Berlin Court Ruling Deals Major Blow to Meta’s Data-Sharing Practices: What It Means for Users and Privacy Reform
In a landmark decision that could reshape how tech giants handle user data, a Berlin court has ruled that WhatsApp is prohibited from sharing user data with its parent company, Meta (formerly Facebook). The ruling, issued by the Landgericht Berlin II on March 13, 2026, marks a significant victory for privacy advocates and consumer rights groups after nearly a decade of legal battles. The court found that WhatsApp’s data-sharing practices violated European privacy laws, particularly regarding the consent mechanisms used to transfer personal information—including the phone numbers of non-users—to Meta’s broader ecosystem.
Linda Park, Editor of Tech at World Today Journal, explains the broader implications: “This ruling isn’t just about WhatsApp or Meta. It’s a signal to the entire tech industry that European regulators are serious about enforcing data protection laws, especially when it comes to cross-platform data sharing. The decision could force companies to rethink how they collect, store, and transfer user information—both within and outside the EU.”
The case, brought by Germany’s Verbraucherzentrale (Consumer Advocacy Center), centered on WhatsApp’s data-sharing policies, which required users to consent to the transfer of their address book data—including contacts who did not use the app—to Meta. The court ruled that the consent obtained via push notifications was insufficient under the General Data Protection Regulation (GDPR), Europe’s strict privacy framework. The decision also extends protections to individuals who do not use WhatsApp but whose phone numbers were uploaded by others, a practice the court deemed unlawful without explicit consent.
The Ruling: Key Findings and Legal Basis
The Landgericht Berlin II based its decision on several critical violations of the GDPR, which has been in effect since May 25, 2018. The court’s findings include:
- Inadequate Consent Mechanisms: The court determined that WhatsApp’s push notification system, which asked users to agree to data-sharing terms, did not meet GDPR standards for “freely given, specific, informed, and unambiguous” consent. The ruling noted that users were not provided with clear, granular options to refuse data sharing without losing access to the app’s core functionality.
- Non-User Protections: The court emphasized that the GDPR protects the personal data of individuals even if they are not direct users of a service. By uploading the phone numbers of non-users to Meta’s servers, WhatsApp violated their privacy rights, as these individuals had not consented to their data being processed.
- Cross-Border Data Transfers: The ruling also touched on the legality of transferring data from the European Economic Area (EEA) to the United States, a practice Meta has relied on for years. The court did not explicitly rule on the validity of Standard Contractual Clauses (SCCs), a legal mechanism used by Meta to justify such transfers, but the decision raises questions about whether these clauses are sufficient to protect user data under GDPR standards. This aligns with broader concerns in the EU about data transfers to the U.S., where surveillance laws like the Clarifying Lawful Overseas Use of Data (CLOUD) Act have been criticized for conflicting with European privacy rights.
The court’s decision is the latest in a series of legal challenges Meta has faced in Europe over its data practices. In 2023, the company was fined €1.2 billion by Ireland’s Data Protection Commission for unlawfully transferring EU user data to the U.S. Under SCCs, a ruling Meta is currently appealing. The Berlin court’s decision adds further pressure on the company to reform its data-sharing policies or risk additional penalties.
Why This Ruling Matters for Users—and Non-Users
The implications of the Berlin court’s decision extend far beyond Meta’s platforms. Here’s what it means for different stakeholders:
For WhatsApp Users
- Greater Control Over Data: The ruling reinforces that users must have meaningful choices about how their data is shared. WhatsApp may now be required to implement more transparent consent mechanisms, such as allowing users to opt out of specific data-sharing practices without losing access to the app.
- Reduced Data Exposure: If Meta complies with the ruling, users can expect fewer of their personal details—such as their contact lists—to be shared with other Meta-owned platforms like Facebook and Instagram. This could limit the company’s ability to target users with personalized ads based on their WhatsApp activity.
For Non-Users
- Protection from Unwanted Data Collection: One of the most significant aspects of the ruling is its protection of individuals who do not use WhatsApp. The court’s decision makes it clear that companies cannot process the personal data of non-users without explicit consent, even if that data is provided by a third party (e.g., a friend or family member who uses the app).
- Precedent for Broader Privacy Rights: The ruling sets a legal precedent that could be cited in future cases involving other apps or services that collect data from non-users, such as social media platforms that scan users’ address books or messaging apps that upload contact lists.
For the Tech Industry
- Increased Scrutiny of Data-Sharing Practices: The decision sends a clear message to tech companies that European regulators are closely monitoring how they handle user data, particularly when it comes to cross-platform sharing. Companies like Google, Apple, and Microsoft, which also operate multiple services, may need to review their data-sharing policies to ensure compliance with GDPR.
- Challenges for U.S.-Based Companies: The ruling highlights the ongoing tension between U.S. And EU data protection laws. Companies headquartered in the U.S. But operating in Europe must navigate conflicting legal frameworks, particularly around data transfers. The Berlin court’s decision could embolden other EU regulators to take a harder line on data-sharing practices that rely on SCCs or other legal mechanisms.
For Policymakers and Regulators
- Momentum for Stricter Enforcement: The ruling comes at a time when European regulators are increasingly focused on enforcing GDPR. In 2025, the European Data Protection Board (EDPB) issued new guidelines on consent mechanisms, emphasizing that pre-ticked boxes and bundled consent (where users must agree to multiple terms at once) are not compliant with GDPR. The Berlin court’s decision aligns with these guidelines and could serve as a blueprint for future rulings.
- Calls for Structural Reforms: The case has reignited debates about the need for structural reforms in how tech companies are regulated. Some lawmakers and privacy advocates argue that GDPR enforcement has been too slow and inconsistent, with fines often seen as a “cost of doing business” rather than a deterrent. The Berlin ruling may add pressure on the EU to adopt more stringent measures, such as breaking up tech monopolies or imposing stricter limits on data collection.
Meta’s Response and Next Steps
Meta has not yet publicly announced whether it will appeal the Berlin court’s decision. However, the company has a history of challenging similar rulings. In a statement provided to World Today Journal, a Meta spokesperson said:
“We are reviewing the court’s decision and will evaluate our next steps. WhatsApp remains committed to providing a secure and private messaging service, and we will continue to work with regulators to ensure our policies comply with local laws. We believe that our data-sharing practices are lawful and necessary to provide a seamless experience across our platforms.”
The spokesperson did not address whether Meta plans to modify WhatsApp’s data-sharing policies in response to the ruling. However, legal experts suggest that the company may need to implement significant changes to avoid further penalties. These could include:
- Decoupling WhatsApp Data from Meta’s Ecosystem: One potential solution is to create a technical barrier between WhatsApp’s data and Meta’s other platforms, such as Facebook and Instagram. This would prevent the automatic sharing of user data across services.
- Implementing Granular Consent Options: WhatsApp may need to redesign its consent mechanisms to allow users to opt out of specific data-sharing practices without losing access to the app. For example, users could be given the choice to share their contact lists with Meta or keep them private.
- Limiting Data Transfers Outside the EU: To comply with GDPR, Meta could be forced to store and process European user data within the EU, rather than transferring it to servers in the U.S. This would require significant investments in local data infrastructure.
The next legal milestone in this case will likely be Meta’s decision on whether to appeal. If the company chooses to challenge the ruling, the case could move to a higher court, such as the Kammergericht Berlin (Berlin Higher Regional Court) or even the European Court of Justice (ECJ). A final decision could take years, but the Berlin court’s ruling sets a strong precedent that other EU courts may follow.
What Users Can Do Now
Even as the legal battle plays out, users can take steps to protect their privacy on WhatsApp and other messaging apps:
- Review App Permissions: On both Android and iOS devices, users can review and revoke permissions granted to WhatsApp, such as access to contacts, photos, and location data. This can limit the amount of data the app collects.
- Opt Out of Data Sharing: WhatsApp’s settings include options to limit how much data is shared with Meta. Users can navigate to Settings > Account > Privacy to adjust their preferences, such as disabling read receipts or limiting who can see their profile information.
- Use Alternative Messaging Apps: For users concerned about data privacy, alternative messaging apps like Signal and Telegram offer end-to-end encryption and do not share user data with third parties. However, it’s important to note that Telegram’s default chats are not end-to-end encrypted, so users must enable “Secret Chats” for full privacy.
- Stay Informed About Policy Changes: WhatsApp and other apps frequently update their privacy policies. Users should read these updates carefully and consider whether they are comfortable with the changes. If not, they may choose to delete their accounts or switch to a different service.
The Bigger Picture: A Turning Point for Tech Regulation?
The Berlin court’s ruling is part of a broader trend of increasing regulatory scrutiny of tech giants, both in Europe and globally. Here are some key developments that could shape the future of data privacy:
1. The EU’s Digital Markets Act (DMA) and Digital Services Act (DSA)
The Digital Markets Act (DMA), which came into force in May 2023, aims to curb the power of “gatekeeper” platforms like Meta, Google, and Apple by imposing strict rules on data sharing, interoperability, and anti-competitive practices. Under the DMA, companies are prohibited from combining user data across different services without explicit consent—a provision that aligns closely with the Berlin court’s ruling. Meanwhile, the Digital Services Act (DSA), which took effect in February 2024, imposes additional transparency and accountability requirements on tech companies, including mandatory risk assessments for data practices.
2. Global Momentum for Privacy Laws
Europe is not alone in its push for stricter data privacy laws. In the U.S., several states have enacted their own privacy regulations, such as California’s Consumer Privacy Act (CCPA) and Virginia’s Consumer Data Protection Act (CDPA). At the federal level, lawmakers have introduced multiple bills aimed at creating a comprehensive national privacy law, though progress has been slow due to partisan disagreements. Meanwhile, countries like Brazil (LGPD), Canada (PIPEDA), and Japan (APPI) have implemented GDPR-inspired privacy frameworks, signaling a global shift toward stronger data protections.
3. The Future of Data Transfers
The legal uncertainty surrounding data transfers between the EU and U.S. Remains a major challenge for tech companies. The Schrems II ruling by the ECJ in 2020 invalidated the EU-U.S. Privacy Shield, a framework that previously allowed companies to transfer data across the Atlantic. While the EU and U.S. Reached a new agreement in 2023—the EU-U.S. Data Privacy Framework—privacy advocates have criticized it as insufficient, and legal challenges are expected. The Berlin court’s decision adds to the pressure on policymakers to find a lasting solution that balances privacy rights with the needs of global commerce.
