I’ve always been very private oriented: I started using linux-debian 20 years ago after discarding windows and apple. I rarely buy online but when I did, to be as private as possible I used to create an account using fake data by the e commerce platform I wanted, get my order and then ignore the account until I wanted yo use it again. Most of the times I used a vpn.
This worked till the platform banned me.
Now I’m thinking about investing in ETFs to build some capital for my retirement and platforms recommended to me like trade republic or scalable capital seem to be exclusively smartphone reliant. I wouldn’t use fake data to create accounts here, nor would it be possible (bank data involved).
The trouble with smartphones: I don’t want to be that guy changing smartphones every 2 or even 4 or 8 years. Spending $200 to $800 for a phone for such a short period of time is just a dumb idea, but I don’t know if it would be safe to use my 2018 android 8 smartphone to invest in ETFs. This 2018 model is my first smartphone. It’s a second hand one somebody gave me because he thought I really needed it. I would have never bought a new smartphone on my own. However, unsupported models are not secure for investing and this model stopped being supported years ago.
Another trouble I see: to use scalable capital or trade republic I’d have to download their app in my smartphone. Google is a company I don’t trust. Each time I needed to use something from their app database I got it using aurora, but I’m afraid scalable capital will automatically ban me if I download their app from f-droid instead of doing it officially using google. Using google to create an account would mean giving them my real data, because otherwise I risk being labeled a scammer. Correct me if wrong.
I’d love to invest using only a browser on a desktop.


What are you trying to hide, and who are you hiding it from?
I dislike that some privacy forums, like reddit and therefore here by proxy, have a cultural habit of talking about privacy or security as an abstract value in itself. But when we start getting into more detailed questions, it’s all vague and vibes until we make it clear who we’re trying to hide from and what we’re hiding.
For example, most of the time I’m not hiding from my own government. Sure, I incidentally do make it a bit harder for them to track me, but I’m more focused on hiding from Meta/Alphabet/Amazon/etc. (plus from a small group of deranged online stalkers obsessed with some of my friends) so there are plenty of online services and stores I can buy from without taking inconvenient measures. It’s fine for me if some services can guess my name and know where I live and one of my phone numbers. It’s not fine if they learn some other details.
It’s important to get out of the habit of saying “more private”, “less private”, “most secure”, and talk about what you’re specifically concerned with and how tactics and tools specifically address that. What information will Google gain from knowing your investments? Is that a threat to you? Are there acceptable ways to mitigate that threat?
I’ve been surprised how easy it was for me to make a fake Google account with no links to my real identity. I only use it for age-restricted YouTube videos, I wouldn’t trust it with money like investments, because the way I set it up is inherently suspicious and I wouldn’t be able to verify identity if challenged.
