LanternDrop
Scan. Transfer. Done. Files and text between Windows and your phone, over your own network.
Releases and documentation only — source is not published.
01Overview
LanternDrop is a Windows 11 application for exchanging files and plain text with a phone on the same private local network. Scan one temporary QR code and transfer directly between the two devices — no phone application, browser extension, account, cloud storage or telemetry required.
Local transfers keep working without internet access. The only thing that ever leaves the network is an update check, and only when you ask for one or turn it on.
02Capabilities
Both directions
Send files and text from Windows to a phone, or receive them from the phone.
Temporary sessions
Expiring QR-code sessions with a random token, stopped manually or automatically.
Direct streaming
Transfers stream on the selected LAN, including HTTP Range downloads.
Careful with files
Collision-safe receives, upload cancellation and partial-file cleanup.
Honest progress
Per-transfer progress, bytes, speed and activity history.
Considerate UI
Dark and Light themes plus Reduce Motion.

06Safety, privacy & security
Caution
Use on a trusted network
- Transfer traffic uses local HTTP and is not encrypted. The temporary random token reduces casual unauthorized access, but it cannot protect traffic from a capable interceptor on the local network.
- Use LanternDrop only on a trusted private network or personal hotspot. Public or shared Wi-Fi is not recommended.
- LanternDrop has not received an external security audit.
Privacy
Privacy
- Files and text stay on the selected LAN and are never uploaded to a cloud service.
- No analytics or telemetry.
- Update checks happen only when requested or enabled, and never include transfer content, filenames, paths, clipboard text or session tokens.
07Known limitations
- Windows 11 x64 is the primary target.
- A trusted private LAN is required; IPv4 is used for sessions.
- Automatic download or installation of updates is not included.
