The platform

The estate your family can actually find.

GuardKin is one encrypted vault, seen three ways — by the family who builds it, the advisor who coordinates it, and the people who must act when it matters. Sensitive content is sealed with keys our servers have never held, so the right truth reaches the right person at exactly the right moment.

One vault

three lived surfaces

Zero-knowledge

Audit chain

every access, tamper-evident

The three surfaces

One encrypted vault, seen three ways. Nothing leaks between them.

GuardKin is not a folder of documents. It is one vault with three lived views — and the boundary between them is enforced by cryptography at the data-model level, not by a permission an admin can flip.

Client vault

The family builds the map

A living record of accounts, documents, property, contacts, and personal letters — encrypted in the browser before anything is stored.

  • Held-away assets, insurance, and digital life in one place
  • Personal letters sealed until the moment they are meant for
  • A readiness meter that shows what is still missing
Advisor view

The advisor sees the shape

Provisioned only under client consent, the advisor sees the estate’s structure they are entrusted to coordinate — never the sealed contents.

  • Planning-scope visibility: gaps, outdated documents, missing executors
  • Consent-scoped — the client grants and revokes in one click
  • No personal letters, no account numbers, no document contents
Crisis mode

The right people, the right access

On incapacity or death, designated people gain exactly the access they were granted — and every event is written to an immutable audit chain.

  • Executor designation set calmly, long before it is needed
  • Crisis-mode access that unseals only what was meant for them
  • A tamper-evident record of every unlock and every view
How it works

One vault, carried across a life.

The same record follows the family from a healthy day to the day it is needed most — surfacing the right thing to the right person at each stage, and only then.

01
Healthy

Build it calmly

The family seals accounts, documents, property, and letters. The advisor is invited to the planning-scope view. Readiness climbs as gaps are filled.

02
Incapacity

Step in, scoped

A designated person gains the precise access they were granted — enough to act, never more. The boundary holds even here.

03
At death

Surface what was sealed

Crisis mode unseals only what was meant for each person. The letter to a daughter reaches her; the account list reaches the executor.

04
Settling

Settle without archaeology

The executor works from a map, not a mystery — every account, contact, and instruction in one place, with an audit trail of every access.

The feature spine

The capabilities behind the calm.

Six capabilities carry the whole product — from the moment a family starts the vault to the moment an executor settles the estate.

See the cryptographic boundary

The estate vault

Accounts, documents, property, contacts, and letters — structured, searchable, and sealed client-side.

Held-away capture

The assets and digital life a planning tool never sees: outside accounts, insurance, subscriptions, devices.

Executor designation

Name who acts, and exactly what they may reach — decided calmly, long before the moment arrives.

Crisis mode

On incapacity or death, scoped access opens for the right people — unsealing only what was meant for them.

Immutable audit chain

Every invite, unlock, and view written to a tamper-evident, signature-linked record. Trust, but verify.

Right to unlink

The client revokes any access in one click. No firm contract, court, or admin setting overrides it.

Trust & security

The boundary is the product. It is enforced by cryptography, not policy.
