A quiet space to learn.

What this preview stores

Your answer counts, latest correct or incorrect answers, completed-session count, and current session are saved in browser local storage. This learning history is not sent to us. There is no learner account, cloud sync, payment processing, or application analytics integration in this build. Different browsers and devices have separate progress.

Your controls

You can clear practice history and the saved session from the progress page. Clearing browser site data also removes them. Private browsing and browser storage settings may prevent saving. If storage is unavailable, the app will show a warning and let you continue practising.

Website delivery

The public preview at prepharbour.com is hosted on Cloudflare Pages. Cloudflare may process technical request information, such as your IP address and browser details, to deliver and protect the website. This is separate from the learning history saved in your browser.

Question reports and support

A question report opens your own email app, addressed to [email protected], with the question reference, cited sources and your note prefilled. Nothing is sent until you send the email. Reports are forwarded through Cloudflare Email Routing to the support inbox, where we receive your email address and the message you chose to send.

We use these messages to investigate questions and respond to support requests. Please leave out licence numbers, identity documents and other sensitive information. You can contact the same address to ask about a report or request deletion of the email you sent. Your email provider also handles the message under its own privacy practices.

Official-source links

Opening an official source takes you to another website. That website receives your request and has its own privacy practices.
