We are Lai Qiao(赖巧), doing business as ChatTranslate ("Company," "we," "us," "our"), a company registered in China at Building 3, 3rd Floor, Room 405, Longling Incubation Base, Yuancheng District, Heyuan, Guangdong 517000.
We operate the website https://zengfeiyue.github.io (the "Site"), the mobile application ChatTranslate (the "App"), as well as any other related products and services that refer or link to these legal terms (the "Legal Terms") (collectively, the "Services").
Welcome to ChatTranslate! We provide an offline-first voice translation and transcription application. Speech recognition, translation, and optical character recognition (OCR) run locally on your device so you can translate speech and text without sending your audio or content to our servers.
You can contact us by email at quaintlq@icloud.com or by mail to Building 3, 3rd Floor, Room 405, Longling Incubation Base, Yuancheng District, Heyuan, Guangdong 517000, China.
These Legal Terms constitute a legally binding agreement made between you, whether personally or on behalf of an entity ("you"), and Lai Qiao(赖巧), concerning your access to and use of the Services. You agree that by accessing the Services, you have read, understood, and agreed to be bound by all of these Legal Terms. IF YOU DO NOT AGREE WITH ALL OF THESE LEGAL TERMS, THEN YOU ARE EXPRESSLY PROHIBITED FROM USING THE SERVICES AND YOU MUST DISCONTINUE USE IMMEDIATELY.
We will notify you about updates to our legal terms by sending an email notification and/or by posting a notice within our application.
The Services are intended for users who are at least 18 years old. Persons under the age of 18 are not permitted to use or register for the Services.
We recommend that you print a copy of these Legal Terms for your records.
The information provided when using the Services is not intended for distribution to or use by any person or entity in any jurisdiction or country where such distribution or use would be contrary to law or regulation or which would subject us to any registration requirement within such jurisdiction or country. Accordingly, those persons who choose to access the Services from other locations do so on their own initiative and are solely responsible for compliance with local laws, if and to the extent local laws are applicable.
The Services are not tailored to comply with industry-specific regulations (Health Insurance Portability and Accountability Act (HIPAA), Federal Information Security Management Act (FISMA), etc.), so if your interactions would be subjected to such laws, you may not use the Services. You may not use the Services in a way that would violate the Gramm-Leach-Bliley Act (GLBA).
On-Device and Cloud Processing: ChatTranslate is designed to perform speech recognition and translation / OCR locally on your device by default (via Apple Speech, Google on-device, Vosk, Whisper/sherpa-onnx, Qwen3-ASR, Apple Translation, ML Kit, Gemma, Hunyuan Hy-MT2, or ML Kit OCR). Your spoken audio and the text you translate are processed on-device and are not uploaded to our servers when you use on-device features. The App also offers optional cloud speech recognition and translation powered by third-party providers (Google Cloud, Tencent Cloud, Alibaba Cloud); when you use a cloud feature, your audio and/or text is sent to the selected provider. Machine-learning model files are bundled within the App or downloaded on demand. Translation quality depends on the models and the capabilities of your device, and results may vary. We do not guarantee the accuracy, completeness, or fitness for any particular purpose of any transcription or translation produced by the Services.
We are the owner or the licensee of all intellectual property rights in our Services, including all source code, databases, functionality, software, website designs, audio, video, text, photographs, and graphics in the Services (collectively, the "Content"), as well as the trademarks, service marks, and logos contained therein (the "Marks").
