Privacy Policy

Last updated: April 9, 2026

HairPreview ("we," "our," or "us") respects your privacy and is committed to protecting the personal data of our users. This Privacy Policy explains how we collect, use, store, and share information when you use the HairPreview mobile application and website (collectively, the "Service").

1. Information We Collect

1.1 Information You Provide

  • Account Information: When you sign in via Google OAuth, we receive your name, email address, and profile picture from your Google account.
  • Photos: You upload selfie photos for AI analysis and hairstyle generation.
  • Payment Information: Credit purchases are processed through Google Play (Android) or Paddle (Web). We do not directly store your full payment card details.

1.2 Information We Derive

  • Facial Feature Data: Our AI analyzes uploaded photos to extract facial measurements, face shape, vertical thirds, horizontal fifths, bone structure, and soft tissue characteristics. This data is used solely to provide hairstyle recommendations and generation.
  • AI-Generated Images: Hairstyle preview images generated by our AI engine based on your photo and selected parameters.

1.3 Automatically Collected Information

  • Device Information: Device type, operating system version, unique device identifiers.
  • Usage Data: App interactions, feature usage patterns, crash reports.
  • Log Data: IP address, access times, pages viewed (website only).

2. How We Use Your Data

We use the information we collect to:

  • Provide the core Service: AI facial analysis and hairstyle generation.
  • Process payments and manage your credit balance.
  • Maintain your Style Journal (history of generated hairstyles).
  • Improve our AI models and Service quality (only with aggregated, anonymized data).
  • Send transactional notifications (purchase confirmations).
  • Ensure security and prevent fraud.
  • Comply with legal obligations.

3. Data Storage & Retention

  • Original Photos: Deleted from our servers within 24 hours of upload. We do not retain full-resolution originals beyond the processing window.
  • Thumbnails: A small thumbnail of your original photo is kept in your Style Journal for reference and is deleted when you delete your account.
  • AI-Generated Images: Stored in your Style Journal until you choose to delete them or delete your account.
  • Facial Analysis Data: Stored as part of your analysis report. Deleted upon account deletion.
  • Account Data: Retained while your account is active. Upon deletion request, all personal data is permanently removed within 30 days.

4. Third-Party Services

We use the following third-party services:

  • Google OAuth: For user authentication. Subject to Google's Privacy Policy.
  • Google Gemini AI: Powers our facial analysis and image generation engine. Photos are transmitted securely for processing and are not retained by Google for model training.
  • Cloudflare R2: Secure, encrypted storage for images and generated content.
  • Google Play Billing / Paddle: Payment processing. We receive transaction confirmations but do not handle raw payment card data.

5. Cookies & Tracking (Website)

Our website uses essential cookies only — for session management and security. We do not use third-party advertising trackers. Analytics, if implemented, use privacy-respecting, aggregated methods.

6. Your Rights

Depending on your jurisdiction (including GDPR for EU/EEA residents and CCPA for California residents), you have the right to:

  • Access the personal data we hold about you.
  • Rectify inaccurate personal data.
  • Delete your personal data and account ("right to be forgotten").
  • Export your data in a portable format.
  • Restrict or object to processing of your data.
  • Withdraw consent at any time (where processing is based on consent).

To exercise any of these rights, contact us at support@hairpreview.app. We will respond within 30 days.

7. Data Security

We implement industry-standard security measures including encrypted data transmission (TLS 1.3), encrypted storage at rest, access controls, and regular security audits to protect your personal data against unauthorized access, alteration, disclosure, or destruction.

8. Children's Privacy

HairPreview is not intended for users under the age of 13. We do not knowingly collect personal data from children. If we discover we have collected data from a child under 13, we will promptly delete it.

9. International Data Transfers

Your data may be processed in countries outside your own. We ensure appropriate safeguards (such as Standard Contractual Clauses) are in place for any cross-border data transfers.
