Why Confidesk

Private because only you can unlock the key to access it.

Most email asks you to trust the provider with everything. Confidesk is built so that trust isn't required — your data lives on our servers as scrambled gibberish, and the passphrase that unlocks it never leaves your device.

Encrypted in your browser

Mail and files are encrypted on your device before they leave it, using modern elliptic-curve encryption. We move the data — we can never read it.

Only your passphrase opens it

Your key is unlocked in memory, only while you're signed in, only by a passphrase that never leaves your device. There is no reset and no back door.

Nothing tracks you

Messages render in a sealed sandbox and remote content stays blocked, so reading a message tells the sender nothing — no read receipts, no tracking pixels, no hidden code.

Contact form & Secure Send

Share a contact form so anyone can send you an encrypted message — no account needed — and use Secure Send to deliver a one-time encrypted message to anyone.

Why free email can't make this promise →

More than email

One private place for everything.

Mail is just the start. The same encryption protects your files, passwords, and conversations — all readable only by you.

Encrypted mailbox

Send and receive mail encrypted to your key — readable only by you, on your device.

Files & storage

Keep documents in encrypted storage — decrypted only when you open them, in your browser.

Notes

Encrypted notes in Markdown, plain text, or rich text — rich notes download as real .rtf files that open formatted in compatible applications.

Documents

A full document editor for writing that outgrows a note — and no lock-in: every document exports from your device to PDF, Word, and EPUB.

Password vault

A built-in KeePass (.kdbx) manager for your passwords — the same file opens anywhere.

Private chats

End-to-end encrypted one-to-one and group chat — sealed separately for each person.

Safe file preview

Open PDFs, documents, images, and video inside a sealed frame — nothing runs, nothing tracks.

Your own domains

Advanced accounts run several of your own identities, aliases, and custom domains.

Signing in

Two secrets, two jobs.

Every sign-in uses a login code we email you and a passphrase we never see. One proves it's you; the other unlocks your key — right in your browser. Any standard TOTP authenticator app can take the place of the emailed code.

1

Enter your username

You start the sign-in from any device, any browser.

2

Type the emailed login code

A short, one-time code goes to your external address — proving you control it.

3

Unlock with your passphrase

Your encrypted key reaches your browser and your passphrase unlocks it, in memory only.

Unlock your mailbox

Your passphrase decrypts your key on this device. We never receive it.

The whole machine, opened up — how Confidesk is different →

If a service can recover your data after you forget your password, someone other than you can open it too.

Confidesk can't recover yours — and that's the proof. No reset link, no recovery code, no back door: your passphrase is the only key, and it lives in exactly one place, your memory. That's the trade for data only you can read. For certainty rather than a promise, you can remove your key from our servers entirely and provide it yourself at each sign-in.
