A closer look
Slap a filter on your face, and you get sparkle eyes or cat ears—but the app gets something far more valuable: a blueprint of your identity. Your face isn’t just a selfie; it’s as unique as a fingerprint. These free apps often cash in by storing and selling bits of that facial map, sometimes to destinations you’d never approve. It feels like trading a diamond for a plastic toy—you see the instant fun, while the hidden worth slips away quietly. Next time you grin for a quick filter, remember: you might be giving away your digital self-image, no refund attached.
