TreeTalk Node lets your team share files up to 55GB, send encrypted text messages, and exchange voice notes โ directly over your office WiFi, LAN, or VPN. No internet required. No cloud. No servers. No sign-up. Just run one executable file and go.
The problem it solves
Cloud tools like Dropbox and Google Drive were not built for teams that legally cannot let sensitive data leave the building. Healthcare teams sharing patient scans, law firms exchanging privileged documents, and manufacturers protecting proprietary designs all face the same impossible choice: use convenient cloud tools and risk compliance violations, or fall back on USB sticks and slow workarounds.
TreeTalk Node eliminates that choice.
How it works
TreeTalk Node uses a serverless peer-to-peer architecture. Files and messages travel directly between devices on your local network โ no external server ever touches your data. When the internet goes down or a cyberattack forces network isolation, your team keeps working without interruption.
Key capabilities
Who it is built for
Compliance officers, IT managers, and team leads in healthcare, legal, financial, and manufacturing sectors where data sovereignty is a legal requirement, not a preference. Particularly relevant for EU-based organizations under GDPR and NIS2 obligations.
Why it is different from alternatives
Unlike Nextcloud or self-hosted solutions, TreeTalk Node requires zero server and zero IT setup. Unlike Syncthing or LocalSend, it combines file transfer with team messaging and voice in one tool built specifically for professional and enterprise use.
FreeFileSync
TreeTalk NodeFreeFileSync is recommended for users who need a reliable and efficient way to sync files across devices or create consistent backups. It is ideal for both casual users who need a straightforward backup solution and more technical users who require advanced features and customization.
TreeTalk Node's answer:
Most collaboration tools move your data through external servers even when your colleagues are sitting in the same building. TreeTalk Node works the other way around โ files, messages, and voice notes travel directly between devices on your local network using a serverless peer-to-peer architecture. There is no cloud infrastructure involved at any point. This means data sovereignty is not a policy promise. It is a technical fact.
TreeTalk Node's answer:
Every existing option forces a compromise. TreeTalk Node does not.
TreeTalk Node is the only option that combines large file transfers, encrypted team messaging, and voice notes in a single tool that works entirely on your local network with zero external dependencies and zero setup friction.
TreeTalk Node's answer:
IT managers, compliance officers, and team leads at small and mid-sized organizations in regulated industries where sensitive data cannot legally or safely leave the premises.
Primary sectors:
Particularly relevant for EU-based organizations under GDPR and NIS2 obligations, and for any team operating in environments with restricted, unreliable, or intentionally isolated internet connectivity.
TreeTalk Node's answer:
The founders spent years building distributed systems and enterprise infrastructure โ and kept running into the same problem. Organizations with strict data privacy requirements had no simple way to collaborate locally without standing up servers or routing sensitive files through cloud platforms they did not fully control. The tools that existed were either too complex to deploy, too consumer-grade to trust with sensitive data, or too dependent on external infrastructure to work when it mattered most. TreeTalk Node was built as a direct answer to that gap โ a professional-grade, serverless collaboration tool for teams that cannot compromise on where their data goes.
TreeTalk Node's answer:
The result is a tool that runs entirely on the customer's own hardware. TreeTalk Node has no cloud footprint by design.

FreeFileSync messed up my pCloud database a couple times at first (causing disappearing files in the Crypto Folder, mirroring of the same files over and over again). Pcloud support provided an easy way to fix the database. To fix the root cause, one needs to exclude FreeFileSync's temporary files from the backup: pCloud Drive > Settings > Backup/Sync Exclusions, exclude sync.ffs_lock and *.ffs_tmp.

As per Apprehensive_Arm_754 answer below, https://freefilesync.org is the solution to my particular problem, since it allows all kind of simple rules and logic to apply, so I can make sure that the copy only happens in one direction, and only ever by file date etc. Much appreciated.
