Support & FAQ

Vaultbeat is the only health app on the App Store designed to be read by your own AI agent. It speaks the Model Context Protocol (MCP), so it plugs directly into Claude Code, Hermes, OpenClaw, and any other MCP-capable agent — the same way those agents connect to files or databases, they connect to your health. Your Apple Health data — sleep, cycle, heart, activity — syncs end-to-end encrypted to the cloud, and a machine you own decrypts it locally and reasons over it. No AI runs in our cloud; we only ever store ciphertext. Your AI can read your health. We never can.

Yes — that's exactly what Vaultbeat is built for. Apple's built-in Health Sharing shows limited summaries and trend highlights; Vaultbeat syncs the actual sleep data — bedtimes, wake times, and Apple Watch sleep stages — both ways, end-to-end encrypted. Each partner installs Vaultbeat on their own iPhone and pairs once with an invite code; what gets shared is chosen per category, from the data owner's phone. Partner sharing is free on every plan.

No. Every record is encrypted on your iPhone before upload — Curve25519 key agreement (X25519 ECDH + HKDF-SHA256) with AES-GCM encryption — and our servers store and route ciphertext only. We hold no decryption keys and no decryption capability, so we cannot read your health data even if we were asked to. That is a property of the architecture, not a policy: your AI can read your health — we never can. The full detail is in the Privacy Policy.

Yes — Vaultbeat is an iOS app, and each partner runs it on their own iPhone with their own account. That's what makes end-to-end encryption between two people possible: each phone holds its own keys. You can also use Vaultbeat entirely solo; partner features simply activate when a second iPhone joins.

No, a Watch is optional. With an Apple Watch, Vaultbeat records real sleep stages (core, deep, REM). Without one, the app asks for Motion & Fitness permission and infers sleep from periods of phone inactivity — that inference runs entirely on your device, and raw motion data never leaves your iPhone. When both sources exist, Vaultbeat automatically prefers the stage-detailed Watch data.

Install the open-source Vaultbeat MCP server (Python 3.11+) on the computer where your agent runs, then pair that machine from the iOS app: Settings → Data & AI → MCP Server, and scan the QR code the server displays. For Claude Code the install is a single claude mcp add command; from then on your agent queries your health history through standard MCP tools, and decryption happens locally on that machine. Step-by-step instructions and the copy-paste commands are on the MCP setup page. Requires the Vaultbeat iOS app and the Pro plan.

Pro: $9.99/month, $79.99/year, or $149.99 lifetime. Pro includes everything in Plus ($2.99/month · $19.99/year), which adds full history and trend charts. The Free tier covers health recording and partner sharing — partner sharing is never paywalled.

Billing is handled by Apple. Open iOS Settings → [your name] → Subscriptions, or in Vaultbeat go to Settings → Membership. Cancelling stops the next renewal; your plan stays active until the end of the period you already paid for, and your data and the free features are unaffected.

Three things to check, in order: ① Both phones are signed in and the partner bond is active (Settings → Partner). ② The data category you expect is actually shared — sharing is per-category, and the toggle lives on the data owner'sphone, not yours. ③ Give it a moment after your partner's phone syncs: data flows iPhone → cloud → your iPhone, and iOS schedules background uploads on its own rhythm. Opening the app on your partner's phone forces a fresh sync. If it still fails, email us with both iOS versions.

Sleep quality depends on the source. An Apple Watch records real sleep stages (core, deep, REM); an iPhone alone infers sleep from motion and produces a rougher, longer-looking record. Vaultbeat automatically prefers stage-detailed Watch data when both exist. If you don't wear a Watch, expect approximate sessions — and if a third-party sleep app also writes to Apple Health, its data can add noise. You can review every source in the Health app under Browse → Sleep → Data Sources.

No, as long as iCloud Keychain is on. Your decryption key lives in your personal iCloud Keychain and follows you to the new device; sign in with the same Apple ID and your history decrypts in place. If iCloud Keychain was off when you set up Vaultbeat, the key existed only on the old phone — that's why the app warns about it at setup. Check Settings → [your name] → iCloud → Passwords and Keychain.

In the app: Settings → Account → Delete Account. This removes your encrypted health blobs, envelopes, device records, and partner relationships from our servers. Data already on your own devices (or a machine you paired) stays yours — we can't reach into your hardware, by design. Details in the Privacy Policy.
