Privacy Policy

Effective: March 2026

Overview

WeaveHub Technologies LLC ("WeaveHub", "WeaveHub Technologies", "we", "our") builds local-first integrations. HealthSync reads Apple HealthKit data on your device and can write selected metrics to a Google Sheet you choose. We do not operate a cloud service for your health data and do not store, use, share, or retain Google user data on WeaveHub servers.

Data Accessed

  • Google Sheets data: Spreadsheet metadata (such as file name and ID) and the specific sheet contents needed to write metrics to the sheet you select.
  • HealthKit data: The metrics you explicitly authorize (e.g., heart rate, sleep, activity).

Data Usage

  • Google Sheets access is used solely to write your selected HealthSync metrics into your chosen sheet.
  • HealthKit data is processed on-device and then sent to your destinations (Google Sheets and/or Home Assistant) that you configure.

Data Sharing

  • We do not share Google user data with third parties.
  • Data is sent only to the services you connect (your Google Sheet and/or your Home Assistant instance).

Data Storage & Protection

  • WeaveHub Technologies LLC does not store Google user data or HealthKit data on our servers.
  • Google access is granted via OAuth and communications with Google APIs occur over HTTPS.
  • If you configure a Home Assistant webhook, data is posted to your webhook URL; protect webhook IDs like secrets.

Data Retention & Deletion

  • WeaveHub Technologies LLC retains no Google user data.
  • To stop access, revoke HealthSync's Google account access in your Google account settings.
  • To delete data written to Google Sheets, remove rows or delete the sheet in your Google account.

Permissions

  • HealthKit read access is requested only for metrics you select.
  • Google Sheets access is requested only to write to the sheet you choose.
