Learning tools
The checker, suit demo and calculator use temporary page memory. They do not create a visitor account, save a practice history or send selections to the server. Reloading starts again.
Enquiries and sessions
The PHP contact form stores name, email, message and time. Administrators can review, edit or delete messages. A salted IP hash supports rate limiting, while session cookies protect forms and administrator login. The operator should publish real contact details and a retention policy before accepting public enquiries.
External platforms
Share links open an external service with the public website URL. There are no embedded social tracking widgets. Visitors complete sharing on that platform, whose own terms apply. Platform homepage links do not claim we operate an account there.
Optional services
Analytics is off by default. A configured map contacts Google only when loaded by a visitor. The operator must update this notice and applicable consent handling if services are enabled.
