The short version: MIDIMIDI is a subscription piano practice app. You get 7 days free, then you are billed until you cancel, and you can cancel any time in two clicks. Your practice data lives on your device only — back it up, because we cannot restore it.
These terms are between you and MIDIMIDI ("we", "us"). By creating an account or using the app you accept them. If you do not agree, do not use MIDIMIDI.
You need an account to use MIDIMIDI. Keep your password secure and tell us promptly if you believe someone else is using your account. You must be old enough to enter a contract where you live, and at least 13 years old. One account is for one person; do not share your login.
The 7-day trial exists so you can decide before paying anything, so we generally do not refund charges already made. Nothing here limits any refund or cancellation right you have under the consumer law that applies to you. If something went genuinely wrong, contact us — we would rather sort it out.
We may change prices. If a change affects your renewals we will tell you by email before it takes effect, so you can cancel first if you prefer.
You keep all rights to the MIDI files, recordings and other material you load into MIDIMIDI. Because it never reaches our servers, we claim no licence over it whatsoever.
You are responsible for having the right to use what you import. MIDIMIDI is a practice and transcription tool: do not use it to infringe anyone's copyright. The bundled starter arrangement of Für Elise is our own original arrangement of a public-domain composition, and is provided for use within the app.
Do not resell or redistribute the app, share your account, attempt to bypass the subscription or extract the source, disrupt the service, or use MIDIMIDI to break the law. We may suspend or terminate accounts that do these things.
Your songs, practice history, statistics and settings are stored only in your browser. Clearing your browser data, losing the browser profile, or a device failure will erase them permanently, and no copy exists on our servers to restore. Use Settings → Export/Restore to keep your own backups of anything you cannot afford to lose. Your subscription is unaffected by such a loss — it is tied to your account, not your device.
MIDIMIDI includes open-source software and sampled instruments under their own licences, listed in the credits shipped with the app (Settings → Credits). Those licences govern those components.
We work to keep MIDIMIDI available but do not guarantee uninterrupted service; it may be unavailable during maintenance, outages, or events beyond our control. Features may change or be discontinued as the app develops.
MIDIMIDI is provided "as is" and "as available", without warranties of any kind, whether express or implied, to the maximum extent the law allows.
To the maximum extent permitted by law, we are not liable for indirect or consequential damages, or for loss of data described in section 8. Our total liability for any claim relating to MIDIMIDI is limited to the amount you paid us in the 12 months before the claim. Nothing here excludes liability that cannot lawfully be excluded, including your rights as a consumer.
You may stop using MIDIMIDI and delete your account at any time. We may suspend or terminate your access if you materially breach these terms; if we do so without cause, we will refund the unused portion of your current period.
We may update these terms. Material changes will be announced in the app or by email before taking effect, and continued use afterwards means you accept them.
These terms are governed by the laws of Mexico, and the courts of Monterrey, Nuevo León have jurisdiction — except where the consumer law of your own country gives you the right to bring a claim locally.
