SoberClock - Privacy Policy

 

Last updated: May 30, 2026

This Privacy Policy explains how Mel-Spectrum Analyzer ("we," "our") processes your data when you use our mobile application.

 

1. Processing of Physiological and Consumption Data

The SoberClock application provides a blood alcohol concentration (BAC) estimation tool based on recognized pharmacokinetic models.

·         Nature of the data: The application allows you to enter physiological parameters (biological sex, age, weight, height, and optional body measurements) as well as a log of consumed drinks.

·         Processing and storage: All entered data is processed and stored strictly locally on your device using Android's secure SharedPreferences.

·         Transmission and privacy: No personal, physiological, or drink-logging data is ever recorded, transmitted, or stored on external servers. The application requires no user account creation and operates completely offline.

2. In-App Purchases and Voluntary Donations

The SoberClock application is completely free of charge and guaranteed 100% ad-free.

To support ongoing development and maintenance, the application offers an optional voluntary donation system via the official Google Play Billing service.

·         Payment processing: All financial transactions are executed and secured directly by Google through the official Google Play infrastructure.

·         Financial data: We do not collect, process, or have access to any of your banking or credit card details.

·         Third-party policy: Transaction-related data is handled by Google in accordance with Google's own privacy policy.

3. Preference Data

We use local storage (SharedPreferences) to save your personal preferences (selected meal type, probatory license setting, display preferences) in order to maintain your configuration between sessions. This data is stored exclusively on your device and is never synchronized or shared externally.

4. Your Rights

You retain full control over your application data:

·         Data deletion: You can instantly reset or delete all your stored data at any time by clearing the drink history within the app or by uninstalling SoberClock from your device.

·         Permissions & Transparency: SoberClock requests no sensitive system permissions (no access to microphone, camera, contacts, or precise device location). We are committed to collecting zero personally identifiable information.
