Privacy and local records

You can browse and practise without an account. Course selection, practice history, local event records and settings are stored in this browser. Clearing browser storage removes them; another device does not receive them automatically.

Usage collection is off by default. If you turn it on, configured server collection receives event categories, qualification and family identifiers, result categories and whether assistance was used. It does not receive your answer, name or a persistent visitor identifier. Do Not Track and Global Privacy Control stop this optional transmission.

Saving a mathematical problem report keeps its description and question reference locally. Where the report collector is configured, it also sends those fields to the site. Do not include personal information in a report.

A report is saved in your browser first. The message “Report received” confirms that the server has received it too. When server collection is enabled, anonymous events and reports are kept in private storage for up to 30 days.
