1. What Are Cookies
A cookie is a small text file which is placed onto your device (e.g., computer, smartphone, or other electronic device) when you visit our website to store a range of information, for example, your language preference, or browser and device you are using to view the website. Those cookies are set by us and called first-party cookies. We also use third-party cookies, which are cookies from a domain different than the domain of our website, for our advertising and marketing efforts.
Session Cookies
Session cookies expire each time you close your browser and do not remain on your device afterwards. These cookies allow our website to link your actions during a particular browser session.
Persistent Cookies
Persistent cookies will remain on your device for a period of time, and will expire on a set expiration date, or when you delete them manually from your cache. These cookies are stored on your device in between browser sessions and allow your preferences and actions across our website to be remembered.
2. Similar Technologies
- Web Beacons (Pixel Tags) - Small, transparent images embedded into websites or emails that communicate with our server to acquire information such as technical specifications of your device, operating systems, and settings. They can track your activities during a session and help us improve our email communication.
- Software Development Kits (SDKs) - Third-party software development kits that may be installed in our Service. SDKs help us understand how you interact with our Service and collect certain information about the device and network you use to access the Service.
- HTML5 Local Storage - HTML5 contains functionality that allows information to be stored locally within the browser's data files. It operates similarly to cookies but can hold greater amounts of information and does not rely on an exchange of data with the website's server.
- Fingerprinting - A technique that involves combining a set of information elements to uniquely identify a particular device. These elements include device configuration, CSS information, JavaScript objects, installed fonts, plugins, HTTP header information, and clock information.
- Device Identifiers - Identifiers comprised of numbers and letters unique to each specific device, such as Apple's ID for Advertisers (IDFA) and Google's Android Advertising ID (AAID). They are used to recognize you across different apps and devices for marketing purposes. You can reset your device identifier or opt out of personalized advertising in your device settings.
