Privacy Policy

Last updated: January 10, 2026

1. Introduction

ChunkAudio ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our audio splitting tool at chunkaudio.com (the "Service").

We built ChunkAudio with privacy as a core principle. Unlike most online audio tools that upload your files to remote servers, ChunkAudio processes everything directly in your web browser using client-side JavaScript and the Web Audio API.

2. Information We Do NOT Collect

We want to be clear about what we do NOT collect:

• Audio Files: Your audio files are never uploaded to our servers. All processing happens locally on your device.
• Personal Information: We don't require registration, email addresses, names, or any personal information to use ChunkAudio.
• Payment Information: We don't process payments directly. If you choose to support us, any payments are handled by third-party processors (like Stripe or PayPal) and we never see your full payment details.
• File Metadata: We don't collect or store information about your audio files, including filenames, durations, or content.

3. Information We May Collect

To improve our service and understand how people use ChunkAudio, we may collect limited, anonymous data:

• Usage Statistics: Anonymous counts of how many times the audio splitter is used (not tied to individual users).
• Technical Information: Browser type, device type, and general geographic region (country-level) for analytics purposes.
• Error Reports: Anonymous error logs to help us fix bugs and improve the service.

4. How Your Audio Is Processed

ChunkAudio uses modern web technologies to process audio entirely in your browser:

• When you upload a file, it's loaded into your browser's memory using the File API.
• The Web Audio API decodes and processes the audio locally on your device.
• Split audio chunks are created in your browser's memory.
• When you download, files are saved directly from your browser to your device.
• Once you close the browser tab, all audio data is cleared from memory.

At no point during this process is your audio transmitted over the internet or stored on any server.

5. Cookies and Local Storage

We use minimal cookies and local storage:

• Preference Cookies: To remember your settings (like chunk duration preferences).
• Analytics Cookies: Third-party analytics (like Google Analytics) may use cookies to help us understand aggregate usage patterns.
• Advertising Cookies: If ads are displayed, ad networks may use cookies as described in their privacy policies.

You can disable cookies in your browser settings, though some features may not work as expected.

6. Third-Party Services

We may use the following third-party services:

• Google AdSense: For displaying advertisements. Google's use of cookies is governed by their Privacy Policy.
• Analytics Services: To understand how our service is used in aggregate.
• CDN Services: To deliver JavaScript libraries faster (like JSZip for ZIP file creation).

7. Data Security

Because your audio files never leave your device, they are protected by your own device's security. Our website is served over HTTPS to ensure secure communication. We implement security headers and best practices to protect against common web vulnerabilities.

8. Children's Privacy

ChunkAudio is not directed at children under 13. We do not knowingly collect any personal information from children. If you believe a child has provided us with personal information, please contact us.

9. Your Rights

Depending on your location, you may have certain rights regarding your data:

• Right to know what data we collect (this policy explains that)
• Right to delete your data (since we don't store personal data, there's nothing to delete)
• Right to opt-out of analytics cookies (use your browser settings)

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify users of any material changes by posting the new policy on this page with an updated "Last updated" date.
