STUDENT LICENSE AGREEMENT

Acceptance

This Student Licence Agreement ("Agreement") is a legally binding contract between Spherene AG, Europa-Str. 9, CH-8152 Glattbrugg (ZH), Switzerland ("Spherene AG", "we", "us") and the individual student ("you", "Student", "Licensee") accessing or using the Spherene platform under a free student subscription.

By registering for a student account, ticking the "I agree" checkbox at signup, or accessing any part of the SphereneNXT Platform or using a Spherene Plugin, you confirm that you have read, understood, and agree to be bound by this Agreement in its entirety, together with the Spherene AG Master Subscription Agreement, Terms of Use, and Privacy Policy, each incorporated by reference. In the event of conflict between this Agreement and the MSA, the MSA prevails.

IMPORTANT — READ BEFORE ACCEPTING: This licence is provided completely free of charge. The consideration you provide in exchange for free access is the broad, perpetual data and usage licence granted to Spherene AG in Section 6. These rights survive account closure, graduation, and termination of this Agreement. Section 6 is a material and non-negotiable condition of the free licence. If you do not agree to Section 6, do not register — paid subscription options without these extended data rights are available at spherene.io/pricing.

1. Eligibility

1.1 Who qualifies

The Student Licence is available to individuals currently enrolled as students at an accredited educational institution — meaning a university, college, polytechnic, or technical school formally registered with national or regional education authorities (such as Swiss SBFI, German KMK, UK QAA, or US regional accreditors) or holding official accreditation from a recognised accreditor. The following do not qualify: corporate training facilities, bootcamps, for-profit training organisations, online-only course platforms, consulting firms, or unaccredited private institutions.

1.2 Verification

To activate a Student Licence you must provide a valid institutional email address. Spherene AG may request within 15 business days official documentation confirming current enrolment status (enrolment letter, valid student ID). Spherene AG verifies eligibility before activation and may re-verify annually or where usage patterns suggest enrolment has ended.

1.3 Change of enrolment status

This licence is valid only during active enrolment. Upon graduation, withdrawal, suspension, or any other change in enrolment status, your right to access the Platform ceases. It is your responsibility to notify Spherene AG at support@spherene.io of any change. Spherene AG's data rights under Section 6 are not affected by any change in your enrolment status and continue in full force after you leave the institution.

2. Licence Grant

Subject to your compliance with this Agreement and continued eligibility under Section 1, Spherene AG grants you a limited, non-exclusive, non-transferable, revocable, royalty-free licence during the period of your active enrolment to access and use:

• Spherene desktop software (all student-tier features);

• SphereneNXT cloud-based SaaS platform via web browser and API;

• Spherene plugins and integrations, including Rhino/Grasshopper, Autodesk Fusion, and nTop where available under the student tier;

• the Spherene Customer Portal for licence management, account settings, and support.

The specific features and usage thresholds available under the student tier are published at spherene.io/pricing/students-plan and may be updated by Spherene AG from time to time.

3. Permitted Use

You may use the Platform solely for the following non-commercial academic purposes:

• coursework, assignments, lab work, and degree-requirement projects;

• personal academic learning and skill development;

• thesis or dissertation work in fulfilment of your enrolled degree;

• non-commercial academic research intended for peer-reviewed or academic publication;

• participation in academic competitions or student challenges where no direct financial gain is received.

Student internships and research-assistant positions are permitted even if compensated by the institution or external academic grants, provided the work is non-confidential, publishable, and supervised by faculty at an accredited institution.

4. Restrictions

4.1 Prohibited activities

You must not:

• use the Platform for any commercial, consulting, paid, or revenue-generating work;

• perform work for or on behalf of a commercial entity in exchange for any form of compensation, equity, or financial benefit;

• create deliverables — designs, analyses, reports, or outputs — intended for external customers or commercial products;

• share, sublicense, rent, or distribute the Platform or your credentials to any other person;

• allow any other person to use your account;

• reverse-engineer, decompile, disassemble, or attempt to derive source code, algorithms, or computational logic of the Platform;

• modify, translate, or create derivative works from the Platform or its proprietary algorithms;

• use the Platform to develop, train, or benchmark any tool, algorithm, or service directly competing with Spherene AG's core capabilities in topology optimisation, minimal-surface design, or lattice generation, except as permitted under Section 4.2;

• use the Platform from any embargoed territory or for the benefit of any sanctioned person or entity;

• remove or obscure any proprietary notices or attribution statements.

4.2 Academic AI and machine-learning research

You may use Platform outputs as training data or input for academic AI/ML research provided: (a) the research is for a degree requirement or peer-reviewed publication; (b) the primary intent at the time of creation is non-commercial; and (c) the work does not result in a directly competing commercial product. If your intended use is ambiguous, contact legal@spherene.io before proceeding.

5. Citation and Acknowledgement

If you use the Platform or its outputs in any paper, thesis, presentation, or publication, you must acknowledge Spherene AG as follows:

"This work was conducted using Spherene (www.spherene.io) for [specify application: topology optimisation / ADMS / lattice design / heat dissipation analysis / other]."

For blind peer review, you may omit the citation from the submission and must add it to the final published version. Failure to cite constitutes a material breach of this Agreement.

6. Data and Usage Rights

Section 6 sets out the rights you grant to Spherene AG as the sole consideration for free access to the full Spherene platform. These rights are intentionally broad. They are legally grounded in your freely given, specific, and informed consent under GDPR Article 6(1)(a) and Swiss nDSG, and in the performance of this Agreement under GDPR Article 6(1)(b). They survive account closure, graduation, and termination. Read this section carefully before accepting.

6.1 Perpetual data licence — the consideration for free access

In consideration for the free licence granted in Section 2, you grant Spherene AG an irrevocable, perpetual, worldwide, royalty-free, sublicensable licence to access, copy, store, process, analyse, use, and exploit your Customer Data — including all design files, geometry, CAD data, metadata, simulation inputs and outputs, and any other content you upload, submit, or generate through the Platform — for any of the following purposes:

• product research, improvement, optimisation, and feature development;

• development, training, fine-tuning, benchmarking, and validation of machine-learning models, neural networks, generative AI systems, and any other artificial intelligence systems, whether or not related to the specific designs you submitted;

• algorithm research and development, including developing and improving Spherene AG's core ADMS, topology optimisation, and minimal-surface computation technology;

• quality assurance, performance testing, bug identification, and platform security;

• internal analytics, business intelligence, and strategic planning;

• academic and scientific research, including potential collaboration with third-party research institutions, subject to Section 6.3;

• demonstration, marketing, and promotional activities, using anonymised or aggregated data only; and

• any other internal purpose related to the development, improvement, commercialisation, or operation of Spherene AG's products, services, and business.

6.2 Survival after account closure and graduation

The licence granted in Section 6.1 is perpetual and irrevocable. It continues in full force after:

• your account is closed for any reason;

• you graduate or leave your educational institution;

• this Agreement is terminated for any reason, including termination by Spherene AG;

• you request deletion of your personal data under Section 7.

The legal basis for continued use after account closure is your advance, informed consent given at the time of acceptance, which constitutes valid consent under GDPR Art. 6(1)(a) and Swiss nDSG for this specific, clearly described purpose. You understood at the time of acceptance that the licence would survive account closure, and Spherene AG relied on that grant in providing you with free access.

6.3 Sublicensing to sub-processors

Spherene AG may sublicense your Customer Data to its authorised sub-processors (as listed in the Privacy Policy at spherene.io/legal/privacy-policy) solely for the purposes in Section 6.1. Sub-processors are bound by data protection obligations at least as protective as those in Spherene AG's Data Processing Agreement. Spherene AG will not sell your identifiable Customer Data to third parties for their independent commercial use.

6.4 Trained model weights and AI outputs

Any machine-learning model weights, neural network parameters, trained algorithms, generative AI outputs, or other computational artefacts developed by Spherene AG through training on your Customer Data or Usage Data are the exclusive property of Spherene AG. These trained outputs are not personal data, are not subject to any deletion right under GDPR Art. 17 or Swiss nDSG, and are retained by Spherene AG permanently. Deletion of your personal data or Customer Data under Section 7 does not affect, diminish, or require modification of any trained model weights derived from that data.

6.5 Usage Data

Spherene AG automatically collects Usage Data — anonymised, aggregated technical and behavioural data including login timestamps, session duration, features used, design complexity metrics, computation times, error logs, and device information. Usage Data is owned exclusively by Spherene AG, may be used for all purposes in Section 6.1, and is retained by Spherene AG indefinitely, including after account closure. Usage Data collection is integral to platform operation and cannot be opted out of.

6.6 Anonymisation standard

Where Spherene AG uses Customer Data for marketing, external publication, or third-party disclosure, it will do so in anonymised form. Data is anonymised when your name, email address, institutional affiliation, and project title have been permanently and irreversibly removed, and no combination of reasonably available datasets could re-identify you or your institution. Spherene AG will not publish or disclose individually identifiable designs in recognisable form without your prior written consent.

6.7 Your ownership of original files

You retain ownership of your original, independently created design files and Customer Data. The licence in Section 6.1 does not transfer ownership of your underlying intellectual property to Spherene AG. Spherene AG owns all improvements, enhancements, trained models, and derivative works it independently creates using insights from your data. Where a work is jointly created, the parties will discuss attribution in good faith.

6.8 Personal data processing

Personal data you provide (name, email address, institutional affiliation, device identifiers) is processed in accordance with the Privacy Policy at spherene.io/legal/privacy-policy and applicable data protection law including Swiss nDSG and GDPR. Personal data is used solely for licence account management, eligibility verification, support communications, renewal reminders, and compliance monitoring. Personal data is not shared with third parties for their own marketing without your explicit consent. The legal basis for processing personal data is performance of this Agreement (GDPR Art. 6(1)(b)) and, where applicable, legitimate interest (Art. 6(1)(f)).

7. Data Retention and Your Deletion Rights

Your deletion rights under GDPR Art. 17 and Swiss nDSG apply to personal data and identifiable Customer Data. They do not apply to anonymised data, Usage Data, or trained model weights. The perpetual licence in Section 6.1 continues to apply to anonymised design data retained by Spherene AG after personal data deletion.

7.1 What Spherene AG retains and for how long

The following table describes what data Spherene AG holds, who holds it, and for how long:

• Personal identifying data (name, email, affiliation): Held by Spherene AG. Retained for the duration of the licence plus 6 months after account closure for legal compliance. Deleted on valid request under Section 7.2, subject to any mandatory legal retention obligations.

• Identifiable Customer Data (design files, project metadata with your identity attached): Held by Spherene AG. Retained for the duration of the licence. On account closure, retained for 30 days to allow your export. After 30 days, identifiable links are stripped and files are either deleted or anonymised per Section 7.3.

• Anonymised Customer Data (geometry, design patterns, outputs with identity removed): Held by Spherene AG. Retained indefinitely under the perpetual licence in Section 6.1. Not subject to deletion rights once anonymisation is complete.

• Usage Data (technical and behavioural analytics): Held by Spherene AG. Retained indefinitely. Not personal data once aggregated and anonymised. Not subject to deletion.

• Trained model weights and AI outputs derived from your data: Held by Spherene AG. Retained permanently. Not personal data. No deletion right applies. See Section 6.4.

7.2 Your right to request deletion of personal data

You may at any time request deletion of your personal data and identifiable Customer Data by emailing privacy@spherene.io with the subject line "Data Deletion Request — [Your Name]". Spherene AG will: (a) acknowledge within 5 business days; (b) complete deletion or anonymisation within 30 days; and (c) provide written confirmation of what was deleted and what was retained in anonymised form. The following will be deleted: CAD files and design uploads linked to your identity, project names, descriptions, and metadata, and your personal identifiers. The following will be retained: anonymised geometry and design patterns, aggregated usage statistics, and trained model weights.

7.3 Anonymisation rather than deletion

Where Spherene AG determines that a Customer Data file has value for AI/ML training or product development, Spherene AG may, instead of deleting the file, permanently strip all identifying information and retain the anonymised geometry under the perpetual licence in Section 6.1. Once a file is anonymised to the standard in Section 6.6, it is no longer personal data and is no longer subject to any deletion right. Spherene AG will inform you in its deletion confirmation whether files were deleted or anonymised.

7.4 On graduation or departure

On notification that you have graduated or left your institution, or on annual re-verification failure: (a) your platform access is suspended; (b) you have 30 days to export your files via the Customer Portal; (c) if you are completing a thesis or publication you may request a 12-month extension by emailing support@spherene.io before the 30-day window closes; (d) after the 30-day window (or approved extension), identifiable data is deleted or anonymised per Section 7.3; and (e) anonymised data and model weights are retained by Spherene AG permanently under Section 6.1.

8. Intellectual Property

All intellectual property in the Platform — source code, algorithms, ADMS technology, computational logic, data models, trade secrets, documentation, and trademarks — is the exclusive property of Spherene AG as set out in the Master Subscription Agreement at spherene.io/legal/master-subscription-agreement. Nothing in this Agreement transfers any Spherene AG intellectual property rights to you. The Platform is licensed, not sold.

You retain ownership of independently created design files. Spherene AG owns all improvements, trained models, and derivative computational works it develops using your data under Section 6.1. You acknowledge that Spherene AG's algorithms and ADMS technology are trade secrets protected indefinitely, and you will not attempt to reverse-engineer, replicate, or disclose them.

9. Term and Termination

9.1 Term

This Agreement commences on the date you accept it and continues for the duration of your active enrolment, subject to annual re-verification. The data licence in Section 6.1 survives termination permanently.

9.2 Termination by Spherene AG

Spherene AG may suspend or terminate your Platform access immediately if you: are no longer enrolled; provide false enrolment information; use the Platform for commercial or paid work; share credentials or allow others to use your account; breach Sections 4, 5, or 8; violate export control or sanctions law; or fail to provide verification documents within 15 business days of request.

9.3 Termination procedure

Non-remediable violations (fraud, false information, intentional breach): access suspended within 24 hours, written notice within 5 business days. Other breaches: written notice specifying the breach, 15-day cure period. If uncured, access revoked. Your institution may be notified of the reason for termination in all cases.

9.4 Effect of termination on Platform access

On termination of Platform access: (a) your right to access and use the Platform ceases; (b) any locally downloaded software must be deleted; (c) the 30-day data export window in Section 7.4 opens; and (d) accrued obligations survive. Sections 5, 6, 7, 8, 10, 11, and 12 survive termination permanently.

10. Export Control and Sanctions

You must comply with all applicable Swiss, EU, UK, and US export control, sanctions, and embargo laws. You must not use or access the Platform from any embargoed territory or for the benefit of any sanctioned person or entity. By accepting this Agreement you certify that you are not located in an embargoed jurisdiction and are not subject to any applicable sanctions list. Violation constitutes a material breach resulting in immediate termination without cure period.

11. Disclaimers and Limitation of Liability

11.1 No warranty

THE PLATFORM IS PROVIDED "AS IS" AND FREE OF CHARGE. SPHERENE AG MAKES NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.

11.2 Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SPHERENE AG SHALL NOT BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO THIS AGREEMENT OR YOUR USE OF THE PLATFORM, INCLUDING LOSS OF DATA OR ACADEMIC WORK. BECAUSE THE PLATFORM IS PROVIDED FREE OF CHARGE, SPHERENE AG'S AGGREGATE LIABILITY SHALL NOT EXCEED CHF 100. THESE LIMITATIONS DO NOT APPLY TO DAMAGES CAUSED BY SPHERENE AG'S WILFUL MISCONDUCT OR FRAUD.

12. Governing Law and Dispute Resolution

This Agreement is governed by Swiss law, excluding conflict of laws rules and the CISG. Disputes shall first be subject to good-faith negotiation for 30 days. If unresolved, disputes shall be submitted to the exclusive jurisdiction of the courts of Zurich, Switzerland, subject to mandatory consumer-protection provisions applicable in your country of residence. Educational institutions may request good-faith mediation in Zurich or Geneva before litigation.
