DecSync CC appDecSync CC is System tool that is open source under the GPL-3.0-only license. DecSync CC synchronizes contacts, calendars and tasks using DecSync. It stores this data in a shared directory, using Syncthing, Google Drive, Dropbox or any other file synchronization service.
Syncthing synchronizes files directly between devices, without storing the data centrally or requiring a server. DecSync CC works with any file synchronization service, but using Syncthing is recommended as your data stays on your devices.
The UI is based on the one used in DAVx⁵.
