans. Its platform list includes web, macOS, Windows, Linux, Android, and iOS. The accessible sources did not establish the full range of external calendar imports or integrations, so confirm that before migrating a calendar collection. No account was created and no event was entered.
