TreeTalk Node: File Transfer

TreeTalk Node lets nearby phones, tablets and computers share files, photos, videos, text and voice messages directly, without a router, an account, or an internet connection.

No WiFi around? Turn on your phone's hotspot. TreeTalk Node finds every nearby device in seconds. No internet, no router required.

CORE BENEFITS
• Direct device-to-device sharing, no cloud upload and download
• Works over any shared WiFi, hotspot, LAN, or user-configured VPN without isolation
• No advertising, analytics, tracking, or social login
• Automatic discovery of nearby devices with TreeTalk Node instance started
• Send multiple files straight from your Gallery or File manager, not one at a time
• Optional strong encryption for files and messages
• User-selected receiving folders

MORE THAN FILE TRANSFER
Most local sharing apps stop at one device sending to another. TreeTalk Node also gives your whole group one shared space:
• Group text chat and group voice, encrypted, not just device-to-device
• Push-to-talk style voice messages with autoplay, for fast back-and-forth without pressing Download/Play each time
• Deep Work mode, when you'd rather messages wait than interrupt you
• Send a file to everyone in the group at once

PRIVATE BY DESIGN
Encryption keys stay on your device and are never broadcast, unlike apps that exchange keys over the network. Files, messages, and voice recordings go directly to the peer or group you choose. Nothing is uploaded to TreeTalk. The Android app includes no advertising, analytics, attribution, tracking, crash-reporting, Firebase, or social-login SDKs.

FOR FAMILIES AND FRIENDS
Send vacation photos and videos to a family member's phone or laptop without the Bluetooth pairing wait, without a hard size limit, and without uploading anything to a third-party cloud first.

FOR TEAMS
Hospitals, law firms, hotels, and warehouses use TreeTalk Node to coordinate and move files on their own network, keeping data on the premises, and staying operational even when the internet goes down.

PRO FEATURE EVALUATION
The Free app includes an evaluation of selected Pro functions. During the evaluation you can send up to 30 voice messages and up to 30 individual files through the multi-file sending feature. Each allowance ends when it is used or when the 7-day period ends, whichever occurs first.

AFTER THE EVALUATION
TreeTalk Node continues to work under the permanent Free limits:
• Unlimited Files up to 100 MB each
• Unlimited text messages
• Single-file sending remains available
• Previously received files and messages remain on your device

SECURITY NOTICE
Encryption is a tool, not a substitute for correct configuration. Replace any default passphrase with a strong unique passphrase before sending sensitive information, verify recipients, and protect receiving folders.

Network performance and maximum practical transfer size depend on the participating devices, storage, and network conditions.
