Introduction

Accelerando ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how our mobile application handles information when you use our music player app that adjusts playback speed based on your movement.

Information We Collect

Location Data

Accelerando collects precise location data (GPS coordinates and movement speed) to provide the core functionality of the app - adjusting music playback speed in real-time based on your movement pace.

Audio Files

The app accesses audio files that you explicitly select from your device to play music. We only access files you choose to add to the app.

Usage Data

The app stores locally:

• Your playlist configuration
• Preferred speed settings (running, cycling, driving presets)
• Last played track information

How We Use Your Information

Your location data is used exclusively for:

• Calculating your current movement speed (running, cycling, or driving)
• Adjusting music playback speed in real-time to match your pace
• Providing the core functionality of the app

Your audio files are used exclusively for:

• Playing music through the app's audio player
• Applying speed adjustments to playback

Data Storage and Processing

All data processing happens locally on your device.

• Location data is processed in real-time and is not stored on your device or transmitted anywhere
• Audio files remain on your device; we do not upload, copy, or transmit them
• Playlist and preferences are stored locally on your device only
• We do not have servers that collect or store your data

Your Rights and Choices

You have full control over your data:

• Audio Files: You control which files the app can access through system File picker. You can remove files from playlists at any time.
• Data Deletion: All app data is stored locally on your device. Deleting the app will permanently remove all associated data.

Background Location Usage

Accelerando uses location data in the background to continue adjusting music speed while you exercise with the app running in the background. This is essential for the app's core functionality during workouts.
