>The app is local by default. [...] Being local also means no liability. Personal immigration history is exactly the kind of data governments might want.

That doesn't seem to be a great argument in favour of crossing borders with this information stored locally on your device.

>Keeping it off my servers means nobody can demand I hand it over.

I'm not a lawyer, but I believe that this is completely false.

[Edit] On second reading, I realise that he's just talking about him not being able to hand over the data. This is true. But the user can be forced to hand it over. So I retract that it's completely false, but it's still a very bad idea.

If I was concerned about this sort of thing when travelling, the only sensitive thing I would carry is a password in my head that grants me access to end-to-end encrypted data on some server.
