Privacy Policy

1. Overview

Blood Oxygen Monitor (“the App”) is an iPhone and Apple Watch companion for monitoring blood oxygen (SpO₂) readings from Apple Health / HealthKit and delivering optional alerts. This policy explains what information the App handles and how.

Important: The App is for personal wellness monitoring only. It is not a medical device, is not intended for diagnosis or treatment, and is not a substitute for professional medical advice. Seek emergency care for critical symptoms.

2. Data We Process

• Health data (SpO₂ and related HealthKit samples): Read from Apple Health with your permission. Used on-device for monitoring, alerts, trends, night reports, widgets, and optional export that you initiate.
• App settings: Alert thresholds, alarm preferences, theme preferences, and similar configuration stored locally on your devices.
• Membership / purchase status: Subscription or entitlement state needed to unlock Premium features. Purchases are processed by Apple; we do not receive your full payment card details.
• Optional environmental context: If enabled by the App’s features (for example altitude / pressure caches for charts), related values may be stored locally with readings.

3. Where Data Is Stored

• Health and monitoring data are stored locally on your devices (and in Apple Health where applicable).
• Shared data between iPhone, Apple Watch, and widgets uses Apple’s App Group / system frameworks on your devices.
• We do not operate a backend that uploads your health readings to our servers. The App is designed for on-device processing.
• Optional iCloud backup: If you choose Backup Now, the App encrypts alert times and the thresholds set at those times on your device, then stores the encrypted file in your iCloud account. It does not include blood oxygen values. You may also choose to include altitude and pressure history in an encrypted backup. You create one password for both; the App does not store it and cannot recover the backups if you lose it. Restoring alerts requires renewed Apple Health access, and records without matching readings cannot be reconstructed. Earlier unencrypted backups are replaced after a successful encrypted backup or restore, or can be deleted by you.

4. Sharing

• We do not sell your health data.
• Purchases and subscription management are handled by Apple under Apple’s terms and privacy practices.
• If you use export/share features, you choose where the file goes (for example Mail, Files, or another app you select).

5. Premium Features & Purchases

Monitoring and alerts remain available under the free experience described in the App. Widgets and certain analysis features may require a Premium subscription or entitlement. Billing, refunds, and family Ask to Buy approvals are managed through Apple / App Store.

Terms of Use (Apple Standard EULA): Apple Licensed Application End User License Agreement

6. Your Choices

• Revoke HealthKit access in iOS Settings → Privacy & Security → Health.
• Delete locally stored App data by removing the App (and related Watch app) or using in-app deletion options where provided.
• Manage or cancel subscriptions in your Apple ID subscription settings.

7. Children

The App is not directed to children under 13 (or the minimum age required in your region). Do not use the App to collect health data from children where prohibited.

8. Changes

We may update this policy as the App evolves. The “Last updated” date at the top will change when we do. Continued use after an update means you accept the revised policy.
