  • Password-protected vault

Sync has been a well-known platform for its 5 GB free storage, 30-day file history, and end-to-end encryption.

It does not support opening many files, but it’s a great platform to save any file format.

The free plan has basic sharing features. You can password-protect files and enable enhanced privacy protection to ensure your files don’t fall into the wrong hands.

However, it only supports sharing of 3 files for free. Sync also has shared folder options to manage folders with members.

Above all, it’s a fully secured end-to-end program supporting two-factor authentications and PIN security on mobile, making it a great cloud storage platform.


pCloud Interface
