Privacy Policy

Last updated: June 2026

We respect your privacy and are committed to protecting it. Because of how M4BConvert is built, we collect absolutely minimal information about you. This policy explains what data we do collect, how we use it, and how your files are handled when you use the service.

1. Your files and audio data

Short version: we never see them. All file processing happens entirely inside your web browser, on your own device. Your audio files are never uploaded to our servers.

M4BConvert is a client-side application. Converting, splitting, merging, and packaging audio files all happen locally using your device's own processor and memory. This means:

  • No uploads. Your audio files are never sent to our servers.
  • No storage. We do not host, store, or have any access to the contents of the files you process.
  • Automatic cleanup. Any temporary files written to your browser's sandboxed local storage during conversion are discarded automatically when the job completes or you close the tab.

Because your data never leaves your device, it is impossible for us to view, share, or leak your audio files.

2. Information we collect

While we do not collect your audio files, we do collect basic, non-personally identifiable information required to keep the website running securely and to understand how it is used.

A. Infrastructure and security (Cloudflare)

We use Cloudflare to secure and accelerate the website. Cloudflare automatically logs standard technical information to prevent DDoS attacks and block malicious traffic. This includes:

  • Your IP address (used strictly for security and abuse prevention)
  • Browser type and version
  • Operating system
  • Date and time of your visit

This data is processed by Cloudflare under their own Privacy Policy.

B. Analytics (Google Analytics)

We use Google Analytics to understand our website traffic. This helps us see how many people use the tool and which features are most popular. The data collected is aggregated and does not personally identify you. You can learn more about how Google uses this data at Google's Privacy & Terms.

3. Cookies and advertising

Engine caching

Your browser may cache the conversion engine files locally to speed up repeat visits, using standard browser caching mechanisms. This is handled automatically by your browser and does not involve any cookies or tracking.

Advertising (Google AdSense)

We use Google AdSense to display advertisements that help keep this tool free. Google AdSense may use cookies or similar technologies to serve ads based on your prior visits to this website or other websites. You can opt out of personalised advertising by visiting Google Ads Settings.

4. How we use your information

The minimal technical and analytical data we collect is used solely to:

  • Maintain and secure the website via Cloudflare.
  • Monitor performance and fix technical issues.
  • Understand general usage trends to improve the tool.
  • Serve advertisements through Google AdSense to support the hosting of the site.

We do not use any collected data to build personal profiles, make automated decisions about you, or sell your information to third parties.

5. Sharing your information

We do not sell, rent, or trade your personal information. We share data only with the trusted third-party service providers named in this policy — Cloudflare for security, Google for analytics and advertising — strictly for the purpose of operating and supporting the website. These providers are bound by their own privacy policies.

We may also disclose information if required to do so by law or in response to a valid legal request.

6. Children's privacy

M4BConvert is a general-audience utility and is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will take steps to delete it.

7. Changes to this policy

We may update this Privacy Policy from time to time. If we make significant changes, we will update the "Last updated" date at the top of this page. Your continued use of the service after changes are posted constitutes your acceptance of the updated policy.

We recommend checking this page periodically if you use the service regularly.
