Mart 31, 2026
Data protection is one of the most critical legal obligations for online businesses operating in Turkey. With the rapid growth of e-commerce, digital services, and online platforms, the collection and processing of personal data have become central to business operations. As a result, Turkish authorities have significantly strengthened data protection enforcement in 2026, introducing stricter monitoring mechanisms and higher penalties for violations.
For foreign businesses, compliance with data protection laws is not optional. Even companies without a physical presence in Turkey may be subject to regulation if they process the personal data of Turkish users. Improper data handling—such as collecting data without consent, failing to secure information, or transferring data unlawfully—can lead to serious legal consequences.
From a legal perspective, data protection obligations are closely linked with commercial law, and working with a commercial lawyer is essential to ensure compliance and minimize risks.
