Cookies files – everything you need to know

What are cookies files?

They play a key role in providing a smooth and personalized experience, allowing websites to “remember” the user and their preferences.

Cookies store information such as:

• language preferences;
• password;
• login;
• page layout;
• contents of the shopping cart.

As a result, the user is freed from the necessity of entering data each time, which significantly improves the interaction process with the website. Cookies also serve as an important tool for advertisers, enabling precise targeting of advertisements and increasing the effectiveness of campaigns. Furthermore, they provide website owners with valuable information about user behavior, website traffic and the popularity of specific content, allowing for in-depth analysis and optimization of the website.

Are cookies files mandatory?

There are cookies that are absolutely necessary for the proper functioning of the website. They enable basic functions such as navigating through the site, logging into a user account, or adding products to the cart. Their presence is essential for smooth interaction with the website, therefore they do not require prior user consent.

A different category consists of analytical cookies, used to monitor user behavior and personalize content. In this case, due to the potential impact on user privacy, obtaining explicit consent before installing them on the device is necessary.

How long are cookies stored?

The storage time of cookie files is diverse and depends on several factors – primarily on their type and settings determined by the website owner.

Session cookies exist only during the duration of the browser session and are automatically deleted after it is closed. They are used to store temporary information, such as the contents of a shopping cart or login status.

Permanent cookies are stored on the user’s device for a specific period of time, even after closing the browser. Their lifespan can range from a few days to several years, depending on their purpose. They are used to remember long-term information, such as user preferences or login data.

What is a cookies policy?

Cookies policy is a document in which users are informed about the types, purposes, and rules for using cookies on the website. It is a key element of transparency in the processing of personal data. The cookie policy should be clear, understandable, and easily accessible to users. For this reason, it is usually placed in the footer of the page or in a pop-up window.

How to write a cookies policy?

According to the requirements of Article 173 of the Telecommunications Law, every internet website using cookies files is obliged to inform users about this fact. In practice, this is implemented by displaying banners that require the user to make an informed decision.

The cookies policy should provide the following information about:

• owner/operator of the service;
• types of cookie files;
• purposes of using cookie files (including permanent, session, and analytical files);
• collected data (including IP address, user preferences);
• storage time;
• options for managing cookies files (including the ability to delete them or change browser settings);
• privacy policy (location where the full privacy policy is available).
