Privacy policy

Effective: 10 October 2026

What the public website stores

On your device, this website stores only your color-theme preference using browser localStorage. The chosen language appears in the URL. Simulations run locally in your browser. The public website does not provide visitor accounts, payment processing, advertising code or a contact form at present. The administrator area uses a secure session cookie and stores hashed administrator credentials outside the public web directory.

Hosting and technical logs

The web hosting provider may process request metadata, including IP addresses and technical logs, for delivery and security. The site operator should review and update this policy if analytics, advertising, accounts, contact forms or other data-processing tools are introduced.

External links

Links to NANDAX and Games4Studies lead to independent sites with their own policies. The simulator itself loads no third-party fonts, scripts or trackers.

Children and advertising

The free website does not knowingly request personal information from children. No advertising has been enabled. Advertising is not activated by simply publishing a lesson or linking to a NANDAX product. Additional disclosures and controls will be required before launching advertising or accounts, including compliance with applicable child and data protection requirements.
