1. Information We Collect

Information You Provide Directly

• Account Data: When you first use InkCraft, we create an anonymous account using Firebase Authentication. We do not require your name, email address, or phone number to use the app. Your account is identified by a unique anonymous identifier.
• Profile Information: You may optionally set a display nickname, short bio, gender, and profile avatar image. This information is stored on our servers and associated with your anonymous account.
• Photos and Images: You may upload photos of yourself, reference images, and tattoo designs for AI-powered generation features. These images are transmitted to third-party AI service providers for processing.
• Text Input: You may provide text descriptions, prompts, and messages when using the AI generation features and AI chat assistant.
• Voice Input: If you use the voice input feature in the AI chat, your speech is processed on-device using Apple's Speech Recognition framework to convert it to text. The audio itself is processed locally and is not transmitted to our servers.
• Purchase Information: Subscription and credit purchase transactions are processed exclusively through Apple's In-App Purchase system. We do not directly collect or store your payment card details, billing address, or financial account information. We receive transaction confirmations from Apple to credit your account.

Information Collected Automatically

• Usage Data: We collect information about how you interact with the app, including which features you use, generation history (prompts, settings, results), and timestamps of activity.
• Device Information: We may collect device type, operating system version, app version, and device integrity status for security and service improvement purposes.

Information We Do NOT Collect

• We do not collect your real name, email address, phone number, or physical address
• We do not collect location data
• We do not collect contacts or address book information
• We do not use advertising identifiers or serve targeted ads
• We do not use third-party analytics SDKs (such as Google Analytics, Firebase Analytics, or similar)

2. How We Use Your Information

We use the information we collect to:

• Provide, maintain, and deliver the AI generation services (tattoo visualization, image generation, video generation, face editing, AI chat)
• Process your uploaded images and text prompts through AI generation providers to produce results
• Store your generation history so you can review, save, and manage past results
• Manage your account, credit balance, and subscription status
• Validate uploaded images for safety and compliance with our content policies
• Improve, optimize, and develop new features for the Services
• Ensure security, prevent fraud, and detect abuse
• Enforce our Terms of Use and content policies

3. AI Image and Content Processing

We use automated image validation powered by AI to screen uploaded images for safety and content policy compliance before processing. Images that violate our policies are rejected.

We do not use your personal images or prompts to train, fine-tune, or improve AI models. Your content is processed solely to deliver the generation results you request.

4. Data Storage and Retention

Cloud Storage

• Profile Data: Your anonymous user ID, nickname, bio, gender, avatar, credit balance, subscription status, and generation statistics are stored in Google Firebase Cloud Firestore.
• Generation Results: Generated images are stored in Google Firebase Cloud Storage. Generated videos may be stored temporarily for retrieval.
• Generation History: Metadata about your generations (prompts, settings, timestamps, result URLs) is stored in Cloud Firestore.

Local Storage

• Secure Storage: Sensitive data (user ID, credit balance, subscription status) is stored in the iOS Keychain, which provides hardware-level encryption.
• App Storage: Cached images, generation history thumbnails, AI chat conversation history, and app preferences are stored locally within the app sandbox on your device.
• Chat Messages: AI chat conversation history is stored only on your device and is not transmitted to or stored on our servers.

Data Retention

Your data is retained for as long as your account is active. You may delete individual generation history items at any time through the app. You may delete your entire account through the app's settings, which will remove your profile data and generation history from our servers. Locally cached data is removed when you uninstall the app.

5. Third-Party Services

We use the following categories of third-party services to operate the app:

• Google Firebase: Anonymous authentication, Cloud Firestore database, and Cloud Storage for files. Firebase processes your anonymous account data, profile information, and stored generation results. Firebase Privacy Information
• Apple StoreKit: Processes all In-App Purchases and subscription transactions. Apple handles all payment processing. Apple Privacy Policy
• AI Generation Providers: Third-party AI services process your uploaded images and text prompts to generate tattoo previews, images, videos, and chat responses. These providers receive only the content necessary to perform the generation and are contractually required to process data solely for the purpose of delivering results.
• Cloudflare: Hosts our backend API infrastructure and provides security, rate limiting, and DDoS protection. Cloudflare Privacy Policy
• Apple Speech Recognition: Voice input is processed on-device using Apple's Speech framework. Audio data is handled by Apple's on-device speech recognition and is subject to Apple's Privacy Policy.

6. Data Sharing and Disclosure
