Private learning account
Carry your progress.
Study the complete library on this device without signing in. Connect Google when you want a private account for cross-device progress and recovery.
Account status
Your private passport
Private
The same Google action creates a first account or returns you to an existing one. Authentication never replaces or unlocks the library.
Preparing account controls
Guest navigation, cards, and learning remain available.
Why connect
Cross-device continuity
Carry learning history between signed-in devices.
Account recovery
Return to the same private learning identity.
Optional community
Join the leaderboard later with a separate name you choose.
Google stays private.
Your Google name, email, and photo are never your public leaderboard identity. Nothing is published without a separate choice.
