Terms of use

Effective September 8, 2026

These terms cover official Intoniva Android builds and the project website published under the MajkeyLab name. Contact: majkeylab@gmail.com.

Using the app

You may install and use official, unmodified Intoniva builds on devices you own or control, for personal or professional music activities. The app is free, with no account, subscription, or in-app purchase. Android 8.0 or newer is required; some platform features depend on your Android version and device.

Microphone access is needed for live tuning. Auto-scroll is optional and needs separately enabled Android permissions. You can stop using a feature or revoke its permission in Android settings.

Software and content rights

Intoniva remains proprietary software. Permission to use official builds does not grant ownership or permission to modify, resell, sublicense, or redistribute the app, source code, or original assets, except where applicable law or platform terms provide otherwise. See the software licence and third-party notices.

You keep your rights in files you select. Use audio you are entitled to access and analyze. Intoniva does not grant rights to another person’s music, recording, lyrics, or sheet music. Downloading the app does not make those works free to redistribute.

Analysis and testing builds

Pitch, chord, note, and tempo results are computed estimates. Check results against the recording before relying on them. Noise, distortion, overlapping instruments, and ambiguous harmony can affect results. Testing builds may contain faults; error-free operation, a particular transcription accuracy, and uninterrupted availability are not guaranteed.

Privacy, payments, and external services

The privacy policy explains local processing and optional support. The refund policy covers the free app and optional external support payments. GitHub, Google Play, and payment providers apply their own terms when you use their services.

Your legal rights

Nothing in these terms excludes mandatory consumer rights, statutory remedies, or liability that cannot lawfully be excluded. Any licence disclaimer applies only to the extent permitted by applicable law. These terms do not impose mandatory arbitration or waive access to courts or regulators.

Changes and contact

The effective date identifies the current terms. Material changes will be described with an updated date before the affected release. Contact majkeylab@gmail.com for support, privacy requests, or permission to use proprietary project materials.
