TricolloDownload

A private place for what matters, protected even from us.

Tricollo encrypts your most important documents and photos right on your device, then makes sure the person you trust can reach them if you ever go silent.

How Tricollo works

Four simple steps stand between what matters and the people who should have it, only when they actually need it.

  1. Create your vault

    Add the documents, photos, and passwords that matter. Everything is encrypted right on your device, before it ever reaches ours.

  2. Choose someone you trust

    Invite a trusted contact. If your vault is ever passed on, it goes to them, and only them.

  3. Set your check-in rhythm

    Tell Tricollo how often to check in with you, anywhere from every few days to once a year. You're always in control of the schedule.

  4. Stay in control

    Answer a check-in when it arrives and nothing happens. Miss too many in a row, and your vault reaches the person you chose.

See it in action, the moment you open the app

Tricollo shows you the encryption happening. Pick any photo or document during setup and watch it get sealed, right there on your device, before it ever touches our servers.

Not even we can read it.

Tricollo is built so that no single party, not your device alone and not our servers alone, can open your vault by itself.

Encrypted before it leaves your device
Every file is sealed on your phone. Tricollo's servers only ever store ciphertext, which is unreadable without your key.
No single piece unlocks it alone
Your vault's key isn't stored anywhere as one whole. It's split across your device, our servers, and your trusted contact, so no single piece, and no single party, can open it alone.
Your trusted contact never holds a spare key
Their piece is generated from a recovery phrase only they see, in their own browser. It's only ever used if a handoff genuinely happens.

Everything a vault should be

Serious encryption, without making you think about encryption.

Zero-knowledge encryption

Files are encrypted on your device before upload, so no single party, including us, can open your vault alone.

Flexible check-ins

Pick any rhythm from a few days to a year, and change it whenever your life does.

Trusted contact handoff

Invite the people you trust most. They only ever get access if you go silent, never before.

Face ID & Touch ID lock

Your vault stays locked behind your device's biometrics, on top of end-to-end encryption.

Push, email & SMS reminders

Never miss a check-in by accident, with reminders that reach you on every channel you enable.

Built for iOS
