We don’t limit your speed or storage space: our technology works especially well with huge files. No storage limits • Sync as much data as you have on your hard drives. Automatic camera backup • Sync will back up photos and videos as soon as you take them. • You can then delete photos from your phone and save space. Direct transfers, no cloud • Your information is never stored on servers in the cloud, so nobody can access it without your permission. • Transfer files directly and fast using peer-to-peer technology (p2p). Any device and platform • Access folders and upload files to your tablet, PC, Mac, NAS, and even server. Supports all file types • Add photos, videos, music, docs, and PDFs from other apps to any of your synced folders. Save space • Selective Sync lets you save only the files you need.
