Is there any privacy-friendly way to use Facebook on iOS? (reddrefuge.com)

First and foremost, I'll get this out of the way: I abhor all commercial social media. I don't trust them, I know users are the product, and - ultimately, I feel they're nothing but a cancer on society.

But, I also have to acknowledge that, for one or two use cases at least, they seem pretty unavoidable.

For me, that one use case is Facebook Marketplace. Here in Australia, there's simply no better alternative if you want to reach a large number of potentially interested buyers (or even buy some stuff yourself). The supermarket noticeboard is no more; the Trading Post was bought long ago and died on the vine; and Gumtree has devolved into a cesspool of nothing but scammers and fuckwits.

So, I use FB Marketplace. My FB account isn't in my name, uses a throwaway email address, and has no followers or friends. It's only a member of the local buy/sell groups that I'm interested in, and it performs no "social" activities (posts, likes, etc) at all.

Until now, I generally only use FB marketplace with a "clean", dedicated browser on my computer, running in private mode and via a VPN. But, it means I frequently miss messages from interested parties when I'm away from my computer.

I also sometimes use the mbasic.facebook.com site from a private Firefox tab on my iPhone, but FB has just started telling me I need to use Chrome (no. fucking. way.) or Safari (maaaaaybeeeee?) after October 28th.

When I was on Android, there were a few wrapper apps that I was able to use but, so far, my searches for an equivalent on iOS have turned up nothing.

So, knowing full well this may lead to nowhere, I thought I'd ask this community: does anyone have a good, privacy-friendly way to use FB on iOS?

Thanks in advance for any useful tips or suggestions.

Mate, I appreciate the effort you took to write your response, but I get the distinct impression you didn't go past the title of my post before responding.

As I said, I'm only seeking to use FB marketplace to buy and sell - nothing more. Nothing social. No friends or followers.

I thought I'd made clear the lengths I've already gone to, to maintain my privacy when using FB on my personal computer, so I'm just looking to understand if the same is possible with iOS when on the move. That's all.

In that case, you probably have to:

Use Tor respectively Tor Browser (without any additional extensions, and set the default security level to "Safer" if possible with Facebook) to create a completely new, anonymous account on Facebook. Don't enter any data there that could be linked to your person, e.g. no real mail address (use an alias, ideally a completely new one), no real names, no real data, also no real billing or delivery address. Literally nothing that could be linked to your person. Only ever use Facebook's site within the Tor Browser, to ensure that your real IP address and browser data aren't leaked. Never use their apps, never use your regular browser for it, also don't use PWAs because that's similar to using a regular browser, which reveals your real current IP address to the site. Unless you use a VPN to have a different IP, but you'd have to minimize your VPN usage just for that app interaction. If you continue to use the same VPN IP for other stuff as well, you could de-anonymize yourself later on. Mullvad or Proton are commonly regarded as good choices for trustworthy VPNs which don't log or sell any user data, or at least there are no known cases for it (yet).
Don't add any friends on the site, try to limit your interactions with the site so that it can't create a big psychological profile from you and try to link that behavioral data to existing persons (the more you use the site the easier this method might become for them). Behave slightly differently than you would normally.
When you buy something, remember that you'd have to conceal your real delivery and billing data/addresses as well. Which is hard to do when you actually want to buy and receive something. Your payment data and/or address data can EASILY and instantly de-anonymize you, also in front of Facebook. So my suggestion for something still practical would be to have a relative or friend buy it after you arrange that with them, have it delivered to their address, and you pay them for it and gather it from their place. So in essence you need a proxy person to do the receiving and paying for you. If you want to sell something, that's more inconvenient of course, but you'd also have to do it similarly.

The most problematic de-anonymizing data about you is going to be your real current IP address (which is revealed when you use a regular browser, PWA or their app, all with a non-VPN or non-Tor IP address) as well as billing or address data. In case you're using their app, they'll be able to gather even more data to de-anonymize you more easily.
