Privacy policy

Last updated: September 17, 2026

playgrid.cc is a static educational website about sound synthesis and sound shaping. You can read the tutorials and play the audio examples without creating an account or submitting personal information.

Information processed when you visit

Like most websites, playgrid.cc and its hosting provider receive the technical information needed to deliver a page or file. This can include the requested URL, date and time, IP address, browser or device information, and security-related request data. This information is used to deliver the site, maintain reliability, prevent abuse and investigate security incidents.

The production site uses Google Analytics 4 to understand aggregate site usage. Google Analytics may use first-party cookies, including _ga, and process information such as pages viewed, interactions, referring pages, approximate location, browser, device, operating system and language. Google receives an IP address as part of the network request; Google states that Analytics uses it during collection and does not log or store the raw address. playgrid.cc does not send names, email addresses or account identifiers to Google Analytics.

Analytics is used to understand which tutorials are useful and to improve the site. It is not used to provide accounts, run advertising, build user profiles for playgrid.cc, or sell personal information.

Information playgrid.cc does not request

The site has no visitor accounts, comments, contact forms, purchases or newsletter signup. It does not ask visitors for their name, email address, payment information or Facebook login.

Facebook Page publishing

The site owner may use Meta's Graph API to schedule links to playgrid.cc tutorials on a Facebook Page. That publishing process uses the Page owner's credentials and tutorial information from this site. It does not request or store Facebook profile information, posts, friends, messages or other data belonging to site visitors.

If you administer the Facebook Page and previously authorized the publishing app, you can remove its access through Facebook's settings. Locally stored Page credentials and scheduling receipts can also be deleted by the Page administrator. playgrid.cc has no Facebook visitor data to delete.

Service providers

Cloudflare hosts and delivers playgrid.cc and may process request and security data. Google provides the Analytics service described above. These providers process information under their own terms and privacy policies:

Your choices

You can block or delete cookies using your browser settings. Blocking Analytics does not prevent you from reading tutorials or playing audio. Google also provides a Google Analytics opt-out browser add-on.

Because playgrid.cc does not provide visitor accounts or accept personal submissions, it usually cannot identify an individual in its aggregate Analytics reports. Requests concerning data held by Google or Cloudflare can also be made through those providers' privacy controls.

Links to other websites are governed by those sites' privacy practices. This policy applies only to playgrid.cc.

Changes to this policy

This policy will be updated when the site's data practices or service providers materially change. The date at the top identifies the latest revision.
