Encrypted on this device
How it works

Three steps, then it just works

  1. STEP 1

    Sign in

    With Google or email. That only proves who you are; it never unlocks anything.

  2. STEP 2

    Set your passphrase

    Your device turns it into the key that locks your vault. It never leaves your device.

  3. STEP 3

    Save, sync, open

    Everything is encrypted before it uploads, and decrypted only on your devices.

What you get

One calm place for every secret

Encrypted vault

Keys, passwords and recovery codes as simple label-value pairs. Search instantly; it all happens on your device.

Encrypt any file

Turn a file into a .pcipher file only your passphrase opens. Free, unlimited, nothing uploaded.

Coming soon

Quick accounts

Log in once, then jump between your accounts on any site. Coming with the extension.

Every device

Approve a new device from one you already use. No passphrase typing needed.

Coming soon

Secrets that expire

Pro: have a secret delete itself at a set time, or remind you to rotate it.

Coming soon

Share safely

Send a secret through a link that only opens once, or share a whole vault.

Security in plain words

We built it so we can't look

Your passphrase becomes a key on your device (Argon2id). That key unlocks a random master key, which unlocks your vaults, and each item has its own key. Our servers only ever hold the locked versions.

  • On your device

    Encryption and decryption run in your browser, in compiled, memory-safe code.

  • Modern ciphers

    XChaCha20-Poly1305 for data, Argon2id for your passphrase, X25519 for sharing.

  • Open format

    The .pcipher format and the encryption core are public, so anyone can check them.

FAQ

Questions people ask first

Can you see my passwords or files?

No. Everything is encrypted on your device before it is sent, with a key made from your passphrase. Our servers only ever store scrambled data and never receive your passphrase or your keys.

What if I forget my passphrase?

Use the Recovery Key you saved when you set up your vault. If you turned on assisted recovery, you can also recover through your recovery email after a 72-hour safety wait. If you have neither, nobody can open your vault, not even us. That is what keeps it private.

Is my account password the same as my vault passphrase?

No, and it must not be. Your account password (or Google) signs you in. Your vault passphrase unlocks your data on your device and is never sent to us.

Do I need an account to encrypt a file?

No. The file encryption tool works right in your browser without an account, with no limits. Nothing is uploaded. You get a .pcipher file that only your passphrase opens.

What does Pro add?

More secrets, several vaults each with its own key, encrypted file uploads, scheduled auto-delete, secret links and more Quick accounts. It costs $9.99 a month, less if you pay for 6 or 12 months.
