The details
- 01Install it on any number of PCs you use yourself. Sharing it among several people is outside the licence.
- 02The licence cannot be transferred or resold.
- 03There are no licence keys. The app makes no connection of any kind to check whether you are entitled to run it, and it never creates an account.
- 04Updates stay available at the same address.
This app is not a medical device. What people hear and feel varies from person to person.

6 QUESTIONS
Questions people ask
Why is the web version free and the app not?
The web version does as much as a browser allows — it applies to the audio in that tab. The desktop edition works outside that boundary. We will not lock the web version later.
Is there a trial?
We did not build one. The web version does that job instead, with no time limit and no features held back. Hear whether the sound suits you, then decide.
Does it run on a Mac?
Not yet. There is only a Windows edition today. On a Mac, use the web version.
What do I get when I pay?
You land on the download page immediately. Double-click the file and it runs — there is no installer. Paddle emails the receipt.
How do refunds work?
Write to [email protected] with your order number within 14 days of payment and you get the full amount back. We do not ask why. Refund policy
Where does my music go?
Nowhere. Everything happens on your device, and there is no path by which your music could reach a server. Privacy policy
