EteSync: End-to-End Encrypted Calendar & Contacts Manager
Private, secure, and feature-rich calendar and contacts manager with client-side encryption for seamless device syncing
What is EteSync?
EteSync is an open source, end-to-end encrypted, and privacy-focused contacts and calendar synchronization service. It allows users to keep their personal information and calendar events private while still being able to seamlessly sync their data across multiple devices.
Unlike most other sync solutions, EteSync uses client-side encryption rather than server-side. This means all encryption and decryption happens only on your devices, and EteSync's servers store fully end-to-end encrypted data that they cannot decrypt themselves. Only you have the decryption keys. This prevents third parties from accessing your sensitive calendar and contacts data without your consent.
EteSync aims to combine privacy, security, and usability. Setting up takes just minutes and works across iOS, Android, Linux, Windows, macOS, and the web. EteSync also handles conflict resolution and syncing deletions across devices.
While free accounts support core functionality, paid accounts provide additional storage and advanced features like shared calendars. The service is developed by a non-profit organization as an alternative to surveillance-based tech giants. For those wanting convenience without compromising privacy, EteSync presents an appealing self-hosted sync option.
