Best Practices for Cookie Expiration and GDPR Compliance

Ever wondered how websites recognize you when you come back or change your experience based on what you’ve done before? Cookies, which are little text files that websites you visit leave on your device, are the key. Cookies are essential for improving the user experience but can present privacy and security issues. 

One of the most important characteristics of cookies is their finite lifetime on your device. Cookies are essential for providing users with individualized online experiences. This short blog will delve into the information about cookie expiration and how Seers will help you in this regard.

What is cookie expiration?

The term “cookie expiration” refers to the length of time that a cookie remains active on a user’s web browser. A website stores a small text file called a cookie when a user visits it.

It stays active for a certain period after someone initially places it. Cookies help improve the online experience by remembering user preferences and settings, like usernames and passwords. Temporary (session) cookies and permanent cookies are the two most common kinds.

Types of cookies

When a user closes their browser, or the session ends, the system deletes the data stored in Session Cookies. The cookie session expires and renews when you reopen the browser or site. Session cookies are transient and let users do certain tasks on a website. The browser removes session cookies and associated data when it is closed.

Persistent Cookies remain on the user’s device even after they have finished browsing and closed the website. Websites can remain on a user’s device for varying durations. This can range from a few days to several months or even years after they have finished browsing. Persistent cookies contain login credentials, user preferences, and tracking data.

Cookies can expire, which helps websites show personalized content and experiences based on what a user has done before. To balance personalization and user privacy in the digital age, it’s important to use cookie expiration best practices.

How long do cookies last?

Persistent cookies can have varying validity periods based on the website’s purpose and the data it wants to retain. The length of time for which a persistent cookie remains valid can differ. The specific purpose of the website and the data it aims to preserve determine this variation.

Some websites may have their persistent cookies expire after a few days. While others will make them linger for a number of months or even years at a time. 

Cookies have many valid uses. However, some cookies may have longer expiration dates. We use these longer expiration dates to track user activity for advertising or research purposes.

Certain countries and areas, such as the European Union with the GDPR, have implemented laws regarding website cookies. These laws require websites to obtain user permission for non-essential cookies and allow users to modify their cookie settings. We created these policies to address concerns over the protection of personal information.
