When you take a selfie for a skin analysis, where does that photo actually go? Most skin apps upload your image to a remote server — where it may be stored, processed by third-party AI vendors, and retained for model training or analytics. For something as personal as a close-up photo of your bare face, that's a significant privacy trade-off that most apps don't make obvious.
Rosee was built differently from the ground up. Every analysis — hydration, glow, texture, skin tone, undertone, dark circles, redness — runs entirely on your iPhone using on-device machine learning. Your photo is analyzed in place and then discarded. It never travels over a network, never touches a cloud server, and never sits in a database somewhere. That's not a marketing claim; it's how the architecture works.
If skin privacy matters to you — whether you're cautious about biometric data, wary of data breaches, or simply prefer that your face stays on your phone — Rosee is designed specifically for that. You still get a full, science-backed skin assessment with CIELAB color science for tone and undertone, honest lighting-aware scoring, and a progress log that lives only on your device.
