Effective July 20, 2026
This page covers the Piano 1024 web app at piano1024.com — the two-manual browser piano synthesized live on your device. It has no account and no login, and we collect no personal data ourselves; the only data handling comes from the ads and analytics described below, and almost everything you do stays on your own device.
Piano 1024 is one of the services operated by Chardonn.AI. This page is the piano-specific policy; the full company privacy policy, covering all of our apps, lives at chardonn.ai/privacy and governs wherever this page is silent.
Piano 1024 never asks you to sign in and does not collect your name, email address, or any account information. You just open the page and play.
localStorage and never leave your
device. You can clear them at any time by clearing this site's data in your browser.The web app displays ads served by Google AdSense. To serve and measure ads, Google may collect data such as device identifiers, cookie data, and IP addresses; this information is collected directly by Google. Ads are placed so they never touch the playing surface — the mobile-landscape play mode is entirely ad-free.
You can learn more in Google's Privacy Policy and manage personalized ads at Google Ads Settings.
To understand how the instrument is used and to improve it, the web app uses Google Analytics 4 for aggregate usage, and Microsoft Clarity, which captures anonymized interaction data such as heatmaps and session replays. These tools use cookies or similar technologies; device identifiers and IP addresses may be processed by their providers. See Google's Privacy Policy and the Microsoft Privacy Statement.
In these regions, advertising cookies are not set and the analytics and session-replay tools do not start until you make a choice in the consent dialog — a Google-certified consent management platform — shown on your first visit. You may decline; the piano works identically either way.
You can change or withdraw your consent at any time through the “Ad consent” link in the page footer (on desktop) or on the opening screen (on mobile).
Piano 1024 is a static site hosted on Cloudflare Pages, which may process standard server logs (such as IP addresses) for security and delivery. We keep no server-side database and store none of your data on our own servers.
Piano 1024 also runs as an app inside ChatGPT and Claude at mcp.piano1024.com. That version is a stateless connector: it shows no ads, uses no analytics, keeps no account of its own, and synthesizes all audio live in the widget on your device. Each musical request is processed transiently to build the response and is never stored, logged, or shared.
Piano 1024 is not directed to children under the age of 13, and we do not knowingly collect personal information from children. Because the web app collects no personal data itself, there is nothing for us to delete; advertising and analytics are governed by the providers' policies linked above and, in the regions listed, by your consent choice.
We may update this policy from time to time; changes take effect once posted here, and the effective date above will reflect them. Questions or inquiries are always welcome at [email protected].
