QuantOS collects account information, training activity, and first-party event logs needed to run the product. We do not sell personal data or use third-party advertising analytics.
Data We Process
We store your name, email, username, password hash, public profile settings, problem submissions, bookmarks, mental math rounds, aggregate stats, and basic product events.
Public profiles show display name, username, join date, track, aggregate stats, badges, and recent solved problems when public profiles are enabled.
