- There's data-sharing agreements with more than just the N eyes countries
- If there's an international warrant for that data the company is obliged to comply regardless
The only countries in which n° 2 doesn't apply for the US are countries you really don't want your data in either.
In short, however: if a government really wants your data it will find a way to get it no matter where you store that data, so the best thing is to simply not store that data at all, Mullvad and Signal don't do that.
