It is not fully private. You can browse without an account but cant use the site’s search. If you don’t want to create an account you can use a search engine like duckduckgo like adding site:rutracker.org to your query
You can find games like this one in rutracker which require no installation, decompression or dwarfs thing, only the files. Just like what you’d have after installing a repack
I have been using my poco f1 for more than 4 years now, the only problem i have had is the battery. It has an sdcard slot, headphone jack, 6gb of ram which has been more than enough and latest lineageos is supported. see fsfe.org/activities/…/index.en.html
