Posteo supports PGP encryption with a PGP key you have when an email comes into your inbox, which then can be decrypted by your client. So it is doable.

Yet not great from a privacy perspective. They don’t even allow third party email apps.

KDE Plasma just keeps getting better every single week.

So XMPP?

“functions on android”

You can download the website’s static files then (html, css, images, etc.) but features such as search won’t function if it works by querying some database.

Iirc most browsers have a way to make website’s available offline. I know chromium has it, but firefox does not. You’d probably need an extension for that. Or you can download the static files, store them in a directory manually and then open the index.html with firefox. That should work.

Would you be ok with reading wikipedia?

There’s this app that is for viewing wikipedia pages both online and offline: https://f-droid.org/packages/org.nsh07.wikireader/

To answer your edit: No. They use different encryption algorithms.

Whatever your goal is, there most likely is no such instance that satisfies your definition of “freedom of speech”. You should run your own instance where you have full control. Since most instances wouldn’t federate with such an instance, a relatively cheap VPS will do. Even some old computer you may have lying around.

Mastodon*

I tried using yunohost and some others but they all sucked. I went with just using the bare podman cli

I agree. Revolt is a good alternative to Discord. Matrix does not feel the same as Discord, but just a WhatsApp alternative that is decentralized and federated.

You do have a good point. However, I can’t consider a proprietary operating system like iOS truly private. It may be secure (certainly more so than stock Android and some random custom Android based ones) but if I can’t be sure that my operating system isn’t spying on me, then security alone doesn’t matter much for me tbh. Apple’s operating systems are no exception to this.

So, in a ranking that considers both security AND privacy, iOS being the second one is questionable. However, if the ranking is based solely on security, then I have no issue with it.

So more security equals more privacy? Is that why iOS is second in your rankings?

Revolut is an option. And hopefully soon we’ll also get GNU Taler, which isn’t exactly a virtual card system, but is a private payment system. The customer is kept anonymous while the seller’s income is transparent.

No, doesn’t seem so.

Yep. If you don’t want anyone else, just close the registrations.

I’m pretty sure you implied that the ranking was based on security and privacy. I don’t see the privacy benefits of using iOS over a custom privacy OS.

LW’s user base accounts for about 36.4% (as of writing this) of all Lemmy users (spread across approximately 570 instances according to FediDB), which is too large.

You will occassionally see some people from other platforms, like mastodon, commenting or posting here. But Lemmy isn’t the most compatible one, so you probably won’t see microblogs and such. If you want to see microblogs as well, use mbin (kbin fork). It is a mix of Lemmy and Mastodon. You can micro blog and comment on magazines (communities in the mbin/kbin platform) that way.

I especially am thinking of self hosting mbin because I do want to see some microblogs from some users.

Also I welcome you to Lemmy and the Fediverse. Good thing you didn’t choose lemmy.world or lemmy.ml
