EteSync

End-to-end encrypted sync for contacts and calendars

About EteSync

EteSync is a synchronization service that syncs contacts, calendars, tasks, and journals with end-to-end encryption between devices. It runs on your own server or home hardware, so your data stays under your control instead of depending on a third-party cloud service. That makes it a practical fit for homelab users, small teams, and organizations that value privacy, ownership, and predictable costs over time.
