Privacy Policy

Last Updated: January 17, 2026

Welcome to NailLoft ("we," "our," or "us"). Your privacy is our top priority. We have designed our app to process and store your personal creativity locally on your device whenever possible.

1. Information Collection and Storage

A. Local Storage (Core Data)

We prioritize a "Local-First" approach. The following data is stored securely on your device using Core Data and is not transmitted to our servers:

• AI Generated Images: The nail designs you create using our AI tools.
• Favorites: The list of designs you have saved or favorited.
• User Preferences: Your app settings and choices.

Note: Since this data is stored locally, if you uninstall the App or change devices, this data may be lost unless you have enabled iCloud backups for your device.

B. Anonymous Authentication

We use Firebase Anonymous Authentication to grant you access to the App's features without requiring you to provide personal information such as your name, email address, or phone number. You use the App as a "Guest" user.

• We associate a unique, random identifier with your installation to manage your subscription rights (via RevenueCat) and AI usage credits.

C. Public Content

The App displays a collection of public nail art images on the main screen. These images are hosted on Firebase Storage and fetched via Firestore. This is a one-way stream; your personal usage or interactions with these images are not publicly linked to your identity.

2. Artificial Intelligence (AI) Usage

NailLoft utilizes advanced AI models (Google Gemini / Vertex AI) to generate images.

• Input Data: When you use the "Design" feature, the text prompts and style selections you make are sent to the AI provider to generate the image.
• No Personal Training: We do not use your personal data to train public AI models.
• Output: The resulting images are delivered to your device and saved locally.
