Removing wp_options entries

Hi, just one question. I don’t have your plugin, but, while cleaning my website db, I found many entries in my wp_options table (with autoload=’yes’) and I’m here to ask if they are from your plugin (even if I don’t remember having installed it, from the ids I can infer they are really old):

wauc_admin_bar_menu_setting
wauc_admin_general_setting
wauc_dashboard_setting
wauc_regist_dashboard_metabox
wauc_regist_metabox
wauc_sidemenu_setting
wauc_site_setting
wauc_user_role_setting

If they are from your plugin and I don’t use it, may I safely remove them?

Thanks
