About hash-calendar
Last updated: February 12, 2026
Project Purpose
hash-calendar is a privacy-first, client-only calendar designed for fast sharing without accounts. It keeps calendar state in the URL hash so you can share a schedule by sharing a link.
Trust Signals
- No account required.
- No server-side calendar database.
- URL hash data is not sent in standard HTTP requests.
- Optional password-based encrypted links are supported.
- Privacy-first app under the MIT license.
This app is intended for convenience and privacy, but shared links are still sensitive. Treat calendar links like private data.
