Legal
End User Licence Agreement
The agreement between you and Neosphyr Ltd covering use of the software.
Neosphyr Ltd
Version 1.1 · Effective 5 October 2026
1. About this agreement
1.1 Who we are
This Software is licensed to you by Neosphyr Ltd, a company registered in England and Wales under company number 17473213, whose registered office is at 71–75 Shelton Street, Covent Garden, London WC2H 9JQ, United Kingdom ("we", "us", "our").
You can contact us at info@neosphyr.com.
1.2 What this agreement covers
This End User Licence Agreement ("Agreement") is a legal agreement between you and us. It governs your use of our software plug-ins for Autodesk® Revit®, together with any documentation, updates and online licensing services supplied with them (the "Software").
The Software comprises the following products, licensed individually:
- Model Inspector
- BWIC Extractor
- Parameter Exchange
- Avatar
- BWIC Compliance
By installing, activating or using the Software, you accept this Agreement. If you do not accept it, do not install or use the Software.
1.3 If you are a consumer
Some parts of this Agreement apply only if you are a consumer — an individual acquiring the Software wholly or mainly for purposes outside your trade, business, craft or profession. Those parts are marked "Consumers only". If you are acquiring the Software for the purposes of a business, including as a sole practitioner or freelancer acting in the course of business, the parts marked "Business customers only" apply to you instead.
Nothing in this Agreement affects your statutory rights. If any term conflicts with a right you have under the Consumer Rights Act 2015 or the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, your statutory right prevails and that term does not bind you.
1.4 Other documents that apply
This Agreement should be read together with our Terms of Service, which govern our website and the purchase process, and our Privacy Policy, which explains how we handle personal data including data the Software sends to us. Where this Agreement and the Terms of Service conflict in relation to the Software, this Agreement prevails.
2. The licence we grant you
2.1 Grant
Subject to your compliance with this Agreement and to your licence being active and in good standing, we grant you a non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the Software.
2.2 Seats
Licences are sold with a number of seats:
| Plan | Seats |
|---|---|
| Individual | 1 |
| Multi User | 3 |
| Business | 10 |
| Corporate | 25 or more, under a separately negotiated agreement |
Each seat entitles one named individual to use the licensed product. Seats are personal to the individual they are assigned to: they may not be shared, pooled between people, or used on a concurrent or floating basis.
Every seat must be assigned to a named individual, and that individual must be you or — if you are a business — your employee, or a contractor working under your direction. Seats may not be assigned to anyone outside your organisation, including clients, a parent, subsidiary or associated company, or a joint-venture partner, unless we agree otherwise in writing.
2.2A Telling us who the named individuals are
Where a plan carries more than one seat, you tell us the name of each individual holding a seat when you place your order, and you keep that information accurate for as long as the licence lasts. Write to info@neosphyr.com when a name changes.
We may ask you to confirm the current list of named individuals once in any twelve-month period. We ask only for names and, where you choose to give them, work email addresses; we explain in our Privacy Policy what we do with that information and how we tell those individuals about it.
You may permanently reassign a seat to a different individual when the original holder leaves the role for which the seat was purchased. You may not rotate seats between people to serve more users than you have seats for.
2.3 Activation and devices
Activating a seat binds it to the device on which it is activated. Each seat may be activated on up to two devices — for example a desktop workstation and a laptop — provided both are under the control of the individual holding the seat.
The Software enforces this allowance as a single total number of activations for the whole licence, equal to the number of seats multiplied by two. That total is a technical ceiling, not a further entitlement. It exists so that each named individual can work on two machines. It does not entitle you to let the Software be used by more individuals than you have seats for, and using the remaining activations to give additional people access is a breach of this Agreement even though the Software will not stop it.
If you need to move a seat to a replacement device, deactivate it from the current device within the Software, or contact us at info@neosphyr.com.
2.4 Each product is licensed separately
Each of the products listed in clause 1.2 is licensed separately. A licence for one product does not entitle you to use another.
2.5 Corporate agreements
Where we have entered into a separately negotiated written agreement with you for a Corporate licence, that agreement prevails over this Agreement to the extent of any conflict. This Agreement continues to apply in respect of anything that agreement does not cover.
2.6 Permitted use
You may use the Software for your own internal business or professional purposes, including on projects you carry out for your clients.
2.7 Features and limits
A plan may carry limits on what the Software will do, including limits on the number of rows a single export may contain. Any such limits are described at https://www.neosphyr.com/pricing and are applied by the Software when it verifies your licence.
We may add new plans. We will not reduce the features, or tighten the limits, applicable to a plan you have already paid for, during the period you have paid for.
3. What you must not do
3.1 Restrictions
You must not, and must not permit anyone else to:
(a) copy the Software except as strictly necessary for backup or for normal use;
(b) rent, lease, lend, sell, sub-license, distribute or otherwise make the Software available to any third party;
(c) circumvent, disable or interfere with any licensing, activation, authentication or technical protection measure in the Software, including by altering your device clock, tampering with stored licence tokens, or using the Software without a valid licence;
(d) obtain or attempt to obtain more than one free trial of the same product, including by using multiple email addresses or altering your device's hardware identifiers;
(e) modify, adapt or create derivative works from the Software, except as permitted by clause 3.2 or clause 3.3;
(f) remove, obscure or alter any copyright, trade mark or other proprietary notice in the Software;
(g) use the Software to develop a competing product, or to benchmark it for publication without our prior written consent;
(h) use the Software in any way that is unlawful, or that infringes the rights of any third party.
3.2 Your statutory rights to decompile and observe
Nothing in clause 3.1 restricts any right you have under sections 50A, 50B and 50BA of the Copyright, Designs and Patents Act 1988 to make a back-up copy, to decompile the Software where necessary to obtain information required to create an independent program that can interoperate with it, or to observe, study and test its functioning in order to determine the ideas and principles underlying it.
Before exercising a right to decompile for interoperability, we ask — but do not require — that you contact us at info@neosphyr.com, as we may be able to supply the information you need directly.
3.3 Third-party and open-source components
The Software includes third-party components, including open-source components, licensed under their own terms. Those terms are set out in the notices file supplied with the Software and at https://www.neosphyr.com/legal/third-party-notices. Where a third-party licence grants you rights broader than this Agreement, those terms prevail in respect of that component.
4. Compatibility and system requirements
4.1 Supported versions of Revit
The Software supports the following versions of Autodesk® Revit®:
Revit 2024 · Revit 2025 · Revit 2026 · Revit 2027
The Software runs on Microsoft Windows only. Full system requirements are published on our Downloads page.
4.2 What compatibility means
We do not warrant that the Software will work with any version of Revit, operating system or third-party add-in not listed in clause 4.1. Autodesk® releases new versions of Revit annually and may change its API and its .NET runtime requirements, including between minor updates. We aim to support each new annual release within a reasonable time after its general availability, but we do not guarantee this.
4.3 Withdrawal of support for older versions
We may cease to support an older version of Revit. If we do, we will give you at least 60 days' notice by email, and the version of the Software already installed on your device will continue to work with that version of Revit for as long as it technically can — we will not disable it.
If we withdraw support for the version of Revit you use during a licence period you have paid for, you may cancel and we will refund the unused portion of what you have paid, calculated on a daily basis.
5. Updates and changes to the Software
5.1 Updates we provide
While your licence is active, we will make available updates to the Software, which may include bug fixes, improvements and support for new Revit versions.
5.2 Changes to functionality
We may modify the Software from time to time. We will not, during a period you have paid for, remove a material feature that was part of your plan when you subscribed, unless:
(a) we are required to do so for legal, security or safety reasons; (b) the change is necessary because of a change in a third-party platform on which the Software depends, including Autodesk® Revit®; or (c) we give you at least 30 days' notice and, if the change materially reduces the value of the Software to you, you may cancel and receive a pro-rata refund of the unused period.
6. The free trial
6.1 What the trial is
We offer a free trial of 14 days for each product. To start a trial you provide your email address, name and company name in the Software; the trial licence is issued and activated immediately, without waiting for an email.
The 14 days run from first activation, not from when the trial licence is created.
6.2 What the trial gives you
The trial gives access to the full functionality of the product for its duration.
A trial may also carry usage allowances, which are limits on how much you can do rather than how long you have. Where a product's trial has allowances, they are stated at https://www.neosphyr.com/pricing and shown in the Software, and the trial ends when either the 14 days or an allowance runs out — whichever happens first.
6.3 One trial per product
The free trial is available once per person per product. We use your email address and a hardware identifier to enforce this. Attempting to obtain further trials is a breach of clause 3.1(d).
6.4 When the trial ends
When the trial ends the product stops working until you purchase a licence. Nothing is deleted from your device and no data of yours is affected — the Software simply declines to run until a valid licence is activated.
6.5 This is a trial, not a free plan
The trial is time-limited. We do not currently offer a permanently free version of any product.
6.6 What does not apply to a trial
Clauses 7 (payment), 8 (consumer cancellation) and 9 (refund guarantee) do not apply to a free trial, as no payment is made and no contract for supply at a price is formed.
7. Licences, payment and renewal
7.1 Licence periods
Paid licences are sold as annual subscriptions. Prices are shown in pounds sterling (GBP) at https://www.neosphyr.com/pricing.
7.2 Prices and VAT
Prices shown to consumers include VAT where applicable. Prices shown to business customers may be shown exclusive of VAT, in which case VAT will be added and shown separately before you confirm your order.
7.3 Automatic renewal
Your subscription renews automatically at the end of each period, at the price then in force, unless you cancel before the renewal date. We will send you a reminder by email at least 14 days before each renewal, stating the renewal date and the amount.
7.4 How to cancel
You may cancel at any time through your account at https://www.neosphyr.com/account or by emailing info@neosphyr.com.
There is no notice period. Your cancellation is effective as soon as you make it, which means no further payment will be taken. Your licence then continues, and you keep full access, until the end of the period you have already paid for. We do not refund the remainder of that period on an ordinary cancellation, and you are not required to give a reason.
7.5 Price changes
We may change our prices. Any change applies from your next renewal, never during a period you have paid for. We will tell you at least 30 days before a change takes effect, and you may cancel before the new price applies.
7.6 Failed payments
If a payment fails we will attempt it again and notify you. If payment has not been received within 14 days of the due date we may suspend your licence until payment is made. We will give you notice before suspending.
7.7 Payment processing
Payments are processed by Stripe. We do not receive or store your full card details.
8. Consumer cancellation rights
This clause 8 applies to consumers only, and does not apply to free trials.
8.1 Your 14-day right to cancel
Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 you normally have the right to cancel a distance contract within 14 days of the day the contract is entered into, without giving a reason.
8.2 Losing the right by downloading immediately
The Software is digital content supplied by download. If you ask us to supply it before the end of the 14-day period, and you acknowledge that by doing so you will lose your right to cancel, the right ends once supply begins.
At checkout you are asked to confirm both of these things separately. If you do not give both confirmations, we will not begin supply until the 14-day period has ended.
8.3 How to cancel
Tell us clearly before the period ends — by email to info@neosphyr.com, or using the model cancellation form at https://www.neosphyr.com/cancel. We will refund you within 14 days of being told.
8.4 This does not affect our refund guarantee
Whether or not you still have a statutory right to cancel, our 14-day refund guarantee in clause 9 applies. Clause 9 is a promise we make in addition to your legal rights; it does not replace or reduce them.
9. Our 14-day refund guarantee
This clause applies to all customers, consumer and business. It does not apply to free trials.
If you are not satisfied, tell us within 14 days of the date of your order confirmation email and we will refund what you paid for that licence period in full. You do not need to give a reason, and we will not ask you to return or prove anything.
The guarantee applies to your first paid subscription to a given product. It does not apply to renewals, or to a repeat purchase of a product for which you have already claimed under this guarantee.
Refunds are made to the original payment method within 14 days of your request.
10. How licence checking works, and what the Software sends us
10.1 Licence verification
The Software verifies your licence with our servers. Verification happens when you activate a licence, and periodically while you use the Software. To do this it sends your licence key, a hardware identifier for your device, the product identifier and the software version, and it stores a signed licence token on your device.
This is necessary for the Software to work and cannot be turned off.
10.2 Working offline
The Software continues to work without reaching our servers for 14 days from the last successful verification, so that a site with no connectivity, a closed network or a server outage does not stop you working. The Software attempts to re-verify well before that window expires, so in normal use you will never reach the limit.
For a free trial the offline period is 3 days. It is shorter than the trial itself deliberately: a 14-day offline window on a 14-day trial would double the trial.
If the offline period expires without a successful verification, the Software asks you to connect to the internet before it will run again. Your licence is not cancelled and nothing is lost — it resumes as soon as verification succeeds.
10.3 Usage statistics and error reports
Besides the licence check in 10.1, the Software can send us two further streams. Both are described to you in a panel that appears the first time you press one of our buttons, where you can turn either on or off. You can change that choice whenever you like: open Help and press Usage and diagnostic data.
| What | Default | Your control |
|---|---|---|
| Licence and authentication data | On | Cannot be turned off — see 10.1 |
| Usage statistics — the name of the command you pressed, whether it succeeded, and which versions of Revit and of the Software you run | On | Can be turned off at any time, in the Help window, with no loss of functionality |
| Error and diagnostic reports — the type of a fault and the place in our own code where it happened | Off | Sent only if you switch them on, in the Help window |
What never leaves your computer. Neither stream — nor an error report, if you switch those on — carries file names or project names, folder paths, family, type, parameter or level names, email addresses, your machine name or your own name. Everything that is sent passes through a filter that removes them, both on your computer and again on our servers, and anything that does not come out clean is discarded rather than sent. Your computer is identified by a code derived from its hardware, which cannot be traced back to a person.
The Software never sends the content of your Revit models — no geometry, no parameter values, no drawings, no schedules. Your model data stays on your machine.
We are aware that models you work on are often covered by confidentiality obligations towards your own client. That is the reason for the filter described above, and the reason we would rather send you nothing than risk sending you something of theirs.
Our Privacy Policy explains what is collected, why, how long we keep it, and your rights.
10.4 If we cease trading
If we cease to trade, or permanently discontinue the licensing service, we will use all reasonable endeavours to release a version of the Software that operates without contacting our servers, and to make it available to existing licensees. We will give you as much notice as we reasonably can.
11. Our responsibility to you
11.1 What we promise
We will supply the Software with reasonable care and skill, and we warrant that it will perform substantially in accordance with its documentation.
If you are a consumer and the Software does not meet that standard, you have the remedies given to you by the Consumer Rights Act 2015 — repair or replacement, and then a price reduction where repair or replacement is impossible, not done within a reasonable time, or causes you significant inconvenience. You choose which remedy to pursue, within the framework that Act sets out. We will in any event use reasonable efforts to correct the problem.
If you are a business customer and the Software does not meet that standard, we will at our option use reasonable efforts to correct the problem or refund the amount you have paid for the affected period. This is your sole remedy for breach of the warranty in this clause.
11.2 What we do not promise
We do not warrant that the Software will be uninterrupted or error-free, that it will meet requirements you have not told us about, or that it is compatible with hardware, software or Revit versions not listed in clause 4.1.
11.3 Liability we never exclude
Nothing in this Agreement limits or excludes our liability for:
(a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; (c) any matter for which it would be unlawful to limit or exclude liability.
11.4 Consumers only
We are responsible for loss or damage you suffer that is a foreseeable result of our breach of this Agreement or our failure to use reasonable care and skill. We are not responsible for loss or damage that is not foreseeable.
Nothing in this Agreement excludes or restricts your statutory rights under the Consumer Rights Act 2015, including your rights in respect of digital content that is not of satisfactory quality, not fit for purpose or not as described. No term of this Agreement requires you to do anything, or subjects your rights to any condition, that would make those rights harder to enforce.
If our Software damages your device or other digital content, including your Revit model files, and the damage would not have happened if we had used reasonable care and skill, we will either repair the damage or pay you appropriate compensation, at no cost to you, as section 46 of the Consumer Rights Act 2015 requires.
11.5 Business customers only
Subject always to clause 11.3:
(a) we are not liable to you for loss of profit, loss of revenue, loss of business, loss of anticipated savings, loss of goodwill, business interruption, or any indirect or consequential loss, however arising;
(b) clause 11.5(a) does not exclude our liability for loss of or damage to your Revit model files or other data caused by a defect in the Software or by our failure to use reasonable care and skill. That liability is not excluded; it is limited by the cap in clause 11.5(c);
(c) our total liability to you in respect of all claims arising in any period of twelve consecutive months, whether in contract, tort (including negligence), breach of statutory duty or otherwise, is limited to the greater of (i) the total amount you paid us for the Software in that twelve-month period, and (ii) £1,000,000;
(d) except for the warranties expressly given in clauses 11.1 and 12, and subject to clause 11.5(b), all warranties, conditions and other terms implied by statute or common law are excluded to the extent permitted by law.
11.6 Backing up your work
If you are a business customer: the Software operates on your Revit models. You are responsible for maintaining current backups of your model files and for verifying the Software's output before relying on it. Failure to do so may reduce the loss we are liable for, to the extent the loss could have been avoided.
If you are a consumer: we recommend that you keep backups of your model files and check the Software's output before relying on it. This is a recommendation, not a condition of any right or remedy you have.
The Software is a professional tool. It does not replace your own professional judgement or your obligations to your clients.
12. Intellectual property
12.1 Ownership
The Software is licensed, not sold. All intellectual property rights in the Software, including copyright in the source and object code, remain ours or our licensors'.
Nothing in this Agreement transfers any right in your models, data or project content to us. You retain all rights in those.
12.2 Our warranty
We warrant that we have the right to license the Software to you and that, so far as we are aware, it does not infringe the intellectual property rights of any third party.
12.3 If a claim is made
If a third party claims that the Software infringes their intellectual property rights, we may at our own expense and at our option:
(a) obtain the right for you to continue using the Software; (b) modify or replace the Software so that it is no longer infringing, provided the replacement is materially equivalent in functionality; or (c) if neither is achievable on reasonable terms, terminate the affected licence and refund the unused portion of what you have paid.
12.4 Changes to product and brand names
We may change the name under which the Software or any of its components is marketed. A change of name alone is not a change to functionality and does not entitle you to terminate or to a refund. We will tell you before a name change takes effect and will continue to honour your licence under the new name.
13. Suspension and termination
13.1 Termination by you
You may terminate this Agreement at any time by cancelling your subscription and uninstalling the Software. Cancellation does not entitle you to a refund except as set out in clauses 4.3, 5.2, 8 or 9.
13.2 Termination by us
We may suspend or terminate your licence if:
(a) you materially breach this Agreement and, where the breach can be put right, you do not put it right within 14 days of us asking you to; (b) payment remains outstanding as described in clause 7.6; or (c) we reasonably believe you are using the Software unlawfully, or circumventing its licensing controls.
Except where it would be unlawful or would defeat the purpose of the suspension, we will give you notice and an opportunity to respond before suspending or terminating.
13.3 Effect of termination
On termination you must stop using the Software and remove it from your devices. Clauses 3.2, 3.3, 11, 12, 13.3 and 15 survive termination.
If we terminate without cause, or withdraw the Software entirely, we will refund the unused portion of any period you have paid for.
14. Changes to this Agreement
We may change this Agreement:
(a) to reflect changes in law or regulatory requirements; (b) to reflect changes in the Software or in the third-party platforms it depends on; or (c) for other reasons set out in the notice we give you.
We will give you at least 30 days' notice by email before a change takes effect, unless the law requires it sooner. If a change materially disadvantages you, you may cancel before it takes effect and we will refund the unused portion of what you have paid.
We will not apply changes retrospectively to a period you have already paid for.
15. General
15.1 Assignment
You may not transfer your rights under this Agreement without our written consent. We may transfer our rights and obligations to another business, provided this does not affect your rights. If you are a consumer and we transfer, we will tell you in writing and you may cancel within 30 days and receive a refund of any unused period.
15.2 Third parties
No one other than you and us has any right to enforce this Agreement.
15.3 Severance
If any provision is found unlawful or unenforceable, the remaining provisions continue in force.
15.4 Waiver
If we delay in enforcing this Agreement, that does not prevent us from enforcing it later.
15.5 Entire agreement
This Agreement, the Terms of Service and the Privacy Policy are the entire agreement between us in relation to the Software. Nothing in this clause limits any liability we have for fraudulent misrepresentation. If you are a consumer, nothing in this clause affects information we were required to give you before you bought, which forms part of the contract under section 37 of the Consumer Rights Act 2015.
15.6 Governing law and jurisdiction
If you are a consumer: this Agreement is governed by the law of England and Wales. You may bring proceedings in the courts of England and Wales; if you live in Scotland you may also bring proceedings in Scotland, and if you live in Northern Ireland you may also bring proceedings there. If you live outside the United Kingdom, you keep the benefit of any mandatory consumer protection law of the country where you live.
If you are a business customer: this Agreement and any dispute arising from it are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.
15.7 Notices
Notices under this Agreement are given by email: to you, at the address registered on your account or used to activate your licence; to us, at info@neosphyr.com. A notice sent by email is treated as received at 9.00 am on the next business day after it was sent. It is your responsibility to keep your email address current.
This clause does not apply to the service of court documents.
15.8 Events outside our control
We are not responsible for failure or delay caused by an event outside our reasonable control, including failure of a third-party platform or service on which the Software depends. If such an event occurs we will tell you and take reasonable steps to minimise its effect. If it prevents us from providing the Software for more than 30 consecutive days, either of us may terminate the affected licence and we will refund the unused portion of what you have paid.
15.9 Complaints
If you are unhappy with the Software or our service, contact us at info@neosphyr.com. We will acknowledge your complaint within 5 business days and aim to resolve it within 20 business days.
