What is Jumble?

Next Generation Security! Jumble is an always-on email security and data privacy solution. It integrates seamlessly on top of Gmail so you don't need to change a thing, just sign-up and install the plugin for Google Chrome to get next generation email security in a snap!

Get that warm and fuzzy feeling of complete security when you need to send bank details, credit card numbers, health details and whatever else you want to keep private as only the person you send the email to will be able to read it.

Why should I use Jumble?

Most people/businesses only protect their emails while they are in transit (i.e. being sent from your internet browser to the recipient’s browser). However emails live forever and all the data should be protected at all times. The only way to do this is to use end-to-end encryption but it’s usually too technical or time-consuming for people to use. Jumble makes it simple and fast – it takes the pain out of encryption.

What does Jumble do?

In short, Jumble is a tool that allows for seamless and secure email encryption with almost no effort. Jumble is different from existing email encryption schemes insofar as you don't have to be already signed-up with Jumble to start receiving encrypting emails, you will need to register to decrypt these, and send encrypted emails.

Additionally, Jumble works with your existing email address so no need to create a new email account.

Do I need to pay for this service?

Jumble is free for all personal users. It is important that security can be available without paying anything to anyone. As a personal user, Jumble will remain free.

Paid versions are for companies and individuals looking for extra security. Paid versions allow companies to use Jumble encryption with the companies' email domains and also access the software extensions to use Jumble with Outlook and numerous other email clients. Additionally, paid versions offer an extra layer of security, using 2-factor authentication, when verifying the identity of a user.

What's encryption?

Encryption is a way to enhance the security of a message by Jumbling the contents so that it can be read only by someone who has the right encryption key to un-Jumble it.

Is it really safe?

Jumble uses a standard encryption method called AES-256. This method is reputed to be unbreakable within reasonable time-frames and is the current global data encryption standard. Thanks to a 256-bit encryption, decoding a simple line of text will take tremendous amount of time; enough to discourage any criminal or marketing companies from reading your emails.

How does it work?

Jumble is an email encryption service that uses a combination of public-key and symmetric-key cryptography; here's a typical scenario to help explain how the process works:

Alice wants to send Bob a private email, our browser plugin will request a public key for Bob from our servers, if it doesn't exist then we generate a key-pair for Bob; we then lock the private key and give Alice the public key. This allows Alice to send Bob secure email without Bob having to pre-register. Only Bob will be able to access his private key once he has verified his identity.
You can read more about these cryptography types by searching online or have a look at the Wikipedia entries:

Is the paid version safer than the free one?

All Jumble versions offer the same level of data encryption; however, with the paid version there is added protection for your Jumble account through the addition of 2-factor authentication. This provides an additional layer of security every time you use Jumble on a new device, which helps protect you if your password is stolen.

Which email providers does Jumble support?

At the moment we support MS Outlook for Windows desktop, Google Apps for Business, Gmail, & iOS and we're working hard to bring more platform coverage to our users and we plan to launch Jumble support for Android and Office365 imminently with Yahoo Mail, Hotmail and Outlook.com as soon as possible; keep an eye on our Supported Platforms page for more info.

Does Jumble track me or use cookies?

Jumble requires the use of cookies in order to bring you a quality service. Jumble uses Google Analytics which tracks anonymous website usage only, this allows us to understand the capacity of our system and scale it appropriately to provide the best service.

Where is Jumble located?

Jumble is an Irish registered company and uses (as much as possible) Irish and European infrastructure. Jumble data centres are located in Germany.

How does Jumble handle requests from governments or other bodies?

As an Irish company Jumble is obligated to deal with requests from the Irish government and legal system; Jumble does not deal with requests issued outside of Irish jurisdiction.

Importantly, while Jumble stores users' private keys they are only stored in an encrypted format, accessible only by the users' password which is not known or stored by Jumble.

An email has expired - what does this mean?

When sending an encrypted email you can now set an expiration time-limit on the email - once the time-limit has passed it will not be possible for any recipient to open the email.

If you open a Jumble encrypted email and receive an error message notifying you that the email has expired, this means the sender of the email set a time-limit which has now passed.

If you need access to the email, you will need to contact the sender and ask them to resend the email.

An email has been revoked - what does this mean?

Jumble allows users to revoke secure emails they have already sent, this allows senders to block access to emails which may have been sent in error or where, for whatever reason, the recipient should no longer have access to the email.

If you open a Jumble encrypted email and receive a message notifying you that the email has been revoked, this means that the sender of the email has revoked access to the email.

If you need access to the email, you will need to contact thr sender and ask them to resent the email.

How can I reset my password?

We don't store your password in a readable format so we can't tell you what your password is. Your password is the key to accessing your private key, if you lose your password you also lose access to your private key which means you won't be able to read any emails sent using the corresponding key pair; we suggest you take note of your password somewhere safe.

Having said that you can request an account reset by emailing us at reset@jumble.io. If we reset your account your can choose a new password but you won't be able to read emails already sent using Jumble.

Where is the Jumble privacy policy?
