A device is a computer that can be used to access our website or services. For example, a device could be a desktop, tablet or smartphone.
An HTTP Referrer is information transmitted to a destination webpage by a web browser, typically when you click a link to that webpage. The HTTP Referrer contains the URL of the last webpage the browser visited.
Every device connected to the Internet is assigned a number known as an Internet protocol (IP) address. These numbers are usually assigned in geographic blocks and are typically controlled by your Internet Service Provider (ISP), your company, or your university. An IP address can often be used to identify the location from which a device is connecting to the Internet. Please note that third parties have mapped the assignments of IP addresses by ISPs with specificity to postal code and exact city for broadband IP address and are also often mapped to college campuses, specific businesses, hotels, airports or conference centers. Mobile IP address often can only be mapped to a specific carrier’s gateway. However, most of the Wi-Fi routers in the world have been mapped by third parties to precise latitude and longitude and many Wi-Fi routers correspond to home addresses. IP address can be used to combat fraud and compliance with geographical legal restrictions and can be used to target advertising. When Sojern stores an IP address, we store it in truncated or encrypted form.
Local storage enables websites to store and retrieve data in a browser on a device. When used in “local storage” mode, it enables data to be stored across sessions (for example, so that the data are retrievable even after the browser has been closed and reopened). One technology that facilitates web storage is HTML 5. Other technologies include local shared objects, sometimes known as “Flash Cookies”. For more information, please see our Online Tracking Technologies and Advertising Policy.
Like most websites, our servers automatically record the page requests made when you visit our websites. These “server logs” or “log data” typically include your web request, IP address, browser type, browser language, the date and time of your request and one or more cookies that may uniquely identify your browser.
This is information that on its own does not permit direct association with any specific individual. For example, we consider the following to be non-personally identifiable information: your zip code, approximate location (e.g. region, city, zip), your browser type, cookie IDs, non-unique device identifiers, websites you have visited, and advertisements viewed or clicked. We also consider aggregated, de-identified and/or anonymized data to be non-personally identifiable information. Not all jurisdictions have the same definition for personal information and non-personally identifiable information.
Personal information is data that can be used to identify or contact a particular individual, such as the individual’s name, email address or billing information, or other data which can be reasonably linked to that data or to that individual’s specific computer or device. When anonymous or non-personal information is directly or indirectly linked with personal information, this anonymous information is also treated as personal information. Where required to do so by law, we will consider persistent identifiers that are not anonymized, de-identified or aggregated as personal information. Not all jurisdictions have the same definition for personal information and non-personally identifiable information.
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. Pixel refers to the software code that is placed within a web page in order to trigger the placing of cookies and transmits information to us or our third party service providers. This enables two websites to share information. The resulting connection can include information such as a device’s IP address, the time a person viewed the pixel, an identifier associated with the browser or device, the type of browser being used and the URL of the web page from which the pixel was viewed. A pixel tag is also known as a web beacon or Clear GIFs. There may or may not be a visible graphic image associated with the pixel, and often the image is designed to blend into the background of a web page or email.
A unique device identifier (sometimes called a universally unique ID or UUID) is a string of characters that is incorporated into a device by its manufacturer and can be used to uniquely identify that device (for example an IMEI-number of a mobile phone). 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.
