First, a big thank you for your great service!
According to your Terms of Service, free plans include a generous 100 GB of storage as long as it is not used “as a remote storage server only”.
I have developed an application for an art project that is currently hosted on a dedicated server (here). This app generates PDF posters on-demand from text and image data pulled in real time from third-party sites (e-commerce, social media, etc). Data is stored in a MongoDB database for later use, so that a poster can be retrieved with a permalink.
The app has been running for several years now and has accumulated a very large number of poster data. It currently stores about 1.5 million text snippets and 800 thousand images, for a total DB size of 15 GB.
Now we want to archive the app and turn it into a (mostly) static web site with historic data only and no way to pull new data. Your free plan offers more than enough storage space for the whole data. However I want to make sure that uploading such a large number of files is 1. technically possible, and 2. compatible with your terms of service, as these files are an essential part of the application.
Thanks for your clarification.
