Hvylya is an independent project by Oleksandr Kazantsev, building audio software for Windows and the devices around it. You can reach us at oleksandr@hvylya.com.
We don't use advertising cookies, tracking pixels or third-party analytics on this site.
The “Try the meter” demo runs entirely in your browser. Audio from your microphone is never recorded, stored or sent to us.
Only to tell you when the beta and the first release are available, and to understand which setups to test first. We don't sell or share your email with anyone else. The legal basis is your consent, which you can withdraw at any time.
Until you ask us to delete it, or until the beta programme ends — whichever comes first.
Under the GDPR you can ask to access, correct or delete your data, or object to its use. Email oleksandr@hvylya.com and we'll act on it promptly. You can also complain to the data protection authority in your country.
The phone app needs microphone permission to capture your voice and sends audio to your computer over the connection you choose (Wi-Fi, USB or Bluetooth). A separate privacy policy for the app will be published with the first release.
