how to change creator's GUI language?

Greetings

It seems that zoho creator detects your region and sets the GUI language to that automatically..first of all this is just a bad idea, let users choose their preferred language or just import GUI language from user's account settings. my GUI is stuck in arabic language, most translations are outright wrong/unclear and the RTL direction is just not supported that well, it's just frustrating..i have no way to change the language or i just can't find where i can do that..

can someone guide me to where i can change the creator's GUI language? 

Thanks
