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. We use only privacy-friendly, cookieless analytics that collects no personal data.
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 use no cookies and store nothing on your device for tracking.
- We use Cloudflare Web Analytics — a privacy-friendly, cookieless service that measures aggregate visits and referrers. It does not use cookies, does not fingerprint your device, does not track you across other sites, and collects no personal data. Your audio is never sent anywhere.
- 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.
