Uploading the tool made on infinityfree to Play store legal?

No, the website is not being used as permanent file hosting. The uploaded file is only processed temporarily — for example, converted into a PDF — and then the user downloads it immediately. After the download, the file is automatically deleted from paths like example.com/files/example, so no long-term storage is provided.(it’s the idea)

The main question is whether this type of temporary file-processing website can be uploaded to the Google Play Store as an Android app, since there are many tutorials showing how to convert a website into an app and publish it on the Play Store, Is this legal according to terms of service of infinityfree?
