Intellectual Property Policy

Effective date: 6 November 2026

1. Scope and ownership This policy covers software, branding, project stories, architectural and engineering drawings, photographs, product catalogues, specifications, CAD/BIM files, reviews, RFQs, AI inputs and outputs. Rights remain with their lawful owners according to applicable law and relevant contracts. Lighthouse owns or licenses its platform code, interface, original platform content and other protectable assets. Users do not acquire those rights merely by using the service. Conversely, uploading material does not assign the user’s or a third party’s intellectual property to Lighthouse. No table or label in this policy determines authorship or ownership contrary to statute, employment terms, an assignment or a licence.

2. Licence to operate the service The uploader grants a non-exclusive, royalty-free licence to host, reproduce, format, transmit, display, index and process content only as needed to provide the requested service, respect the chosen visibility, secure the service and comply with law. Subcontractors may exercise those rights only as necessary service providers under appropriate restrictions. Public portfolio display is authorised only for content deliberately submitted for public publication. Private plans, quotations, RFQs, prices, invoices and enterprise files remain private to the authorised participants and necessary providers. Separate recorded permission is needed for standalone advertising, investor presentations, off-platform campaigns or case studies outside the authorised service context. General model training is not included in the service licence. The AI Policy governs any separately authorised training. This licence ends on deletion except for limited backup cycles, required evidence or other lawful retention. Retained material cannot be commercially republished or used for training merely because a copy remains. This clause replaces the source draft’s perpetual and irrevocable licence over all uploads.

3. Architecture, design and technical files Owning a building or paying for design services does not automatically establish ownership of every drawing, photograph or model. Check the appointment, employment, commission, assignment and photographer agreements. A project may involve several firms and contributors. State the actual role of each credited party, do not claim exclusive authorship without basis, and obtain approval for collaborative portfolio use where needed. Client permission to show a premises does not necessarily cover its photography or confidential design files.

Do not remove watermarks, copyright notices or provenance; reuse confidential tender information; distribute editable BIM/CAD files beyond the licence; or use plans to clone another party’s protected work. Project product tags must distinguish confirmed installed products from illustrative recommendations. AI concepts do not establish ownership of an actual building’s design.

4. Product, brand and commercial material A manufacturer, distributor or reseller must have authority for the images, trademarks, manuals and specifications it submits. Authorisation to sell a product is not automatically a right to sublicense every photograph or brand asset. Use brand marks accurately to identify genuine goods or a permitted relationship. Do not imply endorsement or authorised-dealer status without evidence. Technical facts may be treated differently from protected creative expression; no blanket ownership claim covers all factual product information. Private RFQs, quotations and negotiated prices must not be republished, supplied to competitors or used to build a commercial dataset outside the authorised purpose.

5. AI, datasets and feedback AI processing does not transfer ownership of an input. Rights in output depend on applicable law, human contribution and relevant provider terms; no guarantee of exclusivity, copyright eligibility or non-infringement is made. Similar outputs may be provided to others. Do not use unlicensed content for training or represent a synthetic image as proof of completed work. Preserve legally required labels and technical provenance. Independently assess sensitive or commercially important output before publication or use. Lighthouse may create genuinely aggregated or irreversibly anonymised operational statistics where lawful, but must not claim ownership of customer material merely by describing it as marketplace intelligence or a knowledge graph. Pseudonymisation does not eliminate privacy obligations. Voluntary feedback may be used to improve the service on a non-exclusive, royalty-free basis, excluding confidential material and underlying third-party works unless separately authorised. Feedback is not a vehicle for transferring a client’s designs.

6. Other rights and lawful exceptions Do not infringe trademarks, patents, registered designs, trade secrets or contractual confidentiality. Do not bypass access controls, extract protected databases, distribute licensed software or reverse engineer unlawfully. Nothing here prevents a use allowed by mandatory law, a valid open-source licence, fair dealing or other applicable exception. An allegation should identify the right and conduct involved; similarity alone does not prove infringement.

7. Complaints, counter-statements and remedies Copyright claims follow the Copyright Policy; trademark claims follow the Trademark Policy. For patents, designs, trade secrets or disputed ownership, send the right identified, relevant registration or contractual evidence, exact content locator, explanation and authority to act through the grievance contact. We may restrict material while reviewing credible risk, seek evidence and give the respondent a fair opportunity to explain where lawful. Decisions may include attribution correction, removal, listing restrictions or account action. An internal decision is not a ruling on legal title. Affected users may submit a counter-statement and seek human review under the Content Moderation & Takedown Policy. Statutory and judicial remedies remain available. Reporting fraudulently or using takedowns to suppress lawful competition is prohibited.

8. Retention and updates Complaint evidence is retained only for the required purpose and legal period with restricted access. No unlimited rights-holder portal or priority service is promised. Updates are published with appropriate notice and cannot retrospectively enlarge a licence over existing content without lawful authorisation.

9. Separate rights in a construction project A project can contain independently owned architectural drawings, photographs, text, product renders, software files, logos, music and confidential know-how. Ownership of a building, purchase of a product or payment of a design fee does not automatically transfer every intellectual-property right in those materials. Contributors must identify their actual contribution and respect employment, commissioning and collaboration arrangements. A contractor may show work it performed only within the applicable publication permissions; it must not claim authorship of the architect’s design. Disputed credits should be reviewed using contracts, source files and other relevant evidence.

10. Precise scope of the platform licence The service-use licence includes technically necessary copies, formatting, translations approved for the feature, thumbnails, indexing and distribution through the selected Lighthouse visibility settings. For a public completed-project profile, this includes showing the approved project in relevant discovery results and resurfacing it to users within the service while the permission remains valid. It does not permit sale of standalone photographs, licensing to unrelated advertisers, public release of private plans or unrestricted use to train general models. Independent campaigns, investor decks, external case studies and third-party syndication require the separately recorded permission described in the Terms.

The licence extends to service providers only to perform the authorised task, under equivalent restrictions. A change in provider does not expand the purpose. A corporate transfer of the service must preserve the user’s contractual and privacy rights.

11. Older content, archives and withdrawal Before recirculating old material, check the original grant, current visibility, expiry, credits, confidentiality and any withdrawal or dispute. Refresh factual context without pretending that a past project is new. An old permission to publish once in a particular channel is not necessarily permission for repeated worldwide promotion. On deletion or expiry, stop new authorised public uses and remove controlled copies under the relevant procedure. Limited legal archives and backups must not be reused commercially. A third party’s lawful possession of a copy does not create an open licence for Lighthouse to continue republishing it.

12. AI output, model rights and confidential information Ownership of AI output may depend on law, human contribution, inputs and provider terms. Lighthouse does not promise exclusivity, copyright registration or non-infringement merely because the output was generated by a paid feature. Similar outputs may be generated for others. Private plans and quotations remain restricted even if they contain uncopyrightable facts. Trade-secret and confidentiality obligations are separate from copyright. Do not upload another party’s proprietary details to an AI provider without authority and an approved processing arrangement. No licence to patents, registered designs or protected construction methods is granted merely by showing a completed project. A product recommendation does not clear patent rights in a destination market.

13. Platform materials, scraping and permitted access Lighthouse retains its rights in its software, original editorial material and protected compilations, excluding third-party material. Users may use the service and share permitted links as intended. Commercial bulk extraction, republishing a directory, resale of contact lists and model training on protected platform material require permission unless a non-waivable legal right applies. Restrictions must not be interpreted to override lawful interoperability, accessibility or other mandatory exceptions. API access grants only the data-use rights expressly stated in the approved API terms and underlying content permissions.

14. International interpretation and claims Moral rights, database rights, employee-created works and commissioned works differ by jurisdiction. Do not rely on a blanket moral-rights waiver where it is ineffective; obtain specific permitted editorial consent and maintain attribution. Territorial rights and licence limits must be checked before international use.

Copyright, trade mark, design, patent, confidentiality and privacy complaints require different evidence and remedies. Use the relevant route and obtain legal review where title is contested. Contractual indemnities apply only within the relevant agreement and do not themselves establish that a rights claim is valid.

15. Rights matrix for permitted uses For each material asset, distinguish permission to store privately, publish in a profile, display in Lighthouse discovery, translate or edit, include in external advertising, syndicate to another platform and use for model development. Approval of one purpose does not approve the others. Where the agreed service licence already permits ordinary in-service display, this policy does not require repeated consent for every unchanged display within that scope. A rights record should identify restrictions and expiry triggers and travel with the asset when it is moved between internal systems. A marketing team must not infer advertising permission from the fact that an image exists in the public catalogue.

16. Editorial work and approval Lighthouse may make authorised technical formatting and accessibility changes without claiming authorship of the underlying work. Material factual or creative alterations require the permission appropriate to their scope. A rewritten project story must not invent client quotations, awards, design intent, budgets or materials. Where a user approves a story, approval concerns the identifiable version and authorised assets. Corrections to an error may be made promptly, with the relevant contributor informed where appropriate. Substantial new promotional claims require their own review.

17. Confidential technical and commercial material A confidential BOQ, supplier quote, drawing or method statement may be protected by contract or confidence even where particular facts are not copyrightable. Access for comparison does not authorise disclosure to competitors, publication of negotiated prices or sale of a market-intelligence dataset. Recipients may use disclosed material only for the authorised evaluation or performance purpose. They must protect it from unrelated staff and subcontractors and return, delete or restrict it when the purpose ends, subject to applicable records duties. Independently developed information and lawful public facts are assessed on their actual source, not assumed from a similarity.

18. Commissioned deliverables and ownership transfers Any assignment of newly commissioned writing, software, drawings or other deliverables must be set out in the relevant signed agreement with the rights, consideration, territory, duration and other legally required particulars. This public policy does not itself execute an assignment. Background tools, reusable templates, third-party materials and open-source components must be distinguished from commissioned deliverables. The receiving party needs the necessary continuing use rights for embedded material, but does not automatically own the

supplier's entire toolkit. Moral rights and other non-waivable protections remain subject to applicable law.

19. Database, API and machine-readable access An API licence or export permission must identify the permitted records, purpose, storage and onward recipients. Technical ability to download data does not establish a right to republish a directory, train a model or build competing contact lists. Underlying contributor restrictions continue to apply. Lawful interoperability, accessibility, research and other mandatory exceptions are preserved. A claim concerning extraction should identify the protected interest and disputed conduct, rather than assert ownership of all public facts.

20. Open licences and third-party notices A user relying on an open licence must comply with its attribution, share-alike, source-disclosure or other applicable conditions. “Free to view” is not the same as an open licence. A licence permitting editorial use may not permit advertising. Lighthouse may retain required third-party notices with authorised content. Removal of a notice to simplify a design is not permitted where the notice is a condition of use. Conflicting licence conditions should be resolved before publication.

21. Exit, corporate changes and continuing use A transfer of an account, business or platform does not enlarge the original rights grant. The successor may use content only within the lawful transferred rights and applicable privacy obligations. Material changes to purpose require a fresh basis. After expiry or withdrawal, new exploitation must stop within the applicable process. Limited retained evidence cannot be reused as an active content library. A claim for surviving fees or confidentiality does not create perpetual promotional rights over the other party's work.
