Sanguio — Privacy Policy
Last updated: May 2026
Summary
Sanguio (previously published on the App Store as BioTrack+) collects no personal data. Anything you record stays on your device and in your private iCloud. We don't run servers, we don't use analytics, and we don't share data with third parties.
What data is stored?
The app lets you log blood marker readings (glucose, uric acid, ketones, and more). That data is stored locally on your iPhone, iPad, or Apple Watch — and, if you enable iCloud sync, replicated to your private iCloud via CloudKit. Only you have access to it.
Data collection
- We don't require an account.
- We don't collect unique identifiers, IDFA, emails, names, or location.
- We don't use analytics, telemetry, or tracking tools.
- We don't show ads.
iCloud and CloudKit
When iCloud sync is enabled, your data is replicated across your Apple devices through Apple's CloudKit infrastructure, under your personal iCloud account. Seasby has no access — technically or legally — to that data.
AI Analysis
Trend and pattern analysis runs on-device. Your data never leaves your device for that processing.
Deleting your data
You can delete all your data by removing the app from your devices and deleting the Sanguio data from Settings → iCloud → Manage Storage.
