Thank you for your message.
Please note that all Helix Framework templates, including the Pitech template, as well as SP Page Builder, load Font Awesome directly from your local server and not from external sources. This ensures that all icons, including Font Awesome, are served locally, complying with your requirements for local data usage.
If you are still experiencing issues or noticing Font Awesome being loaded externally, please let me know, and I will assist you in reviewing the configuration further.
Best regards
