SimpleDiagrams Cloud Service and Shape Licence

This SimpleDiagrams Cloud Service and Shape Licence (Licence) forms part of the SimpleDiagrams Cloud Terms. It explains the rights granted to a Customer to access the proprietary hosted software, use SimpleDiagrams-supplied SDShapes, and distribute finished diagram output. Defined terms have the meaning given in the Terms.

This Licence applies to SimpleDiagrams Cloud. The artwork supplied with SimpleDiagrams Desktop, and the shape libraries we offer for download from this website for use in it, are licensed under the SimpleDiagrams Shape License, which is included in the Desktop App, is published on this website, and uses the same artwork terms as this Licence. When you download a library while signed in, you agree to that Shape License for the library. It does not grant access to the Desktop App itself, which is bought separately on the Mac App Store or directly from this website and is governed by the SimpleDiagrams Desktop Licence Agreement. The products do not currently interoperate, and no diagram import, transfer, or sync is available between them.

1. What is licensed

Platform Materials include:

• the hosted SimpleDiagrams Cloud application and its user interfaces;
• APIs, agent interfaces, schemas, component registries, and documentation;
• SDShape definitions, renderers, behaviours, state schemas, icons, illustrations, artwork, and other reusable semantic components;
• SDShapes and collections or libraries supplied by us; and
• updates, improvements, and derivative Platform Materials supplied by us.

Platform Materials are licensed, not sold. McQuillen Interactive and its licensors retain the intellectual property rights they hold in them. We grant permission only to the extent we own the relevant rights or are authorised to license them. We do not claim that copyright or another exclusive right exists in every individual shape, symbol, or element.

How the shapes were made

The original shapes in the SimpleDiagrams 4 libraries were drawn by hand, and some of them have since been redrawn with AI. Many later shapes, including additions to some of those libraries, were drawn by AI models to our direction: mainly Claude, made by Anthropic, and also Codex, made by OpenAI. The AI models wrote the drawing code and geometry that produce these shapes, and we reviewed and selected each shape for appearance and fit. That review is not a legal clearance. A library can therefore contain both hand-drawn and AI-made shapes. The libraries that contain AI-made shapes are: Basic, Biz, UI Flow, and Value Stream, which add AI-made shapes to their original hand-drawn ones; and Aged Care, Aged Care 2, Azure, BPMN, Building Monitoring, Cooking, Data Centers and AI, Green Walls, Hobby Electronics, Hobby Electronics Notebook, Home Energy Efficiency, HVAC, Insurance, Regenerative Farm Isometric, Regenerative Farm Plan, Regenerative Farm Plan (Watercolor), Solar & Battery Sites, Solar & Battery Sites 2, Tool & Die, and UML, in which every shape is AI-made. A library released on or after 23 October 2026 says in its library information whether it contains AI-made shapes.

You may use every supplied SDShape as Section 3 allows, however it was made. Because the law on AI-made material is still developing, some shapes may not be protected by copyright. We therefore cannot promise that you will have exclusive rights in a shape, or that you could register a shape, or a design based on one, as a trademark. We cannot see what material the AI models learned from, so we cannot guarantee that no shape resembles someone else's work. If your use needs artwork that is guaranteed to be human-made, exclusive, or cleared of all third-party rights, please use other material. We do not provide an intellectual property indemnity unless we agree to one in writing.

Some shapes may depict a third-party logo, brand, or product, or a protected emblem such as the Star of Life. Your use of such a mark or emblem is your responsibility, and this Licence does not grant any right in it. You are also responsible for what you add to a diagram and for how you use the finished diagram, including any logos, names, or likenesses you include. If someone tells you that a shape copies their work, please let us know as described in Section 11.

2. Service access grant

Subject to the Terms, the AUP, payment of applicable fees, and plan limits, we grant Customer a limited, non-exclusive, non-transferable, non-sublicensable right during an authorised trial or paid subscription period to access and use the Service for Customer's internal operations and to create, share, display, publish, and export diagrams for Customer's lawful business, educational, personal, marketing, sales, editorial, and creative purposes.

Authoring rights are limited to the number of author seats in the plan. Customer may permit employees, contractors, students, clients, and other authorised people to view diagrams without a paid author seat where the applicable visibility and access rules permit. Customer may not provide authoring access as a service bureau whose principal value is resale of access to SimpleDiagrams without a separate written agreement.

3. Licence for SimpleDiagrams-supplied SDShapes

During authorised use, we grant Customer a worldwide, royalty-free licence to use, arrange, resize, recolour where supported, label, modify, configure, animate, and combine SimpleDiagrams-supplied SDShapes within a finished diagram. Customer may reproduce and distribute finished diagrams and exports in electronic or print media, including:

• internal dashboards, reports, presentations, documentation, and training;
• websites, shared or exported diagrams, advertising, marketing, and sales material;
• educational material, books, editorial publications, packaging, and merchandise;
• video, film, broadcast, and social media; and
• work produced for Customer's clients as part of a broader professional service.

These uses may be commercial. No attribution is required for a supplied SDShape covered by this Licence unless its library entry expressly says otherwise. A finished diagram remains a permitted output even if its file format technically contains an embedded or vector representation of a supplied SDShape, provided the purpose is to communicate the diagram rather than to distribute a reusable SDShape asset.

A shape library you download from this website while signed in is licensed to you under the SimpleDiagrams Shape License for use in SimpleDiagrams Desktop. That licence continues after your account closes, for the copy you already hold.

Customer may share an editable SimpleDiagrams document with another authorised SimpleDiagrams user for genuine collaboration on that diagram. An editable document is not a prohibited library merely because it contains supplied shapes, provided its purpose is to communicate or edit the diagram rather than distribute reusable assets. Customer retains any independently protectable contribution it makes when modifying a shape; the modification does not transfer underlying rights or permit distribution of the modified shape as a reusable asset.

4. SDShape and library restrictions

Customer must not, except where applicable law does not permit the restriction:

• extract, scrape, download in bulk, republish, sell, sublicense, transfer, or distribute a supplied SDShape, definition, renderer, or library as a standalone or substantially reusable asset;
• use supplied SDShapes or definitions to create or train a competing stock-art, component, icon, template, or diagram-shape library;
• make source assets available in a form intended to let recipients edit, extract, or reuse them independently of the finished diagram;
• remove a required attribution, provenance, licence, copyright, or trademark notice;
• use a supplied SDShape, or a confusingly similar adaptation, as a trademark, service mark, logo, or source identifier without separate written permission;
• claim ownership of a supplied SDShape or suggest that McQuillen Interactive endorses Customer or the subject represented by an SDShape; or
• circumvent plan, export, access, or technical controls protecting Platform Materials.

Customer may make reasonable cached, backup, and working copies automatically created through ordinary authorised use. This does not grant a right to maintain a mirror of the Platform Materials or make them available after access ends, except for a downloaded library copy licensed to Customer under Section 3 or within a finished diagram already lawfully exported or published during authorised use.

Downloading a library that we offer for download, for your own use, is permitted and is not the bulk downloading this section forbids. You may not pass a downloaded library on to anyone else.

5. Customer and third-party shapes

Customer retains ownership of original shapes, artwork, definitions, and libraries it creates or submits as Customer Content through supported features. This does not promise support for asset uploads, customer-defined shape definitions, or executable renderers. Customer grants us the limited Customer Content licence in the Terms so we can store, validate, render, display, and deliver them. Customer is responsible for securing all necessary rights and for accurately recording licence, provenance, and attribution information.

A third-party shape or library is governed by the licence displayed with that item, not by Section 3 of this Licence. If a third-party licence conflicts with this Licence, the third-party licence controls only that third-party material. We may remove or disable material where its provenance or rights cannot be verified.

6. Customer diagrams and exports

As between the parties, Customer owns the original selection, arrangement, labels, configuration, state data, and other Customer-created expression in its diagrams, to the extent those contributions are independently protectable, and subject to underlying rights in Platform Materials and third-party content. Publishing a diagram publicly does not transfer those rights or apply an open-content licence.

The licence to previously created finished outputs is perpetual, provided the output was created during authorised use and Customer continues to comply with the shape-use restrictions. After termination, Customer may continue displaying and distributing those outputs. Customer may not use termination as a means to retain or redistribute an extracted library or source component collection.

7. Software restrictions

Customer must not:

• copy or operate the hosted application outside the Service;
• sell, rent, lease, sublicense, or provide the Service itself to a third party;
• reverse engineer, decompile, disassemble, or attempt to discover non-public source code or algorithms, except to the limited extent a law makes that restriction unenforceable;
• modify, bypass, or disable authentication, billing, entitlement, or security controls;
• use non-public interfaces or misleadingly imply compatibility or endorsement; or
• use Platform Materials to build a service whose primary purpose competes with the core hosted diagram-authoring, semantic-shape, or live-diagram functionality.

These restrictions do not prohibit independent integration with documented APIs, development of a competing product without misuse of Platform Materials, or exercise of rights granted by an applicable open-source licence.

8. Open-source components

The Service uses third-party open-source software, including Excalidraw. Those components are governed by their own licences and notices in the application's third-party notices. This Licence does not reduce rights granted by an open-source licence. The SimpleDiagrams Cloud hosted service, semantic component definitions, proprietary renderers, and SimpleDiagrams-owned artwork are not made open source merely because an open-source component is used to render or edit a scene.

9. Trademarks and publicity

“SimpleDiagrams,” associated logos, and product trade dress are our marks. Customer may truthfully state that it uses SimpleDiagrams, but may not use our marks in a way that suggests sponsorship or forms part of Customer's own product name, domain, or logo. We will not use Customer's name or logo in marketing without permission.

10. Term and effect of termination

This Licence starts when Customer first accepts the Terms and continues while Customer has authorised access. Paid authoring, API, agent, and source-asset rights end when the applicable subscription ends. During the limited lapsed period described in the Terms, Customer retains only the access we make available for supported viewing, export, and resubscription. During a planned Service Closure, Customer retains only the supported access we make available to export Customer Content until the notified closure date. The continuing licence for a downloaded library copy in Section 3 is not ended by account closure or the end of a Cloud subscription. All Service access ends when the account or organisation is closed. Sections concerning ownership, restrictions, finished outputs, open-source rights, and terms that by nature should survive will survive.

11. Supplied artwork: warranties, liability, and rights complaints

Nothing in this Licence excludes, restricts, or modifies a guarantee, right, or remedy under the Australian Consumer Law or another law that cannot lawfully be excluded. Where applicable law permits a limitation to replacement, repair, resupply, or payment of the corresponding cost, we may limit the relevant remedy only to the extent that doing so is lawful and fair and reasonable.

Other than those guarantees and our express promises in this Licence, we do not promise that a supplied shape is free of third-party rights or will meet every legal or commercial requirement of a particular use, and supplied shapes and libraries are otherwise provided as is. This does not limit an express permission in this Licence.

Subject to those non-excludable rights and remedies, to the maximum extent permitted by law, neither party is liable under this Licence for indirect, incidental, special, exemplary, or consequential loss, or for lost profit, revenue, goodwill, opportunity, or anticipated savings, arising from supplied shapes or libraries. This exclusion does not apply to fraud, wilful misconduct, a breach of Section 4, or infringement of the other party's intellectual property rights. A library being free does not, by itself, remove liability or reduce a statutory remedy to zero.

Subject to the non-excludable rights and remedies above, to the maximum extent permitted by law, our total aggregate liability to you arising from supplied shapes and libraries in the 12 months ending on the date of the event giving rise to the claim is limited to the greater of AUD 100 and the amount you paid during those 12 months for the affected shapes, libraries, and applicable SimpleDiagrams application licence or Cloud subscription, including amounts paid through an authorised seller. This is one aggregate cap, not a separate cap for each claim or shape. The cap does not apply to fraud, wilful misconduct, infringement of the other party's intellectual property rights, or liability that cannot lawfully be limited. It does not limit a statutory remedy that the law requires us to provide.

Customer remains responsible for material it adds, changes it makes, and unlawful uses it chooses. Customer is not required to defend or indemnify us merely because a claim concerns a supplied shape used as we permit, including as resized, recoloured, combined, or otherwise modified as this Licence permits, except to the extent the claim arises from material Customer added. Such a claim does not, by itself, trigger Customer's indemnity in the Terms. Using a supplied shape as this Licence permits does not breach this Licence, the Terms, or the AUP merely because the supplied shape itself is found to infringe another person's rights. Nothing in this Licence binds a third-party rights holder or prevents a claim by that person.

If you receive a rights complaint concerning a supplied shape, please contact us promptly with the library name, shape name, and the complaint details. Rights holders may also contact us at support@simplediagrams.com. Our Copyright Complaints Policy explains what a complaint should contain and how we handle it. We will assess the report and may stop distributing, replace, or revise affected artwork. If a change affects your use, we will explain the available steps and any applicable remedies. If we tell you that a shape has been withdrawn after a rights complaint, please stop making new uses of it; we will offer a replacement where we can or, for a paid library, an appropriate remedy. This process does not limit statutory rights or promise that already distributed diagrams can be recalled.

This section applies to supplied artwork whether bundled with SimpleDiagrams or downloaded separately, free or paid. It also applies to AI-assisted and AI-generated artwork. For a claim to the extent it concerns supplied artwork, the warranty and liability provisions in this section apply in place of Sections 12 and 13 of the Terms, including their loss exclusions and monetary cap. The Terms continue to govern claims concerning the Cloud Service itself. The two monetary caps do not accumulate for the same loss. The continuing permissions for finished outputs and downloaded copies remain subject to this Licence and applicable law.
