Privacy & cookies

The short version: we collect as little as possible, we don't sell anything, and the Sandbox never sees your data.

The short version

What we collect

Because there are no accounts and nothing to sign up for, we don't ask you for personal information to browse the site or use the free material. The only information we handle is basic, privacy-first website analytics, described below.

Analytics

We use privacy-focused web analytics (Cloudflare Web Analytics) to understand roughly how many people visit and which pages are useful. This is aggregate and does not use tracking cookies or build a profile of you. It records general signals such as page views, the referring site, approximate country, and device type. We use it only to improve the site.

The Sandbox tool

Runs on your device

When you use the Sandbox, the file you load is read and processed inside your own web browser. It is never uploaded to us or to any server. We have no access to it, and nothing about its contents leaves your device. Closing the tab clears it.

Cookies

We don't use cookies to track you or to advertise. Our hosting provider (Cloudflare) may set strictly necessary cookies to keep the site secure and running. Your browser settings let you manage or block cookies if you wish.

Third parties we rely on

Contacting us

If you choose to contact us (for example, to ask a question or request a demo), we'll use the details you provide only to respond to you. We won't add you to a marketing list without your clear agreement.

Your choices

You can browse and learn here without giving us any personal information. If you've contacted us and want to know what we hold or want it deleted, just ask and we'll sort it out.

Children

This site is intended for a general professional audience and is not directed at children.

Changes

If we update this notice, we'll change the "last updated" date above.
