Privacy
Holographic Extreme Cache does not collect analytics, does not track visitors and does not send site data to a third-party service.
The plugin stores cache files, configuration helper files and optional log files inside its own folder under the WordPress uploads directory. Logging is off by default.
Uninstall
The plugin can remove its settings, cache files, configuration files, log files and scheduled events on uninstall if the uninstall cleanup option is enabled before uninstalling.
If uninstall cleanup is not enabled, settings and generated files are left in place so the site owner can remove or inspect them manually.
