At Mister Montuno (hereinafter, "the App"), developed and operated by LEOM MUSIC LAB S.L. (hereinafter, "the Company", "we", "us", or "our"), a company registered in Santa Cruz de Tenerife, Canary Islands, Spain, we respect your privacy and are committed to protecting it in accordance with the General Data Protection Regulation (GDPR) and applicable Spanish data protection laws (LOPDGDD).

This Privacy Policy explains what information we collect, how we use it, and your rights regarding that information.

1. Data Controller

• Company Name: LEOM MUSIC LAB S.L.

• Registered Address: Santa Cruz de Tenerife, Canary Islands, Spain

• Contact Email: contact@playwithpiano.com

2. Information We Collect and How We Use It

We strongly believe in "Privacy by Design" and minimize data collection to the absolute necessary.

A. Non-Personal & Anonymized Analytics

• What we collect: We use Google Analytics for Firebase to understand how users interact with our App (e.g., which musical tracks/stems are played most frequently, sessions duration, and application crashes).

• Privacy compliance: Google Analytics is configured in anonymized mode. This data is purely statistical, aggregated, cannot identify you personally, and does not constitute Personally Identifiable Information (PII).

• Purpose: To improve the technical stability, usability, and musical content of the App.

B. Anonymous Suggestions and Feedback

• What we collect: The suggestions, ideas, or feedback you submit voluntarily through our in-app suggestion form.

• Privacy compliance: This form is 100% anonymous. We do not collect your name, email, device ID, or any other personal identifiers.

C. Subscription and Payment Data

• What we collect: Subscription transactions are processed directly and securely by Apple Inc. (App Store) or Google LLC (Google Play Store).

• Privacy compliance: The Company does not access, collect, or store your credit card details, bank account numbers, or billing addresses. We only receive anonymous transaction confirmations and status updates (active/expired) from the app stores to unlock your Premium features.

3. Legal Basis for Processing

Our legal basis for processing anonymous usage data is our legitimate interest (Art. 6.1(f) GDPR) to maintain, secure, and optimize the music player engine and app content.

4. Third-Party Services

The App utilizes the following third-party services which comply with international privacy standards:

• Google Play Services / Firebase: For stability analytics (Crashlytics) and anonymous usage tracking.

• Apple App Store / Google Play Billing: For secure subscription and payment processing.

5. Your Rights (GDPR Compliance)

Under the GDPR, you have the right to access, rectify, or erase any personal data we hold. However, because our analytics are anonymized and our suggestion form is 100% anonymous, we do not hold any personal data that allows us to identify you.

If you wish to stop Google Analytics tracking entirely, you may do so by managing your device's privacy/advertising settings or by uninstalling the App.

6. Account and Data Deletion You may request the deletion of your account and any associated personal data at any time. To initiate this process, please send an email to contact@playwithpiano.com with the subject line 'Account Deletion Request'.

Once received, we will process your request within 30 days. Please note that:

• Your subscription status is managed by the App Store/Google Play Store, so you should also cancel your subscription in your device settings to avoid future charges.

• Since our analytics are anonymized, your usage history cannot be linked back to you once your account identity is removed.
