Terms of Service & License Agreement

Last updated: October 10, 2026

1. Who we are

Voltrus is a product brand of PT Joyo Digitama Solusi, a limited liability company registered in East Java, Indonesia and a VAT-registered business (Pengusaha Kena Pajak). "We", "us" and "Voltrus" mean PT Joyo Digitama Solusi. "You" means the person or organisation that buys, installs, or uses our software or services.

By buying, downloading, installing, or using any Voltrus product, or by creating an account on console.voltrus.id, you agree to these terms. If you accept them for an organisation, you confirm you are authorised to bind it.

2. What these terms cover

• One-time software licenses: the MacTools apps (Modbus Poll, BACnet Explorer, OPC-UA Explorer, MQTT Explorer, NATS Explorer, S7 Explorer, DNP3 Explorer, EtherNet/IP Explorer, PasteHere; BLE Inspector and Serial Monitor are free downloads), the MacTools Any 2 and MacTools Everything bundles, and other Voltrus software sold as a perpetual license (for example Voltrus SCADA, Voltrus Gateway and the terminal database tools).
• MacTools Pro: a yearly subscription to every MacTools app.
• Hosted subscriptions (SaaS): Voltrus MES, Voltrus OEE, Voltrus Broker, Voltrus Remote and Voltrus Factory.

A signed order form, quote, or partner agreement takes precedence over these terms where the two conflict. Apps bought through the Mac App Store are also subject to Apple's Licensed Application End User License Agreement.

3. Your account

Licenses and subscriptions are tied to the email address used at purchase and managed in the Voltrus Console. Keep your sign-in email secure; you are responsible for activity under your account and for the people you invite to it. Tell us at [email protected] if you suspect unauthorised use.

4. Software license (EULA)

The software is licensed, not sold. Subject to these terms and to paying the applicable fee, we grant you a non-exclusive, non-transferable license to install and use the software for your own business or personal purposes, on the number of machines (activations) stated at purchase. MacTools Everything includes three machine activations on one license key.

One-time (perpetual) licenses do not expire. They keep working for the version you bought even if we later stop releasing updates for that product. Updates are provided as described on each product page.

You may not:

• resell, rent, sublicense, or share license keys outside the activations you bought;
• bypass, disable, or tamper with license activation;
• decompile or reverse engineer the software, except to the extent the law allows despite this restriction;
• use the software or services to break the law or to attack systems you are not authorised to access.

We (and our licensors) keep all intellectual property rights in the software, documentation, and services. Third-party open-source components are licensed under their own terms, which take precedence for those components.

5. MacTools Pro subscription

MacTools Pro is billed yearly in USD. While your subscription is active it gives you a license for every MacTools app, current and future, all updates, and priority email support. It renews automatically each year until you cancel. You can cancel at any time in the Voltrus Console; the subscription then stays active until the end of the paid year and is not renewed.

When a MacTools Pro subscription ends, the license it granted ends too. Per-app or bundle licenses you bought separately are perpetual and are never affected by starting or cancelling MacTools Pro. If a renewal payment fails, we may keep access open for a short grace period while the payment is retried.

6. Hosted subscriptions (SaaS)

Voltrus MES, OEE, Broker, Remote and Voltrus Factory are provided as hosted services on a monthly or yearly subscription (or, where offered, a prepaid balance such as a Broker QRIS top-up). Plans, limits (for example machines, users, device connections, or traffic) and prices are shown on each product page or in your order form.

• Renewal and cancellation. Subscriptions renew automatically for the same period until cancelled. You can cancel at any time; service continues until the end of the current paid period.
• Non-payment. If a payment fails or a prepaid balance runs out, we may suspend the service after any stated grace period. Data is kept for at least 30 days after suspension so you can pay or export it.
• Your data. You own the data you put into the services. We process it only to provide, secure, and support the service, as described in our privacy policy. After cancellation you can request an export within 30 days; after that we may delete it.
• Availability. We work to keep the services available, but unless a signed order form states a service level, we do not guarantee uninterrupted service. Planned maintenance is announced in advance where practical.
• Fair use. Stay within your plan's limits. If you consistently exceed them, we will contact you to move to a suitable plan before taking any other action.
• Changes. We may improve or change features. We will not materially reduce a paid feature during a term you have already paid for.

7. Prices, payment and tax

• Card payments are processed by Polar, which acts as the merchant of record for those orders and charges any sales tax or VAT that applies in your country.
• Bank transfer and QRIS payments are invoiced by PT Joyo Digitama Solusi in Indonesian Rupiah. Rupiah prices exclude PPN (Indonesian VAT), which is added at the prevailing rate. As a PKP we issue a faktur pajak for these payments on request.
• We may change prices for future purchases and renewals. For subscriptions we give at least 30 days' notice before a price change applies to your next renewal.

8. Refunds

Refunds are covered by our Refund Policy, which forms part of these terms.

9. Industrial use and safety

Our software reads, writes, and monitors industrial equipment. You are responsible for how it is configured and used on your systems. Do not rely on it as a safety function or a safety-instrumented system, and test write operations before using them on live equipment. Voltrus software is not designed for use where its failure could lead directly to death, personal injury, or severe environmental damage.

10. Warranty

We will fix reproducible defects that we confirm, or refund you under the Refund Policy. Beyond that, and to the extent the law allows, the software and services are provided "as is", without other warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement.

11. Limitation of liability

To the extent the law allows, we are not liable for indirect or consequential losses (including lost profits, lost production, or lost data), and our total liability for any claim is limited to the amount you paid us for the product or service concerned in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited under Indonesian law.

12. Suspension and termination

We may suspend or end a license or service if you materially breach these terms and do not fix the breach within 14 days of our notice, or immediately where needed to stop abuse or a security threat. You may stop using our products at any time.

13. Changes to these terms

We may update these terms. The "last updated" date above shows the current version. Material changes that affect paid subscriptions are announced by email at least 30 days before they take effect; they apply from your next renewal.

14. Governing law and disputes

These terms are governed by the laws of the Republic of Indonesia. We will first try to resolve any dispute by good-faith discussion for 30 days. If that fails, the dispute will be settled by the competent district court (Pengadilan Negeri) for our registered office, unless mandatory consumer law gives you the right to another forum.
