Three steps. Total peace of mind.

Set it up once. Semma quietly watches over everything, for as long as you live — and beyond.

1
🗄️

Build your vault

List your digital assets — crypto wallets, bank accounts, cloud photos, domains — and leave encrypted instructions for each one. Everything is sealed in your browser before it ever reaches our servers.

💓

Stay connected

Semma checks in with you on your schedule — a single tap confirms you're fine. Miss several check-ins and our escalation protocol begins, carefully and gradually.

🕊️

Legacy delivered

Only when the protocol completes do your chosen people receive the keys to unlock your instructions. Nothing lost. Nothing left in limbo. Your story, handed over with care.

Built like a bank. Feels like a promise.

🔐

Zero-knowledge encryption

Your secrets are encrypted on your device. We store only sealed boxes — we couldn't peek inside even if we wanted to.

The living switch

A gentle check-in system that adapts to your life. Travelling? Pause it. Back home? One tap and Semma sleeps again.

👥

Guardians you choose

Assign different assets to different people. Your brother gets the crypto keys, your best friend handles your socials.

🛡️

False-alarm proof

Multi-stage verification and optional waiting periods make sure nothing is ever released by accident.

We guard the box.
Only you hold the key.

Be there from the beginning.
