What are cookies?
A cookie is a text file stored by a web browser in any device used to access a website, and it holds information regarding the user’s visit and his/her preferences. When the user returns, the browser provides the cookie with the stored information to the site.
What cookies are used for?
Cookies are used for adjusting a website’s content to fit a user’s preferences and optimize the website. They store useful information that improve the user’s experience of a website. They are most commonly used for:
- Storing login information so that a user does not need to re-login on every visit.
- Recognizing the type of device a user is browsing and any preferences applied to optimize the website specifically for the device.
- Creating statistics that help website owners to understand how their users interact with their website, which allows them to improve their structure and content.
What types of cookies are used?
There are two types of cookies: persistent cookies and session cookies. Persistent cookies remain on your hard drive for a period of time specified in the cookie’s file parameters or until removed manually. When you return to a website and it requires you to login again despite previously storing your login information, it is usually because the persistent cookie expired; this helps to increase security while maintaining accessibility. Session cookies are used temporarily and expire once the website or browser is closed. They are used to track user activity on a website during a single visit. When a website requires that you verify your age or location once every visit before allowing you to view content and without requiring additional personal details, that is a session cookie at work.
Do cookies include personal data?
If there is a need for the collection of personal information, such as for creating accounts, then cookies may store personal information. However, it is required by data protection law that users are informed of the collection of personal data. This data will also be encrypted to render it inaccessible for unauthorized users.
By default, browsers are configured to accept cookies. However, these settings may be changed to block cookies entirely, or to inform the user each time they are used. Detailed information about cookies and the options associated with them are available in each browsers’ settings.
You can easily remove any cookies that have been created in the cookie folder of your browser.

What Cookies Do to Your Devices
Cookies are browser dependent and are essentially text files containing information that browsers save in one of their specific folder. By themselves, cookies pose no risk since they do not contain virus in any form nor do they spy on your devices content to compromise security. They are used to make online surfing faster and easier by making the sites you’ve visited remembering who you are (through IP address or passwords, along with your own preferences).
