Sync is the best way to transfer files between your Mac, PC, NAS, and even server. Create your own private cloud. Connect devices and sync files securely without sending them on third-party servers. 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. To get the best performance and to avoid running up your data charges while syncing folders, we recommend leaving the "Use Cellular Data" setting off.

Your files. Your server. Your ownCloud. Connect to your ownCloud Infinite Scale (oCIS) or ownCloud Classic server and access your private cloud from anywhere. Open source, self-hosted, no third-party cloud required. ownCloud gives you full control over your data. Whether you're a teacher accessing the school cloud, a sysadmin managing a federated deployment, or someone who simply refuses to hand their files to a big-tech provider — this app is built for you. FEATURES - Browse, Edit and Create files Work with your files directly on your device with Files integration, built-in markup tools*, and the document scanner*. Switch between list view and three grid views — all updating live as changes happen locally or remotely. - Built-in viewers View common file types right in the app. Swipe through images in carousel view. Navigate PDFs using their table of contents or full-text search. - Spaces (oCIS) On ownCloud Infinite Scale servers, organise work into Spaces with dedicated permissions, members, and quotas. Full Spaces support is built in. - Sharing and Collaboration Share files and folders with other users on the same server or externally via public links. Fine-grained permissions, password protection, and expiry dates give you control over every share. - Search (Local and Remote) Filter by date, size, type, or location. Save searches and create reusable templates. Local search works fully offline. On oCIS servers, server-side search can also find content inside files (depending on server configuration). - Offline Support Mark files and folders for offline availability. Work without a connection. Changes sync automatically when you're back online. Built from the ground up with offline-first in mind. - Multiple Accounts Connect to several ownCloud servers and accounts simultaneously. Switch between them seamlessly. - Deep OS Integration Native iPadOS multitasking, drag and drop, File Provider, and Shortcuts support. Built by developers who care about how apps should feel on Apple platforms. - Security The app tracks your server's TLS certificates and warns you about unexpected changes. Review certificate details (including a diff of what changed) and accept or reject — right from the app. * Some features may require an In-App Purchase or Subscription.
