A lawful basis allowing processing that is necessary for the legitimate interests of the controller or a third party, unless overridden by the rights and freedoms of the data subject. It requires a balancing assessment.

Related: Lawful Basis, Legitimate Interests Assessment, Purpose Limitation
Legitimate Interests Assessment

A documented three-part test covering the identification of a legitimate interest, the necessity of processing to achieve it, and a balancing of that interest against the individual's rights and reasonable expectations.

Related: Legitimate Interests, Data Protection Impact Assessment
Purpose Limitation

A core principle requiring that personal data be collected for specified, explicit, and legitimate purposes and not further processed in a manner incompatible with those purposes. Compatibility assessment governs reuse.

Related: Data Minimization, Lawful Basis
Data Minimization

The principle that personal data must be adequate, relevant, and limited to what is necessary in relation to the purposes for which it is processed. It discourages collecting data that may be useful later.

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

The principle that personal data should be kept in identifiable form no longer than necessary for the stated purposes. It requires defined retention periods and mechanisms for deletion or anonymization.

Related: Data Minimization, Anonymization, Data Subject Rights
Special Category Data

Sensitive personal data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, genetic or biometric data, health data, or data concerning sex life and sexual orientation, subject to stricter conditions.

Related: Personal Data, Lawful Basis
Data Subject Rights

The set of entitlements individuals hold over their personal data, typically including access, rectification, erasure, restriction, portability, objection, and rights concerning automated decision-making. Requests must be handled within statutory timeframes.

Related: Subject Access Request, Right to Erasure, Data Portability
Subject Access Request

A data subject's request to obtain confirmation of whether their data is processed and to receive a copy of that data along with information about purposes, recipients, retention, and rights. Usually subject to a one-month deadline.

Related: Data Subject Rights, Redaction
Right to Erasure

Also called the right to be forgotten, it allows individuals to request deletion of personal data where grounds apply, such as withdrawal of consent or unlawful processing, subject to legal retention exceptions.

Related: Data Subject Rights, Storage Limitation
Data Portability

The right to receive personal data in a structured, commonly used, machine-readable format and to transmit it to another controller, applicable where processing is based on consent or contract and is automated.

Related: Data Subject Rights, Consent
Redaction

The process of obscuring or removing information, such as third-party data or privileged material, from documents before disclosure, for example in response to a subject access request.

Related: Subject Access Request
Consent Management Platform

A tool that captures, records, and enforces user consent choices across channels and systems, enabling granular preferences, proof of consent, and propagation of withdrawals to downstream processing systems.

Related: Consent, Withdrawal of Consent
Accountability

The principle requiring organizations to take responsibility for compliance and to be able to demonstrate it through policies, records, training, assessments, and other documented evidence of appropriate measures.

Related: Privacy Governance, Records of Processing Activities, Data Protection Officer
Privacy Governance

The organizational structure of roles, policies, procedures, and oversight mechanisms that direct how personal data is managed, ensuring responsibility is assigned, decisions are documented, and compliance is monitored.

Related: Accountability, Data Protection Officer, Privacy by Design
Data Protection Officer

A designated individual tasked with informing and advising on compliance, monitoring data protection performance, and acting as a contact point for regulators and data subjects. Independence is essential to the role.

Related: Accountability, Privacy Governance, Supervisory Authority
Records of Processing Activities

An inventory documenting each processing operation, including purposes, categories of data and data subjects, recipients, transfers, retention periods, and security measures. It supports accountability and oversight.

Related: Accountability, Data Protection Impact Assessment
Privacy by Design

An approach embedding privacy protections into systems and processes from the outset, including default settings that minimize data collection and exposure, rather than retrofitting compliance after implementation.

Related: Data Minimization, Data Protection Impact Assessment
Data Protection Impact Assessment

A structured assessment required for processing likely to result in high risk to individuals, such as large-scale monitoring or sensitive data use. It describes the processing, assesses necessity and risks, and identifies mitigations.

Risk Assessment

The process of identifying threats to personal data, estimating likelihood and severity of harm to individuals, and evaluating whether existing controls reduce risk to an acceptable level before processing begins.

Related: Data Protection Impact Assessment, Residual Risk, Risk Treatment
Residual Risk

The level of risk remaining after mitigation measures have been applied. It must be evaluated against acceptance criteria and may require escalation or prior consultation with a supervisory authority.

Related: Risk Assessment, Risk Treatment, Prior Consultation
Risk Treatment

The selection and application of controls to modify risk, such as avoiding, reducing, transferring, or accepting it. Measures should be proportionate to the sensitivity and volume of data involved.

Related: Risk Assessment, Residual Risk
Prior Consultation

A process where the controller seeks advice from a supervisory authority before processing when a data protection impact assessment indicates residual high risk that cannot be sufficiently mitigated.
