01Purpose
These terms govern the use of the Piano One app and the piano-one.com website. By using the app, you accept them.
02Personal use
Piano One is for personal, non-commercial use. Your subscription is tied to your App Store or Google Play account: it cannot be shared beyond the family sharing those stores offer, nor resold.
Children under 15 must use Piano One with the consent of a parent or legal guardian.
03Subscription and payment
Some lessons are free. Full access requires a Piano One Premium subscription:
Free trial
If you are offered a trial, you pay nothing before the end of the stated period.
Automatic renewal
The subscription renews at each term unless cancelled at least 24 hours before.
Cancellation
From your App Store or Google Play account settings. Access stays active until the end of the paid period.
Refunds
They are handled by Apple or Google under their own terms.
04Acceptable use
You agree not to bypass the app’s protections, extract its content, or use it in any way that could harm the service or other users.
05Intellectual property
Piano One grants you a personal, non-exclusive and non-transferable right to use the app. The content remains the property of Piano One or its authors.
06Liability
We do everything we can for Piano One to work well, everywhere. Note recognition may still vary with your instrument, your device and the acoustics of the room.
Tune your piano.
A badly out-of-tune piano can throw off note detection. If a result feels unfair, our Help centre explains how to calibrate listening.
07Changes
We may update these terms. If anything important changes, we will let you know in the app at least 30 days in advance.
08Governing law
These terms are governed by French law. In case of dispute, you can use a consumer mediator free of charge before taking any legal action.
