Privacy Policy

Introduction

Welcome to our Privacy Policy. This document explains how we protect your privacy when you use our free online audio conversion service.

Important Commitment: Our service uses WebAssembly technology to process audio files locally in your browser. Your audio files are never uploaded to our servers.

Information We Collect

We collect very limited information:

• Technical Information: Basic website usage statistics, such as pages visited and conversion counts (without file content)
• Device Information: Browser type, operating system type (used to optimize conversion performance)
• Contact Information: Email address only when you actively contact us

Information We Do NOT Collect:

• Your audio file content or filenames
• Personal identification information (unless you voluntarily provide it)
• Account information (we don't require registration)

How We Use Your Information

We use the limited information we collect for the following purposes:

• To provide and improve our audio conversion service
• To optimize conversion performance for different devices and browsers
• To respond to your technical support requests
• To analyze service usage to improve user experience

Audio File Processing

Local Processing Commitment:

• All audio conversions are completed locally in your browser
• Your audio files never leave your device
• We cannot access, view, or store your audio files
• After conversion, files are only stored on your device

Data Security

Because we use local processing technology:

• Your audio files remain under your complete control
• No file transmission risks
• No server storage risks
• Your privacy is maximally protected

For the limited technical information we collect, we implement appropriate security measures to prevent unauthorized access.

Third-Party Services

We may use the following third-party services:

• Website analytics services (collecting only anonymous usage statistics)
• CDN services (for loading WebAssembly components)

These services do not access your audio files or personal information.
