Kinship Vault - Zero-knowledge document and photo vault

Hey Product Hunt 👋 I'm Abhishek. I build alone, and I've been working on Kinship Vault for the better part of a year. It started with a question I couldn't shake. My dad had a folder. Actual manila, actual paper. Passport, insurance, the deed, a note about what to do. Everyone in the family knew where the folder was. That folder was the most reliable piece of infrastructure in our lives, and nothing I own today comes close to replacing it. My version is a mess of screenshots, a few PDFs in email, and a drawer. If I lost my phone tomorrow, or if something happened to me, nobody could find anything. I suspect that's true for most of you reading this. So I built the digital folder. Two rules I refused to break. 1. I can't read your documents. By architecture, not by policy. There's no account, no password and no email on file, so there's nothing to phish and nothing to breach. A 256-bit master key is generated on your device and wrapped by the Secure Enclave using ECIES, a hardware key that physically cannot leave the chip. Every document gets its own key derived via HKDF, then gets encrypted with AES-256-GCM. If someone served me a subpoena, I'd have nothing to hand over. That's the entire point. Any app can claim "we take privacy seriously." The test is whether they could betray you. I've made it so I can't. 2. Recovery belongs to people, not to a support inbox. Zero-knowledge usually means "lose your key, lose everything," which is why normal people don't use it. So recovery is something you design in advance: A BIP39 passphrase you write down once Split your key across people you trust, where any 3 of 5 can bring you back A quiet time-based safety net for the people who'd need it most Your trusted contacts never see inside the vault. Each one holds a fragment that on its own opens nothing. What it actually does day to day Reads what you already carry. Point the camera at a passport, licence, health card or tax form and it extracts the fields on device across 100+ document schemas worldwide. On Mac you drag the file in. Watches the dates so you don't. Reminders at 90, 30, 7 and 1 day before anything expires. Emergency mode. Blood type, allergies, ICE contacts and travel ID readable in one tap without unlocking the rest. Digital legacy. Final wishes, which accounts to close or memorialize, and sealed letters that Face ID locks and I genuinely cannot read. New: a real native Mac app. Proper sidebar, split view, menu bar commands, ⌘N and ⌘L, drag and drop, Mac style preferences. Not an iPad app in a window. One purchase covers iPhone, iPad and Mac. Three things I'd rather you heard from me than found out later Macs have no document scanning camera flow, so you drag files in instead. macOS gives apps no way to block screenshots, so when the Mac is the device showing a pairing QR, that QR isn't screenshot protected the way it is on iOS. The app warns you on screen. The Dead Man's Switch is iPhone and iPad only, because it depends on check-in reminders a desktop app can't reliably send. Pricing : $1.99 a month or $14.99 a year. There is a lifetime option at $39.99 🎁 For Product Hunt: Lifetime Premium at 62% off, $14.99 instead of $39.99. Redeem on your iPhone or iPad, then open the Mac app and hit Restore Purchases. It unlocks everywhere on the same Apple Account. (Apple's Mac redemption path needs macOS 15 or later, so redeeming on the phone is the reliable route for everyone.) I'll be in the comments all day and I want the hard questions, especially about the crypto. Tell me what would make you actually trust an app like this with a copy of your passport, because that answer is the roadmap. Read more on : https://kinshipvault.app
