Privacy Policy

1. Technical Overview: Client-Side Audio Processing

OnlineMP3Editor operates as an entirely in-browser application using standard HTML5 APIs, specifically the Web Audio API, WebAssembly (WASM), and client-side JavaScript.

When you drag and drop or open an audio file (such as MP3, WAV, FLAC, M4A, or OGG) into OnlineMP3Editor:

• The file is read directly from your local filesystem into your browser's volatile system memory (RAM).
• All waveform rendering, cutting, trimming, multi-track mixing, and real-time DSP effects (such as equalizer, compressor, and volume envelopes) are computed locally by your CPU/GPU.
• When you export your audio, encoding into MP3 or other formats is executed directly in your browser. The finished file is downloaded directly to your local computer or phone.
• At no point during import, editing, playback, or export does your audio stream or transmit across the internet to any external server.

2. Information We Do NOT Collect

Because of our strict client-side design, we do NOT collect, inspect, store, or sell:

• Your audio recordings, musical compositions, voice clips, or sound files.
• Audio metadata, including ID3 tags, artist names, album titles, or timestamps.
• Personal identifiers such as your real name, email address, physical address, or phone number.
• Payment or billing details — OnlineMP3Editor is 100% free with no credit card requirements.
• Behavioral ad profiles or cross-site tracking fingerprints.

3. Local Browser Storage (Session Restore)

OnlineMP3Editor includes an optional session auto-restore feature. If you reload your browser or accidentally close the tab, the application saves project markers, track arrangement names, volume levels, and effect settings to your browser's private IndexedDB or localStorage on your own device.

This data is solely accessible by your browser on your device and is never synced to any remote server or cloud account. You can clear this storage at any time by clicking "Reset Project" or clearing your browser site data.

4. Third-Party Hosting & Server Logs

OnlineMP3Editor is served over secure, encrypted HTTPS as static files via global content delivery networks (such as Cloudflare or Vercel). When your web browser requests our HTML, CSS, JavaScript, and audio worker files, the hosting network may automatically log standard technical web server logs (e.g., your IP address, browser User-Agent header, and request timestamp) solely for:

• Defending against Distributed Denial of Service (DDoS) attacks and malicious abuse.
• Troubleshooting server uptime, performance, and cache hit rates.

These network logs never contain or correlate to your audio files or editing activity.

5. GDPR & CCPA / CPRA Compliance

Under the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA/CPRA), website visitors have the right to know what personal data is processed, request deletion, and opt out of data sales.

Because OnlineMP3Editor collects zero personal data, maintains zero user databases, and sells zero information to brokers or advertising networks, your privacy rights are safeguarded by default. You are never subject to automated profiling or algorithmic tracking.

6. Children's Privacy (COPPA)

OnlineMP3Editor is safe for all audiences, including educational classrooms and students. We do not knowingly solicit or collect information from children under the age of 13 in compliance with the Children's Online Privacy Protection Act (COPPA).

7. Changes to this Policy

We may periodically update this policy if new features or technical standards evolve. Any revisions will be reflected with an updated date at the top of this page.
