Privacy Notice

Last updated: July 28, 2026

MercuryPitch is operated by Irchiinnuss, the data controller. We keep this notice 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. Separation runs on your device by default. If you choose the faster paid option, the audio file you provide is sent to our processing servers, handled only to produce the result you asked for, and kept only for as long as needed to deliver it — then deleted. We never download or “rip” audio from streaming services on your behalf; you always supply the file. We don’t use your audio 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).
• Accounts and sign-in. You can use most of the app without an account. If you sign in, we store the minimum needed to recognise you across sessions (such as an anonymous identifier or, if you provide one, your email) and to keep your credit balance and separated songs associated with you.
• Payments. If you buy credits or make a donation, payment is processed by Stripe. We don’t receive or store your full card number. We keep a record of your purchases, donations, credit balance, and any supporter status (including when it expires) to provide the Service and meet legal and accounting obligations.
• 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.

We may update this notice at any time; when we do, we’ll change the date above. Questions or requests: hello@mercurypitch.com.
