Optional, always

Your account 🎒

The school works perfectly without one. Your progress lives in this browser and signing in is never required. Sign in only if you want your lessons, puzzles, XP and quiz scores to follow you between devices. Nothing is harvested, profiled or sold, we store almost nothing, and you can see, download or erase all of it right here. The details are in the one-page privacy promise.

Checking your session…

🎓 One account, both schools This is the same account as the Rusty School's. Sign in at either and your progress follows you to the other: finished lessons, solved puzzles, best quiz scores, milestones, XP and achievements. There is even an achievement (Bilingual 🦀) for learning at both.
📦 What syncing actually includes Completed lessons and puzzles, best quiz scores, and which completions were already counted toward the public banner, so moving between devices never double-counts. That is the entire list. Your playground code never leaves your browser, because the Python in this school runs in your browser.
