Privacy Policy
Last updated: July 15, 2026. Learn how our browser-local compilation architecture keeps your media 100% private.
No Server Uploads
Files stay on your local disk. We have no backends or upload channels.
No Data Collection
We do not collect audio streams, file names, or metadata.
No Registration
No accounts or credit card profiles are required or created.
1. Overview
At M4AtoWAV.com, your privacy is our highest priority. We have engineered this platform so that it operates entirely client-side. Unlike conventional media tools that upload file streams to third-party cloud servers for processing, all operations on this site are completed in your local web browser.
2. Processing Architecture
When you load a file onto M4AtoWAV.com:
- Our website downloads a standard WebAssembly (Wasm) compiler framework.
- This Wasm code is run inside your browser's local sandbox runtime environment.
- Your device reads the M4A binary arrays, converts them into WAV PCM format, and stores the resulting WAV container locally in your browser memory.
- The browser then triggers a local save-to-disk operation.
No files, parts of files, or derived media clips are transmitted over the network.
3. Information We Collect
We do not collect any personally identifiable details, audio file streams, filenames, metadata headers, or conversion logs.
Web Hosting Logs: Standard web hosting platforms (like Cloudflare, Vercel, or GitHub Pages) might log basic network requests (like your IP address, browser type, and timestamps) to serve the static assets (HTML, CSS, JS) to your device. These logs are used only for network security and traffic optimization.
4. Analytics & Advertising
To keep the user experience premium, clean, and fast:
- We do not track you with invasive cookie frameworks.
- We do not share your profiles or actions with marketing agencies.
- We do not sell user data.
5. Updates to This Policy
We may update this Privacy Policy from time to time to match changing browser technologies. However, the fundamental core of this website—that files are compiled 100% locally and never uploaded—will remain unchanged.
