隱私權政策

不會記錄的

你問的內容與工具參數：AI 助理送來的請求內容（例如查詢的股票代號、資料集、條件）不會被記錄或保存。
不需要帳號、不用登入、不設 cookie。

會記錄的

服務架設在 Cloudflare Workers。Cloudflare 會自動為每個請求保存一筆紀錄（Workers Logs），內容包括：

連線來源的 IP 位址，以及 Cloudflare 依 IP 推估的地理位置（國家、城市、郵遞區號、經緯度）與網路業者（ASN）。
User-Agent 與其他 HTTP 請求標頭。依 MCP 協定，部分請求的標頭會帶有呼叫的方法與工具名稱（例如 snapshot.stock），但不含參數。
請求網址、回應狀態碼、處理時間。

透過 Claude 等 AI 助理使用時，連線來源通常是該 AI 服務的伺服器，而不是你的裝置。

交易所會看到什麼

我們向交易所取資料時，只送出查詢本身（資料集或代號）與可辨識本服務的 User-Agent，不會附上你的問題。但向臺灣證券交易所（OpenAPI 與基本市況報導站）發出的請求，Cloudflare 依其平台規則會在 CF-Connecting-IP 標頭附上連線來源的 IP 位址，本服務無法移除（Cloudflare 說明）；向臺灣期貨交易所的請求不會附上。資料集常直接取自快取（最多 1 小時），這時不會對交易所發出請求；即時報價不快取。

用途、保存與分享

用途：只用於排查服務問題（例如錯誤、逾時）與防止濫用。
保存期間：3 天，之後由 Cloudflare 自動刪除。
分享：不出售、不提供給第三方。Cloudflare 以代管服務商的身分處理這些紀錄，適用 Cloudflare 隱私權政策。
你與 AI 助理之間的對話由該 AI 服務處理，適用其隱私權政策；本服務只收到 AI 送來的工具呼叫。

What we do not record

What you ask, and tool arguments: the content of requests your AI assistant sends (for example the stock codes, datasets or filters) is not logged or stored.
No account, no sign-in, no cookies.

What is recorded

The service runs on Cloudflare Workers. Cloudflare automatically keeps a log entry for every request (Workers Logs), containing:

The client IP address, plus the location Cloudflare derives from it (country, city, postal code, latitude/longitude) and the network (ASN).
The User-Agent and other HTTP request headers. Under the MCP protocol some requests carry the method and tool name in a header (for example snapshot.stock), but never its arguments.
The request URL, response status and processing time.

When you use the service through an AI assistant such as Claude, the connection usually comes from that assistant's servers, not from your device.

What the exchanges see

When we fetch data from the exchanges we send only the query itself (a dataset or code) and a User-Agent that identifies this service, never your question. However, on requests to the Taiwan Stock Exchange (its OpenAPI and market information site), Cloudflare's platform adds the connecting IP address in a CF-Connecting-IP header, which this service cannot remove (Cloudflare documentation); requests to the Taiwan Futures Exchange do not carry it. Datasets are often served from cache (up to 1 hour), in which case no request reaches the exchange; live quotes are never cached.

Use, retention and sharing

Use: only to troubleshoot the service (errors, timeouts) and prevent abuse.
Retention: 3 days, after which Cloudflare deletes the logs automatically.
Sharing: never sold or given to third parties. Cloudflare processes the logs as our hosting provider under the Cloudflare Privacy Policy.
Your conversation with the AI assistant is handled by that assistant's provider under its own privacy policy; this service only receives the tool calls the assistant sends.
