Privacy Policy

Last updated: October 2026

Short version: your audio never leaves your device. The free audio visualizer at audiovisualizer.cc decodes files locally in your browser with the Web Audio API. We have no servers that receive, store, or process your audio — because there is nothing to send it to.

Audio files and links you load

Files you drop or choose stay on your device; the browser creates a temporary local object URL that is revoked when you load another track. Pasted audio links are fetched directly by your browser from the host you specify — we never proxy, cache, or log the contents. Closing the tab ends everything; nothing persists on our side.

Information we do not collect

No accounts, no sign-ups, no audio uploads, no listening history, and no audio fingerprinting. We do not ask for your name, do not track what you play, and do not build profiles of your music or voice recordings. If you email us via the Contact Us page, we receive only what you choose to send, and we use it solely to reply.

Cookies and local storage

The visualizer itself sets no tracking cookies and stores no audio in local storage. Your browser may retain ordinary technical data (such as cached static files) under its own policies. Volume or style preferences, if remembered at all, live only in your browser session.

Analytics and third parties

We do not embed advertising trackers, social pixels, or audio analytics SDKs in the visualizer. If we ever add privacy-respecting, aggregate-only measurement in the future, this policy will be updated first — and it will never include the contents of your audio.

Children's privacy

Because no personal data or audio is collected through the tool, there is nothing to knowingly collect from children either. Parents and teachers can use the visualizer in classrooms without creating accounts for students.

Your rights and contact

Since we hold no audio or accounts, there is generally nothing to access, correct, or delete. For any privacy question — including a message you sent us — write via Contact Us and we will respond within 2 business days.
