This Privacy Policy applies exclusively to the Sorvin mobile application, a lightweight iOS tool for one-click short video generation from single photos. This policy clearly explains how we handle all user data when you use our App, clarifies our data storage rules, data transmission rules and user privacy protection measures. Sorvin requires no user account registration, login, mobile phone number binding or email binding for all core functions, and we attach top priority to protecting every user's personal privacy throughout the use process. The App does not collect any facial recognition information from users under any circumstances, and we will never share any of users' personal data with any third-party AI service providers for any purpose.
This privacy policy covers all behaviors and data interactions when users download, install, open, operate and uninstall the Sorvin App on iOS devices. We promise that all video generation, picture processing and text matching operations run completely locally on users' mobile devices, without any remote data uploading triggered by the App background program. The App does not collect any facial recognition information from users under any circumstances, and we will never share any of users' personal data with any third-party AI service providers for any purpose. We have no intention to obtain, analyze or utilize any user privacy information beyond local device operation logs, and all user-generated content is completely controlled by users themselves.
To fully protect user privacy, we have designed the App with a zero-active-data-collection framework. We clearly list all data categories that we will never collect as follows, and this rule takes effect permanently during the entire use cycle of the App:
Users can upload single local photos and add custom text descriptions to generate short videos via the App. All processing and storage rules for these user content are stipulated as below:
Sorvin adopts a fully independent local operation architecture, and the App does not access any third-party cloud service, third-party image processing service, third-party video synthesis service or third-party AI algorithm service in all functional links including picture upload, text matching, video editing, transition production and subtitle generation. The App does not collect any facial recognition information from users in all third-party service connection links, and we will never share any of users' personal data, uploaded pictures, text content and generated video works with any third-party AI service providers for any commercial or non-commercial purpose.
Besides third-party AI services, we also promise that we will never sell, rent, trade or disclose user private data to any other third-party companies, organizations or individual users. The only external data transmission behavior of the App is the official iOS system built-in sharing function (sharing videos to social platforms selected by users actively). This sharing behavior is completely initiated and operated by users independently, and the App will not automatically share any user content without user authorization. The App does not collect any facial recognition information from users during user-initiated social sharing, and we will never take the initiative to transmit user sharing data to any third-party AI service providers.
Sorvin only applies for two necessary iOS system permissions to realize core creation functions, and we will never apply for redundant device permissions that involve user privacy:
The App never applies for camera permission, microphone permission, location permission, contact permission and other sensitive permissions, so there is no channel to obtain user facial information and other sensitive privacy content. The App does not collect any facial recognition information from users due to no camera permission access, and we will never share any permission-related user data with any third-party AI service providers for any purpose.
Although all user data is stored locally without remote transmission, we still build multiple local security protection mechanisms to prevent accidental leakage of user local content: the App adopts local data encryption for temporary cached creation files; the App will not synchronize local creation content to iCloud or other cloud disks automatically; all temporary cache files will be automatically cleared after users exit the App completely. The App does not collect any facial recognition information from users during local data security protection, and we will never share any encrypted local user data with any third-party AI service providers for any purpose.
All photos uploaded by users, custom text descriptions input by users, and all short videos generated by the App belong to exclusive intellectual property of users. Our team does not obtain any use rights, reproduction rights, editing rights or distribution rights of user created content. We will not use user created content for internal product optimization, commercial promotion, model training or other scenarios. The App does not collect any facial recognition information contained in user created content, and we will never use user created content to provide data support for any third-party AI service providers, nor share relevant content with third-party AI platforms.
We have the right to update and revise this Privacy Policy irregularly to match App function iteration and iOS official platform specification adjustments. Once the policy is updated, we will publish the latest version inside the App and update the last updated date synchronously. Continued use of the Sorvin App after policy update means that you agree to the revised privacy policy content. No matter how the policy is updated, we will always adhere to the core principle: the App does not collect any facial recognition information from users under any circumstances, and we will never share any of users' personal data with any third-party AI service providers for any purpose.
