Privacy Policy
Last updated: 4 July 2026
The short version: your audio never leaves your device. This tool runs entirely in your browser. We don't have a processing server, we don't require accounts, and we don't use cookies or analytics.
Your audio files
- Audio files you select are processed locally in your browser using your device's own processing power (the Web Audio API).
- Your audio is never uploaded to our server or any third party. There is no upload — the site has no server-side audio processing at all.
- Exported MP3, WAV, and video files are generated on your device and saved directly by your browser. We never see them.
Accounts, cookies, and analytics
- No account or signup is required or offered.
- We currently use no cookies and no analytics or tracking scripts.
- If this ever changes, this page will be updated first.
Local storage
The site stores one small preference in your browser's localStorage: your chosen background visual style. It never leaves your browser, and you can clear it anytime via your browser's site-data settings.
Preset links
The "Copy preset link" feature puts your slider settings (numbers like speed and reverb values) into a URL you can share. That URL contains only those effect settings — never your audio, filenames, or anything about your device. Sharing such a link is entirely your choice.
Self-hosted assets
All fonts and code libraries are hosted with the site itself. Loading this site makes no requests to third-party servers (no Google Fonts, no CDNs).
Hosting logs
Like any website, the static hosting provider that serves these files may record basic server logs — typically your IP address, browser type, and timestamp of the page load. This is standard web infrastructure outside our control; no audio or usage data is part of it.
