Of course it doesn't work on ios. The issue you linked explains that a syncthing ios implementation would be useless because the background process can't run and the way filesystem access is managed makes the whole thing more or less pointless. It's available on all better operating systems though: Windows, macos, gnu/linux, android/linux, I think even chromebooks can run it?

Like I said, it's probably not a solution for many. A second database with shared secret is very straightforward and transparent way that anyone can grasp I think. It would definitely pass the family test for me.
that's on Apple, not on Syncthing. Guess what, when you lock down your devices so much they can't perform many useful functions. Next time, just get a phone you can actually own.
You can erase Google's OS on the Pixel phone fairly easily and replace it with your favorite ROM. In fact one of the reasons I switched to Android is adblocking. I can't stand the amount of ads I had to see on iOS, especially from apps like youtube or even the app store itself.
> it's also possible to set multiple different gpg keys for a specific directory. I don't think the last option is doable for most people though.
