The right to receive personal data in a structured, commonly used, machine-readable format and to transmit it to another controller, supporting competition and individual control.

Related: Data Subject Rights, Data Subject Access Request
Purpose Limitation

A principle requiring that personal data be collected for specified, explicit, and legitimate purposes and not further processed in ways incompatible with those original purposes.

Related: Data Minimization, Lawful Basis, Storage Limitation
Data Minimization

The principle that personal data collected and processed should be adequate, relevant, and limited to what is necessary for the stated purpose, reducing risk and compliance burden.

Related: Purpose Limitation, Storage Limitation, Privacy by Design
Storage Limitation

A principle requiring that identifiable personal data be kept no longer than necessary for the purposes of processing, with defined retention periods and deletion or anonymization afterwards.

Related: Retention Period, Data Minimization, Anonymization
Retention Period

The defined length of time personal data is kept before deletion or anonymization, set by legal requirements, business need, or the purpose of processing and documented in a retention schedule.

Related: Storage Limitation, Anonymization
Accountability

The principle that an organization must be able to demonstrate compliance with privacy obligations, through policies, records, assessments, training, and evidence of controls, not merely claim adherence.

Related: Privacy Program, Records of Processing Activities, Data Protection Impact Assessment
Privacy by Design

An approach embedding privacy protections into systems, processes, and products from the outset, including default settings that limit data collection and sharing without user action.

Related: Privacy by Default, Data Minimization, Data Protection Impact Assessment
Privacy by Default

The requirement that, without user intervention, the most privacy-protective settings apply, so only necessary personal data is processed and shared by default.

Related: Privacy by Design, Data Minimization
Data Protection Impact Assessment

A structured risk assessment required before processing likely to result in high risk, such as large-scale profiling or sensitive data handling, documenting risks and mitigating measures.

Related: Accountability, Privacy by Design, Risk Assessment
Records of Processing Activities

An inventory documenting what personal data an organization processes, why, where, who receives it, and how long it is kept, supporting accountability and regulatory inquiries.

Related: Accountability, Data Mapping, Retention Period
Data Mapping

The practice of tracing personal data flows across systems, teams, and third parties to build an accurate picture of collection, storage, sharing, and transfer, forming the basis for many compliance activities.

Related: Records of Processing Activities, Data Processing Agreement
Data Protection Officer

An independent role responsible for monitoring privacy compliance, advising on obligations, and acting as a contact point for regulators and data subjects. Required in some jurisdictions under specified conditions.

Related: Supervisory Authority, Accountability
