Privacy Policy
Last updated: June 11, 2026
App Name: Aura Z
Developer: Kyun Labs
This Privacy Policy explains how Kyun Labs (“we,” “us,” or “our”) collects, uses, and protects your information when you use our AI-powered beauty application, Aura Z.
1. Information We Collect
We believe in data minimization. We only collect the data necessary to provide the service, deliver personalized beauty insights, and ensure app stability.
A. Authentication & Account Data
- Anonymous Access (Default): When you first use the app, we create an anonymous account via Firebase to store your data without requiring personal details such as your name or email address.
- Referral Codes: If you participate in our referral program, a unique referral code is generated and associated with your anonymous account.
B. Biometric & Facial Data
- Selfies & Photos: When you use our face analysis, glow-up transformation, or hairstyle features, you provide photos of your face. These images are processed by AI to generate beauty scores, analyses, and transformed images.
- Facial Analysis Results: We store the results of your facial analyses, including beauty scores, feature-level assessments, and improvement suggestions.
- Progress Photos: If you use the progress tracking feature, we store dated photos and corresponding scores to show your beauty journey over time.
- Important: We do not use facial recognition technology to identify you. Facial data is used solely for the purpose of providing beauty analysis and transformation features within the app.
C. AI Conversations
- Bella Chat History: Conversations with our AI beauty assistant, Bella, are stored to provide contextual and personalized responses within your current and future sessions.
D. User-Generated Content & Cloud Storage
- Generated Images: AI-generated glow-up transformations, hairstyle previews, and other image outputs are stored in our cloud storage infrastructure (Cloudflare R2) and associated with your anonymous account.
- Routine Data: Skincare routines you follow, daily completion logs, streak data, and achievement progress are stored to deliver the routine and gamification features of the app.
E. Transaction & Economy Data
- Coin Balances & Transactions: We record your Coin balance, purchase history, earned rewards, referral redemptions, and feature spend to maintain your in-app economy.
- Subscription Status: We record whether you have an active subscription, its type, and billing cycle to provide access to premium features. Payment processing is handled by Apple or Google; we do not store credit card or payment method details.
F. Automated Data Collection
- Device Data: We collect device model, OS version, locale, app version, and IP address to troubleshoot bugs, ensure app security, and comply with regional pricing.
- Usage Analytics: We collect anonymized usage data such as feature usage frequency, onboarding completion, and session length to improve the Service.
- Attribution Data: We use third-party attribution tools (AppsFlyer) to understand how users discover and install the app. This data is used for marketing analytics and does not include the content of your photos or conversations.
- Crash Reports: We use Firebase Crashlytics to collect crash logs and error reports to maintain app stability.
2. How We Use Your Information
We use the collected information for the following purposes:
- Service Provision: To deliver facial analyses, generate beauty scores, create AI transformations, provide skincare routines, power the Bella AI assistant, manage your Coin economy, and track your progress.
- Personalization: To tailor recommendations, routines, and AI responses based on your skin type, facial features, and usage patterns.
- Analytics & Improvements: To understand how users interact with the app so we can improve features, optimize the user experience, and develop new functionality.
- Fraud Prevention: To detect and prevent abuse of the Coin economy, referral system, and other features.
3. Data Processing & Infrastructure
When you use the app, your data is transmitted securely to our cloud infrastructure providers:
- Firebase / Google Cloud: Authentication, database (Firestore), cloud functions, remote configuration, and crash reporting.
- Cloudflare R2: Storage of AI-generated images and user-uploaded photos.
- Google Gemini API / WaveSpeed API: Processing of your face photos for AI facial analysis and image generation (glow-up and hairstyle transformations). Your photo is transmitted to these providers only at the moment a feature is used, solely to return the requested result.
- DeepSeek API: Powering the Bella AI assistant. Bella receives only the text of your conversation — your face photos are never sent to DeepSeek.
- AppsFlyer: Attribution and marketing analytics.
- RevenueCat: Subscription and purchase management.
We use industry-standard encryption (TLS) to protect your data in transit and at rest.
4. AI Data Processing
Aura Z uses artificial intelligence extensively. You should understand how your data interacts with AI systems:
- Photo Processing:When you submit a photo for analysis or transformation, the image is sent to Google’s Gemini API or WaveSpeed API for processing. We send only the data necessary for the specific feature you are using.
- AI Conversations: Messages you send to Bella are processed by AI services to generate responses. Conversation context is maintained to improve response quality.
- No AI Training by Kyun Labs: Kyun Labs does not use your personal photos, facial data, or conversation content to train our own AI models.
- Third-Party AI Providers:We require every third party with whom we share your data — including our AI providers (Google’s Gemini API, WaveSpeed, and DeepSeek) and our infrastructure providers — to provide the same or an equivalent level of protection for your data as described in this Privacy Policy and as required by applicable law. These providers may also maintain their own data processing policies, and we encourage you to review their respective privacy policies.
5. Cookies, Analytics & Advertising
We use local storage technologies and third-party tools to maintain your session and support our business.
- Essential: Tokens and identifiers required to keep you logged in, sync your data, and manage your subscription status.
- Analytics: We use analytics tools (Firebase Analytics, Crashlytics) to understand app performance, feature usage, and crash reports.
- Attribution:We use AppsFlyer to measure the effectiveness of our marketing campaigns. This may involve collecting your device’s advertising identifier (IDFA/GAID) subject to your consent where required by platform policies (e.g., Apple’s App Tracking Transparency).
6. Data Sharing & Business Transfers
We do not sell your personal information, photos, or facial data. However, we share data in these strictly necessary scenarios:
- Service Providers:With our secure cloud hosting and AI processing partners solely to facilitate the app’s core functions as described in Section 3.
- Legal Compliance: We may disclose information if required by a valid legal request, court order, or governmental regulation.
- Business Transfers: If Kyun Labs undergoes a merger, acquisition, bankruptcy, or sale of assets, your data may be transferred to the successor entity. We will notify users of any such transfer and any changes to this Privacy Policy.
- Aggregated & Anonymized Data: We may share aggregated, non-identifiable statistics (e.g., total number of analyses performed, average scores by region) for business or research purposes.
7. Data Retention
- Active Accounts: We retain your data for as long as your account is active and as needed to provide you with the Service.
- Deleted Accounts: When you delete your account, all personal data, photos, generated images, analysis results, conversation history, Coin balances, and progress data are permanently removed from our active databases within 30 days. Backup copies may persist for up to 90 days before being permanently purged.
- AI-Generated Images: Images stored in Cloudflare R2 are deleted when you delete your account or when you manually delete specific generated content within the app.
