how can i use smath in my cloud project? do not get smath source code , use executable file can do it ?

Hello. It is not possible. The only legal way is to use iframe with a https://smath.com/cloud as a source.

I know what you're thinking. However, visiting foreign websites in China is sometimes interrupted, and this will make my project have uncontrollable risks. Just give me the executable file if you can. No source code is required.
If not, I will develop my own online computing application based on markdown. Don't need so many complicated functions.
Thank you very much for your product.

There's no prejudice, there is a legal agreement about the use of web version, hence you can only use the version hosted here.
