The only hand that matters is yours.

Why try-on changes the decision

Nail regret usually is not about the artist — it is about committing to a design you had only ever seen on someone else. Length that looked elegant online feels impractical on your hands; a colour that glowed against one skin tone sits differently against yours.

With Nailly you take one photo of your hand, and every design — yours or one you found in the app — can be tried on it. Swap shapes, lengths, colours and finishes and watch them change on your real hand until it is right.

Your photo stays on your phone. Full stop.

This is the part we are proudest of: hand photos are processed entirely on your device. They are not uploaded, not stored on our servers, not used to train anything. A photo only leaves your phone if you yourself choose to share it.

That is not a settings toggle you have to find — it is how the feature is built. You can read it in plain language in our privacy policy, which says exactly this.

From "maybe" to booked

Once the design looks right on your hand, you are no longer guessing. Save it, keep iterating, or post it to your city's "Who can make this?" board and let real artists claim it, quote it, and book you in.

Walking into an appointment already knowing the set suits your hands changes the whole experience — for you and for the artist.
