I'm working on an application that is completely built upon user interaction. In my application logs, I log each interaction and print the email address to uniquely identify which user did which interaction.
This application log will not be visible to anyone other than:
- Me
- The next owner of the application if I would sell the project
- An administrator I might hire if the workload get'sgets too big
An example of a log record is something like this:
2019-01-24 14:27:20.954 INFO 32256 --- [whatever-info] s.p.s.t.d.m.s.SomeClassThatPrintsTheLog : Registering user with email address [email protected].
Is this allowed under GDPR or should I mask the printed email address in any way? Or use another solution?
