Viburrito
Privacy Policy
Effective October 20, 2026 · Muilyzz Corp.
Viburrito (the "app") is a vibrato practice app made by Muilyzz Corp. The app does not collect personal data, does not send it to us, and does not share it with anyone.
Microphone
The app listens through the microphone only while you practice. The sound is turned into pitch and vibrato measurements on your iPhone as you sing. It is never recorded, saved, or sent off your device. You can turn off microphone access at any time in the Settings app.
Practice history
The dates you practiced, your scores, and the measurements (speed, width, evenness, and pitch) stay on your iPhone. We cannot see them. Deleting the app deletes them. If you use iCloud Backup or back up your iPhone to a computer, they may be included in that backup like any other app data. Backups are managed by Apple and by you.
What the app does not have
No accounts, ads, analytics, tracking, or third-party code. The app does not connect to the internet.
Children
The app collects no personal data from anyone, including children.
Changes
If this policy changes, we will post the new version on this page with a new effective date.
