Upcoming Cubby Maintenance

We are constantly striving to provide you with the best cloud service possible. In order to do this, we sometimes must take Cubby offline to ensure that all of the necessary improvements are properly implemented.

During this maintenance cubby.com and all cloud-based services will be unavailable. This includes access to cubbies on the cloud, cloud-based syncing, and access from a mobile device. Local content and DirectSyncTM will remain available.

The scheduled maintenance will affect users for approximately 8 hours on Sunday, September 8, 2013 at the following local times:

  • 6:01 AM UTC – 2:01 PM UTC
  • 2:01 AM EST – 10:01 AM EST
  • 8:01 AM CET – 4:01 PM CET

We appreciate your understanding and apologize for any inconvenience this may cause.

Thank you,

The Cubby Team

Now in preview: Easier account switching, public link improvements and more

We’re happy to announce a few small but powerful features that are now part of Cubby Preview. With your feedback we hope to release these features to all Cubby users soon.

Improvements to account switching

When reinstalling Cubby or switching between accounts, Cubby now provides the option to rejoin previously synced cubbies.


Improved public link creation (Windows & Mac)

Mac users can now create public links directly from their Finder context menu.

After generating public links, both Windows & Mac users now will be provided with a single window showing you the link to the individual file, rather than all public links within that cubby.


Automatic ”switch back to live” on Mac host

Mac users can now easily switch between the Preview and Live versions of the Cubby Mac hosts from their About page in Settings.


Sync-related improvements

We have also made various improvements to our sync engine.

Introducing: Cubby enterprise (preview) and Cubby pro team trials

LogMeIn has long developed solutions for IT and business, and Cubby is no exception. In the latest update to Cubby, we’ve unveiled two key elements that will make it easier for your business to try, adopt and manage Cubby for your workplace.

Cubby enterprise

We built Cubby to be a secure, enterprise-grade solution for using the cloud in business so you can manage data security, compliance and risk when it comes to intellectual property. With the new Cubby enterprise, currently in preview, you can now:

  • Introduce or adopt Cubby in the workplace to boost productivity and collaboration across the board.
  • Hold the reigns on how your company’s data is shared, who is sharing it and who it’s shared with.
    • Disable public sharing
    • Prevent resharing of folders
    • Limit public sharing to team-members only
  • Easily onboard and off-board users from Cubby

Cubby enterprise is currently available in preview. For more information please visit: https://www.cubby.com/enterprise/


Cubby pro tream trial

We know giving Cubby a test-drive is essential for making sure it’s the perfect fit for the way you do business. With the new Cubby pro trial, companies can now try pro features free with their entire team for 14-days, including:

  • Unlimited DirectSync™ without the cloud
  • Cubby Locks
  • 100 GB shared storage per user
  • Ability to invite an unlimited number of colleagues to join the trial
  • Basic user management

Starting a Cubby pro trial is simple: new users can click Try it free from the Cubby pricing page, or if you already have an account, simply click on the Team page once logged-in.

Now in Preview: Support for network-attached storage (NAS) and external hard drives, plus drag-and-drop and multi-file uploading

A few weeks ago we told you about the the new Cubby Preview Program —  a place for our early-adopters and loyal users to be the first to get the latest features and fixes before they’re officially released.

Today, we’ve loaded-up our preview version with some of the most frequently-requested features and we’re looking to get your feedback. Check out what’s being previewed (below), then go here to learn how to get started.

Support for network-attached storage (NAS) and external drives

Preview users can now create a cubby from a fixed or removable disk such as an external hard disk drive, USB stick (pen drive), Flash reader or similar. Users can also now create a cubby from content associated with network-attached storage (NAS), also known as file-servers.

Drag-and-drop upload at cubby.com

Preview users can now drag and drop multiple items from anywhere on their computer into their cubbies via cubby.com. The upload status for these items will appear at the bottom of the page, allowing users to watch the upload process in real-time.


Multiple file/folder upload via cubby.com

In addition to drag-and-drop, preview users can now upload multiple files at the same time through cubby.com by simply selecting “Upload” and then their files. Chrome users will also be able to upload multiple folders.


Detach account on a Windows PC

To make it easier to stop using one LogMeIn ID and switch to another, we’ve added a detach feature for Windows users. To access, open the Cubby application and go to Preferences– the next time you launch Cubby, you’ll be asked to associate it with another account.


Sync improvements
As we do with every release, we’ve identified a few areas to improve our sync engine speed and performance.

Once you’ve decided to make the switch to Cubby Preview, make sure you drop us a note and let us know how it’s going.

Introducing: Offline file viewing for mobile devices

Update 5/16/13: This post has been updated to include the latest update to Cubby for Android

If you’re one of the millions of business travelers jet-setting 50,000 miles up in the air, you know the pain that a few hours without an Internet connection can have. In the sky or not, you want access to your team’s files. In the latest Cubby for iOS and Cubby for Android updates, we’re helping you accomplish just that– being productive in more places–  with the introduction of offline file viewing.

Offline file viewing:

Notice in the screenshot below that the user, despite being in “Airplane Mode” (an iOS setting which cuts off WiFi and 3G/4G connection), is still able to view and access his Excel Spreadsheet for an upcoming work event.


This is made possible by a solution now in Cubby called caching. Every time you access a file online, Cubby saves that version of the file so that you can view it offline. Cubby caches files automatically in the background as you access them, so there’s nothing more you have to do. The files you need, when you need them– that’s what inspired this feature.

Browsing and searching in offline mode:

We also gave Cubby the ability to remember all of your file names and the names of cubbies and folders. That means you can now browse cubbies and folders or search for those “need-it-now” docs when your device is without a connection. 

Save for offline mode:

Don’t forget, these great features are in addition to the “Save for offline mode” feature that Cubby was born with. As a reminder: simply select any file, go to its info page, and choose to save it for offline. The document will always be available to you and will always point to the latest version from your last WiFi connection.

–Additional features–

Enhanced image viewing for iOS:

We know some of you wanted an easier way to view multiple images in the same Cubby or folder. The latest Cubby for iOS update also you to simply SWIPE to view the next photo in your list. It’s that easy.


(We’ll be working on this for Android, too. Stay tuned).


Android tablet support (coming soon):

A new update to Cubby for Android is coming soon for the large-screen experience on your favorite Android tablet. With tablet support, Cubby will soon provide “two-pane mode”, allowing you to browse your cubbies (on the left) and view its contents (on the right) from one screen. Stay tuned over the next few days for this update to appear in Google Play.


Now, it’s your turn. Help us create the next, best set of Cubby features: tell us how you’re using Cubby and with whom. Simply comment on this post and we’ll be sure to take note!

Introducing: social integration, bandwidth improvements and more

With the latest update to Cubby you may find yourself earning more gigs, uploading files quicker, and altogether being better informed about the status of your syncing. Plus, we launched a few other neat items, too (Cubby Preview program, anyone?). Check out the details below.

Referral link social integration
Share your personal referral link directly to Facebook, Twitter, and LinkedIn. The more friends and colleagues you refer to Cubby, the more gigs you earn. Remember: they need to install the app.



Bandwidth usage improvements
We’ve introduced the first in a series of improvements to control bandwidth usage. With this release, upload bandwidth is now automatically adjusted by your computer’s operating system to optimize upload speed. Download bandwidth is not impacted. In a future release we plan on introducing manual control over bandwidth usage and limits. These improvements are in response to your comments and votes for the item Bandwidth Usage Control.

Improved sync status messaging
For an active download/upload, Cubby displays the percentage remaining rather than the file count and size.
For a new cubby, the progress spinner appears immediately and Cubby informs you that it is “determining what to sync” as the first stage in the sync process.

Coming soon: Cubby preview program
Join the Cubby preview program to get the latest features and fixes before they are officially released. Right now, we don’t have any features available for you to try. But, when we do, we’ll be sure to let you know.

Performance Improvements
As we do with every release, we’ve introduced a number of performance improvements.

Ready to dig in? Cubby updates automatically, so look for version– you’re probably ready to go.

Your custom referral link (and more) is here

Your ideas lead to new features. That’s how Cubby works around here. We have a hard-working team monitoring, listening and talking to customers around the clock– not to mention, a talented (and fun) group of developers ready to create, design and code.

Here’s the latest update which was released magically (thank you, automatic updates) to you, your friends and colleagues on March 7, 2013:

Custom referral link

As requested, we’re making it easier for you to share Cubby Love. We’ve introduced a link that you can copy, paste and post to your favorite social spot. You’ll find your link in the More Space? section of cubby.com once you’re logged-in. Invite away.


Orange cubbies = Improved tracking of syncing issues

As requested by Cubby user Scott Bilas, we’ve made it easier for you to identify sync issues. We call it the “Orange cubby” fix.

When you see an orange cubby on the desktop application, click Issues to see detailed information about what might be preventing your sync from finishing. No more guessing. We promise.


Time stamp improvements

As requested, we’ve made improvements to how Cubby handles file time stamps. Cubby will preserve the modified date, but the creation date will be when the file first gets synced to a “new” computer.

Referral tracking improvements

We made some improvements that help ensure you’ll get +1 GB referral bonus when a friend installs Cubby on his PC or Mac.

Improved syncing

Lots of little fixes to make Cubby faster and even more reliable.

Note that Cubby should update automatically to the latest version, which is

Technical deep dive: Cubby security and Cubby Locks

After our last blog post many of you asked for more details about the Cubby Locks feature. It’s challenging to explain Cubby Locks in a way that’s technically accurate yet still easy to consume. However, since Cubby Locks is a unique and powerful feature that helps set Cubby apart from similar services, we encourage you to take the time to understand what Cubby Locks is and what it isn’t.

The first key idea is to understand that data on the cloud in a locked cubby is encrypted and can only be decrypted by your Cubby password. With most similar services, a password is used to simply keep you in or out. That is, a password is used to determine if you have the right to access the service and your data. With most other services, your data on the cloud is not encrypted or encrypted with a key which is stored somewhere along the data. This means it can be exposed to a rogue employee of the storage service provider, or anyone who manages to bypass the password-protection layer or gain access due to an error in the application.

Cubby Locks

Cubby Locks utilizes some heavy-duty math to keep your data protected. Even a rogue employee or someone who manages to bypass password-protection would find your data useless without your exact password. And just to clarify a very important point: “Data” throughout this post refers to files at rest in the cloud.  Cubby Locks does not provide data encryption on your devices; it’s up to you to secure those. And to get another item out of the way: Data in flight (that is, being transferred between your devices and the cloud) is always transmitted over SSL/TLS with all cubbies, regardless of Cubby Locks.

First let’s look at how a standard cubby works – one that does not take advantage of Cubby Locks. In our data centers all files in all cubbies are stored in encrypted form using the AES-256 symmetric encryption algorithm. The key used for this is the Cubby Data Key (CDK) and is randomly generated for each new cubby. CDKs are stored in our database alongside with other properties of the cubby. When you log in to cubby.com, the web application fetches the CDK from the database and uses it for encrypting and decrypting your data when you upload or download files from your cubby. Like with most other services, your password gets you in to the web site but is not adding any extra encryption.

During your first login to Cubby a series of events happen. First we generate a symmetric key called the User Symmetric Key (USK). We encrypt the USK with your password and store it in an encrypted form (AES-256) in our database. Second, we generate a 4096-bit RSA key pair called the User RSA Key (URK). We encrypt the private part of the URK with the USK and store it. The public part of the URK is, as its name implies, stored in plain text. Both USK and URK are specific to and generated for the user account. If you are not familiar with asymmetric encryption, here’s the shortest possible introduction to asymmetric crypto: Anything encrypted with the public key can only be decrypted with the private key and vice versa.

Still with us? Now, let’s take a closer look at Cubby Locks. When you lock a cubby we encrypt the CDK with the public part of the URK, store it in this form and delete the plaintext CDK from the database. Remember that this CDK can only be decrypted with the private part of the URK. That’s all. Simple, right? Here is the chain of encryption at this point:

  • Your password –> USK –> URK –> CDK –> access Cubby data.

The items on the left side of any arrow are the key for the encryption, while the items on the right side of any arrow is data to be encrypted. So the arrow means “right side is encrypted with left side.”

What does this all mean? Every item in this chain is stored only in encrypted format in our database except for the password, which is not stored at all by us. In order to do anything with data one needs to unlock this chain, and that can’t be done without your password. That’s why we prompt you for your password so often, and this is why no one, not even a LogMeIn employee or a hacker, can read your data without knowledge of your password.

Finally, let’s discuss the so-called Recovery Key (RK). In practical terms, you use the Recovery Key when you forget your password and must reset it to something new. As discussed above, there is no way to access cloud data in a locked cubby without your password. Without the Recovery Key, the situation would be this: “Forget your password – lose your data on the cloud.”  That is, if you were to forget your password and reset it through the standard “email me a password reset link” mechanism, your locked cubbies would be deleted from the cloud and you would be forced to re-synchronize all your data. To users a chance of avoiding this, we generated a Recovery Key for your account when you access a locked cubby for the very first time; the Recovery Key is a cryptographically random 32-character alphanumeric string. We then encrypt the USK with this Recovery Key using AES-256. (Remember,  cubby.com at this point has your plaintext USK since you have just provided your password). So now we have two copies of the USK in the database, one encrypted with your password and the other encrypted with the Recovery Key. When you go through the forget password process and enter your Recovery Key, we use it to decrypt the USK, which is then re-encrypted with your newly created password. This way you can keep your data synchronized with the cloud even if it was in a locked cubby. There is only one Recovery Key per user, so we strongly encourage you to print it and keep it safe. The Recovery Key is stored in the database encrypted with the URK, so it’s only available for you to view online after you enter your password.

  • Recovery Key –> USK –> URK –> CDK –> access Cubby data. 
  • Your password –> USK –> URK –> Encrypted Recovery Key –> Recovery Key.

We should also clarify that there is a case when a Recovery Key will be generated for you even if you don’t lock a cubby yourself.  Namely, a Recovery Key will be generated for you when you are invited to a locked cubby or are the member of a cubby that gets locked by its owner.

In many cases there is a balance between security and ease of use. The more secure you want to keep your data the more complex the process gets. With Cubby Locks you get a solution that’s among the strongest security measures on the market, yet still provides a smooth user experience and ease-of-access to your data.

Thanks for sticking through this. We hope we managed to meet the challenge of making Cubby Locks clear.  We’ll be glad to clarify if you have any questions.  Don’t hesitate let us know what you think or what you find unclear.

Officially Out of the Box: Cubby now generally available for your biz

Well, you did it. The Cubby beta attracted more users than any other in our company’s history. Over the past week we proudly peeled-back the “beta” label off our logo. Cubby is now official.

Over the past several months, we have read every comment and considered your input greatly. You told us where the bugs were (we squashed ‘em), you told us what you love (thanks!) and you told us how we can be better (we needed that). Many of you have been with us since April. And already, we’re hearing from consumers, professionals, teams and even entire businesses all over the world that they are adopting Cubby.

The great thing about Cubby is that it’s new and there’s still time to shape its future. So, whether you have a question or idea, we welcome you to visit us at help.cubby.com. The conversation, the innovation and the excitement continues.

Enjoy the now generally available, business version of Cubby.

Cubby – it’s (almost) go time!

Cubby is almost ready to meet the rest of the world. And we have beta users like you to thank for it.

When we officially launch, there will be two versions of Cubby to choose from. The basic version, offering 5GB free and the anytime, anywhere access that keeps you in control of your stuff, and a new pro version designed so you never have to worry about file sizes or security again.

Pro version
•100GB cloud storage
•DirectSync™ unlimited syncing without the cloud
•Cubby Locks advanced security

In appreciation for your continued contributions to making Cubby great – and in response to the deluge of emails we get daily asking, “how can I buy more storage?!” — we’re happy to announce that beta users can now get an additional 100GB of cloud storage and lock in their first year of Cubby Pro for only $3.99/month (billed annually). That’s more than 40% off the GA price while we’re still in beta.

Already using Cubby Locks and DirectSync?  We encourage you to keep using these features throughout the beta. Like the hundreds of beta products before us, the purpose of Cubby beta has been to get your feedback as we strengthen our features and iron out the wrinkles. We believe DirectSync and Cubby Locks, in their full-form, will be essential to our business users with Cubby Pro accounts. This leaves business users with the flexibility to take advantage of our cloud or no-cloud options, while at the same time, giving our Basic users up to 25GB free along with the cloud features they’ve come to know and love. When the beta testing period is over, we’ll be sure to let you know well in advance.
