The first health app your own AI agent can read. Claude Code, Hermes, OpenClaw — connected over MCP, decrypted only on your machine. We only ever store ciphertext.
Your AI can read your health. We never can.
Vaultbeat is the first health app on the App Store built to be read by YOUR own AI agent — Claude Code, Hermes, OpenClaw, or anything that speaks MCP. Sleep, cycle, heart, activity: end-to-end encrypted on your iPhone, decrypted only on hardware you control.
FOR YOUR AI
• Plug your health into any MCP-capable agent — the same way agents connect to files and databases
• Your agent sees sleep stages, cycle patterns, HRV trends, symptoms — and reasons across them
• It can log meals, lifts, weight and notes back for you, so tracking is a sentence instead of a form
• Decryption happens on YOUR machine only. No AI runs in our cloud. We store ciphertext, nothing else.
FOR THE TWO OF YOU
• Share sleep, cycle, weight, hydration with your partner — each category its own switch, controlled by the data owner
• See each other's night at a glance; know when to be gentle
• Dynamic Island shows when your partner last got up
• One membership covers you both
PRIVATE BY PHYSICS, NOT BY PROMISE
• Curve25519 + AES-GCM end-to-end encryption, keys in your personal iCloud Keychain
• Cycle and symptom data: there is no readable copy on our side to leak, sell, or hand over
• No ads. No data brokers. We couldn't train on your data even if we wanted to — we only have ciphertext.
WHAT VAULTBEAT TRACKS
Sleep (stages, heart rate), menstrual cycle with ovulation detection, 39 symptom types, weight, hydration, activity, resting heart rate, HRV, wrist temperature, workouts, mindfulness, VO2 Max — from Apple Health and Apple Watch. Plus two things Apple Health has no room for, kept by hand or by your AI: a strength training log (exercises, sets, reps, weight) and a plain-text food log.
MEMBERSHIPS
Recording on your iPhone is free forever, and on Free nothing leaves the phone. Vaultbeat Pro keeps your encrypted history in the cloud, where your own AI agent (MCP) and your partner can read it — one membership covers a paired couple. Pairing your first AI server starts a three-day trial. Monthly, yearly, or one lifetime purchase.
