Hi and welcome!
Thanks for using Google Translator to post. :)
SharePoint Online (Office 365) supports the sandbox code service for InfoPath forms if you have the E3 or an equivalent plan. You will need to be a site collection admin to publish.
There are some code features that will require admin approval. Basically anything that requires heightened level of permission.
Microsoft does have tools that you can run to determine if your form has a heightened level of security requirement.
Please let us know if you need additional help.
Good luck!
