I highly value your privacy and transparency. This Privacy Policy explains how I, Koenraad Koster (“I”, “me”, or “my”), handle user and device data when you use any of my mobile applications published on official app stores (collectively referred to as the “Apps” or individually as the “App”).
1. Data I Collect
Depending on the specific functionality of the App you are using, the following (sensitive) user and device data may be processed:
A. Personal and Sensitive User Data
- Health and Fitness Data: If you use an App for health calculations or tracking (such as a BMI or BRI calculator), the App processes data that you manually enter, such as height, weight, gender, and age.
- Note: This data is used exclusively to calculate your respective scores and display them directly to you.
B. Device Data
- Device ID and Technical Specifications: Information about your operating system (e.g., Android version) and device model to ensure stability and compatibility.
- Diagnostic Data: Anonymous crash reports (collected via platform services like the Google Play Console) used solely to fix software bugs and improve performance.
2. How I Use Your Data
I use the collected data strictly for the following purposes:
- To provide and maintain the core functionality of the App (such as performing health analyses).
- To optimize the App’s performance and enhance user experience.
- To troubleshoot and resolve technical issues or crashes.
3. Data Storage and Security
- Local Processing: All health and personal data you input is processed and stored locally on your own device. I do not transmit this sensitive data to external servers.
- Security: I implement appropriate technical measures to protect your data from loss, misuse, or unauthorized access within the local environment of your device.
4. Third-Party Data Sharing
I do not sell, trade, or share your personal or sensitive device data with third parties.
Only anonymized or aggregated diagnostic data may be shared with app stores (such as Google) via automated crash reporting, in accordance with the respective platform’s privacy policy.
5. Your Rights
Since your data is stored locally on your device, you retain full control:
- You can modify or delete your data at any time within the App’s settings.
- Uninstalling the App will permanently delete all locally stored data.
6. Changes to This Privacy Policy
I may update this Privacy Policy from time to time to reflect changes in my development practices or for legal reasons. The revised version will be effective immediately upon posting.
