Privacy policy and analytics choices

Local processing

The application runs the drawing, audio synthesis and export code on your device. There is no account system, advertising, session replay or project-upload endpoint. Optional Google Analytics is loaded only after you choose Allow analytics. The hosting service still receives normal web requests and may keep operational logs such as IP addresses and user agents; this is not a promise that browsing creates no server data.

One saved draft

The key pmt-draft-v1 in browser local storage holds one drawing, including its title and settings. Another edited drawing replaces it. Private browsing or clearing site data may remove it. Download a project for longer-term storage.

Use your browser’s site-data settings to delete this data, or use the control below. Clearing the draft does not delete previously downloaded files.

Sharing is your choice

A generated link contains the encoded project in the URL fragment after the # character. That fragment is not part of a normal HTTP request to the host, but anyone or any service you give the full link to can read it. Browser sync, chat services and extensions may handle the complete link. Do not put personal or sensitive information in a shared drawing title.

Optional analytics

With your permission, Google Analytics measures page visits and browser/device information using cookies. We do not send your drawings, project titles or shared project fragments. Advertising signals and personalization are disabled. Your choice is stored as pmt-analytics-consent. Declining leaves the playground fully usable.

You can withdraw permission below. This stops collection in this browser and clears Analytics cookies; it does not erase data already collected by Google.

External websites have their own privacy practices. We use noreferrer on external links. Email contact@playmusictheory.top for privacy questions. Contact messages are forwarded to the site operator’s Gmail inbox; only include information needed for your request.
