Terms of Service

Last updated: November 9, 2026

1. Who you are dealing with

TryPLC is operated by the TryPLC Team, trading as TryPLC ("TryPLC", "we", "us"). When you use tryplc.com or buy a Pro plan, your agreement is with the TryPLC Team.

2. Acceptance

By using TryPLC, and by continuing to use it after these terms change, you agree to these terms. If you do not agree, do not use the service. If you use TryPLC on behalf of a company or school, you confirm you are allowed to accept these terms for it. If you buy a Pro plan, you confirm you are old enough to enter a contract where you live, or that a parent or guardian has agreed to these terms for you.

3. The service

TryPLC is an educational platform: lessons, a browser-based Structured Text, ladder and SFC simulator, a book, articles, reference pages and calculators. Most of it is free. An optional paid Pro plan opens additional chapters and practice, as described on the pricing page.

The simulator and lessons are for learning purposes only and must not be used as a substitute for production-grade PLC engineering tools or for safety-critical decisions. Real controllers differ from the simulator in timing, memory handling and vendor extensions. Always commission and validate a real machine with the manufacturer's own software and procedures, and follow the safety standards that apply to it.

4. Your account

You can use most of TryPLC without an account. If you create one, you are responsible for any activity under it. Keep your credentials private and give us accurate information when you sign up, and keep it up to date. You can ask us to close your account at any time; see the privacy policy for what happens to your data.

5. Acceptable use

You agree not to:

• use the service for anything unlawful, or to harm other people;
• use it for fraud, spam, or to send unsolicited messages;
• infringe anyone's intellectual property, including by copying in bulk or republishing the lessons, book, articles or Pro chapters;
• interfere with the security of the service: uploading malware, probing it for weaknesses, scraping it, or overloading it with automated requests;
• get around access limits, share a Pro account so that others avoid paying, or reverse engineer the platform;
• click or generate traffic on advertisements artificially, or ask others to.

6. Intellectual property

The TryPLC Team owns the service and everything in it: the software and simulator engine, lessons, exercises, the book, articles, documentation and the TryPLC name and branding, unless stated otherwise. Using TryPLC, free or Pro, gives you a personal, non-exclusive, non-transferable right to use it for learning. You may quote short extracts with a link back to the source. You may not redistribute, resell or sublicense any of it.

Product and company names such as ABB, KUKA, FANUC, Siemens and Rockwell Automation belong to their owners. They appear here only to describe the equipment our material is about. TryPLC is independent and is not affiliated with, sponsored or endorsed by any of them.

7. Your code and messages

Code you write in the editor and progress you save stay yours. You allow us to store and process them only so we can run the service for you. If you send us a message, a correction or a suggestion, you allow us to use it to improve TryPLC without owing you anything for it. We will not publish your name or email address without asking you first.

8. Pro plan, payments and refunds

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

Payment, billing, renewal, taxes and cancellation for Pro plans are governed by Paddle's Buyer Terms. In short: Pro Monthly renews every month and Pro Yearly every year until you cancel; prices are shown on the pricing page and taxes are added where they apply; you can cancel at any time from "Manage subscription", and Pro then stays active until the end of the period you paid for. Refunds are described in our refund policy.

9. Advertising and third-party services

Free parts of TryPLC show advertising served by Google on article and reference pages. Advertisers and their content are selected by Google and are not endorsed by us. We also rely on third-party services for hosting, sign-in, payments and analytics. Your use of those services is also subject to their own terms; how they handle your data is described in our privacy policy.

10. Availability

We work to keep TryPLC available but do not promise it will be uninterrupted or error-free. We may change, suspend or withdraw any part of it, including features and content, at any time. If we withdraw a paid feature you have already paid for, we will offer a fair solution, such as a partial refund.

11. Suspension and termination

We may suspend or close an account, or end Pro access, if there is a material breach of these terms, a payment is not made or is reversed, the account creates a security or fraud risk, or the account repeatedly or seriously breaks these rules. Where we reasonably can, we will tell you why. When an account is closed, its data is deleted as described in the privacy policy.

12. Disclaimer and liability

The service is provided "as is" without warranty of any kind, including implied warranties of merchantability or fitness for a particular purpose, to the fullest extent the law allows. We are not liable for indirect or consequential losses arising from your use of the platform, such as lost profits, lost data or reliance on simulator output or lesson content for real-world automation work. Our total liability to you is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability for fraud, death or personal injury, or any right you have by law that cannot be limited.

13. Changes

We may update these terms and will change the date at the top when we do. Continued use after changes constitutes acceptance.
