How Tricollo works
Four simple steps stand between what matters and the people who should have it, only when they actually need it.
Create your vault
Add the documents, photos, and passwords that matter. Everything is encrypted right on your device, before it ever reaches ours.
Choose someone you trust
Invite a trusted contact. If your vault is ever passed on, it goes to them, and only them.
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.
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.
Your vault's key, split three ways. No single piece opens it alone.
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
A native SwiftUI app designed around iOS conventions: fast, familiar, and easy on the battery.
