Terms of Service & License Agreement

Last updated: 21 September 2026

Who You Are Buying From

ArchPlug is operated by ArchPlug DOO Beograd-Zvezdara, a limited liability company registered in the Republic of Serbia (company reg. no. / MB 22315285, tax ID / PIB 115780969), Jovanke Radaković 118, 11160 Belgrade, Serbia · support@archplug.com · +381 61 425 0707 ("ArchPlug", "we", "us", "our").

Payments are processed by Paddle.com, which acts as our merchant of record: Paddle is the seller of record for the transaction, issues your invoice and handles sales tax/VAT, and Paddle’s Buyer Terms apply to the payment itself. These terms govern the software licence, which is granted by ArchPlug DOO. (Purchases made before Paddle was introduced were processed by PayPal and remain valid under these terms.)

Acceptance of Terms

By downloading, installing, or using any ArchPlug plugin you agree to these Terms of Service and License Agreement. If you do not agree, do not install or use the software. If you use the software on behalf of a company, you confirm that you may accept these terms for it.

License Grant

ArchPlug grants you a non-exclusive, non-transferable, limited licence to install and use the software for your personal or professional work. The software is licensed, not sold.

• Per person, tied to your account. A paid licence belongs to one person and is tied to that person’s ArchPlug account (email address). You may install the software on any number of your own machines, but it may only be in active use on one machine at a time per account. Each additional person in an office needs their own licence.
• Perpetual licences (single plugin or Lifetime Bundle) let you use the purchased major version without time limit, subject to these terms.
• Subscriptions (where offered) let you use the covered plugins only while the subscription is active and paid.
• Purchases are made through your ArchPlug account; installers for your licensed plugins are available after logging in at archplug.com/account.

Free Trial

Each paid plugin can be tried free of charge for 14 days, fully functional, with no payment details. To start a trial you enter your email address in ArchPlug Settings; no password account is needed. The trial period starts when the plugin is first activated on your computer, and one trial is available per person and per computer — using new email addresses to restart a trial is not permitted. When the trial ends, the plugin stops working until a licence is purchased.

Restrictions

You may not:

• Reverse engineer, decompile, or disassemble the software, except to the extent applicable law expressly permits it despite this restriction
• Resell, rent, sublicense, or distribute the software to third parties
• Share your account or let other people use your licence
• Circumvent or tamper with licence verification, trial limits, or update signature checks
• Remove or modify any licence notices or proprietary markings
• Use the software for any unlawful purpose

Licence Verification & Internet Connection

The software verifies your licence or trial against our server. A working internet connection is required at least periodically; if the software cannot reach our server for an extended period, it may stop working until it can connect again. What is sent during verification is described in our Privacy Policy.

30-Day Money-Back Guarantee

If you are not satisfied with a purchase, contact us within 30 days of the purchase date at support@archplug.com and we will refund it in full, no questions asked. When a refund is issued, the licence for that purchase ends. Details: Refund Policy.

Digital Delivery & Right of Withdrawal

Our software is digital content supplied immediately after purchase. If you are a consumer in the European Union or in the Republic of Serbia, you normally have a statutory 14-day right of withdrawal. At checkout you expressly request immediate supply and acknowledge that you thereby lose that right once the licence is delivered. This does not affect our voluntary 30-day money-back guarantee above, which covers you in practice anyway.

Automatic Updates

ArchPlug keeps your plugins up to date on its own, so that a fix does not require you to re-install anything. A small background helper (a Windows scheduled task named ArchPlug Updater) is installed together with the plugins. It runs under your Windows user account, also while Revit is closed, and installs new versions released for your account.

• Every update is verified before it is installed: it must be digitally signed by ArchPlug DOO and match the checksum published by our server. Anything that fails either check is discarded and nothing is changed on your computer.
• Only ArchPlug files are replaced. Your Revit installation and your projects are never touched, and nothing from your Revit models is ever sent to us.
• To make sure updates actually arrive, the helper regularly sends our server a technical status report about the ArchPlug installation on that computer. Exactly what it contains is listed in our Privacy Policy.
• Updates may improve, change or replace features and are provided under these same terms. We will not use an update to materially reduce the core function of a plugin you have paid for, except where required by law, security, or a change in Autodesk Revit itself.
• Stopping updates: clearing the email field in ArchPlug Settings and clicking Save stops all updates; as the licence is tied to the account, the plugins stop working too. When you uninstall the ArchPlug plugins, the helper removes itself within about an hour. If you need help, write to support@archplug.com.

Error Reports

If a plugin encounters an error, it may ask whether you want to send an error report. Nothing is sent unless you agree, and you can change that choice at any time in ArchPlug Settings › Privacy. If you choose “Always send”, the plugins also send usage statistics (which plugin commands are used and how often); without that choice nothing is counted or sent. Error reports and usage statistics never include your email address, project or file names, or anything from your Revit models. See our Privacy Policy.

AI-Assisted Features

Some ArchPlug products — in particular ArchPlug Agent — and the “Ask AI” chat on this website use a third-party large language model (Anthropic’s Claude). You are interacting with an artificial intelligence system, not a human, and this is disclosed in the interface.

• You are always in control. AI-assisted features only run when you explicitly start them, and any step in progress can be interrupted.
• Output may be wrong. AI-generated results are suggestions, not professional advice. They can be incomplete, inaccurate, or unsuitable for your project. You remain responsible for reviewing and verifying every change before relying on it for design, documentation, construction, permitting, or any other purpose.
• No professional guarantee. We do not warrant that AI-generated output complies with any building code, standard, or regulation.
• Keep backups. As with any tool that modifies a model, save and back up your Revit files before running AI-assisted operations.

Your Responsibility for Project Results

ArchPlug plugins automate drafting and documentation tasks in Autodesk Revit. They do not replace the professional judgement of an architect or engineer. You are responsible for checking the elements, dimensions, tags, quantities and other results the software creates before using them in any drawing, calculation, submission or construction.

Compatibility

Our plugins are designed for Autodesk Revit 2022 through 2027 on Windows. Autodesk Revit is not available for macOS, so there is no macOS version. We make reasonable efforts to support new Revit versions, but cannot guarantee compatibility with versions Autodesk has not yet released. Autodesk and Revit are trademarks of Autodesk, Inc.; ArchPlug is not affiliated with or endorsed by Autodesk.

Updates & Upgrades

Plugin versions follow the MAJOR.MINOR.PATCH scheme. What your licence includes:

• Minor and patch updates (x.Y.z) — bug fixes, stability improvements, smaller features and support for new Revit versions — are free for the lifetime of your licence.
• Major versions (X.0) introduce substantial new functionality and are released as paid upgrades. Existing licence holders are offered major upgrades at 50% off the full price. Your purchased version continues to work regardless, and receives critical fixes for 12 months after a new major version is released.
• If you purchase within 30 days before a new major version is released, you receive that major version at no extra charge.
• Monthly subscriptions (where offered) include all updates — minor and major — for the plugins covered, for as long as the subscription is active.
• Lifetime Bundle purchases cover the plugins included in the bundle at the time of purchase, with free minor/patch updates; major upgrades are offered per plugin at 50% off. The bundle does not include plugins released after the purchase.

Subscriptions

Where a monthly plan is offered, it renews automatically each billing period until cancelled. You can cancel at any time; the subscription stays active until the end of the paid period and is not charged again. When a subscription ends, the plugins it covers stop working. Refunds for renewals are described in our Refund Policy.

Third-Party Components

The software includes third-party open-source components (for example IronPython, licensed under the Apache License 2.0), which remain the property of their respective owners and are provided under their own licences. Nothing in these terms restricts rights you have under those licences.

Warranty

Apart from the statutory rights described below, the software is provided "as is". We do not warrant that it will be uninterrupted or error-free, or that it suits every project or workflow — which is why a free trial is available before you buy.

If you are a consumer, you have statutory rights regarding digital content that conforms to its description (for example under the consumer protection law of Serbia or of your EU country of residence). Nothing in these terms excludes or limits those rights.

Limitation of Liability

To the maximum extent permitted by law, ArchPlug is not liable for indirect, incidental, special or consequential damages, including loss of data, corruption or loss of Revit project files or models, loss of profits, or business interruption. Our total liability for any claim relating to the software is limited to the amount you paid for the licence concerned in the twelve months before the claim.

These limitations do not apply to damage caused intentionally or through gross negligence, to injury to life or health, or to any liability that cannot be limited under applicable law, including mandatory consumer protection law.

Termination

You may stop using the software at any time. We may suspend or end your licence if you materially breach these terms (for example by sharing an account, reselling the software or circumventing licence checks); where the breach can be remedied, we will first ask you to do so. A licence also ends when its purchase is refunded or charged back, or when a subscription ends. After termination you must stop using the software.

Governing Law & Disputes

These terms are governed by the laws of the Republic of Serbia, and the competent court in Belgrade has jurisdiction. If you are a consumer, you also keep the protection of the mandatory laws of your country of residence and may bring a claim before the courts where you live. Please contact us first at support@archplug.com — most issues can be resolved quickly.

Changes to These Terms

We may update these terms, for example when products, the law or our payment provider change. The date at the top shows the latest version. We will notify existing customers by email of material changes at least 14 days before they take effect. Changes do not reduce the scope of a licence you have already paid for.

Miscellaneous

If any provision of these terms is found invalid, the remaining provisions stay in effect. These terms, together with our Privacy Policy and Refund Policy, are the entire agreement about the software. In case of discrepancy between this English text and a translation, the English text prevails, unless mandatory law provides otherwise.
