您的隐私权
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
本文档提供了以下方面的重要信息：我们在您使用 Google 公共 DNS 时收集的数据，我们存储这些数据的时长以及我们如何使用这些数据。您还可以阅读我们的服务条款。
我们的承诺
我们非常重视您的隐私。Google 公共 DNS 遵守 Google 隐私权政策。此外，Google 不会使用通过公共 DNS 服务收集的任何个人信息来定位广告。
除了解决安全性和滥用行为之外，我们不会将 Google 公共 DNS 日志中的个人信息与使用任何其他 Google 服务的信息关联起来或关联。
我们收集的有关 DNS 查询的信息存储在两种类型的日志中，每种日志详见下文：
临时 DNS 日志
临时日志是唯一存储 IP 地址和 DNS 查询的日志。具体而言，临时日志包括：
- 发送 DNS 查询的设备的 IP 地址
- 为永久日志收集的技术信息（见下文）
- 对于 DNS-over-HTTPS (DoH)：内容类型和接受 HTTP 标头
这些日志会在 24-48 小时内遭到删除。它们仅用于以下原因：
- 识别和缓解我们视为滥用或其他恶意行为的安全威胁或活动；
- 修复、维护和改进 Google DNS 服务；以及
- 可生成非个人身份信息的汇总 DNS 使用情况摘要。
为了解决安全和滥用问题，我们可能会将临时日志中的信息保留 48 小时以上，每种情况都仅用于解决此类问题。
永久 DNS 日志
永久日志是对临时 IP 的采样，其中的 IP 地址会被移除并替换为城市或区域级位置。因此，该永久日志不包含任何个人信息。永久日志中会记录以下信息：
- 请求的域名
- 请求类型（
A、AAAA、NS、MX、TXT 等）
- 请求大小
- 传输协议（
TCP、UDP、TLS 或 HTTPS）
- 客户的自治系统编号
- 用户的地理位置：国家/地区、区域和城市（不超过 1 平方公里和 1000 位用户）
- DNS 响应代码
- Google DNS 服务器信息
- 时间戳
- 处理时间
- 响应 DNS 标志（包括
AD、CD、DO、RD 和 TC）
- 响应大小
- EDNS 版本
- EDNS 选项
- EDNS 客户端子网 (ECS)（IP 协议和前缀长度 - 不包括客户端 IP 地址）
- 对于 DNS-over-HTTPS (DoH)：
- 与 HTTP 路径（
/dns-query 或 /resolve）对应的版本字符串
- 响应 HTTP 编码，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."]]
