"Facebook verriegeln" is the best free tool for the modern introvert. It offers a sense of privacy that is 90% psychological and 10% technical. It doesn't stop Facebook from harvesting your data to sell you socks, but it does stop your boss from seeing your vacation photos while you’re supposedly "working from home."
The functionality is surprisingly satisfying. When a random acquaintance from high school or a stranger tries to click on my photos, they are met with a polite but firm message that this content is unavailable. It’s the only tool on the internet that allows you to say "No" to nosy people without actually having to speak to them.
