Privacy Policy

Last updated: November 10, 2026

        TL;DR: CAN Explorer is a native macOS app. It does not collect, transmit, or store any personal data. Bus data flows only between your Mac and the CAN adapter you connect. No analytics, no tracking, no phone-home beyond licence activation.
      

What CAN Explorer Does

CAN Explorer is a native macOS application that reads and sends CAN and CAN FD frames through a USB CAN adapter (or a SocketCAN interface on Linux), decodes them, and can run a bus simulator on a virtual bus inside the app. It runs entirely on your computer.

Data Collection

CAN Explorer does not collect, transmit, or store any personal data. Specifically:

No bus data leaves your Mac. Frames, decoded signals and traces exist only in the app's memory and in files you record or export yourself.
No usage analytics. The app does not include any analytics SDK, tracking pixels, or telemetry. We do not know how you use the app.
No crash reporting. The app does not send crash reports automatically. If you report a bug, you choose what information to share.

Network Communication

The app talks to CAN adapters over USB and opens no network connection to read a bus. The bus simulator runs on a virtual bus inside the app and does not listen on the network. The only communication with Voltrus is:

Licence activation: If you enter a Pro licence key, the app contacts dl-can-explorer.voltrus.id. The request contains your licence key, a device identifier, the app version and the platform (for example macos-aarch64). While a key is saved, the app re-checks it with the same server about once per launch and sends the same fields plus the activation ID. Removing the key tells the server to release the activation. No other data is sent.

Local Storage

The app stores the following data locally on your Mac:

Saved interface profiles (adapter port, bit rates and options you choose to save): stored in app preferences
Licence key, activation ID and the device identifier: stored in the macOS Keychain
Files you record or export, such as candump logs and CSV traces: written to a place you choose

All local data can be deleted by removing the app and its Keychain entry.

Licence Purchase

Licences are processed through Polar.sh. We receive only your email address and purchase details. We do not receive or store payment card information.

Children's Privacy

CAN Explorer is an engineering tool. It is not directed at children under 13. We do not knowingly collect information from children.

Cookies and Analytics

This product page (voltrus.id/can-explorer/) 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

Polar.sh: Payment processing and licence key management. Their privacy policy applies to purchase data.
Cloudflare: Hosts the licence validation and download server. No personal data is stored on Cloudflare beyond temporary request logs.

Trademarks

CANopen is a registered trademark of CAN in Automation e.V. CAN Explorer is not affiliated with or endorsed by CiA, SAE or the makers of the adapters it supports.

Data Retention

We retain your email address (from Polar.sh purchases) for as long as necessary to provide licence support, and the activation record (key, device identifier, app version, platform) for as long as the licence is active. You can request deletion of your purchase data by emailing us.

Your Rights

Depending on your jurisdiction, you may have the right to:

Request access to the personal data we hold about you
Request deletion of your personal data
Object to processing of your personal data
Request a copy of your data in a portable format

Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of the app after changes constitutes acceptance.
