Flock

A secure contact and calendar syncing application for Android.

Flock is a replacement for the default contact and calendar synchronization services provided by Google. Flock provides end-to-end encryption between multiple Android devices, putting the privacy of your contacts and calendars back under your control. To facilitate syncing between multiple devices a "Sync Service" is required, this can be any standards compliant WebDAV server that conforms to the following RFCs:

RFC 2518 - HTTP Extensions for Distributed Authoring -- WEBDAV
RFC 4918 - HTTP Extensions for Web Distributed Authoring and Versioning (WebDAV)
RFC 6352 - CardDAV: vCard Extensions to Web Distributed Authoring and Versioning (WebDAV)
RFC 4791 - Calendaring Extensions to WebDAV (CalDAV)
RFC 1337 - TODO: A few more small specs to include...

Building and contributing code

Instructions on how to build Flock, as well as on how to setup an IDE to modify it can be found in the "BUILDING.md" file.
