With the GDPR deadline looming, it is an excellent time for WordPress plugin developers to finish adding or updating that often skipped, often neglected plugin uninstall code – you know, the “clean-up” code that deletes options and meta data and tables that the plugin added to the site?
Here’s the Plugin Handbook page you’re looking for: https://developer.wordpress.org/plugins/the-basics/uninstall-methods/
Tick tock. The GDPR takes effect on May 25, 2018.
There are, of course, other aspects of the GDPR that apply to the way plugins handle personal data or expose site visitors to data collection by 3rd parties, and solutions to those are coming in WordPress core (see below), but this area (data clean-up on plugin deletion) is one area that developers can attend to now if they haven’t already.
