Also I think this is a problem with both ios and android too?
I can't find any info relating to this, but we at least know apps can read your clipboard on Android as well, though they have to be on the foreground:
Limited access to clipboard data
Unless your app is the default input method editor (IME) or is the app that currently has focus, your app cannot access clipboard data on Android 10 or higher.
One thing to note is that there hasn't been any evidence of the clipboard data being sent anywhere (there are legitimate use cases for reading your clipboard data), so this
might not be as big as issue as it initially seems. It's better to be safe than sorry though. Either way, it's never proper to copy paste seeds/private keys anyway -- all you should be copying them on is a piece of paper.
Why is this on Speculation by the way? Lol.
