That is true, for real life it's harder but as for digital, again. Until I'm here I think my data are protected simply because I'm pretty often around my devices and when that won't be the case I would want it to stay that way.

To answer to your second reply, I do understand that evryone has their own secrets. I know that and I'm pretty sure that whatever secrets the people I know may have won't bother me. We all have our things that might appear weird, strange or wrong to others and that's common to everyone. But to me, if I applied that tought there would be no point in being into this foss and privacy movement at all. If I don't care about my friends knowing my secrets then why would I care that a computer does? I've spent the last copule years trying to find alternatives to companies like google and I tried finding trusted software while also minimizing the amount of data I have online (I have around 30 accounts compared to the 100+ I had when I started) so since I'm so invested in this I aim to improve as much as I can.

100% privacy won't be possble until the day I dig a hole on the bottom of the ocean to live in but for whatever can be done I aim to do it.

I'd sum up all this into something like I'm more of an "everything or nothing" kind of person when it comes to digital stuff, since I put effort into not using the convenient mainstream options, might as well always take it to an upper level.

When Bob is active part of what you don't want Alice to know, it doesn't matter whether you "tell" Bob or not, he knows.

You can try and hide it from him, add layers like an onion, but even that isn't necessarily a failproof guarantee that you left no trace, even onions can be peeled or holes pierced.
