The right to data portability is a GDPR right under Article 20 that allows individuals to receive a copy of their personal data in a structured, commonly used, machine-readable format — and to transmit that data to another organization. The right applies when processing is based on consent or contract, and the processing is carried out by automated means. It enables users to switch between services without losing their data. Organizations must respond to portability requests within one month. The right does not apply to data processed under legitimate interests, legal obligation, or other non-consent legal bases.
