Hi,
Thank you for contacting us.
Unfortunately, Farsi translation is not available yet.
We do not translate in Persian, however, our plugin is ready for adding translations.
We would be very grateful if you complete the translation using WordPress system (https://translate.ww.wp.xz.cn/projects/wp-plugins/captcha), this is faster and more convenient way to update the translation.
Some info about the translation in WordPress:

Hi,
Unfortunately there’s a misunderstanding. By captcha language I mean the catcha itself (e.g: I’m not a robot) not the settings page. I also checked the plugin translation and found Farsi (captcha-fa_IR.mo , captcha-fa_IR.po) but I need the captcha itself to work in Farsi itself, like this:

Please explain how to do that.
Thanks for your response.
Hi,
Unfortunately, there is no possibility to add the translation for ReCaptcha manually.
We have Google Captcha (reCAPTCHA) Pro plugin – http://bestwebsoft.com/products/wordpress/plugins/google-captcha/ where you are able to choose the necessary ReCaptcha language, including Farsi (Persian).
Sincerely,
