1. OVERVIEW

Welcome to Kadmium (https://www.kadmium.dev), engineered and operated by Emil Fredrik Sjöstedt ("Kadmium", "we", "us", or "our"). This website serves as the official portal, documentation repository, service engine, and distribution platform for our Unreal Engine 5 (UE5) C++ architecture audits, technical consulting services, developer utilities, software tools, and video games.

By accessing or browsing this website, booking technical advisory services, purchasing source code or software licenses, downloading compiled applications, or playing our games, you agree to be bound by these Terms of Service. Your use of our website and services is also governed by our [Privacy Policy], which explains how we collect and protect your data.

2. SERVICES, PURCHASES & COMMERCE FRAMEWORK

Kadmium operates under a dual-commerce framework depending on the type of product or service acquired:

• Direct B2B Consulting, Audits & Commercial Retainers (Stripe & Wise): Direct technical engagements—including C++ Architecture Audits, Performance Diagnostics, Engineering Blocks, Monthly Retainers, and Direct Enterprise Licensing—are processed via Stripe, Inc. or direct business wire transfers (Wise). For these transactions, Kadmium acts as the direct seller and service provider. Invoices automatically process applicable European Union VAT (via B2B Reverse Charge where valid Tax IDs are supplied).

• Self-Serve Digital Goods & Merchant Sales (Gumroad): For standalone downloadable digital products, small-scale source code tiers, or self-serve tools purchased directly through our website, Gumroad, Inc. acts as our authorized Merchant of Record (MoR), handling checkout execution, billing, customer invoicing, and global sales tax/VAT compliance.

• Third-Party Marketplaces (Epic Games Store / Fab / Steam): If you license or acquire our plugins, assets, or games through third-party platforms, the transaction, order delivery, and storefront terms are governed entirely by that specific platform’s agreements.

Applicable License & Service Contracts:

• Consulting & Audits: Governed by the terms specified at checkout, invoice statements, or executed Non-Disclosure/Service Agreements (NDAs).

• Developer Tools & Source Code: Governed strictly by our Software & Source Code License Agreement.

• Video Games: Governed strictly by our End User License Agreement (EULA).

3. REFUNDS, SCHEDULING & ORDER FULFILLMENT

3.1 B2B Technical Consulting & Engineering Services:

• Advisory Calls & Audits: Services that have been scheduled, executed, or delivered (such as completed repository code audits, custom diagnostic reports, or conducted strategy calls) are final and non-refundable. Cancellations or rescheduling requests for live calls must be made at least twenty-four (24) hours prior to the scheduled slot.

• Monthly Retainers: Retainer subscriptions are billed in advance per billing cycle. Unused monthly advisory hours do not roll over to subsequent months and are non-refundable.

3.2 Digital Goods, Source Code & Compiled Tools:

• Source Code: Because downloadable source code solutions consist of uncompiled, irrevocable digital intellectual property, all direct source code sales are final and strictly non-refundable once download links or repository access have been granted.

• Compiled Applications: Refund requests for compiled commercial binaries are evaluated in accordance with our Software & Source Code License Agreement (generally within 14 days, provided the license has not been abused), unless governed independently by a third-party storefront’s native policy.

4. INTELLECTUAL PROPERTY

All content hosted on this website, distributed in our technical audit reports, embedded in our tool suites, and compiled into our games—including text, brand marks, logos, user interfaces, C++ source code, architectures, shaders, art assets, and audio—remains the exclusive intellectual property of Kadmium (Emil Fredrik Sjöstedt) or its respective licensors.

Disclaimer: Unreal Engine® is a registered trademark of Epic Games, Inc. Kadmium is an independent software and technical consultancy studio and is not directly affiliated with, sponsored by, or endorsed by Epic Games, Inc.

5. TELEMETRY & DIAGNOSTICS

Our compiled tools, launcher services, and video games may include opt-in or anonymized technical telemetry (such as crash dump reporting and basic web analytics) solely for stability diagnostics, frame-rate profiling, and security patching. We do not harvest, track, or sell personally identifiable user information (PII). For complete details, please review our Privacy Policy.

6. USER COMMUNICATIONS, CODE REPOSITORIES & FEEDBACK

When submitting bug reports, repository access links, architecture proposals, or technical inquiries via our contact channels:

• Code Submissions: You warrant that submitted codebase files, logs, or materials do not contain malicious code, spyware, or unauthorized third-party trade secrets.

• NDAs vs. General Feedback: Confidential code submitted under a signed NDA for a paid audit remains strictly confidential. However, any general technical suggestions, workflow concepts, or feature requests you submit regarding our public tools, frameworks, or games may be integrated into future iterations without any obligation, royalty, or compensation owed to you.

7. DISCLAIMER & LIMITATION OF LIABILITY

7.1 "As-Is" Provision: This website, our technical advisory reports, developer tools, frameworks, and games are provided on an "as-is" and "as-available" basis without warranties of any kind, whether express or implied.

7.2 Limitation of Liability: To the maximum extent permitted by applicable Swedish and European Union law, Kadmium shall not be held liable for any indirect, incidental, punitive, special, or consequential damages (including loss of revenue, loss of data, engine downtime, or business disruption) resulting from the use of, reliance upon, or inability to use our website, software, or technical consulting advice.

7.3 Liability Cap: In all circumstances (including B2B consulting engagements), Kadmium’s maximum aggregate liability shall be strictly limited to the actual amount paid by you to Kadmium for the specific product or service giving rise to the claim during the twelve (12) months preceding the claim.

8. RIGHT TO REFUSE SERVICE & MODIFICATIONS

• Refusal of Service: Kadmium reserves the right to refuse service, terminate consulting engagements, or cancel orders at our sole discretion (e.g., in cases of payment fraud, harassment, or project scope mismatch), subject to refunding any unfulfilled prepaid consulting hours.

• Modifications: We reserve the right to update, modify, or replace these Terms of Service at any time. Continued use of the website or our services following the posting of any changes constitutes acceptance of those changes.

9. GOVERNING LAW & JURISDICTION

These Terms of Service are governed by and construed in accordance with the substantive laws of Sweden, harmonized with applicable European Union regulations. Any dispute, controversy, or claim arising out of or in connection with these Terms shall be settled exclusively by the general courts of Sweden, with the Stockholm District Court (Stockholms tingsrätt) serving as the court of first instance.
