Now let’s dive deeper into this review:

Ease of use 

Getting started with doesn’t take longer than 10 minutes.

Creating an account gives you 5GB of file storage that doesn’t expire. The system prompts you to get the desktop app and guides you through the installation process. You can also drag and drop files into the web client.

The whole setup, file upload, and synchronization process is fast and effortless.

Features emphasizes security but also features handy features for personal and business use alike:

Advanced File Versioning

One of Sync’s most useful functions is file versioning. Free users can reverse file changes for 30 days, while premium accounts enjoy 365-day file versioning and backup. With account rewind, you can protect yourself from ransomware by shifting your data to an earlier version.

And, only the most recent file version counts against your storage allowance. You can backup as many files as you want without worrying about running out of space.

Safe Sharing 

Share file and folder access, without compromising security. includes share controls like read-only (or preview-only) access, password protected sharing, expiry dates, and download limits.

If you lose one of your devices, you can revoke access to your data with a remote device lockout. You can also withdraw shared access at any time.

Privacy Protection Compliance

If your business deals with sensitive data, you’ll be happy to learn is the perfect cloud solution. The platform is compliant with:

  • HIPAA and similar regulations related to personal healthcare information (PHI)
  • GDPR, which applies to European and UK user data alike
  • PIPEDA, Canada’s federal law on personal data privacy for the private sector.


Unlike other cloud storage providers (like Google Drive or OneDrive,) the API hasn’t been published. The API allows third-party apps to integrate easily with the platform.

So, why doesn’t Sync publish it? Because they’re committed to preventing third-party access. Without a published API, no external companies can see or interact with your data. This extra layer of security ensures your information stays safe and private.

That said, Sync still offers some useful integrations. You can upload files directly from your Drive account from both mobile and desktop. Sync also has full support for all Microsoft Office formats, and virtually all photo formats. You can use it to store Adobe PDF and PSD files, too. Security 

When it comes to data safety and privacy, is one of the best cloud storage options. Built around zero-knowledge encryption, the platform secures your information and doesn’t store your keys. This means can’t access your files, even if it were served a government order. encryption uses 2048-bit RSA keys, and TLS/SSL encrypted channel transfer for all communications. The Sync cloud storage itself uses AES-256 encryption to protect data from potential attackers.

But, since doesn’t have your key, forgetting your password means losing access to all encrypted files. To prevent that, you can disable end-to-end encryption and opt for other security features (like two-factor authentication). Login and Setup 

Installing is quick and effortless. The website recognizes your platform and recommends the installer for you. I tested the Windows 10 download, and I was happy with both the speed and ease of installation/setup. Even a beginner can get started with in under ten minutes.


With the mobile app, you can access your synced filesbackup photos and videossend large files, and collaborate on shared folders.

The Android app installed and ran smoothly on my device. I was happy to discover I could upload files directly from Drive and synchronize the photos and videos on my phone.

To view and edit files, though, I had to download them. This is expected if your data is secured with end-to-end encryption, but it could slow you down.

The iOS app shares the same functionality and is generally well-liked by reviewers. Upload & Download Speed 

Sync doesn’t restrict your speed, regardless of what plan you’re using. But, will never be a speed champion. When you use end-to-end encryption, it takes some time for files to be secured. The maximum transfer speed with is 40 Megabits per second.

You’re not likely to notice the difference in smaller files. Uploading a 500MB file only took a couple of minutes, and it was automatically accessible across devices. When I tested it with larger files, performed admirably, though it’s not the fastest cloud storage I’ve used. Pricing Plans

All plans come with free end-to-end encryption and support across devices. Pro accounts not only expand your space, but they also give you additional functionality. Here’s how account perks differ: Free Account

The free starter account gives you 5GB of Sync cloud storage. Since it’s not a free trial, the platform doesn’t ask for a credit card or give you a time limit. You can earn up to 25GB of space by referring others. Free accounts enjoy essential features like file versioning, vault storage, secure sharing, and collaboration tools. This makes one of the best free file sync software platforms in 2020.

  • Basic ($8 per month; $96 per year), with 2TB of storage
  • Standard ($12 per month; $120 per year), with 3TB of storage
  • Plus ($15 per month; $180 per year), with 4TB of storage

Sync Pro Teams

  • Standard ($5 per user, per month), with 1TB of space for every user.

If you have any questions or technical issues, you can get in touch with the Sync team through a contact form. While I was researching for this review, I reached out to them twice. Both times I contacted customer support from a free account, and they were responsive and quick at answering the question.

Pro accounts have priority email support.

You can also consult the help center for detailed support articles, answering common questions. The platform promises 99.9% SLA uptime, meaning you’re unlikely to see down. But, you can consult the status of all systems in real-time on the Sync website. User Reviews

Try it out today with a forever free account or invest in more storage with the premium plans! Competitors

File sync software reviews mention among the best options on the market. But how does it stack up to other platforms?

pCloud vs. Sync

pCloud offers secure cloud storage services, making it a popular alternative. The platform gives you more free storage, but you have to remain active (at least every three months) to prevent account termination. pCloud does offer end-to-end encryption, and they’re very transparent about their business. But, the advanced security will cost you – pCloud Crypto comes at an additional monthly fee.

Google Drive vs.

Google Drive is a champion at integrations. The platform’s advanced functionality (as a part of the G-Suite environment) and pricing are hard to beat. But, Google Drive doesn’t have zero-knowledge encryption, nor do they protect your information from third-party access.

OneDrive vs.

Much like Google Drive, OneDrive is built for integrations, not privacy. Since it lacks end-to-end encryption, OneDrive is far from the best option for sensitive information. vs. Dropbox

Both frequently featured on home cloud storage reviews, Sync and Dropbox have several key differences:

  • Dropbox gives you less free storage, with free accounts only providing 2GB of space.
  • uses end-to-end encryption, while Dropbox doesn’t.
  • The zero-knowledge encryption on means file uploads will be slower, though you’re only likely to notice it for large files.

Overall, is the better choice for privacy, though big players like Google Drive, OneDrive, and Dropbox might offer more in terms of integrations.

It’s an affordable, secure, and easy-to-use platform for business and personal use alike. Get started today with 5GB of free Sync cloud storage and see if it’s right for you!
