End user licence agreement

Last updated: November 14, 2026

This end user licence agreement (“EULA”) is between you and Havelaar US, LLC, a Delaware limited liability company (“we”, “us”, “our”), for EchoOff for Batch & CMD (“the product”), including its updates. You accept it when you install the product, start a trial or buy a licence. If you accept it for an organisation, you confirm that you may bind that organisation, and “you” then means the organisation. If you do not accept it, do not install or use the product.

Who licenses the product

Havelaar US, LLC is the licensor of the product. JetBrains sells licences for it on JetBrains Marketplace, and you buy them from JetBrains under JetBrains’ own Purchase Terms. By “JetBrains” this EULA means the JetBrains company you buy from, which JetBrains’ checkout shows above the “Place Order” button, or its invoice shows: JetBrains Americas, Inc. for buyers in North and South America, JetBrains s.r.o. (Czech Republic) for most other buyers, and another JetBrains company in a few countries. If you buy through a JetBrains reseller, the reseller’s own terms apply to that purchase. JetBrains, its affiliates and its resellers are not parties to this EULA, and are not responsible for the product or liable to you in any way under this EULA.

Your licence

We grant you a limited, non-exclusive, non-transferable licence to install and use the product, worldwide, within the licence you bought:

• Personal licence: bought by an individual for themselves. Only that individual may use it, for any lawful purpose, on their own computers.
• Organisation licence: bought by a company or another organisation. It covers the number of users the organisation bought. Each user licence is used by one person at a time, whom the organisation chooses.

The licence lasts for as long as your subscription runs: to the end of each period you paid for, and on through each renewal. It does not continue after the subscription ends. During a free trial, you may use the product for the trial period to try it out.

What you may not do

Unless the law allows it despite this EULA, or we agree in writing, you may not:

• let more people use the product than your licence covers, or share, sell, rent, lend or sublicense it;
• copy it, except to install it within your licence and to keep a backup;
• modify, reverse-engineer, decompile or disassemble it, or make works derived from it;
• get around, disable or change its licence check;
• remove or change its copyright, licence or other notices;
• use it to break the law or anyone else’s rights.

Open-source components

The product includes these third-party open-source components. Each is licensed to you under its own licence, not under this EULA, and nothing in this EULA limits your rights under that licence.

• CheckLicense, from JetBrains' Marketplace sample plugin, under the Apache License 2.0: https://github.com/JetBrains/marketplace-makemecoffee-plugin

The programs the product runs, cmd.exe, which is part of Windows, are not part of it. They come with Windows, under the licence terms of your copy of Windows.

What is ours

The product, including its software, text, design and name, belongs to Havelaar US, LLC or its licensors, and is protected by copyright and other laws. You get a licence to use it, not ownership of it. What you work on with the product stays yours.

Your data

EchoOff for Batch & CMD collects no personal data and makes no network connections of its own: it sends nothing to us or to anyone else. It runs cmd.exe on your computer only when you start one of its run configurations. Our privacy policy says what personal data we receive when you buy, and what we do with it.

Updates and support

We may release updates, which your licence covers while it runs, and we may change the product as we improve it. Write to agent@osidius.com for help: we answer within 2 business days for an urgent problem, and within 5 business days otherwise. The product is written and maintained by AI agents of Havelaar US, LLC. Our replies are written by an AI agent of Havelaar US, LLC, and say so.

No warranties

The product is provided “as is” and “as available”, without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement. We do not promise that it will be uninterrupted or free of errors, that it meets your needs, or that every error will be corrected. You use it at your own risk.

Limitation of liability

To the fullest extent the law allows, Havelaar US, LLC is not liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits or data, arising from your use of the product, and our total liability for any claim is limited to the amount you paid for your licence of the product in the 12 months before the claim. Nothing in this EULA limits a right that the law where you live does not allow to be limited.

When the licence ends

Your licence ends:

• when your subscription ends without a renewal, at the end of the last period you paid for;
• when the payment for it is refunded, at the time of the refund;
• when a free trial ends, unless you buy a licence;
• if you break this EULA, when we tell you so, by email if we have your address.

When it ends, stop using the product and remove it. What this EULA says about what is ours, no warranties, the limitation of liability and the governing law still applies after it ends.

Governing law

This EULA is governed by the laws of the State of Delaware, without regard to its conflict of law rules. If you live outside the United States, for example in the European Union or the United Kingdom, you also keep the protection of the mandatory consumer law of the country where you live.

Changes to this EULA

We may change this EULA. We post the new version on this page and update the date above. A change applies to a licence from its next renewal, or from its purchase if it is bought after the change.

The rest

Our terms also apply to the product. Where they and this EULA differ about your licence, this EULA applies. If a part of this EULA cannot be enforced, the rest still applies.
