Key Changer Privacy Notice
The music you choose is decoded, adjusted and exported in your own browser. We do not request or store your source MP3 file on the Superbackings server.
To provide free downloads, we use an existing Superbackings account or ask you to create one. We process your account name, username, email address, password and daily download count in order to provide this service. Daily counts use UTC dates.
Account creation uses Cloudflare Turnstile to reduce automated registrations; Cloudflare processes data needed to provide that verification. Turnstile is only required to create a new account.
Marketing messages are optional and require a separate unchecked opt-in checkbox. You may unsubscribe from promotional messages at any time using the link provided in any marketing email or contacting Superbackings through its website.
Technical note: the app currently requests its pitch-shifting engine and MP3 encoder from a third-party content delivery network; these providers may receive ordinary connection data such as IP addresses. Your selected MP3 is not sent to those services.
