What DNP3 Explorer Does

DNP3 Explorer is a native macOS application for DNP3 (IEEE 1815) communication. It operates as a DNP3 master to poll outstations, or as a DNP3 outstation to simulate devices. It runs entirely on your Mac.

Data Collection

DNP3 Explorer does not collect, transmit, or store any personal data. Specifically:

• No DNP3 data leaves your Mac. All point values, event records, and communication logs exist only in the app's memory and your local storage.
• No device information is collected. IP addresses, master/outstation addresses, and point configurations entered in the app are stored locally for your convenience and never sent anywhere.
• 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 makes network connections only to the DNP3 devices you explicitly configure:

• DNP3 TCP: Connects to the IP address and port you specify to poll or simulate outstations
• DNP3 Serial: Communicates via USB-to-serial adapters, no network involved
• License activation (DMG version only): If you purchased via Polar.sh, the app contacts dl-dnp3-explorer.voltrus.id to validate your license key. This sends only your license key and a device identifier — no other data.

The Mac App Store version does not include license activation — Apple handles everything.

Local Storage

The app stores the following data locally on your Mac:

• Connection profiles (IP, port, master/outstation addresses) — stored in app preferences
• Point configurations — stored in app preferences
• License activation data (DMG version only) — stored in macOS Keychain
• Communication logs — stored in memory only, cleared when the app closes

All local data can be deleted by removing the app. No residual data is left on your Mac after deletion.

License Purchase

Licenses for the DMG version are processed through Polar.sh. We receive only your email address and purchase details. We do not receive or store payment card information. License keys are managed by Polar.sh.

The Mac App Store version is processed by Apple. We receive only the information Apple provides through App Store Connect (sale reports with anonymized data).

Children's Privacy

DNP3 Explorer is an industrial automation 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/dnp3-explorer/) uses privacy-focused analytics (One Dollar Stats) that does not use cookies or track individual users. The app itself contains zero analytics.

Third-Party Services

• Polar.sh — Payment processing and license key management (DMG version only). Their privacy policy applies to purchase data.
• Apple App Store — Payment processing and distribution (App Store version). Apple's privacy policy applies.
• Cloudflare — Hosts the license validation and update server. No personal data is stored on Cloudflare beyond temporary request logs.

Data Retention

We retain your email address (from Polar.sh purchases) for as long as necessary to provide license support. We do not maintain any database of users, devices, or usage patterns. 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.
