Privacy policy

What we collect
- Class records: the class name and decks an instructor chooses, and a one-way hash of the instructor key. We never store the key itself.
- Student records: the display name a student types when joining, which cards they answered, whether each answer was correct, and when. No email address, password or other contact details.
- Email: if you email us, your address and what you write. We use it only to reply.
- Practice on your own: stored only in your browser. We never receive it.
What we do not collect
No analytics, advertising or tracking cookies, and no health or patient information. Students should not enter anything other than the name their instructor asks for.
Who can see student results
Only someone holding the class's private instructor link. Students see only their own progress. We do not sell, rent or share student data, or use it for advertising.
Keeping and deleting data
Instructors can remove a student or delete a class and all of its results at any time from the dashboard; deletion is immediate. We may delete classes that have been inactive for more than 12 months. A student can ask their instructor, or contact us, to have their record removed.
Schools
When a school uses Quizzleaf, we process student records only to provide the service to that school and under its direction.
Service providers
Cloudflare hosts the site and stores class data (Cloudflare Workers and its D1 database). Email you send us is handled by Google (Gmail). Each processes data only to provide its service.
Children
Quizzleaf is for students in nursing and pharmacy technician training and is not directed to children under 13.
