Chrome queries

I suspect that I should be asking these questions on a different forum. On my Rpi4 running Raspbian Buster I use Chrome as my browser for those occasions when NetSurf in RISC OS is not up to it. Chrome keeps asking me for my Google account, and I am unwilling to open one. I am slightly allergic to storing data in the cloud. Broadband is still comparatively slow in my village, and I feel much happier storing my data on something that I can wield a hammer on. I note that Chrome looks for settings and resources at URLs beginning chrome:, which I presume to be an expression decoded by Chrome to a URL in the cloud. Is that correct? Is there any way in which I could get chromium: to be decoded to a URL in my home directory? If Firefox were available for Raspbian I would use that instead.

For help on what the chrome: URLs do, type this: chrome://chrome-urls/
