Study record
What you have actually done
Every round, domain set, timed paper and trainer round you finish is kept on this browser and rolled up into accuracy for each of the 9 domains. The most recent 1 is free to read back; the history, the domain accuracy built from it, and the printable sheet are Premium.
Where this lives
In this browser, and nowhere else. There is no account and nothing is uploaded, so the record does not follow you to another machine and clearing site data erases it. That is the trade for a site you can use without handing over an email address.
