Android and browser app

Export and import a protected file

Share a study, Bible version, or commentary as an encrypted file or a readable JSON copy.

Before you start: Lamplighter 1.11.95 or later and an unlocked protected reader. These instructions describe the updated Android and browser apps; older desktop downloads may show different controls. The new export workflow passed software checks, but its complete file-picker and transfer journey on a physical Android phone has not yet been verified for this release.

Step by step

Choose one saved item.
For a study, open Studies and choose its Export action. For a Bible version, open its library entry and choose Export. For commentary, select it in the Commentary panel and choose Export commentary. The same File protection choices apply to all three.
Choose how the file is protected.
Encrypted file is selected initially. Choose Export encrypted file to save an .lpx file. Unencrypted file saves readable JSON outside protected storage, even while Lamplighter is hidden. Choose that only when you intend to keep or share a readable copy.
Save the file and keep its key available.
Approve the file destination. Android can show the game while its system picker is open; return and unlock again when prompted. The installation that created an encrypted export keeps its opening key inside protected storage. Clearing or reinstalling the app can lose that key.
Give another device access only when intended.
In the original item’s Export screen, choose Previous encrypted exports and Show decryption QR for that file. The matching QR opens only that export. Anyone who has both the file and QR can read it, so avoid public QR sharing, screenshots, or messages in places where discovery could put someone at risk.
Import and check the result.
Choose Import in Studies for a study, or Import version / Import commentary in the library for those resources. Select the file. The creating installation can open its own encrypted export; another installation asks you to scan or paste its matching decryption QR. Wait for verification and check the imported item before removing any source copy.

What to keep in mind

The browser app binds an export key to its saved browser installation. It does not provide hardware-backed proof that only one physical device can use that installation. Supported backups and transfers exclude these export keys.

An encrypted export stays readable to anyone already given its key; deleting the original or hiding its QR cannot recall copies. An unencrypted export has no protection outside the app. Encryption does not guarantee safety or privacy.

Native import attempts to remove the selected original only after checking its protected copy. Some file providers refuse removal, and browser apps cannot delete selected source files. Read the result and remove remaining copies yourself when appropriate. Deletion is not forensic erasure.

Full encrypted backups use a backup password and are a separate recovery tool. Legacy password-protected study files remain readable through compatibility import; they do not gain the new per-file QR protection.
