Cancel or confirm deleted document from Compress PDF Online

Hei,
I was compressing a document at Adobe Compress PDF Online  ( https://www.adobe.com/acrobat/online/compress-pdf.html ).
I wasn't user when I was using the service so I don't know how to confirm that the document was not upload in the cloud. I tried to cancel it because it was a document for personal use (a random collection of pictures from Internet as graphic research) but I'm not sure if it was cancel. I didn't get the final compressed file in my computer so I thought it was OK cancelled. But I'm not completely sure because the browser got frozen.   
My prime intention is not to get in troubles with the policy because the pictures where from different places from Internet and it was for personal use not for to publish it.

I felt a bit concerned so I contacted Consumer Services and they didn't find nothing problematic but they recommend to me to publish a query here if someone can help to me. 
I would appreciate if someone can help to me or tell me more about how to resolve this in case it would be a problem. Thank you very much for your time and have a nice day!
