        TL;DR: Voltrus Tools is a native macOS app. It collects no data. Everything you configure and record stays on your Mac. There is no account, no analytics, no tracking and no crash reporting. The only thing the app sends to us is your licence key when it activates or checks it.
      

What Voltrus Tools Does

Voltrus Tools is a Mac app for industrial protocols: Modbus, MQTT, BACnet, OPC UA, Siemens S7, EtherNet/IP, DNP3, NATS, serial ports, Bluetooth LE, MTConnect, FANUC (FOCAS/Ethernet) and SECS/GEM. It connects to devices you choose, reads and writes their values, trends them, and runs simulators of those devices on your Mac. It runs entirely on your Mac.

Data Collection

Voltrus Tools does not collect, transmit or store any personal data on our servers. The one exception is the licence check, described under Licence key below.

No device data leaves your Mac. Points, values, trends, traffic and logs exist only in the app and in its local storage.
No connection details are collected. Addresses, ports, user names, passwords, certificates and credential files you enter stay on your Mac.
No usage analytics. The app has no analytics SDK and no telemetry. We do not know how you use it.
No crash reporting. The app sends no crash reports. If you report a bug, you choose what to share.

Network Communication

Apart from the licence check, the app connects only to the devices, servers and brokers you configure, and listens on the network only while you run one of its simulators (by default on 127.0.0.1, this Mac only). BACnet and EtherNet/IP discovery send broadcasts on your local network when you ask for them. Serial ports and Bluetooth LE devices are used only when you open them.

Local Storage

The app keeps these on your Mac, in its own application data folder and the macOS Keychain:

Your connections, simulators, layouts and settings
Certificates the OPC UA client and server use, and files you pick in an open panel
The licence state (trial start, licence key, its activation id and a random device id), with Keychain entries that keep the trial from being reset
Log files, only when you choose Log to file… and pick where they go

Removing the app does not remove the Keychain entries; you can delete them in Keychain Access.

Trial and licence key

The 14-day trial runs on your Mac and sends nothing. A licence key is bought through the Voltrus Console, where the payment is processed by Polar; we never see your card details. When you activate the key, and once per launch afterwards, the app sends the key, its activation id, a random device id, the app version and the platform to our licence server (dl-voltrus-tools.voltrus.id) to check that the key is valid for this Mac. Removing the key releases this Mac's seat. Nothing else is sent.

Children's Privacy

Voltrus Tools is an industrial engineering tool. It is not directed at children under 13, and it collects no information from anyone.

Cookies and Analytics

This product page (voltrus.id/voltrus-tools/) counts page views and clicks with One Dollar Stats and RevKlik. Neither sets cookies. RevKlik stores a random visitor ID in your browser; the Voltrus privacy page lists what it records. The app itself contains zero analytics.

Third-Party Services

Voltrus Console and Polar: buying the licence key. The Voltrus privacy page and Polar's privacy policy apply.
Cloudflare: hosts the download and the licence server.

Your Rights

We hold no personal data from the app beyond the licence key and its activations. If you email us, we keep the email only as long as we need it to help you, and delete it on request.

Changes to This Policy

We may update this policy. Changes will be posted on this page with a new date.
