Open Health Bridge is a local-first Android health data bridge for Health Connect + manual logs.

This repository now contains a runnable developer-preview foundation aligned with the April 2026 v2.0 spec:

• Multi-module Android structure (app, core/*, data/*, feature/*, integration/*)
• Core domain model + HealthBridgeService boundary
• Nutrition, Wellness (Heart Rate, Sleep, Recovery) & Cycle Tracking (Fertility, Menstruation, Sexual Activity)
• Health Connect Integration with permission rationale and data visibility (Android 11+ support)
• Live Test Dashboard in-app for verifying Health Connect data access
• Room table definitions for MVP entities
• WorkManager sync constraints for charger + idle behavior
• Local loopback API server (127.0.0.1) with /v1/health, /v1/snapshot, /v1/summary, /v1/workouts, /v1/nutrition, /v1/recovery, /v1/prs
• Encrypted OpenHealthConnect snapshot bundle export for Syncthing, Nextcloud/WebDAV, or Tailscale-oriented transports
• Direct Pairing mode for pushing encrypted snapshot bundles straight to OpenHealthConnect via HTTP (no shared folder required)
• Nextcloud/WebDAV is supported as a first-class folder-sync path alongside Syncthing
• Schema and setup docs

./gradlew :app:assembleDebug

Requirements: Android SDK installed locally (ANDROID_HOME or local.properties with sdk.dir).

Some PR tools reject binary files. This repo therefore excludes gradle/wrapper/gradle-wrapper.jar. If missing after clone, regenerate with:

gradle wrapper --gradle-version 8.14.3

• No cloud sync
• No analytics SDKs
• Pairing key stays on-device in encrypted storage
