This Privacy Policy describes how IE Denis Zhesterev ("we," "us," or "our") collects, uses, and protects information when you use our mobile application Hf (the "App"). By using the App, you agree to the collection and use of information in accordance with this Privacy Policy.
1.1 User-Provided Content: When you use Hf, you upload videos, images, and audio for AI-powered processing. This content includes visual data, audio data, and any faces depicted therein.
1.2 Device Identifier: We use your device's unique identifier (UUID) to identify your account and associate your content, purchases, and token balance with your device. This identifier is essential for the App's functionality.
1.3 Token and Transaction Data: We collect and store information about your virtual currency (tokens), including:
1.4 Analytics Data: We collect anonymized usage analytics through third-party services to improve the App. This includes:
1.5 Information We Do NOT Collect: We do not collect email addresses, phone numbers, names, physical addresses, or any personal information unless you voluntarily provide it when contacting us for support.
2.1 AI Service Providers: We use the following third-party AI providers to process your content:
2.2 Purpose of Data Sharing: Your content is shared with these AI providers solely to generate the AI-processed output you requested. This includes face-swapping in videos, image generation, and voice conversion.
2.3 Data Retention by AI Providers: Our AI providers process your content in real-time and do not retain your images, videos, or audio after processing is complete. Please refer to their respective privacy policies:
2.4 Data Protection Standards: We require that all third-party AI service providers who receive your data maintain data protection and privacy standards that are the same as or equivalent to those described in this Privacy Policy. Our agreements with these providers include obligations to process your data securely, use it only for the purposes described herein, and delete it promptly after processing is complete.
2.5 Your Consent: Before your content is processed by third-party AI services, you will be asked to provide explicit consent within the App. The consent prompt will clearly identify what data is being sent, who it is sent to, and for what purpose. You may decline, but this will prevent you from using the AI-powered features.
3.1 Payment Processing: All payments for subscriptions and token packages are processed through the Apple App Store and managed by RevenueCat, Inc. We do not directly collect or store your payment card information.
3.2 RevenueCat: We use RevenueCat (revenuecat.com) to manage subscriptions and in-app purchases. RevenueCat receives and processes:

3.3 Token Balance Storage: Your token balance and transaction history are stored on our servers and linked to your device identifier. This data is necessary to provide the token-based service functionality.
4.1 Processing Flow: When you upload content: (1) Your video, image, or audio is uploaded to our servers hosted by Hetzner in Germany (EU); (2) We transmit your content to our AI providers (Fal.ai or ElevenLabs) for processing; (3) The AI-generated result is returned and stored on our servers; (4) You can view and download your results within the App.
4.2 Storage Duration:
4.3 No Biometric Data Storage: We do not extract, store, or create biometric identifiers, facial recognition templates, or facial geometry data from your content. Face-swapping is performed by AI in real-time without creating persistent facial data. For comprehensive details on how we handle face data, see Section 5.
5.1 Definition of Face Data: "Face data" refers to any photographs, images, or video content you upload to the App that contains human faces, as well as any AI-processed output (face-swapped videos and images) that depicts human faces.
5.2 No Biometric Data or Facial Recognition: We do not extract, store, or create biometric identifiers, facial recognition templates, faceprints, or facial geometry maps from your face data. We do not use face data for facial recognition or identification purposes. Face-swapping is performed entirely by our third-party AI provider in real-time without creating persistent biometric profiles.
5.3 Face Data Is Not Retained Indefinitely: We do not retain face data indefinitely. All face data is subject to strict retention periods and is permanently deleted thereafter:
5.4 Third-Party Sharing of Face Data: Face data is shared exclusively with the following third-party AI provider for processing:
We do not share face data with any other third parties. Our other service providers (ElevenLabs, RevenueCat, Amplitude, AppsFlyer) do not receive face data.
5.5 Reason for Sharing Face Data with Third Parties: We share face data with Fal.ai solely because the AI-powered face-swapping processing is performed by their service. Without transmitting your face data to Fal.ai, the core functionality of the App — replacing faces in videos and generating face-swapped images — cannot be provided.
5.6 Third-Party Face Data Storage Practices: Fal.ai does not store your face data after processing is complete. Your face data is processed in real-time and is immediately discarded by Fal.ai upon completion of the processing request. Fal.ai does not use your face data to train AI models. For full details on their data handling practices, please refer to the Fal.ai Privacy Policy.
5.7 No Sale of Face Data: We do not sell, license, rent, or otherwise monetize your face data in any way. Face data is used exclusively to provide you with the face-swapping service you requested.
