Privacy Policy

1. Information you provide

The App may access files and content that you choose, including:

• Audio and video files selected for vocal or stem separation.
• Photos and videos selected for karaoke slideshows.
• Lyrics, timing information, recordings, edits, and exported files you create.
• Messages you send when contacting us for support.

Media processing and project storage are performed on your device unless you explicitly choose an online feature such as AI Lyrics.

2. AI Lyrics and online processing

When you choose AI Lyrics and give consent, the App may send the separated vocal audio, selected language, technical request information, an installation identifier, and subscription-validation data to our processing service. This information is used to transcribe lyrics, prevent abuse, and enforce usage limits.

Our processing infrastructure may use Cloudflare and third-party AI transcription providers such as Groq or Cloudflare Workers AI. We do not intentionally retain the uploaded audio after completing the transcription request, but service providers may process technical logs and request data under their own policies and legal obligations.

3. Device permissions

The App asks for device permissions only for these purposes:

• Photos and media: only when you choose songs or videos to separate, photos or videos as karaoke backgrounds, or save and share what you made.
• Microphone: only while you record yourself singing over the music.
• Camera: only when you choose to sing on camera. The front-camera video is recorded and kept on your device.

4. Purchases and subscriptions

Purchases are processed by Apple through the App Store. We do not receive or store your complete payment-card or bank-account details.

We use RevenueCat to manage subscriptions and Premium access. RevenueCat may process an anonymous app-user identifier, product and transaction identifiers, subscription status, purchase and expiration dates, App Store receipt information, and technical device or app information necessary to provide and maintain purchase functionality. See the RevenueCat Privacy Policy.

5. Usage analytics and crash reports

To learn which features work and to fix problems, the App sends anonymous usage events (for example: onboarding finished, a song separated, the paywall opened, a plan chosen, a purchase completed or cancelled, a score shown or shared, a video exported or failed) and crash and error reports to our own service, hosted on Cloudflare. We do not use third-party analytics, advertising or crash-reporting SDKs.

Each event carries a random installation identifier created by the App (a new one after reinstalling), the app and iOS version, language, subscription plan (free, weekly or yearly) and simple details such as durations or scores. It does not include your name, email, contacts, advertising identifier, the content of your files or recordings, or precise location, and we do not store IP addresses with it. Crash reports come from Apple’s MetricKit and describe where the App failed. This data is not linked to your identity, not used to track you across other apps or websites, and kept for up to about 90 days.

You can turn this off at any time in Settings → “Share anonymous usage & crash data”; events waiting on your device are then deleted and the installation identifier is replaced with a new one, so data sent before and after cannot be linked.

6. How we use information

We use information only as reasonably necessary to:

• Provide music separation, karaoke creation, lyrics, export, and related features.
• Process purchases, restore subscriptions, and unlock Premium features.
• Apply usage limits, prevent fraud or abuse, diagnose failures, and secure the App.
• Understand, in aggregate, how features are used and improve the App.
• Respond to support requests and comply with applicable law.

7. Sharing and service providers

We do not sell your directly identifying personal information. Information may be shared with service providers only for the purposes described above, including Apple, RevenueCat, Cloudflare, and AI transcription providers. We may also disclose information if required by law, to protect users, or to investigate fraud, security incidents, or violations of applicable terms.

These providers may process information in countries other than your own and are governed by their respective privacy policies.

8. Retention and security

Projects and exported media remain on your device until you delete them or uninstall the App, subject to device backup behavior. Usage counters, subscription records, and limited technical logs may be retained for as long as needed to provide the service, prevent abuse, meet accounting requirements, resolve disputes, or comply with law.

We use reasonable administrative and technical safeguards, but no electronic storage or transmission method can be guaranteed to be completely secure.

9. Your choices and rights

• You control which media files and device permissions the App can access.
• You may decline AI Lyrics consent and continue using supported on-device features.
• You may turn the photos, microphone, or camera permission off in iOS Settings.
• You may manage or cancel subscriptions through your Apple account settings.
• You may delete local projects and exported files from the App or your device.
• You may turn anonymous usage and crash reports off in the App’s Settings.
• You may contact us to request access, correction, or deletion where applicable.

10. Children’s privacy

The App is not directed to children under 13, or the minimum age required by local law. We do not knowingly collect personal information from children without legally required consent. If you believe a child has provided personal information, contact us so we can investigate and take appropriate action.

11. Changes to this policy

We may update this Privacy Policy to reflect changes to the App, service providers, or legal requirements. The updated version will show a revised effective date. Material changes may also be communicated in the App where appropriate.
