Cookies are all over the internet. They allow websites to remember your language preferences, the items in your shopping cart, track your browsing on the internet, what videos you like to watch on Youtube and help them recommend better videos, and so on. Learn how to comply with data privacy cookie requirements here.
Cookies for a website are usually a complicated subject. It doesn’t have to be like that. Learn about cookies, HTTP cookies, and third-party cookies here!
Online businesses want to make data-driven decisions. That’s why they need to collect data about user’s behavior on their website, where their users come from, what demographic groups they belong to, and so on. That’s where cookies come in handy.
Cookies are all over the internet. They allow websites to remember your language preferences, the items in your shopping cart, track your browsing on the internet, what videos you like to watch on Youtube, and help them recommend better videos, and so on.
They can be helpful but at a price. That price is the collection of personal data and the related risks.
Businesses must comply with these laws to avoid penalties and losing customers’ trust. That’s why it is essential to understand the following:
- What are cookies
- How do cookies work
- What types of cookies are there
What are cookies?
Cookies are text files that a website or an app sends to the user’s computer, mobile device, or another device to track something and collect data about it. When these small files reach the user’s device, they create an identifier for the specific user and help collect certain categories of data for which that particular cookie has been designed to collect.
For example, an analytics cookie sent to a user’s device to track the web pages they visit on the website will collect data on that user’s browsing behavior. If the cookie was designed to collect data that identifies the user by their demographic characteristics, such as country, age, gender, and others, then it will collect that data, too.
Other cookies are designed to track your browsing history. They collect information from your web browser and store information about your browsing data so advertisers can learn more about you and your interest. As a result, they will be able to serve you with ads tailored to your interests.
Some cookies remember your user preferences on a website, login information, online shopping cart, and authentication, improving your user experience overall.
And in some cases, cookies can be used for malicious purposes, such as spreading malware.
They will track what you tell them to follow.
In many places on the internet, cookies are called HTTP cookies, browser cookies, web cookies, or internet cookies. There is no difference between them.
What types of website cookies are there?
There are many different types of cookies. You can classify tracking cookies depending on various criteria. The most common standards include the following:
The duration criteria classify cookies based on their expiration date, i.e., how long they stay in the users’ device. They can be:
- Session cookies. Session cookies, also known as magic cookies, last only for one browsing session. They expire the moment the user closes the browser. They collect data produced only between the moment of injecting the cookies till the closing of the browser, which is one user session.
- Persistent cookies. Persistent cookies, on the other hand, stay in the device longer, i.e., until the user deletes them. Sometimes, these cookies can expire by themselves if they have an expiry date encoded in the cookie. However, the user can always clear cookies before their expiration date.
The provenance criteria classify cookies based on where they come from. They can be first-party cookies and third-party cookies.
- First-party cookies are stored on your website and injected into your users’ devices as soon as they consent.
- Third-party cookies are the cookies produced by third-party tools that you use for some processing purposes. These third-party tools are connected to your website, but the cookies are not stored there. Instead, they go to the user’s device from a third-party website. These are usually analytic cookies, social media cookies, and similar ones.
- Some web browsers, such as Mozilla Firefox and Apple’s Safari, block third-party cookies by default. Google Chrome will block them starting in 2024.
However, some cookies cannot be easily placed in one of these two groups. A good example is Facebook tracking cookies - produced by Facebook but stored on your website. Although they have been created by a third party (Facebook), and you can extract data collected by them only by using Facebook marketing tools, they are stored on your website like first-party cookies.
Cookies differ based on the purpose they serve your business.
The most general classification based on purpose is on essential and non-essential cookies.
The essential cookies are necessary for the proper functioning of the website. They have to be here to ensure you can use the website or the app.
Non-essential cookies serve purposes that are not necessary for the website’s functioning. All they do is help businesses collect the data they need.
Non-essential cookies can be:
- Analytics cookies. These cookies collect analytics data related to the use of your websites, such as Google Analytics, Mixpanel, Hotjar, and others. They often track users’ behavior based on their IP address. Since the IP address is personal data, you need to comply with the laws regulating such data collection.
- Preferences cookies. These cookies remember users’ choices on your website or app. They reflect the font size, preferred language, dark or light theme, etc.
There are many other types of cookies based on purpose - as many as there are purposes -but these are the most common ones.
Malicious purposes are worth mentioning, too. Some website operators serve the so-called zombie cookies. They can collect data without their knowledge, even after clearing cookies.
This classification is the most important from a legal point of view. The granularity of cookie consent required by the EU cookie laws, such as the ePrivacy Directive and the GDPR, fits the purpose-based classification. See GDPR cookie consent examples.
What does the EU cookie law require?
However, not all consent is created equal. You need to request and obtain consent the right way. Consents collected against the GDPR are invalid, and using cookies upon such collection is unlawful and a reason to get in trouble with the GDPR.
How to obtain consent?
According to the ePrivacy Directive, businesses must obtain explicit user consent before using cookies. That was about enough to comply with EU cookie laws from the introduction of the ePrivacy Directive in 2002 till coming into effect of the GDPR (General Data Protection Regulation) in 2018.
Then, the requirements have become stricter. According to the GDPR, conditions are more detailed. They are prescribed in detail in the law and further tightened by the Planet49 decision of the Court of Justice of the EU and the EDPB guidelines on obtaining consent.
Consent has to be:
- Given freely. You have to allow users to share their consent freely. You must not coerce users into giving consent and should enable them to withdraw it without consequences.
- Specific. Consent is specific when obtained for each specific purpose of processing.
- Unambiguous. This requirement means the consent is valid only if the user consents by affirmative action.
Ensure that the checkboxes or toggles for giving consent for each specific purpose are not pre-checked. The data protection authority fined Planet49 because they had the checkboxes pre-checked.
Also, do not pre-check checkboxes for giving consent for each specific purpose.
- Easily withdrawn. GDPR requires businesses to allow users to withdraw the previously given consent as quickly as it has been given. This doesn’t make obtaining the consent invalid but violates the GDPR.
Website owners generally request cookies consent from the user when they arrive on the website for the first time. The most common way to do so is by a pop-up cookie banner adjusted to the legal requirements of the specific law that applies to the company and the user.
Do other countries have cookie laws similar to the EU cookie laws?
Yes, there are many countries all over the world that follow the example of the GDPR and the ePrivacy Directive. As a result, many of them require businesses to obtain explicit user consent before using cookies.
However, not all of them have strict requirements for obtaining valid consent. Therefore, compliance with one law doesn’t mean compliance with all the other laws that require it.
You have to do your due diligence to ensure you know your situation’s particular legal requirements.
How to comply with the EU cookie laws?
You need to:
- Block all the cookies before obtaining consent, except for the essential cookies.
- Request explicit cookie consent from users by a cookie banner.
- The cookie banner must allow users to take affirmative action for giving cookie consent.
- The cookie banner also needs the allow users to decline cookies.
- You must not protect the website content with a cookie wall.
- You must not bundle the cookie consent with the Terms and Conditions.
- You need to request consent for each specific processing purpose.
- The checkboxes, toggles, or other mechanisms for giving consent for each specific purpose must be set off by default, and the user should be allowed to check them out or turn them on to give consent through affirmative action.
- Do not assume that browsing the website means consent.
- Keep records of all the consent responses.
- Allow users to withdraw consent without a hassle, as easily as they had given it.
