Data retention
Data retention refers to all obligations on the part of controllers to retain personal data for certain purposes. Some regulations and directives impose a certain data retention period.
The Data Retention Directive (Directive 2006/24/EC) contains an obligation for providers of electronic communications to retain traffic and location data of communications through telephone, e-mail, etc. The retention takes place for the purpose of the investigation, detection and prosecution of serious crime.
As for clinical trials, a data retention period of at least 25 years was fixed in article 58 of Regulation (EU) 536/2014.
