private, URL-powered calendar·hash-calendar.netlify.app

hash-calendar is a privacy-first, client-only calendar that stores all calendar data in the URL hash rather than on a server. Users can create events, share calendars instantly via link or QR code, and optionally password-protect shared calendars. It supports importing/exporting ICS files, a JSON bridge for programmatic access, multiple languages, dark mode, and offline use as a PWA — with no accounts or backend required.
