Clears or anonymizes fields with user identifiable data and additionally deletes all files if you selected a file field
Anonymize fields in ProcessWire
This module allows you to select fields that get anonymized after a defined period of time.
Anonymization refers to either replacing field values with a configurable fill word, or removing stored data altogether. The time period after which page content gets anonymized can be configured (default is 60 days), and anonymized fields can be selected manually via module config screen.
Behind the scenes LazyCron is used to trigger the anonymization process, which makes the whole process completely automatic.
