1. Acceptance
By downloading, installing, running, or using the Software, or by using the Site, you agree to these Terms, the Privacy Policy, and the Disclaimers. If you do not agree, do not download or use the Software and do not use the Site.
If you use the Software on behalf of a company, you represent that you have authority to bind that company, and “you” includes that company.
2. License grant
2.1 Free trial
We may provide a time-limited trial (currently up to 30 days, measured on your computer). The trial is licensed only for evaluation. Trial features, duration, and limits may change. The trial is personal and non-transferable.
2.2 Paid perpetual license
If you purchase a license, we grant you a personal, non-exclusive, non-transferable, perpetual license to install and use the Software on computers you own or control, for your internal business or personal use, subject to these Terms and any license key or activation instructions we provide. “Perpetual” means the license does not expire by calendar date; it does not guarantee free updates forever or unbroken compatibility with future Windows versions.
2.3 What you may not do
- Sell, rent, lease, sublicense, or publicly redistribute the Software or license keys, except as we expressly allow in writing.
- Circumvent, disable, or interfere with trial limits, license checks, or other technical protections.
- Remove or alter copyright, trademark, or attribution notices.
- Use the Software to violate applicable law, or to attack, disrupt, or gain unauthorized access to systems you do not own or control.
- Misrepresent the Software as safety-certified, SIL-rated, or approved for life-critical or regulatory safety functions.
3. Industrial and network use
The Software is a general-purpose Modbus TCP/RTU test, simulation, and automation tool. It is not a certified safety instrumented system, PLC, protective relay, or medical device.
You alone are responsible for: (a) obtaining permission to access any device or network; (b) isolating test equipment from production where appropriate; (c) validating every write, script, and simulated slave before use on live plant; and (d) complying with workplace, electrical, and cybersecurity rules that apply to you.
See also the Disclaimers.
4. Purchases and refunds
List price and offer details on the Site are informational. A purchase is complete only when we confirm payment and issue license credentials by email or other written channel we designate.
Unless required by mandatory consumer law in your place of residence, or we agree otherwise in writing: (a) license fees are non-refundable after credentials are delivered; (b) chargebacks after delivery may result in license revocation. If the Software is materially defective and we cannot provide a reasonable fix or workaround within a commercially reasonable time after you report it with enough detail to reproduce, contact us to discuss a remedy.
5. Updates and changes
We may release updates, change features, or discontinue the Software or Site. We may change these Terms by posting an updated version with a new “Last updated” date. Continued use after the update means you accept the revised Terms. Material license price changes do not retroactively alter a license you already paid for, except as required by law.
6. Intellectual property
We and our licensors retain all rights, title, and interest in the Software, Site, branding, documentation, and example projects, except for the limited license granted to you. Feedback you send may be used by us to improve the product without obligation to you.
7. Third-party components and links
The Software and Site may include or link to third-party libraries, tools, or websites. Those are governed by their own terms. We are not responsible for third-party content or services.
8. No warranty
To the maximum extent permitted by law, the Software and Site are provided “AS IS” and “AS AVAILABLE”, without warranties of any kind, whether express, implied, or statutory, including merchantability, fitness for a particular purpose, title, non-infringement, accuracy, or uninterrupted availability.
Builds may be unsigned. Operating systems may show security warnings (for example Windows SmartScreen). You decide whether to run the Software.
9. Limitation of liability
To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, consequential, exemplary, or punitive damages; lost profits, revenue, data, or goodwill; business interruption; or cost of substitute tools — arising from the Software, Site, trial, license, or these Terms — whether in contract, tort (including negligence), or otherwise, even if advised of the possibility.
To the maximum extent permitted by law, our total liability for all claims relating to the Software, Site, or these Terms is limited to the greater of: (a) the amount you paid us for the license giving rise to the claim in the 12 months before the claim, or (b) USD $79 if you paid nothing.
Some jurisdictions do not allow certain limitations. In those cases, our liability is limited to the minimum permitted by law.
10. Indemnity
You will defend and indemnify us against claims, damages, losses, and reasonable legal fees arising from: your use of the Software or Site; your Modbus writes, scripts, or simulated slaves; your violation of these Terms or law; or your infringement of another’s rights — except to the extent caused by our willful misconduct.
11. Termination
Your license ends automatically if you materially breach these Terms. We may revoke a license obtained by fraud or payment reversal. On termination you must stop using the Software and destroy copies in your possession, except copies you must keep under law. Sections that by nature should survive (including 6–10, 12–14) survive termination.
12. Export and sanctions
You must not use or export the Software in violation of applicable export-control or sanctions laws.
13. Governing law and disputes
These Terms are governed by the laws of Taiwan (Republic of China), without regard to conflict-of-law rules. Courts located in Taiwan have exclusive jurisdiction, except that we may seek injunctive relief in any court for IP or license abuse. Mandatory consumer protections in your country of residence still apply if they cannot be waived.
14. Miscellaneous
These Terms, with the Privacy Policy and Disclaimers, are the entire agreement for the Software and Site. If a clause is unenforceable, the rest remains in effect. Failure to enforce a right is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a transfer of the product. Notices to us must be sent to mr.roach.company@gmail.com.
