What we store
Your email and password (hashed, never in plain text), the username you pick, and an optional display name and avatar URL. If you use the app we also store which lessons you have played, the answers you submitted, how confident we are in each skill, and a per-day count of the XP you earned. We record your browser's timezone so streaks roll over at your midnight rather than ours.
What we do with it
We use it to run the product: show your progress, pick what to practice next, and keep your streak honest. Nothing is sold, and nothing is shared with advertisers.
The AI tutor
When you ask the tutor a question, we send that question, the slide you are on, and your answer to Google's Gemini API so it can reply. We do not send your email, name, or anything from other lessons.
We send you a verification email when you sign up, a reset link if you ask for one, and streak reminders. You can turn reminders off in settings at any time.
Your data
Your public profile shows your display name, username, streak, lessons completed and skill mastery. Everything else is private to you. Ask us and we will delete your account and everything attached to it.

Questions about any of this, or you want your account and data deleted: email habibarashad456@gmail.com and we will answer properly.
