Hello @ahmash ,

i recommend you use some static security features like RDP (read out protection ) you will find a detailed description on AN5156 section 6.2 and you can have a look on our mooc videos on this feature in this link .

Hope this will answer you inquiry.

    Enable RDP and have your own loader capable.of IAP (In App Programming) to upgrade your application, ideally using encryption if the update is to be distributed.

      Hi @ahmash ,

      user @Tesla DeLorean is right. More about the IAP can be found for example here:
