Đẹp Tướng – Privacy Policy

This app is developed by Hohama Studio and uses AI to process user-provided face images and birth information to deliver personalized suggestions. Your privacy is important to us. This Privacy Policy explains what data we collect, how we handle it, when we send it to third-party AI services, and how you can control your data.

Information We Collect
We may collect the following data when you use the App:

  • Personal identifiers
  • Email (if provided)
  • Device ID and IP address
  • Advertising identifiers (IDFA/GAID), subject to your device settings and, on iOS, App Tracking Transparency (ATT) consent.
  • Profile & birth data
  • Name or nickname (if provided)
  • Date of birth, time of birth (if provided)
  • Gender (if provided)
  • Usage data
  • App interactions, screens viewed, feature usage
  • In-app events related to AI analysis, subscriptions, and settings
  • Technical logs from third‑party services (e.g., Firebase, Adjust) to help us monitor performance, stability, and attribution.
  • Payment data
  • Subscription or in-app purchase details (handled primarily by the App Store / Google Play).
  • We do not receive your full payment card number. We may receive non-sensitive transaction metadata (e.g., product ID, price, country) for accounting and analytics.

Face Data & Input to AI (Special Category)
We collect and temporarily store face images that you upload in order to generate AI-based insights and personalized suggestions. In some features, we also combine your face image with your birth data and gender as inputs to AI models.

  • What is sent to AI models
    Depending on the feature you use, the following data may be sent to our backend and then processed by third‑party AI services:
  • Face image you upload (selfie or portrait you choose).
  • Derived image data, such as facial landmarks or cropped face regions.
  • Birth information: date of birth, time of birth (if provided).
  • Gender (if provided).
  • A user identifier (e.g., anonymized user ID) to link results to your account.
  • Purpose
  • Face images and birth data are used solely to:
  • Analyze facial features in a non‑biometric way (no identity/face matching).
  • Generate self‑reflection content, astrological or personality-style interpretations, and beauty/“feng shui” style suggestions.
  • They are not used for biometric identification, authentication, or any form of surveillance.
  • Storage
  • Face images are securely stored in Google Cloud Storage, which acts only as our cloud infrastructure provider.
  • Google Cloud does not access or use this data for its own purposes beyond providing storage and computing.
  • Retention
  • Uploaded face images are stored for up to 365 days to allow you ongoing access to your image history and analysis results.
  • Birth data and gender, if provided, may also be stored as part of your profile and analysis history.
  • After 365 days, face images are automatically deleted unless you delete them earlier yourself.
  • You may request deletion of your profile and related data at any time (see “Your Rights” below).
  • Sharing
  • We do not sell or rent your face data.
  • We do not use face data for advertising or ad targeting.
  • Face data and related inputs (e.g., birth date, gender) are shared only with:
  • Our own backend servers, and
  • Third‑party AI processing providers listed in the “Third‑Party Services and AI Providers” section, solely for the purpose of generating analysis results.
  • User Control
  • You can permanently delete your stored face data at any time via in‑app controls (where available) or by contacting us at support@hohama.com.
  • You may also choose to not use AI-based features at all. In that case, we do not send your face images or birth information to third‑party AI services.

How We Use Your Data
We use the collected data to:

  • Process and generate AI-based insights and suggestions about:
  • Facial features (non‑biometric), aesthetics, and style ideas.
  • Personality-style or astrological interpretations based on your birth data and gender.
  • Provide, maintain, and improve the App’s functionality and user experience.
  • Personalize certain non‑advertising content within the app (e.g., recommendations of which features to try).
  • Analyze usage and performance for bug fixes, optimization, and product improvements.
  • Handle subscriptions and payments (together with the App Store / Google Play).
  • Comply with legal obligations, enforce our terms, and prevent abuse.
    This App is for informational and self-reflection purposes only. It does not provide medical, psychological, legal, or financial advice.

Data Retention

  • Uploaded face images are stored for up to 365 days to allow you ongoing access to your image history and analysis results.
  • Birth data and gender may be stored for as long as your account is active to allow the app to re-use your profile in future analyses.
  • This retention period is chosen to provide convenience while respecting user privacy.
  • You may request earlier deletion at any time; after 365 days, face images are automatically deleted unless you delete them sooner.

Third‑Party Services and AI Providers
We rely on trusted third‑party services to operate and improve the App:

  • Google Firebase (Analytics, Crash Reporting, Authentication)
  • Used for app analytics, stability monitoring, authentication, and backend infrastructure.
  • May receive technical and usage data (e.g., device information, approximate location, feature usage, crash logs).
  • Adjust (App Install Attribution & Campaign Measurement)
  • Used to understand where users discover the app and to measure the performance of marketing campaigns.
  • May receive advertising identifiers and basic event data, subject to your device settings and iOS App Tracking Transparency (ATT) consent.
  • Cloud-Based AI Services
  • We use cloud AI providers (such as Google Cloud / Google AI (Gemini) or similar services) to:
  • Process your uploaded face images, and
  • Process your birth data and gender (if provided),
  • Generate AI-based analysis texts, summaries, and suggestions.
  • These AI providers act as our data processors. They process your data under our instructions and are contractually required to provide equal or stronger privacy protection and security controls.
  • They do not use your data for their own advertising or for training models in a way that identifies you, outside the scope of providing services to us (subject to their platform settings and our configuration).
  • Customer Support & Notifications (e.g., Zendesk, Twilio – if used)
  • Used to provide user support and send transactional notifications (such as subscription confirmations or important service announcements).
    These services may access limited technical or content data as needed to provide their functions, but they do not retain or use your face images and personal content beyond what is required to deliver the requested analysis and app functionality.

AI Processing & User Consent
Because some features use your face image together with birth data and gender and send them to third‑party AI services, we implement additional consent and transparency steps:

  • In‑app AI consent dialog
  • Before we send your face image, birth data, gender, and user identifier to our backend and third‑party AI providers, the app shows a clear consent message that:
  • Explains what data will be sent (face image, birth information, gender, user ID).
  • Explains who will receive the data (our servers and cloud AI providers such as Google Cloud / Google AI).
  • Asks whether you agree to this processing.
  • If you do not agree, the app will:
  • Not call the AI endpoints for that feature.
  • Not send your face image and birth data to third‑party AI services for that analysis.
  • Opt-out of AI features
  • You can choose not to use AI-based analysis features at any time. In that case, your data is not sent to third‑party AI models for these purposes.
  • Privacy policy alignment
  • This Privacy Policy describes what data is collected, how it is used, and which third‑party AI providers are involved.
  • We require any third‑party AI provider we use to provide at least the same level of protection for your data as described here.

App Tracking Transparency (iOS)
On iOS and iPadOS, we comply with Apple’s App Tracking Transparency (ATT) framework:

  • We may request permission to access your advertising identifier (IDFA) to measure the performance of marketing campaigns via Adjust or similar tools.
  • The ATT prompt clearly explains that:
  • The identifier may be used for advertising measurement and to improve marketing effectiveness.
  • You can choose “Allow” or “Ask App Not to Track”:
  • If you decline, we respect your choice and:
  • Do not access the IDFA.
  • Limit tracking and attribution in accordance with Apple’s guidelines.
  • You can change this decision at any time in your device’s Settings > Privacy & Security > Tracking.
    This tracking permission is separate from consent for AI processing of your face image and birth data.

Data Security
We implement standard security measures to protect your data, including:

  • Encryption in transit (HTTPS) and secure storage.
  • Access controls on our servers and cloud infrastructure.
  • Regular monitoring for suspicious activity.
    However, no method of transmission over the Internet or method of electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your personal data, we cannot guarantee absolute security.

Children’s Privacy
This App is not intended for persons under 13. We do not knowingly collect personal data from children under 13.If we become aware that we have collected data from a child under 13, we will take steps to delete such data as soon as possible.
