Private learning account
Carry your progress.
Browse the complete library without signing in. Connect Google before playing, then carry local-first progress between devices.
Account status
Your private passport
Private
The same Google action creates a first account or returns you to an existing one. The library remains public; Google authentication is required before play.
Preparing account controls
Public navigation and cards remain available while learning waits for Google.
Why connect
Cross-device continuity
Carry learning history between signed-in devices.
Account recovery
Return to the same private learning identity.
Public all-time standings
Every account receives an editable public name and an all-time mastery entry automatically.
Google stays private.
Your Google name, email, and photo never appear on the leaderboard. Only your editable public name, mastery-tier counts, and casual weighted total are shown.
