Privacy Policy for the Decibelion app for iOS

Mandy Software LLC of Colorado

Last updated: 2024-07-11

1. Introduction

This Privacy Policy explains the data collection practices of the Decibelion app developed by Mandy Software, LLC. By using the app, the End User (hereafter "User") accepts this policy and agrees to the data collection and processing described herein.

2. Microphone Data

2.1. Access to the Microphone

The Decibelion app requires the device microphone permission in order to use the audio-related features of the app.

2.2. Usage of Microphone Data

The audio data from the microphone never leaves the device, and it is never written to the phone's internal storage.

If enough people ask for a recording feature, a recording feature might be added in the future, but right now no audio data is saved.

Even if a recording feature is added in the future, the recorded data will still never leave the device without the User's explicit consent, such as via a "share" button that the User would use and then select where the User would like to share the data to.

2.3. Audio Data vs Usage Statistics

Microphone audio data is NOT a usage statistic and is NEVER sent to any server for processing or storage.

3. Anonymous Usage Statistics

Each time the User uses the app, certain anonymous usage statistics and other information is collected by Mandy Software. This is done for analytics purposes in order to improve the app.

While some of the app events' timestamp information may be used for identifying a particular app installation instance for better app analytics insight, none of the information can actually be linked to the person or the device from which this usage data originated.

For security purposes and to combat abuse, each time the data is collected, a hash of the User's current IP address is saved. However, the User's IP address itself is never retained.

3.1. Data Collected

The following information is collected every time the User uses the app.

Activity Name: Which screen of the app is opened (math mic, music mic, home page, etc.).
Decibelion App Version: The app version and package name.
First Launch Timestamp: A timestamp of when the Decibelion app was first launched after it was installed.
Current Timestamp: A timestamp in GMT of when the app is being used.
Device Type: Manufacturer and model; to know which devices to focus development and testing efforts on.
Locale: The region and language setting of the device; to gauge app language translation needs.
Operating System: Specifically, the iOS/iPadOS version; used for determining what new OS features can be integrated for most users.
Configuration: Device screen size and orientation to understand what screen configurations need to be optimized.
Battery Capacity: How quickly the app uses the battery to understand battery consumption and to optimize accordingly.
User Interaction: To improve app features based on popularity. Data includes but is not limited to:
- Usage count for each feature.
- Usage duration for each feature.
- Usage values if applicable: for example, the name of the clef that is selected on the "music mic" page.
App Performance: Basic information on the app's performance profile to understand the algorithm optimization needs.
Debug: Any unexpected conditions that might occur that require developer attention. This debug info is kept generic/anonymous.

3.2. Privacy

To maintain User anonymity, Mandy Software does not capture or associate any personal identifiers such as the device ID, user ID, advertisement ID, or IP address. Usage data is sent each time the app is either launched, closed, put into the background, or brought back into the foreground, but no personally-identifiable information (PII) is collected nor stored with this usage data.

4. Data Handling and Storage

This section describes how the data is stored and handled.

Data Storage: The usage data are stored on a server in the United States with backups of the data stored in Switzerland. The timestamps of the app use are still stored, but no device or user-specific information is retained. No personal data is stored.
Data Processing: The data is used for analytics purposes only, and it is processed in aggregate to reveal platform and usage patterns which allow for making informed decisions concerning the further development of the Decibelion app. App event timestamps such as the app first launch time may be used for semi-identifying an app installation instance in order to gain better insight into the usage patterns and aggregate user behavior, but these timestamps are useless for identifying the User herself or himself, and the timestamps are also useless for identifying the device itself, so the User and the device both remain anonymous.
Third-Party Processing: The data is never sent to any third parties and is always processed in-house by Mandy Software on its own servers in the United States.
Data Retention: The anonymous usage data are retained indefinitely.

5. Consent and User Rights

By using the Decibelion app, the User consents to the data collection and processing described in this privacy policy. There is no option to opt out of this data collection.

6. Changes to This Policy

Mandy Software may update this Privacy Policy periodically, so it is recommended that the User check this policy occasionally to stay informed about how Mandy Software is collecting and protecting the data generated from the use of the app.
