How it works
Set it up once. Rest easy.
- 1
Create your private vault
Choose a passphrase only you know. Everything inside is encrypted with it — even we can’t read it.
- 2
Add your wishes
Messages, documents, directives, and the practical details your family will need.
- 3
Choose who gets what
Assign each item to the right people — shared now, or only after a verified passing.
- 4
Delivered when it matters
Your wishes reach exactly the right people, after verification. Not a moment sooner.
Private by design
Your most personal things, truly private
KinCoffer is built so that no one but you and the people you choose can ever read what’s inside — not even us.
- Zero-knowledge encryption. Your vault is encrypted with your passphrase. We store ciphertext we can’t read.
- You hold the only key. Recovery keys go to trusted contacts you choose — never to us.
- Two-factor authentication. Protect your account with an authenticator app.
- Always yours. Export everything as a decrypted archive, or delete your account, anytime.
Released only when it’s truly time.
Nothing is shared until a passing is verified through proof-of-life checks and confirmation from the executors you’ve named. Your privacy holds — right up until the moment your family needs you most.
