What it is

A vault for the things only you should be able to seal — and only the right people should ever open.

EternaCapsule is built on a single, uncompromising idea: the keys belong to you. Not to a server. Not to a court order. Not to us. Memories are encrypted before they ever leave your device. Time-locks are written into mathematics, not promises. Executors are verified cryptographically — and only when the moment is true.

Three Pillars
i.

Memory Capsules

Photos, video, audio, letters. Sealed with AES-256-GCM. Released by time, by trust, or by the verified passing of the keeper.

ii.

Digital Will & Executors

A Shamir threshold of trusted hands. No single executor holds the key — only their cooperation can turn it.

iii.

Zero-Knowledge Safe

Identity, financial, legal, seed phrases. Encrypted on-device. We cannot read it. We cannot help anyone else read it. That is the point.

“The keys belong to you.
We hold nothing we could betray.”

— Founding principle
Early Access

A small list. Quiet updates.
Founding access when we open.

No marketing. A short note when each pillar is ready, and an invitation when the doors open.
