Your data controls
Lumen stores progress and preferences on your device by default. Core practice does not require a gLitCh Labs account. These instructions follow the existing Privacy Policy.
Update your profile
In Preferences, you can change your name, grade, theme, and goals. You can also remove or replace the optional profile photo.
Reset local progress
Preferences includes Reset app, which clears this device’s name, picture, preferences, XP, streaks, and quiz history after confirmation.
Resetting the app, uninstalling it, or clearing browser site data removes the local profile. Only do this when you intend to remove that information.
Cloud features
The current Privacy Policy describes platform cloud backup as prepared but not enabled by default. Do not assume that local progress will return after reinstalling.
