Overview

Web Harmonium Pro is a browser-based harmonium experience for practice, teaching, and melody sketching. This Privacy Policy explains what information we collect, how we use it, and the choices you may have when you use our website, instrument, accounts, payments, and support channels.

By using Web Harmonium Pro, you agree to the practices described in this Privacy Policy.

We may collect the following categories of information:

  1. Information you provide directly

    • Examples: your name, email address, account profile details, support messages, and other information you choose to send to us.
    • Why we collect it: to create and manage your account, respond to support requests, and communicate with you about the service.

  2. Usage and technical information

    • Examples: IP address, browser type, device type, operating system, referring pages, approximate location derived from IP, and basic interaction or diagnostic data.
    • Why we collect it: to operate, secure, troubleshoot, and improve the website and browser instrument.

    • Examples: purchase status, order identifiers, billing country, and plan details.
    • Why we collect it: to process purchases, prevent fraud, and manage subscriptions or credits.
    • Important note: payment card details are typically processed by third-party payment providers and are not stored by us unless explicitly stated during checkout.

  4. Cookies and similar technologies

    • Examples: cookies, local storage, and similar tools used for session management, preferences, analytics, or sign-in state.
    • Why we collect it: to keep the service working properly, remember settings, and understand site performance.

  5. Content associated with optional product features

How We Use Information

We use personal information to:

  • provide, maintain, and secure Web Harmonium Pro;
  • authenticate users and manage accounts;
  • process purchases, subscriptions, and related customer support;
  • measure product performance and improve usability;
  • detect fraud, abuse, security incidents, or violations of our Terms;
  • comply with legal obligations and enforce our rights.

Browser Features and Local Processing

Web Harmonium Pro may rely on browser capabilities such as audio playback, local storage, and optional MIDI access. Some instrument interactions may remain local to your browser session. If a feature sends information to our servers, we use that information only for operating the feature, improving reliability, or supporting your account.

How We Share Information

We do not sell your personal information for money. We may share information with:

  • hosting, infrastructure, and security providers;
  • payment processors and billing providers;
  • authentication, email, analytics, or support vendors;
  • professional advisers, regulators, law enforcement, or other parties when required by law or reasonably necessary to protect users, the public, or Web Harmonium Pro.

We may also share aggregated or de-identified information that does not reasonably identify you.

Data Retention

We retain information for as long as reasonably necessary to provide the service, maintain business and tax records, resolve disputes, enforce agreements, and comply with applicable law. Retention periods may vary depending on the type of information and the reason it was collected.

Your Choices and Rights

Depending on where you live, you may have rights to request access to, correction of, deletion of, or export of your personal information, or to object to certain processing. You may also opt out of non-essential marketing communications by using the unsubscribe link in those messages.

To make a privacy request, contact us at hello@web-harmonium.pro. We may need to verify your identity before completing a request.

Data Security

We use reasonable administrative, technical, and organizational safeguards designed to protect personal information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

Children's Privacy

Web Harmonium Pro is intended for a general audience and is not directed to children under 13. If we learn that we collected personal information from a child under 13 without legally required consent, we will take appropriate steps to delete that information.

International Use

If you access the service from outside the country where our operators or service providers are located, your information may be transferred to and processed in other jurisdictions where privacy laws may differ.

Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will post the updated version on this page and revise the effective date above when appropriate. Your continued use of the service after an update becomes effective means the updated policy applies to your use of the service.
