We take data security and privacy very seriously. All operations of this tool are performed locally in your browser. Your JSON files and API keys are never uploaded to our servers. This ensures that your data privacy and business secrets are absolutely safe. Specifically, the entire process works as follows: 1. Local Processing: When you upload a JSON file, it is loaded directly into your browser's memory. It does not pass through any remote server. 2. API Key Security: Your API Key is stored only in the browser's temporary session. It is directly sent from your browser to the AI provider's official API endpoint (e.g., OpenAI, Google Gemini) for translation, without going through our server as a proxy. 3. No Data Retention: Once you close the browser tab, all data, including the file content and API Key, is immediately cleared. We do not store, record, or analyze any of your operational data. You can use this tool with complete confidence, as your sensitive information never leaves your own computer.

We use AI models for translation to ensure the accuracy of professional terminology and the naturalness of language expression. We also support custom dictionary functions to maintain the consistency of specific terms.

The maximum size for a single JSON file is 10MB. For larger files, it is recommended to translate them in batches.
