Resilio Sync is a personal file sync and sharing app built on peer-to-peer technology. It automatically keeps folders of photos, videos, music and documents in step across your devices. According to the vendor, you can send large files to several recipients without a permanent sync connection, change or revoke permissions through Advanced Folders, and use Selective Sync to download files only on demand. Bandwidth limits can be set. Resilio Sync is an app you install on your own devices.
The vendor, Resilio, LLC, is based in the United States (Pleasanton, California) and has been part of the US company Nasuni since March 2026. It therefore falls under US jurisdiction, including the CLOUD Act. Because files travel directly between your devices, no copy needs to sit with a cloud provider, and the website describes sending files as 'cloud free'. A European organisation that wants to limit processing by third parties should review the vendor's privacy policy and any metadata services the app relies on.
