ownCloud is a self-hosted file sync and share server. It provides access to your data through a web interface, sync clients or WebDAV while providing a platform to view, sync and share across devices easily — all under your control. ownCloud’s open architecture is extensible via a simple but powerful API for applications and plugins and it works with any storage.

You and others can comment on files, tag them, and see the comments and tags by others. ownCloud lets you share files, calendars and other data with users on your ownCloud or on other ownCloud servers ("federation"). User names on remote ownCloud servers ("Federated Cloud ID's") are auto-completed once the server is added as trusted (this can be done automatically on the first time you share with the other server) and files you share with others always remain on your server. You can also share via public links with or without upload rights, password protection and automatic expiration.

wherever it is.

You can add external storage to your ownCloud with Dropbox, SWIFT, (S)FTP, Google Drive, Amazon S3, OpenStack Object Storage, local hard drives, WebDAV, SMB/CIFS and more. You can control if you want to retrieve thumbnails and how often you want to check for changes. With the ownCloud Encryption app, data can be encrypted on local and/or remote storage. Keys never leave the ownCloud server but can also be managed by an external key management tool.
