Who runs the platform
Zero to Dev is run by Ravil Yahyayev, the teacher of the course. For anything about your data, write to ravil.yahyayev@gmail.com.
What we receive from Google
You sign in with your Google account. Google sends us your name, email address and a link to your profile picture. We never see or store your Google password.
What the platform stores
Your lesson progress (checkpoints, homework you tick, finished lessons), your quiz and exam answers and scores, the class you joined, and when you last signed in.
Why
To sign you in, keep your progress on every device, grade quizzes and exams, and let your teacher see the progress and results of the students in their class. Nothing else: no advertising and no profiling.
Cookies
One cookie keeps you signed in and one remembers your language. There are no advertising, tracking or analytics cookies.
Who can see it
Your teacher sees your name, email, progress and results. We do not sell or share your data with anyone else. It is stored on our own server in the European Union. Google handles the sign-in itself, under its own privacy policy.
How long we keep it
As long as you have an account. A backup of the database is made every night and kept for 14 days.
Your rights
You can ask for a copy of your data, for it to be corrected, or for your account and all its data to be deleted. Write to ravil.yahyayev@gmail.com and it will be done within 30 days. If this policy changes, the date at the top changes too.
