Emails & Co as always.
Now Robust.
Finally Private.

The most secure way to enforce your privacy online. End-to-end military-grade encryption in a click, compatible with anyone.

End-to-end encryption
All your data are encrypted & decrypted in your browser only, automatically. Legal orders, spying, hacking: it doesn't matter, it will still be encrypted because the only way to decrypt your data is based on your password. And nobody knows your password, apart from you (not even us).

We know nothing about you: not your name, your recipients, the name, type & size of your files, nor, of course, the subject & content of your messages. We don't even analyse or log your activity.
Better than the old postal service - and definitely stronger than the email industry so far.
AES-256, Salsa20 & Poly1305.

By U2F security key, application or SMS.
Encrypted emails are signed, unencrypted ones contain each a unique code verifiable without an account.

Additionnal encryption of the databases.
Additionnal encryption on every data's transfer.
security policy
Tools sure by design, not by intention: KRYPT7 enforce Strict Security Principles.
The Webmail you know,
securely simple
It's all about continuing to send, receive & organize your emails, as before, with your current address or a new one - easily and simply. Except everything is authentified and encrypted by default: your messages and attachments.
No need to deal with public or private keys, no need to worry if your recipients have a KRYPT7 account, or if they can deal with encryption technology.

Send anyone an encrypted email, with 2Gb encrypted files attached, knowing that, regardless of their system or without any instructions, they will decrypt and read your message. Welcome to KRYPT7.

Encrypted or even in clear:
your choice
Encryption is the security by default - transparent between KRYPT7 users. Even if non KRYPT7 users can effortlessly read and decrypt your encrypted emails, you may want to send them a specific email in clear: not by mistake but by choice - and you have it.

Any recipient can read
& respond your encrypted email
Even without an account, your recipients can read & respond to your encrypted emails, with the same level of security and without any knowledge.
They receive an email with a link: a click and they are redirected to KRYPT7 wich automatically decrypt your message in just a couple of seconds. Your recipients can read it, download the attachments and even reply to you. All without creating an account.

Attach 350Mb encrypted files,
as many as you need to
Because KRYPT7 handles every encrypted email directly, you can encrypt and attach any file up to 350Mb and as many files as you want. Send anyone 2Gb of encrypted files by email. Why not?
Remember, if you choose to send clear emails, the old and frustrating limitations apply: all the attachments and the email content combined can't exceed 8Mb at the most.

Signed emails:
the authentic message from the right person
Encrypting emails allows the senders to sign them: a code stamp is incorporated in the message just before its encryption. A way to ensure that the message you are reading is the exact message sent to you by a verified sender.
To fight spam and phishing even outside KRYPT7, your recipients without an account can verify the authenticity of your encrypted emails, simply by checking their unique codes.

Your own domain
Use directly your actual email address or create any [email protected] to send and/or receive messages.
Reputation, robust globalized infrastructure & verification of domains: your messages will always reach their recipients.
emails only
KRYPT7 is built to reach the people you know and/or those who expect a message from you. Marketing emails are forbidden. As a result, our reputation, and by extension yours, ensure better deliverability.
Instantly contact
your recipients
Encrypted emails between KRYPT7 users don't leave our network: they are served instantly. Outside KRYPT7 environnement, the average delivery time is 10 seconds tops.
Encrypted files storage:
go untraceable
Your files are stored encrypted. So must be their metadata: name, size & type. But it's not sufficient.

Your files are systematically sliced in equal chunks: each one randomly changes their name and type, then is encrypted separately and finally stored along with everyone else's files. The same method is used in reverse to download your files: download & decryption of each chunk, reassembly - again, only in your browser.
And yes, that's also the system used for email attachments.

How can anyone spy on your encrypted files without knowing the decrypting key?
First of all, how can they even find them without their names, types, size, number & order of their chunks?

Optional security boost:
a custom password for each file
By default, as with your emails, a strong derivation of your password is used to encrypt your files. If you want to, you can even increase your security to the highest levels by choosing a specific password for each file.

Lighting fast
The slicing and separate encryption process ensures high privacy & compatibility with all major browsers. That's also guaranteeing speed, because file chunks are working in parallel: in fact, all the encryption or decryption steps are considerably faster than the upload or download phases.

Embrace high security online conduct and generate unique, super strong passwords for each website where you have an account. All the passwords are stored encrypted, securely and easily accessible.
Simple contact manager, connected to your inbox and encrypted - of course.
Update your status at least every 2 weeks, on KRYPT7 or by SMS. If you don't, each recipient of your messages will automatically receive the email intended for them.

A fair price, according of where you are.

Questions & Answers
What do you really know about me?
Your KRYPT7 email address, phone number and username - all data that you can change anytime and of which we don't keep history.
We even don't ask you at all about your name, your postal address, your country, your age, your gender, your profession, your other email addresses, etc. So again, we don't know your name, your recipients, the name, type & size of your files, nor, of course, the subject & content of your messages.
In absolute, we can also know the date of creation of each new content (email sent, file uploaded, etc.). However, we don't analyse or log the activity of users and don't use cookies: more broadly, we never share user data or activity.
Please see all the details in our Privacy Policy, accessible in the footer of all pages.
How safe is the storage of my data?
You data are continuously backed up in 3 identical replica sets, provisioned across 3 distinct data-centers, ensuring your backups are typically just a few seconds behind the operational system (automatic failover in the event of a failure).
Additionally to the systematic end-to-end KRYPT7 encryption, your data are encrypted one more time in transit and also at rest:
  • in transit (SSL): from every point of our systems to another, as well as from and to your browser
  • at rest (AES-256): on storage in our databases, as in our storage servers (all in extra to the encryption of your data themselves).
Which type of emails can I send?
KRYPT7 supports natively HTML emails, which can contain advanced typography, images embedded into the message's content and, of course, have files attached to them. If you send an email in clear, because you might thereby send an email outside of KRYPT7, we're systematically adding to the HTML version a plain-text version, to ensure maximum compatibility with old email clients.
How to use in KRYPT7 an email address on my domain?
First, you will have to create an account with a address. After that, just go to the emails tab, then to the settings tab, and start register your domain for outgoing (the messages that you send) & incoming (the messages that you receive) emails. You must have access to your domain’s DNS records, in order to verify it: just follow the instructions to add the necessary records.
Modification of DNS records can be a scary: if you have any hesitation, contact our support team. And remember, it may take up to 48 hours for DNS changes to fully propagate.
Can I access my emails through POP3 or IMAP protocols?
You can't, due to the highly secured technology used by KRYPT7 to encrypt and decrypt emails right in the user's browser. Therefore, for the same reason, you can't use third-part email software to access your emails. That's also why we work hard to provide you an easy, beautiful and powerful webmail.
Why the files are limited to 350Mb in upload?
As KRYPT7 provides high security encryption & decryption in the user's browser, you can only encrypt & upload files up to 350Mb, due to memory's limitations of all major browsers. Those limitations evolve regularly - so will we, as soon as we can.
How work the encryption of my files, my emails' attachments?
Your files are systematically sliced in equal chunks: each one changes randomly their name and type, is encrypted separately and stored along with every other files of everybody. The same method is used backward to download your files: download & decryption of each chunk, reassemblage - again, all in your browser only.
And yes, that's also the system used for email's attachments.
Why your prices are based on my country?
Simply because $1 doesn't represent the same value everywhere in the world. That's why our prices vary, based on your country's median income.

There are 4 main facturation zone:
- zone 1: $1/mo
- zone 2: $2/mo
- zone 3: $4/mo
- zone 4: $8/mo

Also, if you live in a country with a very low press freedom, the price you'll pay is the lowest possible (zone 1), regardless your country median income, to facilitate the use of tools protecting your privacy.

Countries categories are defined according to the World Bank statistics and the annual Reporters Without Borders report on press freedom. Our system is not perfect, but definitely more fair than the global idea that everyone should pay the same amount - regardless of the cost of their life.
What are the limitations of the beta?
None. The beta will last 6 months, until late August 2019. It will offer us a special period to adapt our services, based on users' returns.
Do you have mobile applications?
Not for the moment, but that's definitely a goal we are working on right now.
Can I submit you a suggestion, a feature request, a simple message?
Of course, don't hesitate to contact our support team: we'll be happy to hear from you.
