Every figure is calculated from a named source or from what you enter: the time zone database, a published exchange-rate feed, airport coordinates, public-health guidance. None of it is a price or a timetable.
02In your browser
The tools run on your device and send nothing you type to us. The packing list, the budget and the places in the world clock are kept in this browser only, so they are there when you come back.
03Honest about limits
Each page ends with what its tool cannot know. Where a rule changes often, such as entry requirements, we link the official source and our visa desk rather than stating it.
