Product & Download Licence Terms

Last updated: August 2026

These Product & Download Licence Terms govern the use of downloadable software, digital assets, files, tools, and other products made available by Erryn.io Ltd (the Licensor).

They may apply to WordPress plugins, downloadable software and utilities, Blender and procedural assets, models, textures, templates, 3D and fabrication files, development resources, free tools, experiments, and other downloadable digital products (each a Product).

A Product may also include its own licence file, open-source licence, product-specific terms, or licence statement. Where those terms conflict with these terms, the licence expressly stated for that Product takes precedence to the extent of the conflict.

These terms do not apply to hosted software-as-a-service products, which are governed by the erryn.io Software Subscription Terms, or to consultancy and professional services, which are governed by the erryn.io Terms of Business.

1. Definitions

In these terms:

Business Licensee means a Licensee acting wholly or mainly for purposes relating to its trade, business, craft, or profession.
Consumer means an individual acting wholly or mainly outside their trade, business, craft, or profession.
End Product means a finished work, project, production, application, visualisation, render, publication, physical item, or other output incorporating or derived from a Product, but which does not make the original Product or a substantially equivalent editable or extractable version available to the recipient.
Extended Licence means an additional or alternative licence granting rights beyond the Standard Licence, as described on the relevant Product page, Order Confirmation, or licence document.
Fabrication File means a model, drawing, template, toolpath, design, or other digital file intended to be 3D printed, machined, cut, manufactured, fabricated, or otherwise converted into a physical object.
Licensee means the individual, business, or organisation lawfully obtaining or using a Product.
Licensor means Erryn.io Ltd, a company registered in England and Wales under company number 17407419, whose registered office is The Old Granary, Hampton-on-the-Hill, Warwick, United Kingdom, CV35 8HB.
Open-Source Licence means the GNU General Public License or another open-source or free-software licence expressly stated to apply to a Product or component.
Order Confirmation means the checkout confirmation, invoice, receipt, product page, licence certificate, marketplace order, or other record identifying the Product and licence purchased or supplied.
Product means a downloadable digital product made available by the Licensor and covered by these terms.
Product Files means the editable, source, original, packaged, or downloadable files comprising a Product.
Standard Licence means the default licence described in these terms for a proprietary Product unless an Open-Source Licence, Extended Licence, or Product-specific licence applies.

2. Licence hierarchy

The licence applicable to a Product is determined in the following order:

Any Open-Source Licence or other licence expressly included with or stated to govern the Product.
Any Product-specific or Extended Licence stated on the Product page or Order Confirmation.
These Product & Download Licence Terms.

Nothing in these terms is intended to remove, restrict, or replace rights expressly granted under an applicable Open-Source Licence.

3. Open-source software and WordPress plugins

3.1 Open-source Products

Where a Product is supplied under an Open-Source Licence, rights to copy, modify, use, and distribute that Product are governed by that Open-Source Licence rather than the proprietary restrictions elsewhere in these terms.

Any conditions concerning source code, copyright notices, attribution, distribution, modification, or downstream licensing are those imposed by the applicable Open-Source Licence.

3.2 WordPress plugins

WordPress plugins published by the Licensor through the WordPress.org Plugin Directory will be distributed under the GNU General Public License version 2 or later (GPLv2+), or another GPL-compatible licence expressly stated for the relevant Product.

Where GPLv2+ is stated, the Licensee may use, study, modify, copy, and redistribute the covered material in accordance with that licence.

Files included in a Product distributed through the WordPress.org Plugin Directory will be licensed consistently with the applicable WordPress.org licensing requirements.

3.3 Trademarks remain separate

An Open-Source Licence governing copyright in software or other files does not grant ownership of the Licensor’s trade names, trademarks, service marks, branding, or commercial identity.

The names erryn.io, Erryn.io Ltd, LucroForge, and any other Product names, logos, or branding belonging to the Licensor may not be used in a way that falsely suggests sponsorship, endorsement, affiliation, or that a modified or redistributed Product is an official version published by the Licensor.

This does not prevent reasonable descriptive or nominative reference to the original Product or its origin.

3.4 Modified open-source versions

Where an Open-Source Licence permits redistribution of modified versions, the Licensee is responsible for complying with that licence and for making clear where reasonably required that modifications were not made or approved by the Licensor.

The Licensor is not responsible for faults, vulnerabilities, incompatibilities, or other issues introduced by a modified or third-party redistributed version which differs from the version officially published by the Licensor.

4. Proprietary downloadable software and tools

This clause applies to downloadable software, utilities, applications, scripts, tools, or similar Products that are not governed by an Open-Source Licence.

4.1 Licence grant

Under the Standard Licence, the Licensor grants the Licensee a non-exclusive, worldwide, non-transferable licence to install and use the Product for personal or internal business purposes, subject to any device, user, site, installation, or other limits stated for that Product.

4.2 Restrictions

Unless an applicable licence expressly permits it, the Licensee must not:

Sell, redistribute, sublicense, rent, lease, or provide the Product itself to another person.
Make the Product available as part of a competing download, software library, asset pack, repository, or distribution service.
Remove or deliberately obscure copyright, authorship, or licence notices contained within the Product.
Circumvent licence keys, activation restrictions, usage limits, technical protection measures, or similar controls.
Reverse engineer, decompile, or disassemble proprietary software except to the extent that applicable law gives the Licensee a right which cannot lawfully be excluded.

5. Digital assets

This clause applies to Blender files, procedural assets, materials, models, textures, templates, graphics, presets, node systems, design resources, and similar proprietary digital assets.

5.1 Standard Licence

Unless the relevant Product states otherwise, the Standard Licence permits the Licensee to use and modify the Product in personal and commercial projects and to incorporate it into End Products.

Permitted uses may include renders, animations, visualisations, websites, games, applications, advertising, films, publications, client projects, presentations, and other finished creative or commercial work.

No royalty is payable to the Licensor from revenue earned from a permitted End Product.

5.2 Source and editable files

The Standard Licence does not permit resale, redistribution, sharing, sublicensing, or publication of the Product Files themselves, whether modified or unmodified.

A Licensee may not make an asset available in a form from which the original or substantially equivalent Product can readily be extracted and reused as a standalone asset.

Modification of a Product does not by itself create a right to redistribute the modified Product Files.

5.3 Client projects

The Standard Licence permits use of a Product in work created for a client, provided the client receives the resulting End Product rather than reusable Product Files.

If editable or reusable Product Files need to be transferred to the client, the client must obtain an appropriate licence or the Licensee must hold an Extended Licence expressly permitting that transfer.

5.4 Attribution

Attribution is not required for proprietary Products under the Standard Licence unless the Product page or accompanying licence expressly states otherwise.

This does not permit removal of copyright or licence information embedded within Product Files where those files are otherwise lawfully transferred.

6. Extended Licences

An Extended Licence may grant additional rights for a particular Product.

Those rights are defined by the Product page, Order Confirmation, licence certificate, or other written terms supplied when the Extended Licence is obtained.

Depending on the Product, additional rights may include:

Use across additional organisations, users, installations, or client accounts.
Transfer of editable files to a client.
Use within certain products intended for resale.
Commercial manufacture and sale of physical items derived from a Fabrication File.
Other redistribution or commercial rights expressly identified for that Product.

No additional right should be assumed merely because an Extended Licence has been purchased. Only the rights expressly stated for that Extended Licence are granted.

7. 3D and Fabrication Files

7.1 Standard Licence

Unless the Product page states otherwise, a Standard Licence for a Fabrication File permits the Licensee to manufacture physical objects from the file for personal use, prototyping, testing, demonstration, internal business use, or use as part of a commissioned project.

The Standard Licence does not automatically permit the manufacture of physical copies primarily for resale as a product line.

Where commercial manufacture and resale of physical items is permitted, this will be expressly stated on the Product page or granted through an Extended Licence.

7.2 Digital redistribution

Permission to fabricate a design does not include permission to sell, share, publish, or redistribute the underlying Fabrication File, including a modified version of that file, unless expressly stated otherwise.

7.3 Fabrication and engineering responsibility

Fabrication Files are supplied as digital designs. Unless a Product expressly states otherwise, they have not been certified for any particular structural, safety-critical, medical, load-bearing, automotive, aerospace, electrical, protective, regulatory, or other controlled application.

The suitability and performance of a fabricated object can depend on matters outside the Licensor’s control, including material selection, manufacturing method, machine calibration, tolerances, orientation, settings, scaling, post-processing, assembly, environmental conditions, modification, and the intended application.

The Licensee is responsible for evaluating those factors and for carrying out appropriate testing, engineering review, validation, certification, and regulatory compliance before relying on a fabricated object or supplying it to another person.

A Fabrication File must not be relied upon for a safety-critical purpose solely because the Product can physically be manufactured or appears suitable for that purpose.

8. Artificial intelligence and machine learning

This clause applies only to proprietary Products and does not restrict rights granted under an applicable Open-Source Licence or rights which cannot lawfully be excluded.

Unless an applicable Product licence expressly permits it, the Standard Licence does not permit the Product Files, or a substantial reproduction of them, to be used:

To train or fine-tune a generative machine-learning or artificial-intelligence model intended to reproduce the Product or substantially similar assets.
As part of a training dataset assembled for that purpose.
To create a model, service, or asset-generation system whose principal purpose is to substitute for or redistribute the Licensor’s Product library.

This clause does not prohibit ordinary use of a Product within a creative workflow merely because an AI-assisted tool is also used in that workflow, provided the Product itself is not used as prohibited training material.

9. Free tools and experiments

A free tool, experiment, utility, prototype, demonstration, or similar Product may be provided without charge under the Standard Licence unless another licence is expressly stated.

The Licensor may modify or discontinue a free proprietary Product at any time and does not undertake to provide ongoing updates, compatibility, development, or support unless expressly stated otherwise.

If a free Product is supplied under an Open-Source Licence, rights in copies already obtained continue to be governed by that licence.

10. Third-party components

A Product may incorporate software, libraries, fonts, textures, models, data, code, or other materials supplied by third parties.

Where a third-party component has its own licence, that licence governs use of that component. Nothing in these terms gives the Licensee greater rights in third-party material than the Licensor is entitled to grant.

Where reasonably practicable, applicable third-party licence notices will be included with the Product or documentation.

11. Updates, compatibility and support

11.1 Compatibility

Where a Product page identifies compatible software, platforms, versions, file formats, hardware, or other requirements, those statements relate to the Product version available at that time unless expressly stated otherwise.

The Licensor does not guarantee indefinite compatibility with future versions of operating systems, WordPress, Blender, browsers, third-party plugins, development environments, manufacturing software, hardware, or other external technology.

11.2 Updates

Unless an Order Confirmation or Product page expressly includes an update entitlement, purchase or download of a Product does not create an obligation for the Licensor to provide future feature updates indefinitely.

This does not affect any obligation which applicable consumer law requires in relation to the Product supplied.

11.3 Support

Support is included only where stated on the Product page, Order Confirmation, or applicable licence.

Community or voluntary support provided for free Products does not create a contractual response-time or continued-support commitment.

11.4 Keeping copies

Unless ongoing cloud download access is expressly included with a purchase, the Licensee is responsible for keeping reasonable backup copies of Product Files it is entitled to retain.

The Licensor does not guarantee that every historic version or download will remain permanently available from erryn.io or a third-party marketplace.

12. Ownership

Except for rights owned by third parties and rights expressly granted under an Open-Source Licence, the Licensor retains ownership of all copyright and other intellectual property rights in its Products.

Purchasing or downloading a proprietary Product grants a licence to use it. It does not transfer ownership of the underlying intellectual property.

Ownership of an End Product created by the Licensee is unaffected, subject to the Licensor retaining its rights in any underlying Product incorporated into it.

12.1 Feedback

If the Licensee voluntarily provides suggestions, bug reports, feature ideas, or other feedback concerning a Product, the Licensor may use that feedback without restriction or payment.

This does not give the Licensor ownership of the Licensee’s confidential information or independently created intellectual property.

13. Orders, pricing and delivery

Where a Product or Extended Licence is sold directly by the Licensor, the applicable price and licence will be displayed before purchase or stated in the Order Confirmation.

Unless expressly stated otherwise, prices are exclusive of VAT where VAT is legally applicable.

Erryn.io Ltd is not currently VAT registered. VAT will be charged if and when legally required.

Digital delivery normally occurs by immediate download, download link, account access, repository access, email, marketplace delivery, or another electronic method identified when ordering.

14. Consumer purchases and cancellation rights

This clause applies where a Licensee purchases a Product as a Consumer. Nothing in these terms excludes or restricts statutory consumer rights which cannot lawfully be excluded or restricted.

14.1 Immediate digital delivery

Where a Consumer asks to receive downloadable digital content immediately rather than waiting until the end of any applicable cancellation period, the checkout process may ask the Consumer to:

Expressly consent to supply of the digital content beginning immediately; and
Acknowledge that the statutory right to cancel will be lost once supply of the digital content begins where applicable law provides for that consequence.

Where the required consent and acknowledgement have validly been given and supply has begun, the Consumer may lose the statutory cancellation right relating to that digital download.

Where the legal requirements for loss of that right have not been satisfied, the Consumer retains any cancellation rights provided by applicable law.

14.2 Consumer quality rights

Nothing in these terms removes a Consumer’s statutory rights concerning digital content, including rights which may apply where digital content is not of satisfactory quality, fit for a particular purpose made known to the trader, or as described.

15. Refunds

Subject to clause 14 and any other right that cannot lawfully be excluded, fees for a proprietary digital Product or licence are normally non-refundable once the Product has been supplied or the relevant licence rights have been made available.

This does not prevent a refund or other remedy where:

The payment was duplicated or charged incorrectly.
The Licensor agrees otherwise in writing.
The Product is subject to statutory rights or remedies which cannot lawfully be excluded.

Where a Product was purchased through a third-party marketplace, refund administration may also be subject to the marketplace’s applicable purchasing and refund process.

16. Warranty

16.1 Consumers

Nothing in this clause limits rights or warranties which applicable consumer law requires and which cannot lawfully be excluded.

16.2 Business Licensees

For Business Licensees, and except where expressly stated otherwise, proprietary Products are supplied as available and without warranties beyond those which cannot lawfully be excluded.

The Licensor does not warrant that every Product will:

Be suitable for every particular project or purpose.
Operate without interruption, error, or incompatibility.
Remain compatible with future third-party software, platforms, hardware, or file formats.
Be free from every possible defect or security vulnerability.
Produce a particular commercial, creative, technical, manufacturing, or other outcome.

16.3 Open-source Products

Open-source Products are subject to the warranty terms and disclaimers contained in their applicable Open-Source Licence, together with any rights which applicable law does not permit to be excluded.

17. Liability

17.1 Consumers

Nothing in this clause excludes or limits liability to a Consumer where doing so would be unlawful. Any limitation applying to a Consumer is subject to applicable consumer protection law and the requirement for contractual terms to be fair.

17.2 Free proprietary Products supplied to Business Licensees

Subject to clause 17.5, the Licensor’s total aggregate liability to a Business Licensee arising out of or in connection with a proprietary Product supplied entirely free of charge is limited to £50.

17.3 Paid proprietary Products supplied to Business Licensees

Subject to clause 17.5, the Licensor’s total aggregate liability to a Business Licensee arising out of or in connection with a paid Product or licence is limited to the total amount paid by that Licensee to the Licensor for the specific Product or licence giving rise to the claim.

17.4 Excluded business losses

Subject to clause 17.5 and to the fullest extent permitted by law, the Licensor is not liable to a Business Licensee for:

Indirect or consequential loss.
Loss of profit, revenue, anticipated savings, goodwill, reputation, or business opportunity.
Loss caused by incompatibility with a third-party update, platform, plugin, application, device, file format, or service outside the Licensor’s reasonable control.
Loss resulting from modification of a Product by the Licensee or another person.
Loss resulting from use of a Product outside its documented or reasonably apparent purpose.
Loss resulting from the Licensee’s failure to maintain reasonable backups of its own systems, work, or Product Files.
Loss resulting from fabrication, manufacture, material selection, testing, certification, assembly, or use of a physical object produced from a Fabrication File.

17.5 Liability that cannot be excluded

Nothing in these terms excludes or limits liability for:

Death or personal injury caused by negligence.
Fraud or fraudulent misrepresentation.
Any statutory consumer right which cannot lawfully be excluded or restricted.
Any other liability which cannot lawfully be excluded or limited.

18. Licence breaches and termination

18.1 Proprietary Products

Where the Licensee materially breaches the licence applying to a proprietary Product, the Licensor may give written notice requiring the breach to stop or be remedied within 14 days where it is reasonably capable of remedy.

The Licensor may terminate the proprietary licence if the material breach is not remedied within that period.

For deliberate unauthorised redistribution, sale, sublicensing, circumvention of licensing controls, or other infringement that cannot reasonably be remedied, the Licensor may terminate the licence immediately.

18.2 Effect of termination

Following termination of a proprietary licence, the Licensee must stop making new use of the Product and must not create, distribute, sell, or supply further copies of the Product or new End Products incorporating it.

Unless the breach involved unlawful creation or distribution of the End Product itself, termination does not require destruction of lawful End Products genuinely completed and supplied before termination.

Any continuing rights expressly granted under a Product-specific agreement remain subject to that agreement.

18.3 Open-source licences

This clause does not alter the grant, continuation, termination, reinstatement, or downstream effect of rights under an Open-Source Licence. Those matters are governed solely by the applicable Open-Source Licence.

19. Third-party marketplaces and directories

A Product may be obtained through a third-party directory, marketplace, repository, or distribution platform including WordPress.org.

Use of that third-party platform may also be subject to its own terms, privacy policy, purchasing rules, refund procedures, or account requirements.

Those platform terms govern the Licensee’s relationship with the platform. The intellectual property licence applying to the Product itself remains determined in accordance with clause 2.

20. General

20.1 Governing law

These terms are governed by the laws of England and Wales.

For Business Licensees, the courts of England and Wales have exclusive jurisdiction over disputes arising from these terms.

If the Licensee is a Consumer, this clause does not deprive the Consumer of any mandatory protection or right to bring proceedings available under applicable consumer law.

20.2 Changes

The Licensor may update these terms from time to time.

Unless another licence expressly provides otherwise, an updated version applies to proprietary Products first obtained after the updated terms take effect.

An update to these terms does not retrospectively reduce perpetual proprietary licence rights already validly granted under an earlier version.

Open-source Products remain governed by their applicable Open-Source Licences.

20.3 Assignment

A proprietary licence may not be transferred to another person or organisation unless the applicable Product licence permits transfer or the Licensor agrees in writing.

This does not restrict redistribution or transfer rights expressly granted under an Open-Source Licence.

20.4 Severability

If any provision of these terms is found to be invalid or unenforceable, the remaining provisions continue in effect.

The affected provision will, where legally possible, be modified only to the minimum extent necessary to make it valid and enforceable.

20.5 Waiver

A failure or delay by the Licensor to exercise a right does not waive that right.

20.6 Entire agreement

For a proprietary Product, these terms together with the Product page, Order Confirmation, any Extended Licence, and any Product-specific licence expressly incorporated into the purchase constitute the agreement concerning the licence to that Product.

For an Open-Source Product, the applicable Open-Source Licence governs the rights which it grants.

Nothing in this clause excludes liability for fraud or fraudulent misrepresentation.
