Creating a Tarc account lets your progress sync across devices, unlocks the global leaderboard and public profile, and backs up your data server-side.
Tarc does not use traditional email-and-password sign-up. There is no password to set, and Apple Sign-In is not currently available.
The first time you sign in, you'll be asked to choose a username (up to 20 characters). This is separate from your display name, which defaults to your username but can be changed later in your profile.
If you were using Guest Mode before signing up, your existing local progress — XP, streak, achievements, completed lessons — is merged into your new account automatically. You don't start over.
Your account data (profile, progress, achievements) is stored via Tarc's backend (Supabase) and syncs across any device where you sign in with the same account — see Cloud Sync.
No — Tarc uses Google sign-in or email-based one-time codes/magic links, with no password to create or remember.
Not currently — Google and email are the two available sign-in methods.
No — your existing guest progress is automatically merged into the new account during sign-up.
Your username is set at sign-up; your display name (shown by default as your username) can be edited afterward in your profile.
