Privacy Policy

Introduction

Tintback ("we," "our," or "us") respects your privacy and is committed to protecting your personal data. This privacy policy explains how we collect, use, and safeguard your information when you use our iOS application.

Information We Collect

We collect the following information:

• Device Identifier: A unique identifier for your device, used to maintain your account and prevent abuse.
• Photos: Images you upload for colorization processing.
• Usage Data: Anonymized data about how you interact with the app, which cannot be tied back to you personally.

We do not collect your email address or any other personal contact information.

How We Use Your Information

Your information is used to:

• Provide photo colorization services
• Maintain your photo gallery and account
• Process credits and purchases

Photo Storage and Processing

Your photos are stored securely on Cloudflare R2 cloud storage. Photos are processed using Google's Gemini AI service to apply colorization. Your photos remain stored as long as you maintain your account.

Use of Photos for Marketing

Before and after photos generated using free credits may be used by Tintback within the app, on our website, and in marketing materials to showcase our colorization capabilities. If you prefer your photos not be used for marketing purposes, please use purchased credits for your colorizations.

AI Training

Some photos may be used to train and improve our AI colorization models. This helps us provide better results for all users. Photos are processed in aggregate and your individual identity is never associated with training data.

Third-Party Services

We use the following third-party services:

• Google Gemini: AI processing for photo colorization
• Cloudflare R2: Secure cloud storage for photos
• RevenueCat: Payment and subscription management
• Apple: App Store purchases and device verification

These services receive only anonymized data that cannot be tied to your identity.

Your Rights

You have the right to:

• Access your stored photos through the app
• Delete individual photos at any time
• Delete your entire account and all associated data
• Request information about what data we hold

Data Security

We implement appropriate technical and organizational measures to protect your data, including encrypted storage and secure transmission protocols.

Children's Privacy

Our service is available to users of all ages. We do not knowingly collect data specifically from children. Parents and guardians should monitor their children's app usage.
