New cookie rules 2025: How to protect your data effectively!
Today, June 23, 2025, all signs point to change when it comes to the regulation of cookies and data protection. German companies are required to adapt to new and strict guidelines that have come into force in recent years. The Telecommunications Digital Services Data Protection Act, better known as TDDDG, has fundamentally changed the rules of the game for the use of cookies. Introduced in 2021 as TTDSG, the TDDDG implements important regulations and stipulates that access to information on end devices is only permitted with the consent of users. As dr-datenschutz.de reports, this eliminated ambiguities that had previously existed.
The law provides clear guidelines. Cookies that are not technically necessary may only be stored with the active consent of the user. This applies in particular to the so-called consent banners, which must inform users about the use of cookies. These banners must provide clear information, an opt-in function and the opportunity to object. In the so-called “cookie ruling”, the BGH decided that these regulations must be in line with European requirements.
A new cookie regulation
A further step in the legal regulation came on September 4, 2024 in the form of a new regulation on consent management. This is based on the TDDDG and aims to improve the surfing experience for users and reduce annoying cookie banners. According to externer-datenschutzanwalt-dresden.de, users can now permanently save their cookie decisions, which should make dealing with cookies much easier.
However, companies are forced to rethink their cookie practices because the requirements of the GDPR remain in place. These regulations apply to all companies that process data from EU citizens. Violations can result in significant fines of up to 20 million euros or up to 4% of annual turnover. Companies are not left indifferent by this pressure and are required to make their cookie policies transparent and optimize their consent processes.
Clarity for consumers
The new regulation takes a step towards greater clarity and transparency for consumers. Cookie banners must now contain detailed information about the cookies used. In addition, an equivalent design of consent and rejection options is required. In concrete terms, this means that users must not only be able to give consent, but also have an easy way to refuse.
To meet the demands, companies must implement best practices such as clear lines of communication, granular consent options and the use of recognized consent services. The time for tacit consent is over; times demand active action. Reports from KFV-MSP show that this represents a fundamental change in data protection in Germany, which is of great importance not only for companies but also for consumers.
