Temporary logs, including full IP addresses, are deleted within 24-48 hours. Permanent logs exclude personally identifiable information and IP addresses, retaining only city/metro-level location data for debugging and abuse analysis. A subset of this data is randomly sampled for permanent storage after two weeks. Permanent logs include request details like domain name, type, transport protocol, client's ISP, user's geolocation, response codes, caching information, and timing.

View the [current version](/speed/public-dns/privacy) or [all past versions](/speed/public-dns/archive/privacy-changes).\n\nWe understand that our users need to know what we do with information we collect\nwhen you use our services.\nIf you'd like to read the main policy which Google adheres to, see the\n[Privacy Center](//www.google.com/intl/en/policies/privacy/).\n\nHowever, if you're reading this page, you probably want some specific,\nrapid answers about what happens to your data when you use Google Public DNS.\nWe designed the product to be fast, so let's get to the point quickly on privacy\nas well.\n| **Important:** We built Google Public DNS to make the web faster and to retain as little information about usage as we could, while still being able to detect and fix problems. Google Public DNS does not permanently store personally identifiable information.\n\nWhat we log\n-----------\n\nGoogle Public DNS stores two sets of logs: temporary and permanent.\nThe temporary logs store the full IP address of the machine you're using.\nWe have to do this so that we can spot potentially bad things like DDoS attacks\nand so we can fix problems, such as particular domains not showing up for\nspecific users.\n\nWe delete these temporary logs within 24 to 48 hours.\n\nIn the permanent logs, we don't keep personally identifiable information or IP\ninformation.\nWe do keep some location information (at the city/metro level) so that we can\nconduct debugging, analyze abuse phenomena.\nAfter keeping this data for two weeks, we randomly sample a small subset for\npermanent storage.\n\nWe don't correlate or combine information from our temporary or permanent logs\nwith any personal information that you have provided Google for other services.\n\nFinally, if you're interested in knowing what else we log when you use Google\nPublic DNS, here is the full list of items that are included in our permanent\nlogs:\n\n- Request domain name, e.g. www.google.com\n- Request type, e.g. A (which stands for IPv4 record), AAAA (IPv6 record), NS, MX, TXT, etc.\n- Transport protocol on which the request arrived, i.e. TCP, UDP, or [HTTPS](/speed/public-dns/docs/dns-over-https)\n- Client's AS (autonomous system or ISP), e.g. AS15169\n- User's geolocation information: i.e. geocode, region ID, city ID, and metro code\n- Response code sent, e.g. SUCCESS, SERVFAIL, NXDOMAIN, etc.\n- Whether the request hit our frontend cache\n- Whether the request hit a cache elsewhere in the system (but not in the frontend)\n- Absolute arrival time in seconds\n- Total time taken to process the request end-to-end, in seconds\n- Name of the Google machine that processed this request, e.g. machine101\n- Google target IP to which this request was addressed, e.g. one of our anycast IP addresses (no relation to the user's IP)"]]
