林深是 AI
极客林深（Lin）是 dfmi 团队运营的 AI 工程师，帮你看懂开源代码、排查技术问题，也整理财经公开信息。画面里的人物形象、声音和每一条回答都由人工智能生成，不是真人实时出镜。回答可能有误，仅供参考；财经内容是公开信息整理，不构成投资建议。林深会介绍我们自己的产品 dfmi。
我们会处理哪些信息
- 你的提问和林深的回答：用来生成回答、改进林深。会记录在服务器日志里（问题、回答、用了哪些工具、耗时和花费），保存 90 天后自动删除。
- 你的评价：👍 / 👎 和你选的原因，和上面一样保存 90 天。
- 语音提问：只在你按下麦克风按钮后录音。录音会发给 OpenAI 转成文字，转完即用，我们不保存录音。
- 林深学到的知识：林深查资料后会记下公开来源里的要点（不是你的个人信息），有时会附上当时的问题，最长保存 180 天。
- 网络信息：你的 IP 地址用于防滥用（限制每人提问次数），只在内存里短暂保留；网站服务器的访问日志按常规轮转删除。
- Cookie 和本地存储：只用来记住你已登录（30 天）、你选的语言等设置，不做广告跟踪。
请不要在提问里写身份证号、密码、API 密钥、私钥、助记词等敏感信息，贴代码或报错时也请先删掉这些内容。
交给哪些服务商
- Anthropic（Claude）：生成回答，也用于网页搜索。
- Cognition（DeepWiki）：查询 GitHub 公开仓库的代码和文档，代码相关的问题会发给它。
- Ollama：打招呼、闲聊这类简单对话由它的模型回答。
- OpenAI：把回答合成为林深的声音；把语音提问转成文字。
- Amazon Web Services：服务器托管（美国）。
这些服务商按各自的隐私政策处理数据，我们只把回答问题所需的内容发给它们。数据可能在美国处理。
你的选择
- 不想被录音，就只打字提问，不用麦克风。
- 想删除你的提问记录，可以通过 dfmi.app 上的联系方式告诉我们大概的时间和内容。

Lin is an AI
Lin (极客林深) is an AI engineer run by the dfmi team. He helps you understand open-source code and troubleshoot technical problems, and also summarizes public finance information. His appearance, voice and every answer are generated by AI — he is not a real person on camera. Answers may contain errors and are for reference only; finance content is public information, not investment advice. Lin talks about our own product, dfmi.
What we process
- Your questions and Lin's answers: used to answer you and to improve Lin. They are kept in server logs (question, answer, tools used, time and cost) and deleted after 90 days.
- Your ratings: 👍 / 👎 and the reason you pick, also kept for 90 days.
- Voice questions: recorded only after you press the microphone button. The recording is sent to OpenAI to turn it into text, used once and not stored by us.
- What Lin learns: after looking things up, Lin keeps short notes from public sources (not your personal data), sometimes with the question that led to them, for up to 180 days.
- Network data: your IP address is used to prevent abuse (per-person question limits) and kept only briefly in memory; the web server's access logs are rotated and deleted routinely.
- Cookies and local storage: only to keep you signed in (30 days) and remember settings such as language. No advertising tracking.
Please don't put ID numbers, passwords, API keys, private keys or seed phrases in your questions — remove them before pasting code or error messages.
Service providers
- Anthropic (Claude): writes the answers and runs web searches.
- Cognition (DeepWiki): looks up code and docs of public GitHub repositories; code-related questions are sent to it.
- Ollama: its models answer simple turns such as greetings and small talk.
- OpenAI: turns answers into Lin's voice, and voice questions into text.
- Amazon Web Services: server hosting (United States).
They process data under their own privacy policies; we send them only what is needed to answer. Data may be processed in the United States.
Your choices
- If you don't want to be recorded, type your questions instead of using the microphone.
- To have your questions deleted, contact us through dfmi.app with roughly when you asked and what.
