The the copyright is located into {root}/plugins/system/falangdriver/falangdriver.php on line 61.
Code:

Work fine for me with Joomla 2.5.8 and Falang 1.1.7
Joomla3版本，Falang 2.0版本隐藏方法如下：
找到 plugins\system\falangdriver\falangdriver.php
大约在95－97行注释掉，如下：
//if ($version->_versiontype == 'free' ) {
//FalangManager::setBuffer();
//}
