We do not sell your data. We share it only with the essential third-party services that power Piano AI:

• Anthropic — AI responses via the Claude API. Your chat messages are processed by Anthropic.
• RevenueCat — subscription and payment management.
• Hetzner — server and database hosting in Germany (EU, GDPR-compliant).
• Sentry — anonymous crash reporting and error monitoring.

We keep your data for as long as your account is active. When you delete your account (Settings → Delete Account), all personal data is deleted within 30 days, except where we are required by law to retain it (for example, HMRC requires us to keep financial records for 6 years).

Under UK GDPR, you have the right to access, correct, or delete your data. To exercise any of these rights, contact us at support@lamininltd.com.

You can delete your account directly in the app via Settings → Delete Account, or via pianoai.online/delete-account.html.

Piano AI is suitable for all ages. We do not knowingly collect additional data from children under 13 beyond what is described in this policy. If you believe a child's data has been collected inappropriately, contact us immediately.

Passwords are hashed using bcrypt. Data is transmitted over HTTPS. Our servers are hosted in GDPR-compliant EU data centres.

Your data is primarily processed in the EU (Hetzner, Germany). AI responses are processed by Anthropic in the US under Standard Contractual Clauses.

We may update this policy from time to time. We will notify you of material changes via the app or by email.

Piano AI is a piano learning application operated by Laminin Ltd, registered in England and Wales. The app provides AI-powered piano tutorials, coaching, and a library of classical music.

You must be 13 or older to create an account. You are responsible for keeping your login credentials secure and for all activity under your account.

You agree not to misuse the service — including attempting to reverse-engineer the app, scrape our song library, or use the AI for any purpose other than piano learning.

Subscriptions are managed via RevenueCat and processed by the relevant app store (Apple App Store or Google Play). Pricing:

By subscribing you authorise recurring charges on your chosen payment method. You may cancel at any time via your device's subscription settings.

New accounts receive a 7-day free trial with full access to all features. No payment is required to start a trial. At the end of the trial, premium features require a subscription — we will not charge you automatically.

You may cancel your subscription at any time. Cancellation takes effect at the end of the current billing period. Refunds are handled according to the relevant app store's refund policy.

The Piano AI app, its design, and AI models are owned by Laminin Ltd. The song library consists of public domain compositions. You may not reproduce, distribute, or commercialise any content from the app.

Piano AI is provided "as is". We do not guarantee uninterrupted service. AI coaching is informational and not a substitute for professional music instruction.

To the maximum extent permitted by law, Laminin Ltd shall not be liable for any indirect, incidental, or consequential damages arising from your use of Piano AI.

These terms are governed by the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.
