At Music Visualizer Pro, we prioritize user privacy. Because our rendering core is fully built in JavaScript and compiles videos on the client side, your audio tracks, video files, background images, and lyric details are never uploaded to our servers. All computing is executed locally in your browser memory.
We only collect minimal anonymous statistics, such as page views and license keys, to verify subscription status via Gumroad API integrations.
We use local storage keys to store user visualizer presets (e.g. particle size, rotation speed, and current visualizer style option), ensuring a convenient experience when reloading the app.
Our payment gateway is managed by Gumroad. Their data practices are covered under Gumroad's separate Privacy Policy.
