Your data controls

Your Lumen learning profile lives on your device. Firebase sign-in and store subscriptions are separate. Here is what each control changes.

Update your local profile

In Preferences, change your nickname, grade, theme and goals, or remove or replace your picture. These changes do not change your Google or Apple profile.

Reset local progress

Open Preferences → Reset app and confirm Reset and start again. This clears the device’s nickname, picture, preferences, XP, streaks, quiz history and local recovery copy, then returns you to onboarding. It does not delete bundled questions.

Resetting cannot be undone. It does not delete your Firebase account or cancel a subscription. Clearing app or browser storage may also remove local progress; operating-system backups may affect what returns after reinstalling.

Sign out or delete your account

Sign out disconnects the current sign-in and clears current Pro access in the app, but keeps the account and local progress. Delete account requires signing in again with the same provider and deletes the Firebase account. It also keeps local progress. Follow the account-deletion instructions to remove the account and separately clear local data.

Cancel a subscription

Use Manage subscription or open Apple subscriptions or Google Play subscriptions. Reset, sign-out, account deletion and uninstalling do not stop renewal. See Terms of Use for restoration and access limits.

Progress and backups

Signing in does not upload or restore learning progress across devices. Platform cloud backup is not enabled in the current build. Do not rely on signing in or restoring purchases to recover quiz history. Local reset does not delete any separate platform backup that may exist from another build.
