Privacy notice

What we collect: your name, your email address, the answers you submit and when you submitted them, and the classes you join. Nothing else.

Why: to show your progress, to show your teacher the progress of students in their class, and to improve the questions.

Who can see it: you, the teacher of any class you join (your name and your results only), and the site administrator. We never sell your data or show advertising on practice pages.

Where it's stored: in a database hosted in Singapore, protected by access rules so each person sees only their own data.

How long: until you ask us to delete it, or two years after your last sign-in.

Your rights: you can ask to see, correct or delete your data at any time. Contact the Data Protection Officer, Steven Riss, at privacy@econrizz.com.
