Family stuff on iCloud. Holidays from some website. Birthdays buried in your contacts. Work on Nextcloud. KashCal brings them together on your Android. No account required, no analytics, no telemetry.

• iCloud: Switched to Android but your family is still on Apple? Sync with iCloud calendars directly. No workaround needed.
• CalDAV: Nextcloud, Radicale, Baïkal, Stalwart, Purelymail, FastMail, Zoho, SOGo, and more. Native sync, no middleware.
• Device calendar: See events from your phone's built-in calendar alongside everything else.
• Holidays & schedules: Subscribe to any ICS calendar. Holidays, school schedules, sports seasons.
• Birthdays: Pulls from your contacts automatically.
• Local: Don't need sync? Works fully offline out of the box.

Material You with dynamic theming. Home screen widgets. Full-text search across all events. Per-event timezone for travel.

No analytics, no tracking, no KashCal account required. Data is stored locally unless you explicitly set up sync.

• Fort Knox Mode: other apps have no access to your events
• Encrypted credentials via Android Keystore (AES-256-GCM)
• HTTPS only: cleartext traffic blocked
• No WebViews: native UI only
• Minimal permissions: only what's necessary
• Fully auditable: open source codebase
