This module sanitizes Personal Identifiable Information in the database, which is useful for developers who want to run the site locally without putting any user data at risk.
The advantage of this approach over other sanitization projects outside of Drupal is that we can use Drupal functions to dynamically figure out the tables and fields where these field types are stored. If you add a new telephone field, no need to change any configuration for this module; it will be sanitized automatically!
