GDPR Article 25 — Data Protection by Design

Article 25 of the GDPR obliges controllers to take data protection principles such as data minimization into account already when developing technical systems — known as data protection by design (Privacy by Design). In addition, default settings must ensure that personal data is only processed to the extent necessary for the respective purpose (Privacy by Default).

Privacy by Design means concretely: technical systems must be designed so that they limit the processing of personal data to the necessary minimum. Appropriate technical and organizational measures must be taken that are designed to effectively implement the GDPR principles. These include pseudonymization, data minimization, transparency, and the ability for data subjects to exercise their rights.

Datenmaske consistently implements Privacy by Design: all data processing takes place on EU servers, documents are automatically deleted after a configurable period, no external AI services are used, and the redaction log grants full transparency over all actions performed. The default settings are chosen so that data protection is maximal — not minimal.
