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.

“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.

No, of course I don’t. I am not as paranoid as Richard Stallman, but I am also not as pronoid as the average human to just use proprietary software when there are similarly functioning open source software. With open source software, you can inspect the code and compile the code that you inspected. This is not true for something like iOS.

And of course, FOSS malware also exists (for example the recent xz data compression program). But guess what? You can find if it is really malware or not because you ultimately can inspect the code and compile the code you inspected. That is also why the malware in xz was found out. Who knows what there is in closed source software you can’t inspect the code of. Do you perhaps believe in security through obscurity?

Using open source software is always an advantage. Praise for privacy software should be earned through the ability to verify them, and not granted by default.

I don’t know about you but if I don’t know what a program that I can’t inspect the code of does, I’ll just assume the worst case scenario. I can’t prove it but you also can’t prove that it isn’t doing something shady, can you? So what if I am using Private Relay? Apple will know what websites I visit or what I do with my phone as long as I use their proprietary operating system and who knows who they’ll give it to. And with this, I am saying it again: Apple’s operating systems are no exception to this rule.

sigh

My evidence is something being proprietary and in the hands of big tech (in this case Apple). What makes you blindly trust in Apple’s words?

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 said that the ranking was based on security and privacy. I don’t see the privacy benefits of using iOS over a custom privacy OS.

I believe the official instance already got most of the people who would want to use Bluesky in it.

And even if people did start self hosting their own instances, I am not sure if they could handle the traffic.

I wonder if Bluesky will also be like that someday.

iOS second? What a joke.
