The local customization ruleset for a user is the ruleset identified for local customization in the Settings tab of a user's access group form.
For developers (or other users who create rules), this is a ruleset that normally has at least one associated version that is not locked.
When you use the Save As toolbar button to copy an existing rule, the local customization ruleset is often the default value for the ruleset of the new rule.
This ruleset is always included in your set of application rulesets — those that appear in the Application Explorer.
