Sync for Mac

  -  32.8 MB  -  Freeware
Sync for Mac is a fully encrypted, zero-knowledge cloud service that makes it easy to store, share and access your files from everywhere - your privacy guaranteed. Sync for macOS was founded in 2011 by Thomas Savundra, Suhan Shan and Darius Antia, the same team that started Netfirms - one of the world's largest web hosting companies. They wanted an easy way to store and share their important files online. The trouble was, that meant giving third-party service providers access to their data. Get started with 5 GB storage - always free! Upgrade to Sync Pro for Mac for additional features and space.

Features and Highlights

100% private cloud
The app's unique, zero-knowledge storage platform guarantees your privacy by providing end-to-end encryption, and only you have access to the keys.

Automatic backup and sync
Back up your files all in one place, and keep them synchronized across all of your computers and devices. Restore any version of any file, any time.

Access from anywhere
Easily access your files from anywhere with desktop apps for Windows and Mac, and mobile apps for iPhone, iPad, Android, and the web.

Share files securely
Send files securely to anyone, even if they don't have an account. Stay in control with password protection, notifications, expiry dates, and more.

Collaborate with teams
Invite your team members to work together on documents in the office or remotely, with multi-user administration tools, permissions, and access controls.

Compliance built-in
Ensure your company meets data privacy compliance - important if you operate in a regulated industry, or store sensitive information in the cloud.
