Privacy Policy

1. Introduction

Nostal is a local creative studio application dedicated to retro portrait creation and visual content generation. This privacy policy outlines the local data processing practices of our application, explaining how local user information is managed, stored, and maintained within the user's personal device. Nostal is designed for offline and local device use, focusing on protecting every user's personal content and visual creation data throughout the entire usage process.

All information is processed locally, all information is only stored on the user's local device, the information will be permanently deleted once the user actively deletes the content or data in the application, and Nostal does not collect any facial data from users in any form or scenario.

This local processing rule applies to all user behaviors and creation operations within the application, and no user facial information will be acquired or retained in any way during the full usage cycle.

2. Local Data Processing And Storage Rules

2.1 Local Operation Mechanism

All functional operations of Nostal run completely on the user's local device. All AI rendering, scene creation, portrait generation, and content editing processes are completed through local device computing resources, without any remote data transmission. The application only processes data locally on the user's device, retains all generated content and user operation records locally, and does not collect any facial data from users at any stage of operation.

2.2 Local Data Retention And Deletion

All user creation works, draft records, motion clips, and local folio content are exclusively stored in the local storage space of the user's device. The application will not automatically retain or back up any user data. All data exists only in the user's local device, and all related data will be completely removed after active deletion by the user, with no facial data collected or stored by the application.

2.3 No Account Registration Requirement

Nostal allows all users to access and use all core functions without any account registration or login process. There is no need for users to submit any personal identity information or biometric information during usage. Since no user identity verification is required, the application cannot and does not collect any facial data or other biometric information from users.

3. User Generated Content Protection

3.1 Local Content Ownership

All retro portrait stills, motion clips, and creative content generated by users through Nostal belong entirely to the user. All content generation processes are completed locally on the user's device. The application only renders content based on local user input instructions, does not collect any facial data involved in user creation scenarios, and does not obtain any user facial information.

3.2 Local Content Management

Users have full independent management rights for all local content in the application. Users can freely save, preview, delete, and organize local creative works and folio files. All content changes only take effect on the user's local device. No local content or user facial data will be acquired by the application, and all user operation behaviors are limited to local device processing without any external data interaction.

4. Application Function Privacy Specifications

4.1 Text Rendering Function Privacy

The core text rendering function of Nostal completes scene generation and portrait creation through local device algorithm calculation. All scene brief input, mood selection, and rendering operations are executed locally. The local AI rendering process only responds to user text instructions, does not scan, identify, or collect any user facial data, and no facial information will be generated or stored in the process.

4.2 Motion Clip Production Privacy

The function of converting local stills to motion clips is completed through local device computing. All camera path matching and narrative branch selection operations are processed locally. The entire motion production process is limited to local device operation, does not collect any user facial data, and will not extract any biometric information from user local works.

4.3 Local Folio Management Privacy

The local folio function classifies and stores user creative works only inside the user's device. There is no cloud gallery, public upload channel, or social content sharing platform inside the application. All folio content is stored locally, the application does not collect any user facial data, and no local content or user biometric information will be transmitted outward.

5. In-app Purchase Privacy Rules

All in-app purchase behaviors including reel token packs and patina membership subscriptions are completed through the official app store payment system. The application only records local purchase status on the user's device to unlock corresponding functional permissions. The processing of local purchase data does not involve any user facial data collection, and no facial information is associated with user purchase records.

6. Local Privacy Security Guarantee

Nostal adheres to the core principle of full local data processing. All user operation data, creative content, and functional usage records are confined to the user's personal device. Users can completely control all local data access and deletion rights. The application fundamentally does not collect, store, or obtain any user facial data, and all data processing behaviors are limited to local device independent operation.
