Data portability is a principle and right in data protection and privacy regulations that empowers individuals to obtain and reuse their personal data across different services or platforms. The concept is designed to enhance individuals' control over their own information and foster competition and innovation by allowing users to transfer their data seamlessly between various online services.

Key elements of data portability include:

User Control: Data portability grants individuals greater control over their personal data by enabling them to access, retrieve, and transfer their information from one service provider to another.

Interoperability: The principle encourages interoperability between different platforms and services, allowing users to move their data easily without encountering technical barriers or compatibility issues.

Data Formats: Service providers are typically required to provide personal data in a structured, commonly used, and machine-readable format, facilitating smooth transfer and integration with other services.

Consent and Transparency: Organizations must inform individuals about their right to data portability, and data transfers should occur with the individual's explicit consent.

Data portability is often enshrined in data protection laws to empower individuals and promote a more user-centric approach to data management. It contributes to a more competitive and dynamic digital environment by giving individuals the freedom to choose services that best suit their needs without the fear of losing control over their personal information.
