TROMINIT & Data Security
Your data stays on your laptop.
Track2go is a Windows app that runs without the internet. No cloud, no accounts, and no athlete data sent anywhere. This page is written for your IT team — forward it as is.
No athlete data leaves
No cloud, telemetry or license server. The only outbound request is an update check.
Localhost-only UI
The app’s interface and API listen on 127.0.0.1 only.
Local SQLite
One database file on the laptop’s own disk.
Isolated field network
Receivers sit on their own Wi-Fi, separate from campus networks.
Data
What is stored, and where
| Location | C:\TrominTrack2go (configurable) |
|---|---|
| Database | SQLite, single file |
| Athlete data | Name, jersey number, position, height, weight, jump height, tag assignment history |
| Not collected | Birthdate, gender, email, phone, health records |
| Raw sensor logs | 50 Hz motion data, gzip-compressed after each session; oldest removed past a 50 GB cap |
| Backups | Daily database copy, last 14 kept |
| App logs | Kept 14 days |
| Exports | CSV and PDF, saved locally by the user |
| Uninstall | Removes the app; data folder is kept until deleted manually |
Installation
Install and system requirements
| OS | Windows 10 or 11, 64-bit |
|---|---|
| Runtime | .NET is bundled. Windows 10 needs the Microsoft WebView2 Runtime (preinstalled on Windows 11) |
| Install | Per-machine, to Program Files. Administrator rights required |
| Field network switch | Changing the Wi-Fi adapter address shows a Windows admin (UAC) prompt |
| Disk | Warns below 10 GB free; a live session saves and stops automatically below 1 GB |
| Update check | Every 6 hours (never during a live session) the app reads a version file from track2go-updates.pages.dev over HTTPS. No athlete data is sent. Updates install only when the coach confirms. Blocking this domain does not affect any other function |
