The data stay with the source

The terms of Yahoo Finance allow personal use only. A published study does not pass these data on: publishing asks the researcher to confirm the terms, and the study's code loads the data again from the source (get_data.py). A reader who asks the authors for the data is sent to the source.

Terms of use for the data

Yahoo's terms of use apply. The yfinance project notes that Yahoo's finance data are intended for personal use only; yfinance is not affiliated with Yahoo.
