Dark-pattern classroom
The 19 dark patterns are grouped into four types, following the Korea Fair Trade Commission: sneaking, misdirection, obstruction and pressure. Each type comes with cues to look for and what to do.
Safe simulations
Simulated shopping and subscription screens give you a mission and let you make the choice yourself. If you get stuck, a hint shows what to look at again.
Progress and review
Each mission ends with a score and the safety habits you practiced. The 7-day and all-time records show accuracy, streaks and the types you miss most.
Accessibility
Adjust text size and Korean read-aloud speed, and turn on high contrast or reduced motion. Automatic reading of mission goals and Lina’s spoken encouragement can be switched on or off.
Made for
Older adults who find payment and subscription screens unfamiliar
Families practicing safer smartphone habits together
Community educators teaching practical digital literacy
