Blood Pressure Tracker: Cardio

Effective Date: June 16, 2026

At Blood Pressure Tracker: Cardio (developed by KAAF DEVS, accessible via our app packages under com.kd.bptracker), we respect and protect the privacy of our users. This Privacy Policy documents how we handle, persist, and process information when you utilize our mobile health tracking application.

1. Local Data Storage & Absolute Sovereignty

Health Data Sovereignty

We believe your medical health telemetry belongs purely to you.

  • All blood pressure recordings, systolic and diastolic values, heart rate/pulse (BPM) records, calendar timestamps, temporal notes, medication status indicators, and personalized profiles are stored strictly and rawly on your physical Android device.
  • We use a high-performance local SQLite Room database engine.
  • There are no external servers, no cloud storage synchronized by us, and no central data repositories.

User-Initiated PDF Reports

If you choose to export your log as a PDF report, this file is compiled locally on your device. It is only shared with third parties (such as your physician, family member, or healthcare professional) when you explicitly initiate a share or export action utilizing standard Android share sheets or storage access choices.

2. Integrated Services & Third-Party SDKs

To maintain free access to our analytical tracking utilities, our application utilizes third-party advertising services which may collect identifiers to serve contextual or personalized advertisements.

Google AdMob (Google Mobile Ads SDK)

Our application integrates AdMob to display banner advertisements at the bottom of our layout and interstitial ads during premium reports downloads. These tools may collect and analyze certain technical, non-sensitive parameters:

  • Device and Advertising Identifiers: Google's AdMob SDK may collect your Android Advertising ID (AAID) for personalization, frequency capping, attribution, and reporting.
  • Diagnostics & Telemetry: Standard Crash logs, app latency metrics, and network configurations required to serve ads securely.

To understand how Google uses, targets, and protects this information, please consult the official policy guidelines:

3. Storage and Network Permissions Required

To fulfill core functional expectations, our application declares and operates with minimal standard Android permission structures:

  1. Network State & Internet (android.permission.INTERNET): Required strictly for Google Mobile Ads/AdMob SDK to retrieve ad creatives and check active connectivity states.
  2. Notification Alerts (android.permission.POST_NOTIFICATIONS): If granted voluntarily, this allows our application to issue local alarms and tracking reminders. It is processed completely offline.

4. Children's Online Privacy Protection

Given the medical and health-tracking focus of our tools, our target audience is exclusively directed at users aged 18 and older. We do not knowingly collect personal or health-identifying information of children under 13. If a parent observes that temporary configurations or logs have been established by a minor, please contact us immediately to purge the local records if desired.

5. Security & Deletion

Since KAAF DEVS maintains zero servers and cannot access your local tracker data, you have total control over data purging:

  • You may wipe individual rows directly from the records log UI.
  • You can clear all compiled databases instantly by entering your Android device settings and clicking "Clear Storage / Clear Data" for the Blood Pressure Tracker application.
  • Uninstalling the application automatically deletes all local databases.

6. Contact and Administration

If you have questions, feedback, or compliance concerns regarding this Privacy Policy, feel free to contact us:
