Eleven kinds of information. One encrypted file.
CofferShield is not a password manager with extras bolted on. Each section below is modelled properly — its own fields, its own layout, its own rules about what may be printed — because an insurance policy and a seed phrase do not ask the same questions.
Five kinds of record, not one.
A login is not a seed phrase and a seed phrase is not a software licence. CofferShield keeps five distinct kinds of password record, each asking for the fields that kind actually needs, and masks the sensitive ones until you choose to reveal them.
- Logins, seed phrases, PINs, licences and security answers — each with its own fields
- Sensitive values masked by default; revealing one is a deliberate act
- Search across everything without decrypting anything to disk
- Auto-lock on a timer you set, plus a session PIN for short absences
The paperwork, not just the passwords.
Deeds, policies, certificates, powers of attorney, the scan of the safe-deposit key. They go into the same encrypted file as everything else, so there is one thing to back up and one thing to protect.
- Encrypted inside the vault file — not a folder of loose PDFs
- Opens and previews without writing a decrypted copy to disk
- Attach a document to the record it belongs to, so it is found in context
- Backups carry the documents with them
What your family will actually need to find.
Most estate information is not secret. It is scattered — across a solicitor’s office, a drawer, an inbox and somebody’s memory. CofferShield gives it one place, in the order a person would need it.
- Where the will is, who holds it, and when it was last reviewed
- Executors, solicitors, accountants — with how to reach them
- Instructions in your own words, attached to the records they concern
- Printable heir sheets, one per person you name
The mismatch nobody checks.
A pension names one person. The will names another. Whichever is more recent is not the one that wins — the beneficiary designation usually does, and it usually has not been looked at since the account was opened.
- Every account with a named beneficiary in one list
- Flags where a designation and your will disagree
- Records when each was last confirmed, so “I think it’s fine” becomes a date
- Nothing is sent anywhere to do this — the check runs on your machine
For the case where you are still here, but cannot answer.
The harder case is not death. It is the six weeks where someone else has to run your life and does not know the first thing about it. This is the section people skip and later wish they had not.
- Healthcare directives, and who holds a copy
- Powers of attorney — financial and medical, kept apart
- The bills that keep arriving and how each one is paid
- A wallet card with your healthcare contacts, sized to be cut out
Thirty-six fields, because a policy has thirty-six answers.
Insurance is where under-modelled software shows: a life policy and a home policy do not ask the same questions. CofferShield keeps six categories and thirty-six built-in fields, and lets you add your own where your policies do not fit ours.
- Six categories, each asking only its own relevant fields
- Sensitive numbers masked, and excluded from anything you print
- Custom fields and custom categories, scoped to where they belong
- Renewal dates in one view, so nothing lapses quietly
What you own, what you owe, and where it is.
Nine kinds of asset and twelve kinds of debt, each with the fields that kind needs — a crypto holding asks about a wallet, a property asks about an address, a cash account asks about an institution.
- Nine asset types and twelve kinds of debt, fully modelled
- Only the last four digits of any account number are ever stored
- Custom fields and custom types, with per-type layouts
- Optional price refresh for shares and crypto — off until you switch it on
One page, printed, in a drawer.
The most reliable technology in an emergency is paper. CofferShield prints a single sheet with what someone needs in the first hour, an heir sheet for each person you name, and a wallet-sized card for your healthcare contacts.
- Emergency access sheet — first-hour information, one page
- Heir sheets, one per named person, containing only their part
- Wallet card cut to credit-card size for healthcare contacts
- Fields you mark sensitive are never printed, by rule not by habit
The state of everything, at a glance.
Net worth, what has changed, what is missing, and what needs looking at. It is the screen that turns a filing system into something you actually open.
- Net worth across assets and liabilities, updated as you edit
- What is incomplete — the fields you meant to come back to
- Renewals and reviews coming up
- Everything computed locally; nothing leaves the machine to produce it
The parts you should not have to think about.
AES-256-GCM
Authenticated encryption, so the vault detects tampering rather than quietly decrypting something altered.
600,000 rounds
PBKDF2-SHA256 at the current OWASP recommendation, which is what makes guessing your master password expensive.
No server, no account
Nothing to sign up for, nothing to breach, nothing to be sold with the company.
Backups you control
An encrypted .coffer file in a folder you pick, on a schedule you set, with a rolling set of the most recent copies.
Print rules, enforced
Fields marked sensitive are excluded from every printed sheet by rule, not by remembering.
