Windows 10/11 (x64) · Free · No account needed
System requirements
DataTray runs on any Windows 10 or 11 machine. It reads files off your disk rather than loading them into memory, so it does not need a workstation to open a big one.
Operating system
Windows 10/11 (x64)
Architecture
64-bit (x64) processor
Installer size
One installer and nothing after it — no AI models, no database engine to install, no extensions fetched on first use, no account
AI models
None — DataTray ships no models and asks for no API keys
What's in the download
There is no second step. Everything DataTray needs is in the installer, so the first time you open a spreadsheet it does not go and fetch anything.
In the installer
- All five tools — Explorer, Converter, Dedupe & Merge, Clean & Anonymize and Compare
- The query engine that reads CSV, Excel, Parquet and JSON off your disk
- The offline lookup tables behind personal-data detection — no model, no API key
What downloads later
Nothing. No AI models, no database engine, no extensions fetched on first use — which is also why DataTray works on a machine with no internet connection at all.
Signed & verifiable
EV Authenticode code-signed
Every DataTray installer is signed with an Extended Validation Authenticode certificate. Windows SmartScreen and the User Account Control prompt will show DataTray as the verified publisher, so you can be sure the file came from us and hasn’t been tampered with in transit.
A published SHA-256 checksum will appear here alongside the first public release, so you can verify your download independently of the signature.
If Windows shows a SmartScreen warning
Our installer is signed with a brand-new certificate that hasn’t built up reputation yet, so the first people to download may see a blue “Windows protected your PC” screen. It’s expected and harmless. Click More info → Run anyway to continue. The warning clears itself as more people install safely.
How it stays free
DataTray is funded by sharing a slice of your PC’s idle, unused internet bandwidth through Massive, our vetted partner. It relays other people’s web traffic — it never reads or sends your files. You are told at install, before anything runs, and the toggle is one click from the tray menu.
