What we collect

The generator runs entirely in your browser — your settings and sessions never leave your device. We use privacy-friendly, cookieless analytics to count visits in aggregate.

If you choose to download an MP3, we ask for your email so we can send your downloads and the occasional binaural-beats tip. That's the only personal data we store, and only if you opt in.

Your email

• We never sell or share your email.
• Every email includes a one-click unsubscribe.
• You can ask us to delete your data at any time.

About this tool

isochronic.info exists because most isochronic tones sites overpromise. We grade every claim by the strength of the actual research — and we tell you plainly when the evidence is weak, mixed, or absent. The generator is free, runs entirely in your browser, and always will be.
