Privacy Policy
Last updated: Feb 28, 2026
This Privacy Policy explains how we collect, use, and protect your information when you use our AI nail design application (the "Service").
1. Information we collect
Account data
Basic profile information from Clerk (such as email and user ID) used to create your user record and credit balance.
Uploaded photos
Hand / nail photos you upload in order to generate designs. These images are processed by our AI providers and may be temporarily stored for processing and safety checks.
Usage data
Non-sensitive analytics such as feature usage, approximate timestamps, and anonymized technical information about your device and browser.
2. How we use your information
We use your information to:
- Provide and improve the AI nail design experience.
- Manage your credits and track usage.
- Secure accounts and prevent abuse or fraud.
- Analyze aggregated usage to improve the product.
3. Payments
Payments are processed securely by third-party payment providers such as Stripe. We do not store or have access to your full payment card details.
4. AI providers and data processing
We use third-party AI providers (such as OpenAI) to generate nail designs. Your uploaded images and prompts may be sent to these providers solely for generating results.
We do not sell your images or prompts.
5. International data transfers
Because our service providers may operate globally, your information may be processed in countries outside your country of residence. We take reasonable steps to ensure appropriate data protection safeguards are in place.
6. Data retention
We keep your account and credit data while your account remains active.
Uploaded and generated images may be retained for a limited period for quality, debugging, and abuse-prevention purposes, after which they may be deleted or anonymized.

Depending on your location, you may have the right to access, update, or delete your personal data.
