To be fair, that really depends what you use your PC for. Looking at youtube without a profile, and reddit and the news, playing music, offline games. You will be 100% fine. If you have to log into somewhere with sensitive data, don’t. But as a secondary device you PROBABLY will be fine. Requires significant discipline, to not accidentally log into facebook on it though.
See for exaple the fact wheter you ‘have’ to have facebook kinda locates you as an American. This is the issue with ‘sensitive’ data you may or may not know what it is.
