This Privacy Policy clearly explains how the Nerlia application handles user photos, video content, device data, and user privacy protection rules. This policy applies to all users of the Nerlia app, covering all core functions including doll portrait creation, animated video generation, local gallery management, and system setting operations. Nerlia adheres to the core principle of local on-device processing and user data autonomy, focusing on protecting every user’s content privacy and personal device data security.
Nerlia is a lightweight doll portrait and short video creation application that does not require user registration, account login, or identity authentication. All application functions can be used directly after users install and authorize basic device permissions. We have always taken local data security and zero sensitive data collection as our core operating principles.
The most critical privacy rule of Nerlia is that we absolutely do not collect, store, upload, or utilize any user facial information and facial biometric data in any form. All facial-related image and video processing operations are completely completed locally on the user’s personal device during real-time use. The app will not capture facial feature points, facial contour data, facial biometric templates, facial recognition information, or any derivative facial data. No facial data will be transmitted to any external server, cloud platform, or third-party institution. No facial data will be cached, reserved, or backed up in any background program of the application. After the user exits the editing interface or closes the app, all temporary facial calculation data generated during processing will be automatically cleared from the device memory without any residual retention.
Nerlia does not build any user account system, and there is no registration, login, binding, or identity verification function in the whole app. Users do not need to provide any personal identity information such as name, nickname, mobile phone number, email address, or social account information when using all creation, preview, saving, and sharing functions.
Since there is no account system and no user identity association mechanism, the app has no channel to bind, record, or collect user facial information. All doll portrait and animated video creation behaviors are completely independent local operations on the user device. The app cannot associate facial content with any user individual, cannot extract facial feature data for user identification, and cannot store or upload any facial information of users. There is no facial data collection behavior in the whole process of identity verification and function use.
All core creation functions of Nerlia, including doll portrait synthesis and animated video clip generation, adopt full on-device local processing technology. Users can take photos through the device camera or select portrait photos from the local photo library for creation, and all AI algorithm calculation, doll template fitting, picture angle adaptation, light and shadow adjustment, and video dynamic rendering are completed inside the user’s mobile device without any network data transmission.
During the local processing of photos and videos, Nerlia only performs visual layer fitting and color light adjustment on the user’s portrait content based on preset doll templates. The app will not analyze, extract, or record any facial feature information of users. It will not collect facial contour data, eye and nose feature parameters, facial skin texture information, facial expression data, or any other facial biometric information. The AI model only completes picture synthesis and dynamic rendering based on image pixel presentation, and does not generate, store or upload any facial feature recognition data. All portrait content only exists in the user’s local device storage space, and the developer cannot obtain any user facial information in any way.
All user creation works, including finished doll portraits and short animated videos, are uniformly stored in the local gallery of the Nerlia app, and all data files are only retained on the user’s personal device. Users can independently:
When the user actively deletes any work, the corresponding content files and temporary data will be completely and permanently removed from the local device without any background retention or hidden backup.
In the whole process of local storage and content management, Nerlia never collects or retains user facial information. The local storage module only stores the integrated picture and video files formed by the combination of user portraits and doll templates, and does not separately split, extract or store user facial data. The deleted content will completely eliminate all local file information, including all temporary facial pixel calculation data generated during creation. The developer has no access authority to obtain, restore or collect any user facial information, and there is no facial data storage or collection behavior throughout the whole process.
Nerlia only applies for the most basic device permissions required for normal operation, including camera permission and photo library access permission. The camera permission is only used for users to take real-time portrait photos for doll creation, and the photo library permission is only used for users to select local portrait photos and save finished works. All permissions are used only for user independent creation operations, without any background monitoring, automatic scanning or data uploading behavior.
The acquisition of camera and photo library permissions by Nerlia is only for the user’s active photo shooting and material selection operations. The app will not actively scan, monitor or collect user facial information in the background. It will not automatically capture user facial images, record facial dynamic information, or analyze facial feature data. All permission calls are triggered by the user’s active operation, and no facial data is collected, recorded or uploaded during permission use. The permission system does not reserve any facial data acquisition interface, fundamentally avoiding any possibility of facial information collection.
The Nerlia setting module provides an independent cache cleaning function, which allows users to independently clear application generation cache and temporary resource files. All cached data is only local temporary resource data generated by template loading and picture rendering, without any user personal sensitive information and portrait feature data. Users can completely clear all local cache data at any time to ensure the privacy and security of device content.
All cached data generated during the operation of Nerlia does not contain any user facial information, facial biometric features or facial recognition data. The cached content is only public doll template resources, picture rendering parameter records and program running temporary files, and does not involve any user personal portrait feature information. The app will not secretly retain facial data in the form of cache files, will not back up facial information through cache channels, and all cache cleaning operations can completely eliminate all temporary data generated by the app, ensuring that no user facial information is retained locally or collected by the developer.
Nerlia does not access any third-party statistical tools, third-party tracking SDKs, advertising service platforms or cloud service platforms. The app does not share, transmit or authorize any third-party institutions or individuals to obtain user device data, creation content and operation records. There is no data sharing, data leasing or data trading behavior in the whole application operation process.
Since Nerlia has no third-party data interaction channels, there is no possibility of user facial information being collected or leaked through third-party channels. The app itself does not actively collect any facial data, and does not transmit any user portrait and facial related information to third-party platforms. No third-party institution can obtain, analyze or utilize user facial information through the Nerlia app. The whole process realizes zero collection and zero sharing of user facial data.
Nerlia is a universal casual creation application suitable for all user groups. The app does not set any age restriction mechanism, does not distinguish user age groups, and does not collect, verify or record user age information. All users can freely download, install and use all core functions of the app without age-based function restriction or authority distinction.
