Is It Ethical Or I Guess Allowed For Me To Use A Prior Data Set For Practice?

I think I already know the answer but want to get other opinions.

I have two large data sets that I had access to in the past: 1 was shared with me on Github and is still available on their profile – Its real data but redacted for HIPAA reasons.

Another Data set I had been given access to for during my Capstone project – Its also redacted and does not have any direct patient identifiers (Medical recor numbers but this means nothing to me or This is the only thing I’m worried about)

​

Would it be appropriate for me to re-use these data sets and put them up on my portfolio with data visualizations and as ‘data cleaning’ projects?

​

Any advice is appreciated
