Privacy Policy
Last updated: April 2026
Introduction
This Privacy Policy applies to Online Web Harmonium. We are committed to transparency about how this site operates and what data is processed.
What We Collect
Basic server logs (IP address, user agent, referrer) for security and troubleshooting. Anonymous analytics to understand aggregate traffic. Your instrument preferences (volume, reverb, octave) saved in browser local storage — this data never leaves your device.
Information You Provide
If you contact us by email, we receive your email address and the content of your message, used only to respond to your request.
What We Don't Collect
No account registration. No audio or MIDI data recorded or transmitted. No sensitive personal information. No data sold to third parties.
Web Audio and MIDI
All audio processing happens entirely in your browser using the Web Audio API. No audio data, MIDI signals, or musical input is ever transmitted to our servers.
Analytics
We use privacy-conscious analytics to understand which pages perform well. This data is aggregated and does not identify you personally.
Advertising
We may display ads from third-party networks. These vendors may use cookies to measure ad performance. You can manage cookie behavior in your browser settings.
Cookies
We use cookies for essential functionality and analytics. You can manage or clear cookies in your browser settings.
Your Rights
Since we do not require accounts or store personal profiles, there is minimal personal data to manage. You can clear local storage at any time to remove saved preferences.
Data Retention
Server logs and analytics data are retained only as long as needed for security and site operations.
Security
We apply reasonable safeguards 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.
