Share Your Rest.
Own Your Data.
See how your partner slept — without asking. Vaultbeat syncs both partners’ Apple Health data in the background, end-to-end encrypted so we can never read it. Your own AI agent can, though.
Share sleep data with your partner — not with us
Vaultbeat is built on one rule: your health data belongs to you and the people you choose — your partner, and your own AI.
Zero-Knowledge Cloud
Powered by Curve25519 end-to-end encryption. We route your encrypted health metrics, but we never see them. Only you and your authorized connections hold the keys.
Intimate Partner Sync
Not just sleep: overnight heart rate, menstrual cycle, weight, water, symptoms. Each category syncs in the background, only if its owner switches it on — and partner sharing is free forever.
AI Agent Integration
Connect Claude Code, Hermes, OpenClaw, or any MCP-capable agent through a local MCP server. The cloud ships ciphertext only — your data is decrypted only on your machine. Set up your agent →
Did she sleep well last night?
An Apple Watch only shows its wearer’s sleep — there is no built-in way to see how your partner slept. Vaultbeat closes that gap: you both install the app, and each night’s sleep — duration, stages, overnight heart rate — syncs automatically from Apple Health to the other’s phone, encrypted on-device before it ever leaves.
No more texting “did you sleep?” across time zones. You wake up, open Vaultbeat, and the answer is already there — recorded while you both slept, without either of you lifting a finger. For long-distance couples, a daily worry becomes a glance.
One Apple Watch between the two of you? It still works. If a partner sleeps with just an iPhone, Vaultbeat can infer their sleep on-device from Motion & Fitness — and when a Watch is present, it automatically prefers the Watch’s measured sleep stages.
Your AI can read your health — we never can
Vaultbeat is the only health app on the App Store designed to be read by your own AI agent. Pair a machine you own by scanning a QR code, and Claude Code, Hermes, OpenClaw — anything that speaks MCP — can query your sleep, heart rate, cycle, and weight history the same way it queries your files.
The cloud only ever stores ciphertext. Your paired machine downloads it and decrypts it locally, with a key that never touches our servers. Sensitive categories — cycle, symptoms, notes — are individually opt-in and off by default.
