Exactly my question too, thank you for looking into it. A lot of businesses are getting fined in my country, and I can't find a way to disable google font in simpli template.
SOLUTION
Sat down with a talented webdev and pondered for two hours.
Imported fonts on the server, inserted custom.css all fine but site still loads from google server
to cut the ties
In the ja_simpli folder check out file helper.php
For my installation (V1.0.0 + Joomla ) it's in Line 376
/**
* Add custom style css
*/
public function addCustomStyle () {
$html = '';
$google_fonts = preg_split('/\n/', $this->getParam('styleGoogleFonts'));
foreach ($google_fonts as $font) {
$font = trim($font);
if(!$font) continue;
// $html .= '<link href="https://fonts.googleapis.com/css?family=' . ($font) . '" rel="stylesheet" type="text/css" >' . "\n";
}
Comment out the line $html .= '<link href="https://fonts.googleapis.com/css?family=' . ($font) . '" rel="stylesheet" type="text/css" >' . "\n";
with // and google fonts no longer load.
