First it was floppy disks, CDs, and DVDs. Now even USB drives are slowly dying off. 

With the advent of online storage services, the need for physical data storage devices is dwindling. Today, with the help of cloud storage, we can access our files from practically any location or device. However, the market for file storage providers is already fairly crowded, with established names like Dropbox, Google Drive, and MEGA dominating the field.

But this doesn’t mean that newer providers with a lesser-known pedigree aren’t worth checking out. That’s why we’ve written a review to give you greater insight into one of these upstart competitors. Sync is a slightly lesser-known brand that over the years has become the cloud storage solution of choice for many satisfied customers.

Sync is a security- and privacy-focused cloud storage provider. Like MEGA, its main feature is its state-of-the-art end-to-end encryption, which prevents anyone – Sync included – from accessing your files. On top of that, it features the capability to seamlessly sync designated folders and easy file-sharing packaged in an intuitive, simple-to-use tool. 

Unfortunately, as you’ll see in our review of, it falls short in the same areas as MEGA, with strong security features standing in the way of advanced collaboration capabilities. However, its simplicity and competitive pricing make it one of the most popular cloud storage services around. It’s especially great for privacy-focused users who don’t mind subscribing annually.


Sync’s main purpose is, well, to sync your files across all your devices through its cloud storage. On top of that, Sync serves as a typical cloud storage service, with a focus on security and simplicity. Hence, as our cloud storage review will illustrate, it doesn’t boast fancy integrations and collaboration features like Google Drive. It does, however, cater to customers looking for an easy-to-use, ultra-secure storage platform that performs most of its functions by itself. 

File syncing: First up in our review is this provider’s namesake and core feature. Syncing allows you to constantly update the files and folders you choose across all your devices. Whichever device you install the Sync client on will automatically download or upload files to make sure that all the files and file versions are the same in the predetermined folders. While we were writing our Sync cloud review, the desktop client allowed us to choose which folders to sync during installation, with the default location being in User/Username on Windows. 

Whether you want to manage music, photos, PDF files, or other work documents, file syncing ensures that wherever you might be at the moment, you’ll have access to your files. You can freely make additional subfolders and customize which folders you want to be synced. However, you cannot include external drives or any other folders outside of your main sync folder. 

Anything you want to be synced has to be placed inside the main sync folder or its subfolders. Drawing from our experience while compiling this cloud review, we found this to be somewhat annoying, but definitely not a fatal flaw of the system. While one could assume that this is a security precaution, Sync’s equally secure competitor – MEGA – allows you to freely include additional folders to be synced, or exclude them.

The option to choose which files/folders you wish to exclude from syncing is pretty useful, as you can save space on your devices by not downloading your whole Sync folder to each and every one of them. This is done via the Vault folder. Since that folder doesn’t sync to your devices, we found during our review for that we could only access the Vault via the browser-based dashboard.

File storage: Besides syncing, one of the main purposes of this service is storing your files online. Maybe you’re low on space on your PC, afraid that you might accidentally delete or edit important files, or you just need a safe space to keep sensitive work-related data. If any of these apply to you, storing your files on Sync’s servers is a life-saver. 

Like its competitors, Sync offers paid plans that include huge amounts of storage space and can basically serve as alternative hard drives. Even a quick starter plan review will clearly tell you that the free plan won’t be enough if you intend to use Sync for storage, as it only gives you 5 GB, with the possibility of expanding that by completing certain tasks. More on that in the Pricing section of this article.

Uploading, downloading, and generally managing your cloud storage is incredibly easy and intuitive. When using the desktop app, you’ll basically be working inside of your operating system’s interface, where the sync folder appears and acts like any other ‘regular’ folder. Hence, adding or removing files from the Sync folder is done the same way as you would normally move them. 

The web-based interface is more robust and is neatly designed. On, review and backup your files easily, then move or upload new files by dragging and dropping them into the appropriate fields.

File sharing: One of the things we absolutely love about Sync is how easy it is to share files and folders with other people. There are two main ways to share files. The first is by creating a link to a file or folder. This generates a unique, encrypted link that is sent to the recipient’s email address. The user you’ve sent the link to just clicks on it and can immediately start downloading the file. No annoying ads, no need to sign up for Sync, nothing – just quick and simple sharing. This is exactly why there are so many stellar reviews online – its simplicity of use.

When creating and sharing file links, you have several useful features at your disposal, although most of these are for paid subscribers only. For additional security, you can add a password to your link or set up a limit on how many times the file can be downloaded before the link self-destructs. Furthermore, you can see how many times a file has been downloaded through your link and get email notifications for link activity. As usual, you can also add expiry dates to links, after which they’ll disappear. 

Another great link-sharing feature we encountered in our Sync review is the ability to set up preview-only mode for documents and images, which allows users only to view, but not download them. Additionally, you can create file request links, through which recipients can upload requested data. The files you share with others retain their encryption, with the sharing link containing the decryption key for accessing them.

The other method for sharing files is by creating collaboration folders. Once you create a shared folder, they are also shared by sending invitations through your email. Unlike links, shared folders require other users to create Sync accounts in order to access them. With Sync Pro, you can set specific permissions for the shared folder: read-only, editable, and so on.

When using Sync cloud services, you can easily track what you’ve shared, and with whom. This information can be found under the Sharing tab on Sync’s web interface. Here, you can see what files and folders you’ve shared, the date of sharing, edit permissions, and security options. You can also revoke access if needed.

End-to-end encryption: When compared to other cloud storage solutions, Sync’s differentia specifica is its bulletproof encryption security system. As we’ve confirmed throughout our encryption review, any and all files you save or share via Sync are protected by end-to-end encryption (E2EE). 

Also known as zero-knowledge encryption, E2EE means that your files are encrypted so that no one – except for you and the people you decide to share with – can ever access your files. This encryption system relies on private keys that are used to decrypt data. They are generated locally, which means that neither Sync nor any third party – including ISPs and government agencies – have access to it. Without that key, decrypting your files is impossible.

While examining the provider’s privacy features for this security review, we noticed a difference between it and similar competitors. Unlike MEGA, another cloud storage provider that uses E2EE, Sync doesn’t actually provide you with keys for decrypting data; the decryption process is automatic. Consequently, when sharing files via links, the decryption key for them is always included in the link and cannot be sent separately. This further simplifies and streamlines the process of logging in to your account and sharing files, without the need to memorize/pull up your private key, all the while retaining the highest level of security.

Password reset – Another difference that became apparent in the course of our review of security features was that this company offers password-reset features. This is pretty uncommon for end-to-end encryption solutions, as it means that you would be communicating password changes with the provider’s server, which would break the encryption chain and make the password available to the provider. 

However, Sync offers two ways to reset your password, the first of which avoids this problem. You can do this by changing your password through the desktop app. This changes the password locally, without transmitting your password to Sync’s servers, thus preserving the encryption of your files.

The other method for resetting your password is through email password recovery. When we were writing our review, this option was turned off by default, as it lowers your overall security level. When turned on, you can get a password reset link via email. Unfortunately, this means Sync will then know your password. The company does state, for what it’s worth, that only its automated system will have access to your encryption keys in this case.

Additional security: Besides the aforementioned security features, Sync has additional safety measures in place to further reduce the risk of any malicious party compromising your account and accessing your data. All interactions between you and Sync are protected by AES 256-bit encryption, preventing anyone from ‘tapping in’ to your connection. Additionally, in our privacy review, we saw that you can add two-factor authentication to your account. With this option enabled, every login attempt has to be verified via email or a verification app.

User Interface and Platform Availability

Sync’s user interface is everything you’d expect from a robust cloud storage provider. Its web-based platform is superbly designed and minimalistic. The main section of the screen is reserved for browsing and managing your cloud storage. On the top bar, you can switch between tabs – Storage, Vault, and Sharing – as well as looking over the history of your actions and adding other users to collaborate.

As other Sync secure cloud storage reviews point out, Sync’s browser interface is extremely pleasant to use. The light-blue-and-white color scheme makes it very eye-pleasing and unintrusive, while the minimalistic design makes finding needed tools and navigation buttons quick and easy. The interface is also very responsive, meaning you won’t lose precious time waiting for the page to load.

Besides the browser-based dashboard, Sync also comes in the form of a desktop and mobile app. The desktop app acts like most sync apps do – mostly running in the background, automatically keeping your folder up to date with your cloud storage. Other than that, you’ll rarely use the app for desktop. It does allow some basic functionalities such as checking upload/download progress, looking over recent transfers, and setting download/upload limits, but you’ll be mostly relying on the web panel.

Of course, there’s a Sync mobile app available for iOS and Android. It has most of the capabilities found on the web panel. You can sort and manage your files, share them, and access your Vault. On top of that, the mobile app also allows you to automatically upload photos and videos, backing them up and potentially saving you storage space. However, we have to agree with other Sync reviews that the app is fairly user-friendly, but lacks some features, especially when it comes to moving files easily.

Ease of Use

The whole purpose of Sync’s clean and minimal design, as well as its straightforward features, is to make the platform extremely easy to use. Whether it’s your first time using cloud storage or you’ve already changed multiple storage providers, mastering Sync will take you just a couple of minutes.

The signup process is simple – you type in your email and choose a password, after which you can start using Sync immediately. If you wish to share files, however, you’ll need to verify your email address first. While we were using Sync cloud storage, we noticed that there was no tutorial on how to use the service, but truth be told, you don’t need one. Everything is very self-explanatory and evident, with all options never more than a click away.

The desktop app installation process is equally straightforward. During installation, you can choose where your sync folder will be placed, and you can also make an account if you don’t already have one. After installation, it will automatically start syncing in the background. This greatly reduces setup times if you’re installing the app on multiple devices. All in all, when it comes to ease of use, you won’t find a provider more accessible than Sync.


Now onto pricing. Sync offers different pricing plans for both individuals and businesses, with pricier plans bringing increased storage capacity. Sync also has a free version with very limited storage and some advanced features missing. This is best used for testing out the platform before making a purchase. Overall, Sync’s plans are very affordable, the only downside being that you have to subscribe on an annual basis.

The Sync free plan nets you 5 GB of cloud storage. While this isn’t much, and is certainly less than MEGA offers, it’s enough if you’re storing smaller documents and not whole libraries. Furthermore, the free plan contains most core features found in the paid plans, allowing you to use it without hindrance. And the best part? You can increase your Sync online storage by installing the mobile app or inviting other users.

There are three individual pricing plans available: Basic, Standard, and Plus. Each paid plan brings unlimited shares, unlimited collaboration in shared folders, advanced sharing options such as expiration dates and download limits, and priority email support. Furthermore, they include HIPAA, GDPR, and PIPEDA compliance. Billing is performed annually and the individual paid plans are as follows:





2 TB



3 TB



4 TB


*currently discounted from $12/month

Next up in our review are the Business plans. They include advanced collaboration features such as increased control over user access and easier sharing among users. As is the case with individual paid plans, there are no transfer limits here, either. Additionally, you can view activity logs to see who has changed or shared files and when they did so. The available plans are Standard, Plus, and Advanced. Business plans are also billed annually.

When compared to its best sync software competitors, Sync’s turns out to be very cheap, especially on a dollar-to-terabyte comparison. However, the downside is that you have to subscribe for a whole year, while almost all other cloud services offer monthly subscriptions. 

If you’re unsure whether Sync is right for you, we definitely recommend testing out the free plan first. While it doesn’t provide a huge amount of storage, it has all the features you might look for in a cloud storage provider and serves as a great test run.

Customer Support

While users rarely encounter issues with cloud storage, you still want to have access to quick and helpful support staff if you do run into problems. Unfortunately, Sync’s support staff can only be reached via email or online form. 

When we contacted them for this review, the staff at Sync compared extremely well to most of their competitors, responding in one or two hours and providing clear information and straightforward solutions. In case you opt for one of Sync’s paid plans, you get access to priority email support, which means you’ll get a response even sooner. Still, it’s unfortunate that there’s no live chat support available.

Besides support agents, you can always consult the detailed Help Center found on Sync’s website. It contains instructions on how to use most features and offers solutions to most of the common problems people face.

Similar products/software


Sync isn’t the fanciest-looking cloud storage provider out there. It doesn’t offer many collaboration features, it doesn’t integrate with other platforms, and it’s not the quickest around. When comparing Sync vs Dropbox, the latter is probably the better choice for the average Joe. 

However, if you’re looking for secure storage, there’s no simpler and easier-to-use provider than Sync. It takes minutes to register and set up, and it immediately allows you to sync all the files you want. Sharing is also easy and lightning-quick, with other options being just a click away thanks to a nicely designed web panel. 

Sync’s free plan is great because it has all the core features you might need, but the small amount of storage it provides means you won’t be able to rely on it forever without switching to a paid plan. All in all, Sync cloud services should probably be the first provider you check out if you’re looking for secure, encrypted cloud storage.

Is Sync com really secure?

Based on numerous reviews, both by users and professionals, it’s safe to state that Sync is totally secure. Thanks to end-to-end encryption, any files you store with Sync are safe from prying eyes.

How does sync com work?

Sync’s main feature is to keep your files synced through cloud storage across all of your devices. No matter where you might be or whether you’re accessing it through mobile or desktop, Sync will automatically keep all your files up to date.

What is Sync good for?
