Privacy Policy

Last updated: 2026-09-11

1. Who we are

piano.ai2.fun is an online service for converting piano performance audio and video into interactive piano rolls, notation and related practice materials. The service operator's legal name, address and data-protection contact will be added to this policy before paid service launch.

2. What information we collect

  • Account information: email, username and display name.
  • User content: performance video/audio and derived MIDI, sheet music, chords, beats and related metadata.
  • Usage and device data: page views, feature clicks, playback and practice time, browser information, random browser device ID and session ID. These records may be linked to your account when you are logged in and are not anonymous.
  • Network and security data: information processed by the application, Cloudflare and other infrastructure to deliver, protect and troubleshoot the service. Application usage events use truncated IP information; this does not describe every network or security log.
  • Cookies and local storage: login session, access code, language, local settings, random device ID and recent usage events.
  • Subscription and billing data: orders, subscription status, billing periods, payment and refund amounts and currencies, transaction IDs and payment-provider notifications. These records may include the buyer email.
  • Support communications: messages and contact details you send to support, billing or copyright addresses.

3. Why we use information

  • To provide transcription, engraving, playback, practice, storage and sharing.
  • To secure the service, prevent abuse, diagnose failures and enforce quotas.
  • To understand usage and improve reliability and features.
  • To administer subscriptions, reconcile payments and refunds, and manage paid access.
  • To send necessary account, security and service notices.
  • To respond to support, deletion, export and copyright requests.

4. Legal bases and choices

Depending on your location and the context, processing is based on providing the service you request, our legitimate interests in security and improvement, your consent where required, and legal obligations. You may withdraw consent where processing relies on consent; this does not affect processing already carried out or processing needed for the service or law.

5. Storage, processors and international transfers

We use infrastructure providers for networking and security, database and object storage, email delivery and payment processing. Media is stored privately and served through signed access. Payment credentials are handled by the payment provider; do not send full card numbers or security codes to our support addresses. Providers may process data in countries other than yours. The operator will publish the current provider list, transfer safeguards and data-protection contact in the full policy before paid service launch.

6. Your rights

Subject to applicable law, you may request access, correction, export, deletion or restriction of your personal data, and object to processing where applicable. Email [email protected]; we may verify your identity and the scope of the request. Export and deletion are currently handled by support staff and are not instant self-service operations. We will explain any data we must retain for billing, disputes, security or legal obligations.

7. Retention and account deletion

We retain data for as long as needed to provide accounts, transcription, practice, payment and security functions. Billing, audit, dispute and legal obligations may require longer retention. Fixed periods by data category, backup deletion timing and request-handling deadlines will be published in the full policy. When an account or upload is deleted, copies in backups, processor systems or search indexes may take time to disappear or may be retained where legally required.

8. Children

The service is for learners. Do not use it if you are below the minimum age required where you live. If we learn that we collected an account from a child without the required consent, we will take reasonable steps to delete it and the associated personal data.

9. Changes and contact

We will date policy updates and provide additional notice for material changes where required. Questions about privacy can be sent to [email protected]. The operator identity and address remain items to complete before paid service launch.
