您的隱私權
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
本文件提供 Google 公用 DNS 所蒐集資料的重要資訊、儲存時間長短，以及這些資料的使用方式。您也可以參閱《服務條款》。
我們的承諾
Google 非常重視使用者的隱私，Google 公用 DNS 符合《Google 隱私權政策》的規定。此外，Google 不會使用透過公開 DNS 服務收集的任何個人資訊來指定廣告。
除非是解決安全性和濫用行為，否則 Google 公開 DNS 記錄中的個人資訊不會與任何其他 Google 服務的資訊相關聯或建立關聯。
我們針對 DNS 查詢所蒐集的資訊會儲存在兩種記錄中，詳情如下：
暫時 DNS 記錄
暫時記錄是儲存 IP 位址和 DNS 查詢的唯一記錄。具體來說，暫時記錄包括：
- 傳送 DNS 查詢的裝置 IP 位址
- 為永久記錄收集的技術資訊 (請見下方說明)
- 適用於 DNS-over-HTTPS (DoH)：Content-Type 和 Accept HTTP 標頭
這些記錄會在 24 到 48 小時內刪除。僅用於下列原因：
- 找出並判定我們認定為濫用或惡意的安全性威脅或活動；
- 修正、維護及改善 Google DNS 服務。
- 來產生無法識別個人身分的 DNS 使用摘要。
為解決安全性和濫用行為，我們可能會暫時保留臨時記錄中的資訊，時間超過 48 小時。
永久 DNS 記錄
永久記錄檔是臨時記錄檔的樣本，用於移除 IP 位址，並由城市或區域層級位置取代。因此，永久記錄不含任何個人資訊。永久記錄會記錄下列資訊：
- 要求的網域名稱
- 要求類型 (
A、AAAA、NS、MX、TXT 等)
- 要求大小
- 傳輸通訊協定 (
TCP、UDP、TLS 或 HTTPS)
- 客戶自主的系統號碼
- 使用者的地理位置：國家/地區、區域和城市 (指定範圍不超過 1 平方公里和 1,000 名使用者)
- DNS 回應代碼
- Google DNS 伺服器資訊
- 時間戳記
- 處理時
- 回應 DNS 旗標 (包括
AD、CD、DO、RD 和 TC)
- 回應大小
- EDNS 版本
- EDNS 選項
- EDNS 用戶端子網路 (ECS) (IP 通訊協定和前置字串長度，不含用戶端 IP 位址)
- 如為 DNS-over-HTTPS (DoH)：
- 與 HTTP 路徑對應的版本字串 (
/dns-query 或 /resolve)
- 回應 HTTP 編碼，例如
application/dns-message 或 json

Temporary logs, including IP addresses and query details, are deleted within 24-48 hours and used for security, service improvement, and usage summaries. Permanent logs sample temporary logs, removing IP addresses and replacing them with city-level location data, and log DNS request and response characteristics, but no personal information. Google does not link data from the logs with other google services for advertising purposes. Both types of logs are retained to resolve security and abuse issues.\n"],null,["# Your Privacy\n\nThis document provides important information about the data that we collect\nwhen you use Google Public DNS, how long we store it, and how we use it. You\ncan also read our [Terms of Service](/speed/public-dns/terms).\n\nOur Commitment\n--------------\n\nWe take your privacy very seriously. Google Public DNS adheres to the\n[Google Privacy Policy](https://policies.google.com/privacy). Moreover, Google does not use any personal\ninformation collected through the Public DNS service to target ads.\n\nWe do not correlate or associate personal information in Google Public DNS\nlogs with your information from use of any other Google service except for\naddressing security and abuse.\n\nInformation that we collect\n---------------------------\n\nThe information that we collect about your DNS queries is stored in two types\nof logs, each detailed below:\n\n- [Temporary DNS Logs](#temporary-dns-logs)\n- [Permanent DNS Logs](#permanent-dns-logs)\n\n### Temporary DNS Logs\n\nTemporary logs are the only logs that store both your IP address and your DNS\nquery. Specifically, the temporary logs include:\n\n- the IP address of your device sending the DNS query\n- the technical information collected for Permanent Logs (see below)\n- for DNS-over-HTTPS (DoH): the Content-Type and Accept HTTP headers\n\nThese logs are subject to our deletion processes within 24-48 hours. They are\nonly used for the following reasons:\n\n- to identify and mitigate security threats or activity that we deem abusive or otherwise malicious,\n- to fix, maintain, and improve Google DNS services, and\n- to generate aggregate non-personally identifiable DNS usage summaries.\n\nTo address security and abuse issues, we may retain information from the\ntemporary logs for longer than 48 hours, in each case solely for the limited\npurpose of resolving such issues.\n\n### Permanent DNS Logs\n\nThe permanent logs are a sampling of the temporary logs where your IP address\nis removed and replaced by a city or region-level location. Thus, the\npermanent logs contain no personal information about you. The following\ninformation is logged in the permanent logs:\n\n- Requested domain name\n- Request type (`A` , `AAAA` , `NS`, `MX`, `TXT`, etc.)\n- Request Size\n- Transport protocol (`TCP`, `UDP`, `TLS`, or `HTTPS`)\n- Client's autonomous system number\n- User's geolocation: country, region, and city (no more specific than 1 km² and 1000 users)\n- DNS Response code\n- Google DNS server information\n- Timestamp\n- Processing time\n- Response DNS flags (including `AD`, `CD`, `DO`, `RD`, and `TC`)\n- Response size\n- EDNS version\n- EDNS option\n- EDNS Client Subnet (ECS) (IP protocol and prefix length -- excluding the client IP address)\n- For DNS-over-HTTPS (DoH):\n - Version string corresponding to HTTP path (`/dns-query` or `/resolve`)\n - Response HTTP encoding, such as `application/dns-message` or `json`\n\nPrevious Versions\n-----------------\n\nYou can see [all past versions](/speed/public-dns/archive/privacy-changes) of this policy."]]
