## What is Syncky Health?

Syncky Health moves your Apple Health data to the places you run, and lets them write back.

YOUR SERVERS
Add any HTTP endpoint: Home Assistant, n8n, Node-RED, InfluxDB, a server built for another Health export app, or your own script. Pick the data types and the format: Syncky JSON, the JSON format other Health export apps use, CSV or InfluxDB line protocol. Pick the authentication: Bearer, header or Basic, with optional HMAC request signing. Syncky sends new records straight from your iPhone whenever iOS wakes it, and your server can answer with entries to write into Health.

YOUR AI AGENT
Pair an agent running on your computer or server by scanning a QR code. Data travels through Syncky Relay end-to-end encrypted. Relay stores your health data only as sealed messages, for up to 7 days, and never has the key; its own short notices to your devices (a member joined or left, a service notice) are not encrypted. Your agent is your own program; no AI service gets your data from Syncky. You choose which types each agent receives and may write back: weight from a smart scale, water, caffeine, anything you allow.

The agent generates the QR and pairing code locally; confirm the displayed code on your iPhone to complete proof-based pairing. HPKE Auth authenticates encrypted client envelopes from paired senders; Relay system notices are unauthenticated. Undelivered envelopes stay queued until acknowledgement or retention expiry (at most 7 days). Resync can request history from your iPhone, without guaranteeing recovery of every expired sample. Apple Health write-back requires your allowed types and your iPhone's Health permissions.

FILES
Export JSON or CSV to Files or AirDrop, any time. Import a file to write its entries into Health.

HONEST ABOUT WHAT IT SENDS
Choose the types, see every sync in the Activity log, and remove the entries Syncky wrote. No account, no sign-in, no ads. Relay sees device IDs, IP address, time and message size, and none of your health values or data types. Usage statistics are off until you turn them on.

KEEPS ITSELF AWAKE
Background delivery from Health, Background App Refresh, a Shortcuts automation, Home and Lock Screen widgets, a Control Center control and an optional Live Activity with the sync status. The Reliability screen shows what woke the app in the last 24 hours and what to turn on when it did not.

OPEN PROTOCOL
The Syncky protocol, the reference agent and a reference server are being released under an open-source licence, so you can build your own receiver or agent.

Syncky Health is not a medical device and gives no medical advice.
