Website tracking activity

wow, very helpful thank you. In essence, if I have a chrome broswer open, can a website see what I am doing simultaneously on my computer harddrive, for example in a preview window, or a word document?

having been specifically instructed by the website in question to "open only on chrome, with no add-ons installed" it's a fair assumption there's a plan to monitor what I'm doing offline while using this website. Very interesting (and disconcerting).

This is my quandry. I must fill in a questionnaire for work online through a survey website. The company specifically told us to install chrome with no addons, "as the survey will only work on this broswer setup", but the cynic in me finds it strange that something "anonymised" cannot tell me if the survey (to be taken over multiple hours) can track/click-log/monitor what i do in a different browser window, or programme on my personal machine. I'm not a conspiracy theorist by any means, just becoming increasingly data security conscious following some close calls! In essence, I guess there has to be a difference between what the broswer knows/records, versus what the website does (although the website has a tiny disclaimer saying "personal data will be collected, processed, and saved according to arti.28 EU GDPR. Both the oragnisation and survey company are diligently following all technical and organisational measures for the secure and earmarked processing of your data")

Thank you all for your replies

Good suggestion, thank you
