Privacy Policy

Last updated: 6/8/2026

Introduction

This Privacy Policy applies to Web Harmonium at https://web-harmonium.com. We respect your privacy and are committed to transparency about how this site operates and what data is processed.

What We Collect

We operate a free web-based musical instrument application. Here's what we may collect:

  • Basic Server Logs: IP address, user agent, and referrer for security and troubleshooting.
  • Analytics: We use analytics to understand aggregate traffic and site performance. This data is processed by providers under their policies.
  • Local Storage: Your preferences (volume, reverb, octave settings) may be saved locally in your browser. This data never leaves your device.

Information You Provide

If you contact us by email, we will receive your email address and any information you include in the message. We only use that information to respond to your request and provide support.

What We Don't Collect

  • No account registration required
  • No audio or MIDI data is recorded or transmitted
  • No sensitive personal information collected
  • No data sold to third parties

Web Audio and MIDI

The harmonium uses the Web Audio API and optionally the Web MIDI API for sound generation and MIDI device input. All audio processing happens entirely in your browser. No audio data, MIDI signals, or musical input is transmitted to our servers.

Analytics and Measurement

We use privacy-conscious analytics to understand which pages perform well and how users interact with the instrument. This data is aggregated and does not identify you personally.

Advertising and Cookies

We may display ads through Google AdSense. Google and other third-party advertising technology providers may use cookies, local storage, pixels, device identifiers, or similar technologies to serve ads, measure ad performance, limit repeated impressions, prevent abuse, and support personalized and non-personalized ads.

  • Google and third-party advertising providers may process device, browser, location, interaction, and advertising data under their own policies.
  • You can manage cookie behavior through your browser settings, block or delete third-party storage, and use browser privacy controls where available. Blocking cookies or scripts may affect site features or advertising behavior.
  • You can learn how Google uses data from sites and apps that use its services at https://policies.google.com/technologies/partner-sites.
  • You can review or opt out of many personalized advertising programs through browser controls and by visiting https://www.aboutads.info/choices or https://www.youronlinechoices.com.
  • Some ad providers also offer their own opt-out tools, ad settings, or policy pages; please refer to the provider shown in the ad itself when available.
  • You can also learn more about third-party advertising cookies at https://www.aboutads.info.

Regional Advertising Consent

For users in the European Economic Area, the United Kingdom, or Switzerland, serving Google AdSense ads requires consent handling through a Google-certified consent management platform integrated with the IAB Transparency and Consent Framework v2.3. If that consent management platform is enabled on this Site, you can use it to manage your advertising consent choices and withdraw consent.

Cookies

We use cookies for essential site functionality and analytics measurement. You can manage cookies in your browser settings.

Children's Privacy

Our site is intended for general audiences. We do not knowingly collect information from children under 13.

Your Rights

Since we do not require accounts or store personal profiles, there is minimal personal data to manage. For analytics data, we only use aggregated metrics and do not maintain individual user profiles.

Your Choices

You can disable cookies in your browser, block third-party scripts, or clear local storage to remove saved preferences. Some features may not work as expected if cookies or scripts are blocked.

Data Retention

We retain server logs and analytics data only as long as needed for security and site operations. Instrument preferences stored in your browser remain until you clear them.

Security

We apply reasonable safeguards to protect the site and its data, including HTTPS encryption, access controls, and monitoring. No website can guarantee absolute security, but we take it seriously.

Changes

We may update this policy occasionally. Changes will be posted on this page.
