## What is Vaultbeat?

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 (free, forever)
• 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 whether your partner is still asleep

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 and partner sharing are free forever. Connecting an AI server is open on every plan, and pairing a machine starts three days of full agent access. Vaultbeat Plus unlocks full history and trend charts; Vaultbeat Pro keeps the AI agent interface (MCP) going after the trial — monthly, yearly, or one lifetime purchase.

## Version history (last 4 releases)

### 1.2.3 — 2026-08-19

Connect your AI without a subscription. Pair a computer and you get three days of full agent access — counted from the moment your server actually connects, not from when you installed. Settings shows how long is left, so it never runs out without warning.

Also in this release:
• Connecting your AI now shows the command that actually prints the QR code — the old steps started with one that prints nothing at all
• The scanner names that command too, if nothing has been scanned for a while
• After connecting, the app tells you it is still sending your history, and resumes that transfer when you come back instead of only on a fresh launch
• The cycle prediction card no longer looks like a locked paid feature on days there is nothing to predict yet
• Settings now tells you when Apple Health itself is unavailable, instead of reporting it as a permission you declined
• Plus now names the trends it unlocks — sleep, cycle and weight
• The weight card no longer claims you have never weighed in when the real reason may be that Apple Health access was declined

### 1.2.2 — 2026-08-12

• Your night card now appears on its own at bedtime — no need to open the app
• Your night card now shows when your partner last woke up, instead of guessing whether they're asleep
• See and remove the AI servers you've authorized, right from Settings
• Turn on Settings › Allow AI to update Apple Health, and weight your AI logs reaches Apple Health — even on days you already weighed in
• Tap your food card for the day in full — calories and protein, what you burned, and how the two line up with your weight
• If your scale measures body fat, BMI or lean mass, your AI can now read those too
• A stuck upload can be cleared in one tap from Settings
• Past releases are now readable in the app — Settings › What's New
• Other stability and sync fixes

### 1.2.1 — 2026-08-04

Tether is now Vaultbeat — new name, same vault. Plus:
• Log your strength training sets, synced privately and readable by your AI agent
• See exactly which plan you're on, with your renewal date, in Settings
• Nights estimated from motion are now clearly labeled
• A proper welcome for new couples
• New About MCP guide in Settings — everything your AI can see, and how to connect it
• Sharper error messages when connecting your AI agent, and a new doctor self-check in the MCP server
• Sync reliability fixes

### 1.2.0 — 2026-07-16

No release notes.
