Here is the complete, unabridged, and fully compliant Privacy Policy for your app, with every legal and Google Play policy requirement fully addressed.
Effective Date: July 29, 2026
Last Updated: July 29, 2026
This Privacy Policy describes how Bitrex Studio ("we," "us," or "our") collects, uses, stores, and protects your information when you download, install, and use the Lungs Test Health & Exercises mobile application (the "App").
By installing and using the App, you agree to the collection, processing, and use of your information in accordance with this Privacy Policy. If you do not agree with any part of this policy, please do not use the App.
Lungs Test Health & Exercises is intended strictly for general wellness, personal fitness tracking, and stress management purposes.
No Medical Diagnosis: The breath-hold timers, lung capacity tracking, and guided breathing exercises (e.g., Box Breathing, Pranayama) are not clinical diagnostic tools, medical devices, or treatments for any medical condition.
No Doctor-Patient Relationship: The content and calculations in this App do not constitute medical advice or substitute for professional diagnosis, medical examination, or treatment by a qualified healthcare professional.
Safety Warning: If you suffer from asthma, Chronic Obstructive Pulmonary Disease (COPD), cardiovascular conditions, epilepsy, high blood pressure, or are pregnant, consult a medical doctor before performing any breath-holding or deep breathing exercises. Stop using the app immediately if you experience dizziness, shortness of breath, faintness, or discomfort.
We prioritize user privacy and minimize data collection wherever possible.
A. Health, Fitness, and Usage Data
Data Collected: Breath-hold duration scores, exercise completion logs, personal streak counts, and custom timer preferences.
Storage Location: All health and fitness logs are stored locally on your device (using Android Local Storage / Shared Preferences).
Data Access: Bitrex Studio does not collect, upload, store, or sell your health metrics on external servers.
B. Automatically Collected Technical Data
When you use the App, automated logging software may gather technical data to ensure app performance and fix stability issues:
Device hardware model and manufacturer
Operating system version (Android OS)
IP address and country-level location
App performance telemetry (e.g., launch times, system crashes, freeze events)
Unique Advertising Identifier (Google Advertising ID)
The App requests the following Android runtime permissions to deliver its functionality:
Vibration (android.permission.VIBRATE): Required to provide tactile haptic feedback during guided breathing cycles (inhale, hold, exhale timing) so users can keep eyes closed.
Notifications (android.permission.POST_NOTIFICATIONS): Optional. Required only if you enable daily exercise reminders.
Internet Access (android.permission.INTERNET): Used strictly to fetch non-intrusive ads (if applicable) and transmit anonymous crash diagnostics to developer analytics services.
We do not access your camera, microphone, device contacts, precise GPS location, or external media files.
We may partner with trusted third-party services to monitor app performance, fix bugs, and support development through advertising. These third parties receive pseudonymized system data governed by their respective privacy policies:
Google Play Services: Used to facilitate app infrastructure, billing, and core Android APIs.
Google Analytics for Firebase / Crashlytics: Used to monitor anonymous app stability, crash reports, and system performance across different Android models.
Google AdMob (If applicable): Used to display non-intrusive advertisements. AdMob may process your Advertising ID to serve personalized or contextual ads.
We implement standard, industry-recognized security measures to protect your information:
All network transmissions made by the app use secure HTTPS/TLS transport security encryption.
Sensitive personal metrics are kept strictly within your isolated device sandbox and are not exposed over the network.
However, please be aware that no mobile device or transmission method over the internet can be guaranteed as 100% secure.
Local Data Deletion: You have full control over your stored exercise data. You can erase all test history and app records instantly by navigating to your phone's settings:
Settings > Apps > Lungs Test Health & Exercises > Storage > Clear Data
Alternatively, uninstalling the App will automatically purge all local logs from your device.
Account Deletion: The App does not require account creation, login credentials, or cloud synchronization. Therefore, we hold no user accounts on our servers.
Telemetry Removal Requests: If you wish to request the deletion of any technical telemetry or support emails sent to us, please contact us at bitrex.studio@gmail.com.
Our App is not directed to children under 13 years of age (or under 16 in the European Union). We do not knowingly collect or solicit personal information from children.
If you are a parent or legal guardian and discover that your child has provided personal information or that technical data was collected from a child without consent, please contact us immediately at bitrex.studio@gmail.com, and we will promptly erase such information from our records.
If technical logs or crash diagnostics are processed by third-party infrastructure (such as Google Firebase servers), that data may be transferred to and maintained on servers located outside of your state, country, or jurisdiction where data protection laws may differ. By using the App, you consent to these secure technical transfers.
Bitrex Studio reserves the right to modify or update this Privacy Policy at any time. Any changes will become effective immediately upon posting the updated Privacy Policy here with a revised "Last Updated" date. We encourage you to review this page periodically to stay informed about how we protect your information.
