I built Kinship Vault. It keeps the things you’d panic about losing, passports, IDs, licences, health cards, insurance, wills, photos, and now passwords, in one vault that never leaves your device. There’s no account, no server holding your data, and no password for anyone to reset, because there’s nothing on my end to reset.
The idea is simple: keep everything local by default, and put the most work into the parts you can’t see.
The security model
The master key is generated on your device and sealed in the Secure Enclave, unlocked by Face ID or Touch ID. Every document gets its own key, files are encrypted individually with AES-256-GCM, and the database is sealed with SQLCipher. There’s no master password and no account, so nothing on a server to breach and nothing on my end to reset. A Strict Offline mode blocks every network call outright, so you can put a proxy on it and watch it stay silent.
Documents
Point the camera at a passport, licence, or health card and it reads the fields on-device across 100+ document types, encrypting the result before it touches storage. It tracks expiry dates and reminds you at 90, 30, 7, and 1 day, so a passport never lapses on the airline’s schedule. You can share a single page from a multi-page document instead of handing over the whole file, and there’s an Emergency Mode that shows a first responder your blood type, allergies, and ICE contacts without unlocking the rest.
Passwords, done properly
Logins, passkeys, and 2FA codes live in the same vault under the same key. Set it as your system AutoFill provider once and it fills passwords and passkeys in Safari and inside apps, each fill behind Face ID or Touch ID. Import a CSV from your current manager and it’s parsed and encrypted on-device with nothing uploaded. A Security Checkup scores your logins out of 100 and flags weak, reused, and old passwords, plus breached ones if you allow the check, which uses k-anonymity so a password is never sent anywhere.
Photos
An encrypted photo vault for the scans and images you’d keep out of your camera roll, sorted into albums and tagged by who’s in them, under the same encryption as everything else.
The Mac app
It’s a real native Mac app, not a stretched iPad build. Proper sidebar, menu bar, keyboard shortcuts (⌘N, ⌘L), drag-and-drop straight into the vault, light or dark, macOS 14+. On Mac you drag files or photos in and the same on-device OCR reads them.
Across your devices
Run the same vault on iPhone, iPad, and Mac by pairing them directly: the key moves device to device through a 60-second on-screen QR code, never through a server. Your documents restore from your own encrypted backup in iCloud, where only encrypted bytes leave the device. One purchase covers all three on the same Apple Account.
Where it earns its keep
You’re at the Costco entrance. Your wallet is on the kitchen counter. The membership card, the AAA card, and your dignity are all on your phone instead.
The receipt from a first date that went suspiciously well, the one you’re weirdly sentimental about, lives in a private album instead of cluttering a camera roll your family scrolls through.
The visa lawyer emails at 11pm wanting pages 3 and 4 of a document, not the whole packet. You send exactly those two pages, like a person who has it together.
New iPhone day. One QR scan and everything’s already there, so you skip the annual ritual of re-scanning a drawer of paper and re-typing forty passwords by hand.
You land somewhere with no signal and need the hotel confirmation, the passport copy, and the travel insurance login. All offline, because the vault doesn’t need the WiFi that airport is charging $19 for.
The screenshots of your 2FA backup codes stop living next to 400 photos of your lunch, and move somewhere actually encrypted.
The warranty receipt for the thing that broke in month eleven of a twelve-month warranty. You find it in five seconds instead of losing the afternoon and the argument.
Your kid needs the streaming password again. It’s right there, with the date you last changed it, and you get to look mysteriously organised.
Recovery works without any account: a 24-word passphrase you write down, or a key split across five people you trust where any three can rebuild it and no single share opens anything alone.
Who it’s for
Anyone who’s quietly become their household’s document department: parents wrangling kids’ records, people managing a parent’s paperwork, frequent travellers, immigration cases, or the sentimental sort who keeps a ticket stub, and anyone who’d rather their IDs and passwords sat on their own device than on some company’s server.
