Your Right to Data Portability
As a data subject you have the right to request that the data controller gives you your personal data so you can move it to another controller. You can think of it as roughly similar to your ability to ask your mobile network operator to port your number to another network.
The data should be provided to you as a file with your information in a structured, commonly used and machine-readable format. If technically feasible you can also ask one data controller to directly transfer your personal data to another.
This right is set out in Article 20 of the GDPR. The full text of the article is at the bottom of this page.
Real world example: In December 2019 Facebook announced a Photo Transfer tool which allows Facebook users to transfer their photos to another online service, should they wish to. This is data portability.
