If I upload a paper to Scholarcy could I be violating copyright?

No. Scholarcy does not distribute any original papers or the summaries of these papers.

When it comes to copyright, think of Scholarcy as the same as any reference management tool, Google Drive or Dropbox. The paper is uploaded to the user’s personal account for their personal use for research purposes. And we go one step further – the original paper is not stored. It is summarised and the original PDF is deleted. There is no way for anyone else to access the paper.
