Privacy Policy

Last updated: March 13, 2026

The Simple Version

Private, on-device detection with no video uploads. We don't collect your data because we never built a way to. This page explains exactly how that works.

What We Don't Collect

We don't collect, store, or send anywhere:

  • Any video or photos from your camera
  • Who you are or what you look like
  • Where you use the app or when
  • Any camera footage or personal habit data uploaded from the desktop app
  • Literally anything off your computer

How It Actually Works

Naily watches for your hand moving to your mouth, using your webcam. It looks at each frame and immediately forgets it—nothing is saved. Think of it like looking in a mirror: the reflection exists only while you're there.

What Does Stay on Your Computer

The only things saved (on your device only):

  • Timestamps: When you bit your nails (just the time, no images)
  • Your settings: Like volume, alert style, and sensitivity

Delete the app, and all of this disappears. It's stored in your app folder—nowhere else.

No Third Parties

Naily uses private, on-device detection with no video uploads. The marketing website uses privacy-friendly analytics to understand page visits, but the desktop app does not send camera footage, recordings, or personal habit logs to us.

Activating the app

To activate the app, you'll need to purchase a license key from our store. Once you have your key, enter it in the app to activate your chosen plan. Activating the app requires an internet connection to verify your license key. After activation, the app works completely offline. Payments go through Lemon Squeezy, and they handle checkout details according to their own privacy rules.

Camera Permission

Naily needs camera access to work (that's the whole point). Your computer will ask for permission the first time. You can turn it off anytime in Settings—but then the app won't be able to help you.

Updates

If we change this policy, we'll update this page and the date at the top. Keep using the app, and you're agreeing to any updates.
