Privacy Policy

1. Overview & Privacy-First Architecture

At MP3zuMP4 (https://www.mp3zump4converter.com), we respect your personal privacy. We engineered our audio-to-video conversion platform to operate entirely in your browser using modern WebAssembly and HTML5 technologies.

This Privacy Policy explains what technical information we process, how we protect your rights under applicable data protection laws (such as GDPR and CCPA), and our strict commitment to zero media retention.

2. Media Files & Zero Retention Guarantee

When you convert an MP3 audio track into an MP4 video, all processing happens locally on your device:

• No Media Uploads: Your MP3 files, background images, album artwork, and output videos are never uploaded to or stored on our servers.
• Temporary In-Memory Processing: Media data exists only in your local browser memory during the active conversion session and is erased when you close or refresh the tab.
• No Content Inspection: We do not inspect, retain, analyze, or claim ownership of any files you process.

3. Technical Information We Collect

We do not require user account registration, passwords, or personal profiles to use our converter. However, like most standard web services, our web hosting infrastructure automatically logs basic technical information for security and performance purposes:

• IP address and approximate geographic location (country/city level).
• Browser type, version, operating system, and language preferences.
• Referring URLs, requested pages, and access timestamps.

This data is used solely to maintain server stability, prevent DDoS attacks, and diagnose operational issues. It is not linked to any personal identities.

4. Cookies, Local Storage & Advertising Disclosures

We use browser storage technologies to provide essential functionality:

• Essential Local Storage: We use mp3zump4_cookie_consent to record whether you acknowledged our cookie banner so it is not shown repeatedly.
• Cookies Policy: For a full breakdown of storage keys and controls, please view our dedicated Cookies Policy.

Google AdSense & Third-Party Cookies

We may display advertisements served by Google AdSense and its certified advertising partners to keep our converter completely free:

• Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites on the internet.
• Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to our site and/or other sites on the internet.
• Users may opt out of personalized advertising by visiting Google Ads Settings or through aboutads.info.

5. Your Privacy Rights (GDPR & CCPA/CPRA)

Depending on your location, you may have rights under regional data protection laws:

• Right to Access: Request details on any technical log data associated with your interactions.
• Right to Erasure: Request the deletion of any server communication records.
• Right to Object & Opt-Out: Restrict analytics or advertising tracking via your browser privacy settings.
• Non-Discrimination: Equal access and identical functionality across all our tools regardless of your privacy choices.

6. External Links
