Privacy Policy

Welcome to Pain Tracking. We understand that your health information is deeply personal and sensitive. This privacy policy explains how our app handles your data and what measures we take to protect your privacy.

This app was designed specifically for cancer patients undergoing chemotherapy treatment to track their pain levels, side effects, and symptoms. We believe that health data should remain under your complete control.

We do NOT collect or transmit:

• Personal identification information (name, email, phone number)
• Location data
• Your health data — pain entries, symptoms, medications, notes — these stay on your device only
• Usage analytics or behavior statistics
• Firebase or Google Analytics data

Google AdMob may collect (for ad serving only):

• Device advertising identifier (Android Ad ID)
• IP address (for general location/ad targeting)
• Ad interaction data (impressions, clicks)
• Device information (model, OS version, language)

All health information you enter in Pain Tracking is stored locally on your device:

• Pain entries and intensity levels
• Side effects and symptoms
• Chemotherapy round information
• Medication records
• Daily check-ins and notes

This data is stored using a secure local database on your Android device and is only accessible by the app. No external servers are involved in storing your health information.

Pain Tracking is free to use and is supported by ads delivered through Google AdMob. Ads are displayed in the Dashboard and Add Entry screens and are clearly labeled.

How AdMob works

• Ads require an active internet connection to load. If you are offline, no ads will appear.
• AdMob may personalize ads based on your general interests and device information.
• You can opt out of personalized ads on your Android device: Settings → Google → Ads → Delete advertising ID or enable "Opt out of Ads Personalization".
• AdMob's data practices are governed by Google's Privacy Policy.

The app itself does not access, read, or transmit any AdMob data. Ad delivery is handled entirely by the Google Mobile Ads SDK operating independently of the app's health data.

The app provides options to export and share your data:

Export to JSON

You can export all your data as a JSON file to your device storage. This backup file is saved to a location you choose and remains under your control.

Share to cloud services

You can share your backup file using Android's share feature to any service you prefer (Google Drive, email, etc.). The app does not connect to any cloud service directly – you always control where your data goes.

All core features of Pain Tracking work completely offline. No internet connection is required to log entries, view history, or manage your data. This means:

• No health data is transmitted over the internet during normal use
• You can use all health tracking features anywhere, anytime, without connectivity
• Your health information stays secure on your device
• An internet connection is only used by Google AdMob to load and display ads. If you are offline, ads simply will not appear — no functionality is affected.

We do not include any proprietary tracking or analytics in our app. Specifically, we do not use:

• Google Analytics or Firebase Analytics
• Crash reporting services that collect personal user data
• Behavior tracking or usage pattern collection by us
• Any sharing of your health data with third parties

Note: Google AdMob (our ad partner) operates its own ad-serving processes as described in the Advertising section above. This is limited to ad delivery and does not involve your health data in any way.

Pain Tracking integrates with the following third-party services:

• Google AdMob: Provides in-app advertising. AdMob may collect standard ad identifiers and interaction data. Your health data is never shared. See Google's Privacy Policy.
• Android System Share: When you choose to share your backup, Android's built-in share feature is used. The app does not control what happens to your data after you share it with another app.
• Storage Access Framework: Used when you export backups to allow you to choose where to save files on your device.

We take the following measures to keep your data secure:

• Health data is stored in the app's private storage area, inaccessible to other apps
• No network permissions are required for core health-tracking functionality
• Exported files are saved to locations you control
• The app follows Android security best practices

Please note that you are responsible for securing your device (screen lock, encryption, etc.) to protect all apps and their data.

Since all health data is stored locally on your device, you have complete control:

• Access: View all your data anytime within the app
• Export: Export all your data as a JSON file or PDF report
• Delete: Delete individual entries or all data from the Settings screen, or by uninstalling the app
• Portability: Your exported data can be imported back into the app
• Ad opt-out: You can reset or delete your Android Advertising ID in your device settings to limit ad personalization

Pain Tracking is intended for adults managing their cancer treatment. The app is not directed at children under 13. We recommend that children use the app under adult supervision. AdMob is configured for general audiences.

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.

If you have any questions about this privacy policy or the app's privacy practices, please contact us through the Google Play Store listing or by leaving a review with your question.
