A vault does not hide itself, and if you open it for an officer, it opens. Before a border check, the one thing you control is what the phone carries. This article gives no legal advice.
What Vault9 cannot do here
There is no decoy vault, no duress mode and no hidden second vault. A wrong pattern shows an error, not an empty vault.
We also cannot protect a vault that is open on an unlocked phone. What an officer may ask for, and what you must do, depends on the country. Ask a lawyer who knows the law of the country you enter. Ask also whether deleting data before the trip is wise in your case.
Decide what travels with you
A file that is not on the phone cannot be looked at on the phone. Open the vault once before you go and check that your files show. Think about photos, documents, chats and downloads, not only the Photos app.
If you plan to remove files or the app, make sure you can get them back. The iCloud backup is the only copy of the vault outside the iPhone. Open the Gallery first and check that it says All backed up to iCloud. Deleting the Vault9 app deletes the vault on that phone. Do it only after the backup is complete.
Leave the kit at home
To restore the vault on a phone later, you need the Emergency Kit with the Secret Key. If your pattern is written on it, anyone who has the kit and a copy of your files can open the vault. So the kit travels badly. Keep it at home, like a passport, and work out how you can reach it from abroad. Run the kit test in Settings before you go, to check that the kit still matches.
Check iCloud Photos before you delete
If you delete photos in Photos to travel light, look at your settings first. With iCloud Photos on, Apple says a deletion on one device also deletes the photo on your other devices with the same Apple Account. Deleted photos wait in Recently Deleted for 30 days. Make your copy before you delete.
On the trip
The vault locks when the app goes to the background, after a time without a touch, and when you lock it. The app switcher shows a plain cover with the logo, not your files.
Face ID or Touch ID is off by default. Turn it on, and a face or finger opens the vault. Leave it off, and you need your pattern or passphrase. Your phone passcode never opens the vault either way.
A photo or video from the Vault9 camera goes only into the vault, holds no location and is not written to Photos. Files that you import from Photos or Files keep the metadata they had. The Vault9 camera has the details.
