Local and temporary tools
Player names and score events remain in this browser’s local storage. The board does not send them to the server. Reset clears the saved record after confirmation; exported CSV files stay where you save them. Calculator selections and practice answers use temporary page memory and reset on reload.
Enquiries and sessions
The PHP contact form stores name, email, message and time. Administrators may review, edit or delete messages. A salted IP hash supports rate limiting; session cookies protect forms and administrator login. The operator should publish real contact details and a retention policy before accepting public enquiries.
External services
Share links open a platform with the public site URL, without embedded social tracking widgets. Visitors finish sharing there. Analytics is off by default and a configured map contacts Google only when loaded. Enabled services require an accurate privacy notice and applicable consent handling.
