Privacy Policy

1. Scope and contact

This policy explains how NovaSound Labs, an independent individual developer project behind HandSplit Piano (“we”), handles personal data when you use the App, visit handsplitpiano.com, or contact support. New sales are offered only through the platform stores. The store listing and receipt identify the seller and billing provider as required for that transaction.

2. Local musical processing

• MIDI files and musical content are processed locally on your device.
• The licensing service does not receive your MIDI files or audio.
• HandSplit Piano does not upload or remotely store your MIDI files or audio.

3. Data we process

We may process basic website and service security data, such as network address, device or browser information, requested endpoint, and timestamp. For store entitlement activation, we process the platform, product identifier, store transaction or purchase token, a pseudonymous device identifier, license status, and limited audit data. Store credentials are sent to Apple, Google, or Microsoft for verification. We do not receive or store a full payment-card number. If you contact support, we process the email address, message, store receipt or order reference, and any files or logs you voluntarily provide.

If you separately opt in to App product analytics, we process a random analytics installation identifier, a random session identifier, App version, platform, broad device class, language, plan category, feature interactions, success or failure outcomes, coarse count and duration ranges, broad export settings, and broad purchase-flow outcomes. These analytics are kept separate from license and support records.

Product analytics never include MIDI or audio content, note sequences, file or folder names or paths, song titles, email address, name, license keys, store receipts or tokens, payment data, advertising identifiers, or precise location.

4. Why we process it

• Deliver and secure the App, website, and license service.
• Verify store purchases, restore access, limit devices, and respond to refunds.
• With optional consent, understand which broad features are useful, where workflows fail, how settings are used, and how the purchase flow can be improved.
• Respond to support, privacy, and product questions.
• Diagnose technical issues, prevent fraud and abuse, and meet legal obligations.

Legal bases may include performance of the store purchase, legitimate interests in security, reliability, and support, legal obligations, and consent where applicable law requires it. App product analytics rely on your optional consent.

5. Providers and sharing

We do not sell or rent personal data or use it for behavioral advertising. We disclose only what is necessary to Apple App Store, Google Play, Microsoft Store, website and license-service hosting, security, and support-email providers, or to authorities and other parties when required by law or necessary to protect rights and security. Providers may process data outside your country under their terms and applicable transfer safeguards. Stripe remains an inactive legacy integration and is not offered for new checkout.

6. Cookies, analytics, and advertising

The App does not use behavioral advertising or track how you use musical files. Optional first-party App product analytics are off by default and start only after you choose to enable them. You can withdraw consent in Privacy & Analytics without losing App functionality. Turning analytics off clears the local analytics identifier and sends a deletion request for events associated with that identifier. We do not use third-party advertising SDKs, combine our optional product analytics with a license or identity, build advertising profiles, or sell personal data.

On Android, Google Play Billing may send operational and diagnostic data to Google, including API results, connection information, and device and app metadata. This store billing telemetry operates independently of the optional product-analytics setting in HandSplit Piano.

The public website may use Google Analytics to measure aggregate traffic, page interactions, downloads, and video engagement so we can improve reliability, content, and performance. Where consent is required, non-essential website analytics remains disabled until the visitor allows statistics cookies. Strictly necessary technical and security cookies may operate without analytics consent. App stores and linked services are separate and may use cookies under their own policies.

7. Retention

Raw App product-analytics events are automatically deleted after 90 days and may be retained longer only in aggregated form that no longer identifies an analytics installation. Website security and support records are kept only as long as reasonably necessary for security, reliability, support, legal obligations, or legal claims. When deletion is requested or App analytics are disabled, we delete or anonymize eligible data unless retention is required or permitted by law.

8. Security

License-service connections use HTTPS. License credentials are cryptographically signed, recovery credentials are stored in protected form, and local credentials use secure operating-system storage where available. We limit collection and access and use safeguards appropriate to the risk, but no system is completely secure.

9. Your rights

Depending on your location, you may request confirmation and access, correction, portability, anonymization, restriction or blocking, and deletion of eligible data; information about sharing; or object to certain processing. Where processing relies on consent, you may withdraw it. You may complain to the competent authority, including Brazil’s ANPD where applicable.

Send a request to the email below. We may request enough information to verify your identity and protect the license from unauthorized changes.

10. Children

The App is not designed to collect a child’s musical files or behavior. A child should not make a store purchase or send personal data to support without the involvement of a parent or legal guardian. A guardian who believes a child provided personal data should contact us.

11. Changes

We may update this policy as the App, providers, or legal requirements change. We will revise the date above and provide additional notice when required.
