GDPR, cookies and compliance 

Even though cookies are mentioned only once in the GDPR, cookie consent is nonetheless a cornerstone of compliance for websites with EU-located users.

This is because one of the most common ways for personal data to be collected and shared online is through website cookies. The GDPR sets out specific rules for the use of cookies.

That’s why end-user consent to cookies is the GDPR’s most used legal basis that allows websites to process personal data and use cookies. 

Cookie Consent Banner: Implement a cookie consent banner that informs users about the use of cookies on your website. This banner should allow users to either accept or reject cookies and provide them with the option to learn more about the types of cookies used.

Cookie Categories: Categorize cookies used in your application. Common categories include essential, functional, analytical, and marketing cookies. This classification helps users make informed choices about which cookies they want to accept.

Consent Management: Store user consent preferences in a secure manner. If a user consents to certain types of cookies, set a cookie or store the preference in your database. Make it easy for users to change their preferences at any time.

Cookie Documentation: Maintain a clear and accessible cookie policy or documentation explaining the purpose of each type of cookie used, their duration, and any third-party services involved. Keep this information up-to-date.

Anonymize IP Addresses: If you're using Google Analytics or similar tools, configure them to anonymize IP addresses. This helps protect user privacy.

Data Retention: Ensure that your application doesn't retain user data longer than necessary. Implement automated data deletion processes to comply with GDPR's data minimization principle.

Data Access and Portability: Provide users with the ability to access their data and, if requested, export it in a machine-readable format.

Data Protection Impact Assessment (DPIA): Perform DPIAs for data processing activities that present a high risk to user privacy.

Third-Party Services: Review and document the use of third-party services and their GDPR compliance. Ensure that their data processing aligns with GDPR requirements.

User Education: Educate your users about their rights and your data protection practices. This could include creating a privacy policy and including links to it in your application.
