Privacy Notice

We keep this short because we collect very little.

• Pitch detection runs on your device. Live pitch training uses your microphone, and that audio is processed in your browser. We don’t receive, store, or transmit your microphone audio.
• Optional stem-separation feature. If you use the karaoke / stem feature, the audio file you provide is handled only to produce the result you asked for, and only for as long as needed to deliver it. We don’t use it to train models, and we don’t sell it or share it with third parties for their own use. You’re responsible for having the rights to any audio you provide (see our Terms).
• Community features. If you share melodies or scales, appear on the leaderboard, or join jam sessions, we handle the information you choose to provide (such as a display name and scores) to operate those features.
• Newsletter (optional). If you sign up, we use your email only to send the updates you asked for. You can unsubscribe anytime.
• Basic operation. Like most websites, we may process limited technical data (such as IP address and basic logs) to keep the Service running, secure, and reliable. We use minimal, privacy-respecting analytics where applicable.
• We don’t sell your data. Ever.
• Your choices. You can stop using any feature at any time, clear local data in your browser, and request deletion of any community data tied to you.
