        return $privacy_policy_strings;

}

I want to edit this text $string = __( 'I consent to having %s collect my personal data and use it for administrative purposes. For more info check our privacy policy where you\'ll get more info on where, how and why we store your data.', 'wp_gdpr' );
How can I do it since there are no hooks in the plugin? I thought maybe to extend the class, but I don’t know if it’s possible to edit an existing function.

I tried this and it’s not working.

use wp_gdpr_wc\controller\Controller_Menu_Page_Wc;
class test extends Controller_Menu_Page_Wc{
    public static function get_privacy_policy_strings() {
        $lang = new Gdpr_Language();
        $lang = $lang->get_language();

        $privacy_policy_text_woo_request = get_option( self::PRIVACY_POLICY_TEXT_WOO_REQUEST . $lang, null );
        $not_consent_woo_request         = get_option( self::NOT_CONSENT_WOO_REQUEST . $lang, null );

        if ( ! isset( $privacy_policy_text_woo_request ) ) {
            $string                           = __( 'I consent to having %s collect my personal data and use it for administrative purposes.
            For more info check our privacy policyss where you\'ll get more info on where, how and why we store your data.', 'wp_gdpr' );
            $blog_name                        = get_bloginfo( 'name' );
            $privacy_policy_text_data_request = sprintf( $string, $blog_name );
            update_option( self::PRIVACY_POLICY_TEXT_WOO_REQUEST . $lang, $privacy_policy_text_data_request );
        }

        if ( ! isset( $not_consent_woo_request ) ) {
            $string                  = __( 'The consent checkbox was not checked.', 'wp_gdpr' );
            $not_consent_woo_request = $string;
            update_option( self::NOT_CONSENT_WOO_REQUEST . $lang, $not_consent_woo_request );
        }

        $privacy_policy_strings = array(
            self::PRIVACY_POLICY_TEXT_WOO_REQUEST => $privacy_policy_text_woo_request,
            self::NOT_CONSENT_WOO_REQUEST         => $not_consent_woo_request
        );

        return $privacy_policy_strings;
    }
}

Edit: Fortunately I could edit that text from wp_options table in database, If someone has any idea how to do it from code, that would be useful for times!

There is a filter you can use, but it is well hidden. Take a look at the WordPress function __. As you can see it calls another function, translate. And there it is, a filter called gettext. You can use it to intercept any (translated) text that is run through __.

Basically, what you do is overwrite the translation, which will be the same as the original text if no translation is available for the current language. Like this:

add_filter ('gettext','wpse305425_change_string',10,3);
function wpse305425_change_string ($translation, $text, $domain) {
    if ($text == 'I consent to ...') $translation = 'your text';
    return $translation;
    }
