For the things you'd send
by registered letter.
A will. A custody agreement. The bank details for a house sale. Write it, attach something if you need to, and it is sealed before leaving your device, opened only by the person you meant, who proves it with their own bank credentials.
Free to start. No subscription. The person receiving doesn't need an account. Setting up takes about three minutes once, then you write and send.
The moments people use this for.
After a death
The will, the bank letters, the account numbers, going to siblings who live in three different cities, at the worst possible time to be careless.
When a family separates
A settlement clause, a custody schedule, school letters. Things you need to send to someone you're no longer sure you can send anything to.
Helping a parent
Their medical papers, their pension letters, their power of attorney. You end up handling private information that was never yours, and it deserves the same care.
Bank details for a house sale
The single most dangerous line of text most people ever send. Account numbers sent by ordinary email get read, altered by a digit, and paid into the wrong place. Sealed, and opened only by someone who proved who they are.
Passwords and account numbers
The household passwords for your partner. A code for a colleague. An insurance number, a policy reference, a login for a relative who's helping you. No attachment involved, just words that shouldn't be lying around in two inboxes forever.
Health and money, in writing
A diagnosis you're relaying, a therapist's letter, financial statements, a passport copy for a relative helping with forms. Things you'd never leave face-up on a table.
Familiarity
You've already done the hard part a hundred times.
If you've filed your taxes, checked your prescriptions or logged into your bank online, you already know how this works. Your recipient identifies themselves the same way: with their own bank credentials.
Nothing to install
No app, no password to invent, and no account to create before opening something. It's the familiarity of a bank login, applied to a message instead of an account.
If you've used Suomi.fi Messages, you know the feeling
A secure message from an authority that you open by identifying yourself. Reassuring, and previously something only institutions sent to you. This is that, except you're the one sending, and you can send to anyone.
The same login you already trust
Bank credentials through the Finnish Trust Network, or a lighter method when that fits.
Bank credentials
Strongest option for anything serious.
Code by text
When bank ID isn't available.
Agreed PIN
Something you've already shared in person.
How sending works.
Write it, and attach if you need to
Like any email, except it's sealed on your own device before it goes anywhere. Most people are sending words.
Choose how they prove it's them
Their bank credentials for anything serious. A code by text message, or a PIN the two of you agree on, when that's enough.
They open it, and you can see they did
The message arrives in their normal inbox. They identify themselves, and it unseals on their device. You can see when it was opened.
You can take it back.
Withdraw a message
Sent it to the wrong sibling, or realised the account number was wrong? Withdraw access and it stops opening.
Give it a lifetime
Set a message to stop working after a few days, or to open only once. Useful for a password, or an identity copy that only needed to be seen a single time.
Recovery
If you lose your phone.
When you set up your account you get a recovery phrase: twenty-four words you print once and keep somewhere safe, next to your passport or your insurance papers.
Those words restore your access
Lose your phone, replace your laptop, or simply come back after two years: the phrase brings you back. Without them, nobody can get into your messages. Not a thief, and not us either.
That's the trade. We can't read your messages, which also means we can't let you back in if you lose both your devices and your recovery phrase. Print it. Put it somewhere real.
Print it once
Keep the recovery phrase next to the papers that already matter.
Twenty-four words
Generated on your device when you set up.
Offline by design
We never see it, and we can't recreate it.
Why we can't read your messages.
Three things, in plain language.
Sealed before it travels
Your words, and anything you attach, are sealed on your own device. What arrives on our servers is sealed data we have no way to open, so a break-in at our end reveals nothing readable.
Built to hold for decades
The sealing uses ML-KEM-1024, a post-quantum standard chosen by NIST. It's designed to hold even against the far more powerful computers expected in the coming decades, so something copied today can't be opened years from now.
Honest about the one thing we hold
We keep half of each message's unlock, which lets you withdraw a message after sending it. On its own, it opens nothing.
Pricing coming soon.
We are finalizing our seat and identity verification pricing. Contact us if you have questions about access.
Suoja means
shelter.
We're a Finnish company, your messages are stored on European infrastructure, and they stay under Finnish and EU law.
Questions.
Does the person receiving it need an account?
No. They open a link in the inbox they already use, identify themselves, and read it. If they'd like their own account later, they can, but nothing requires it.
What if they're not Finnish, or don't have bank credentials?
You can send a code to their phone by text, or agree a PIN with them another way (over the phone or in person). Bank verification is the strongest option, not the only one.
Is this legally valid, like a registered letter?
It gives you something ordinary email cannot: a record of who identified themselves and when they opened it. Whether that satisfies a particular legal requirement depends on the requirement, and we won't pretend otherwise.
What can you see?
Who you sent to, and when it was opened: we need that to deliver it and to tell you. Not your subject line, not your message, not your attachments.
What if I stop using it?
You can delete your account and your messages. Nothing about the free tier obliges you to keep coming back.
Keep it for the day you need it.
Most people set up an account long before they use it seriously, then remember it the week something important has to be sent. Setting it up takes a few minutes and costs nothing.
