About this app

SiCal is a private calendar app built on the decentralized Sia network. Create, organize, and manage your schedule without relying on a traditional central server or account-based calendar platform.

With SiCal, you can create and edit events, manage multiple calendars, import calendar files like ICS, and stay on top of your schedule with event reminders and alerts. Your calendar data is tied to your recovery phrase, giving you a portable way to restore access and keep control of your information.

Key features:
-Decentralized calendar storage powered by Sia
-Create, edit, and organize events across calendars
-Import existing calendar files including ICS
-Event reminders and alerts
-Sync support to keep your calendar up to date
-Restore access with your recovery phrase
-No traditional account required
-SiCal is designed for people who want a calendar that is practical, mobile-friendly, and more aligned with user ownership and privacy.

This app was funded by a grant from the Sia Foundation.
