An anonymous identifier is a random string of characters that is used for the same purposes as a cookie on platforms, including certain mobile devices, where cookie technology is not available.
A cookie is a small file containing a string of characters that is sent to your computer when you visit a website. When you visit the website again, the cookie allows that site to recognise your browser. Cookies may store user preferences and other information. You can reset your browser to refuse all cookies or to indicate when a cookie is being sent. However, some website features or services may not function properly without cookies.
You may access some of our services by signing up for a Google Account and providing us with some personal information (typically, your name, email address and a password). This account information will be used to authenticate you when you access Google services and protect your account from unauthorised access by others. You can edit or terminate your account at any time through your Google Account settings.
Every computer connected to the Internet is assigned a unique number known as an Internet protocol (IP) address. Since these numbers are usually assigned in country-based blocks, an IP address can often be used to identify the country from which a computer is connecting to the Internet.
Non-personally identifiable information
This is information that is recorded about users so that it no longer reflects or references an individually identifiable user.
This is information which you provide to us which personally identifies you, such as your name, email address or billing information, or other data which can be reasonably linked to such information by Google.
A pixel tag is a type of technology placed on a website or within the body of an email for the purpose of tracking activity on websites, or when emails are opened or accessed, and is often used in combination with cookies.
Sensitive personal information
This is a particular category of personal information relating to confidential medical facts, racial or ethnic origins, political or religious beliefs or sexuality.
Like most websites, our servers automatically record the page requests made when you visit our sites. These “server logs” typically include your web request, Internet Protocol address, browser type, browser language, the date and time of your request and one or more cookies that may uniquely identify your browser.
Here is an example of a typical log entry where the search is for “cars”, followed by a breakdown of its parts:
22.214.171.124 - 25/Mar/2003 10:15:32 -
Firefox 1.0.7; Windows NT 5.1 - 740674ce2123e969
126.96.36.199is the Internet Protocol address assigned to the user by the user’s ISP; depending on the user’s service, a different address may be assigned to the user by their service provider each time that they connect to the Internet;
25/Mar/2003 10:15:32is the date and time of the query;
http://www.google.com/search?q=carsis the URL requested, including the search query;
Firefox 1.0.7; Windows NT 5.1is the browser and operating system being used; and
740674ce2123a969is the unique cookie ID assigned to this particular computer the first time that it visited Google. (Cookies can be deleted by users. If the user has deleted the cookie from the computer since the last time s/he visited Google, then it will be the unique cookie ID assigned to the user the next time that s/he visits Google from that particular computer.)
Unique device identifier
A unique device identifier is a string of characters that is incorporated into a device by its manufacturer and can be used to uniquely identify that device. Different device identifiers vary in how permanent they are, whether they can be reset by users and how they can be accessed. A given device may have several different unique device identifiers. Unique device identifiers can be used for various purposes, including security and fraud detection, syncing services such as a user’s email inbox, remembering the user’s preferences and providing relevant advertising.
