Refactor lib for better readability

**Feature request**
It would be great to have export for store.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_export` with default `false`.

The issue names no files, tests, or entry points. Start by locating the configuration handling and store implementation, then trace how production deployments persist or expose store data. Done means the export behavior is controlled by enable_export, which defaults to false, with the expected behavior covered or verified.
