Privacy Policy for CPAP Tracker

Last updated: March 24, 2026

Overview

CPAP Tracker (“the App”) is designed to help users manage their CPAP equipment replacement schedules, track cleaning tasks, monitor sleep therapy progress, and maintain healthy CPAP usage habits. This privacy policy explains what data we collect, how we use it, and your choices regarding your information.

Data We Collect

Equipment & Cleaning Data

The App collects and stores the following data to provide its core functionality:

• CPAP consumable items (masks, tubing, filters, etc.) and replacement schedules
• On-hand inventory counts and reorder thresholds (when you opt in)
• Cleaning task completion records and notes
• Replacement history and dates
• Notification preferences for reminders

This data is stored locally on your device by default and is never transmitted to our servers.

Health Data

Apple HealthKit Integration:

• With your permission, the App reads sleep analysis data from Apple Health, including sleep duration, sleep stages, and time in bed
• The App may also read respiratory rate and oxygen saturation data if available
• This data is displayed within the App but is not stored separately — it remains in Apple Health
• The App does not write data to Apple Health

Manual AHI Tracking:

• You may manually log your Apnea-Hypopnea Index (AHI) values from your CPAP machine
• AHI entries include the date, AHI value, usage hours, and optional notes
• This data is stored locally on your device and optionally synced via iCloud (Pro feature)
• When iCloud sync is enabled, your health data is linked to your Apple ID but remains private to you — we cannot access it

Gamification Data

To encourage consistent equipment maintenance, the App tracks:

• Experience points (XP) earned from completing tasks
• Current and longest streaks for equipment replacement and AHI logging
• Achievements and badges unlocked

This data is stored locally and optionally synced via iCloud for Pro users.

Advertising Data

For users of the free version, the App displays advertisements through Google AdMob. AdMob may collect:

• Device identifiers (including Advertising Identifier if you grant permission)
• IP address and general location
• App usage and interaction data
• Ad performance metrics

You can opt out of personalized advertising through your iOS Settings (Privacy & Security > Tracking).

App Preferences

The App stores your preferences locally, including:

• Sleep goal settings
• Notification schedules and preferences
• Display preferences (including the celebration-animations toggle)
• iCloud sync settings

How Data Is Stored

Local Storage (Default)

All your data is stored locally on your device in a secure database within an App Group container. This data is protected by your device’s built-in security features, including encryption when your device is locked.

iCloud Sync (Optional, Pro Feature)

Pro subscribers can optionally enable iCloud sync to keep data synchronized across multiple devices. When enabled:

• Data is stored in your private iCloud account using Apple’s CloudKit service
• Synced data includes: consumables, cleaning records, replacement history, inventory counts, AHI entries, gamification progress, and achievements
• Data is encrypted in transit and at rest by Apple
• Only you can access your synced data — we cannot access your iCloud data
• You can disable sync at any time in the App’s Settings

Data Merge Behavior: When syncing across devices, the App intelligently merges your data to prevent loss. For example, it keeps your highest XP total and longest streaks from any device.

Widget Data Sharing

The App includes home screen and watch widgets that display your consumable status. Widgets access the same local database as the main App through a shared App Group container. No additional data is collected for the widget.

Third-Party Services

Google AdMob

The free version of the App displays advertisements provided by Google AdMob. Google’s privacy policy applies to data collected through ads: https://policies.google.com/privacy

SKAdNetwork Partners

The App includes SKAdNetwork identifiers for 49 advertising partners to enable privacy-preserving ad attribution on iOS 14 and later. This allows ad networks to measure campaign effectiveness without accessing your personal information. SKAdNetwork is Apple’s privacy-focused framework that does not share personally identifiable information with advertisers.

Apple Services

The App integrates with the following Apple services:

• HealthKit: To read sleep and respiratory data (with your permission)
• CloudKit: To sync data across your devices (Pro feature, optional)
• StoreKit: To process Pro purchases
• App Tracking Transparency: To request permission for personalized ads

Apple’s privacy policy applies to these services: https://www.apple.com/legal/privacy/

In-App Purchases

The App offers a Pro upgrade as a one-time, non-consumable purchase that unlocks additional features including unlimited consumables, iCloud sync, PDF export, low-stock reorder reminders, and an ad-free experience. All purchases are processed by Apple through the App Store. We do not collect or store your payment information. Your purchase history is managed by Apple and can be viewed in your App Store account settings.

Your Rights & Choices

Export Your Data

Pro subscribers can export a PDF report of their equipment and replacement history from the Settings screen.

Delete Your Data

You can delete all your data at any time using the “Reset All Data” option in Settings. This permanently removes all consumables, cleaning records, replacement history, inventory counts, AHI entries, and gamification progress from your device. If iCloud sync is enabled, you may also need to delete data from iCloud via your device’s iCloud settings.

Control iCloud Sync

You can enable or disable iCloud sync at any time in Settings. Disabling sync does not delete existing data — it simply stops syncing new changes. Your data remains on each device where it was previously synced.

Manage Permissions

You can revoke or modify the App’s permissions at any time:

• HealthKit: Settings > Health > Data Access & Devices > CPAP Tracker
• Notifications: Settings > CPAP Tracker > Notifications
• Tracking: Settings > Privacy & Security > Tracking

Disable Personalized Ads

You can opt out of personalized advertising by:

1. Going to iOS Settings > Privacy & Security > Tracking
2. Disabling “Allow Apps to Request to Track”
3. Or denying tracking permission when prompted by the App

You will still see ads, but they will not be personalized to your interests. Alternatively, upgrade to Pro for an ad-free experience.

Data Security

We take data security seriously:

• All data is stored locally on your device, protected by iOS security features
• iCloud data is encrypted by Apple in transit and at rest
• We do not operate servers that store your personal data
• We cannot access your local or iCloud data

Data Retention

• Local data is retained until you delete it or uninstall the App
• iCloud data is retained in your iCloud account until you delete it or disable sync
• Advertising data is retained according to Google’s data retention policies

Your Privacy Rights

For All Users

• Access: You can view all your data within the App at any time
• Deletion: Use “Reset All Data” in Settings to permanently delete all local data. For iCloud data, manage it through your device’s iCloud settings
• Portability: Pro users can export their data as a PDF report from Settings
• Opt-Out of Tracking: Deny ad tracking permission or disable it in iOS Settings > Privacy & Security > Tracking

If you are in the European Economic Area (EEA), you have additional rights under the General Data Protection Regulation:

• Right to Access: Request a copy of your personal data
• Right to Rectification: Correct inaccurate data via the App’s editing features

Legal Basis for Processing: We process your data based on your consent (HealthKit access, ad tracking) and legitimate interest (providing the App’s core functionality). You may withdraw consent at any time through iOS Settings.

For California Users (CCPA/CPRA)

If you are a California resident, you have the right to:

• Know what personal information is collected and how it is used
• Delete your personal information
• Opt-Out of Sale: We do not sell your personal information. Google AdMob may use device identifiers for advertising purposes, which you can opt out of by denying tracking permission

Children’s Privacy

CPAP Tracker is not intended for use by children under 13 years of age (or under 16 in the European Economic Area). We do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us so we can delete it.

International Users

Your data is stored locally on your device and, if you enable iCloud sync, in Apple’s data centers according to Apple’s data residency policies. Google AdMob may transfer advertising data internationally according to Google’s policies. For transfers outside the EEA, Google relies on Standard Contractual Clauses approved by the European Commission.

Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by updating the “Last Updated” date at the top of this policy. We encourage you to review this policy periodically for any changes.
