Install ownCloud or NextCloud on your personal server or let us build a dedicated ownCloud or NextCloud server for you, hosted by lnxsites, at a domain name of your choice.  Inquire by email: site_admin(at)lnxsites.com. Configure as many user accounts as you require. Upload your files, photos, videos, calendars, and contact address books, and synchronize them automatically among your server, desktops, laptops, tablets, android and iPhone devices. Collaborate and edit documents with other registered users or guests with whom you have granted share access to selected documents or cloud folders. NextCloud is also integrated with OnlyOffice Server.  Everything is SSL encrypted for security.
