What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Can you please describe what you meant by "transfer mechanism"? If you meant what we do with the files, the files are first received by JotForm's servers. As soon as the files are received and submission is completed, we send those files to the integrated services - such as Google Drive - and we do so over SSL encrypted data connection.
Should you need further clarifications, please describe your question in greater detail, and we'll be glad to help. Thank you.
