Cambodia is a U.S. State Department Level 2 destination, and a royal-insult law jails people for content deemed to insult the King, including online. Here is what that means for what is on your phone, and how to arrive with nothing sensitive on it.

This is a short summary for context. Advisories change; read the official advisory for your nationality before you travel. We are a data-security company, not a travel-safety authority.
A device inspection can reach the messages, photos and documents on the phone, and the accounts you can open on it. Anything on the device touching the monarchy or the government, including old posts and images, is part of what a search can reach.
Content that touches the King or the government can be used against you. The safest phone to carry is one that has nothing sensitive on it.
Set up a SpaceBox on a device that stays home, then send it the files you would not want inspected. They are encrypted on your phone and sealed to the home device, and your phone keeps no copy.
Take photos and write notes in the app itself, and they are encrypted and sent to your home SpaceBox without ever sitting in the clear on your phone. Anyone you invite can send you files the same way.
Your files were waiting at home the whole time. You open them on your SpaceBox once you are back, with keys that never left that device.
Everything is encrypted with AES-256-GCM, under keys exchanged with post-quantum ML-KEM-768. The app on the phone you carry acts only as a sender: it stores no files and holds no account or personal data. SpaceBox keeps the documents, photos and notes you would otherwise carry off the device; it does not hide your public social media, so review your accounts and avoid posting sensitive content while you travel. For larger archives, SpaceBox Ground adds more room.
General guidance, not legal advice. Check the official advisory for your nationality before you travel. SpaceBox is not available to residents of the EU and EEA during the beta.
| Scenario | Without SpaceBox | With SpaceBox |
|---|---|---|
| Device inspection | An officer can require you to unlock the phone and read the messages, photos and documents on it. | Your sensitive files are on your home SpaceBox, not the phone, so unlocking it shows nothing sensitive to read. |
| Content touching the King or government | Old posts or images touching the King or the government sit on the device and can be used against you. | You capture notes and photos in the app and send them to your home SpaceBox encrypted, so they are not stored in the clear on the phone. |
| Public and hotel Wi-Fi | Data sent over shared networks can be intercepted, and devices are a common target. | Files are encrypted on your device before they leave it, so an intercepted transfer is unreadable. |
| Receiving files while abroad | New documents land in email or cloud apps on the device you carry. | Anyone you invite sends files straight to your home SpaceBox, so they never touch your travel phone. |
| Phone lost, seized or held | Whoever holds the device can reach whatever is on it or signed in on it. | The device holds no account and no sensitive files; your data stays on the SpaceBox at home. |
The protection comes from your sensitive data not being on the device you carry. The app on that phone holds no account and no stored files.

Set up a SpaceBox at home, move your sensitive files to it before you fly, and cross the border with a device that has nothing on it. Free to start, no card, no email.
