4.6 Narrative Architecture & Tactical Combat Advisory

4.6.1 Narrative Development & Ownership. All original narrative architectures, world-building concepts, plot structures, character designs, story bibles and thematic frameworks created by Konstantinos Tsaldaris are the exclusive intellectual property of Kappataf. This includes narratives created entirely from his own creative vision, and narratives developed from a client's general concept or premise, where the client provides the initial idea and Kappataf develops the full narrative structure. In both cases the client receives a non-exclusive, non-transferable license to use the completed narrative work solely for the agreed production. The underlying intellectual property, methodologies and narrative architecture remain the exclusive property of Kappataf.

4.6.2 Creative Development Rights. If you provide an initial story concept, idea or premise, Kappataf retains ownership of all creative development, expansion and refinement of that concept into a full narrative. You may not engage another creator to further develop or expand this narrative without Kappataf's written consent.

4.6.3 Scripts & Story Documentation. All scripts, treatments, outlines, character breakdowns, scene descriptions, dialogue and narrative documentation created during the project are licensed to you for production purposes only. They may not be modified, redistributed or used for competing projects.

4.6.4 Combat Design & Choreography. Tactical combat sequences, fight choreography notes, battle strategies, combat system designs and tactical narratives created for your project cannot be resold, licensed or shared with competing productions. They are project-specific deliverables.

4.6.5 Methodology & Framework. The narrative frameworks, world-building methodologies, character development processes and tactical design systems remain the exclusive intellectual property of Kappataf. They are proprietary tools and may be applied to future projects with other clients.

4.6.6 Derivative Works & Extensions. You may not create, commission or authorize sequels, prequels, spin-offs, expanded universes, derivative works or any narrative extensions based on the story world and concepts created for your project without explicit written permission from Kappataf and additional licensing fees.

Kappataf reserves the right to receive screen credit, production credits and public recognition for narrative architecture, world-building, story conception and tactical combat advisory services provided, including credit in marketing materials, IMDb and official production documentation.

4.6.8 Portfolio & Showcase Rights. Kappataf reserves the right to showcase the narrative work, story concepts and combat designs in portfolio, case studies, industry presentations and educational materials, unless explicitly confidential.

4.7 Infringement Claims

If anyone claims that the Work Product infringes their intellectual property rights, and that claim arises from your requested modifications or specifications rather than from Kappataf's standard methodologies, you agree to indemnify and hold Kappataf harmless from any damages, legal fees or liabilities resulting from such claims.

Kappataf takes data security and client confidentiality seriously. The following measures protect your information and project files.

5.1 Encryption & Transmission Security

• All data transmitted between your device and our servers is encrypted using TLS 1.2 or higher.
• Project files are encrypted in transit and at rest using AES-256 encryption.
• Sensitive information is encrypted and never stored in plain text.

5.2 Access Control & Authentication

• Access to project data requires strong authentication.
• Only authorized personnel with a need to know can view your project files.
• Anyone with access is bound by strict confidentiality agreements.

5.3 Infrastructure Security

• Hosting through secure, industry-certified cloud providers.
• Enterprise-grade firewalls and intrusion detection.
• Regular security patches and software updates.
• DDoS protection and a web application firewall.

5.4 File Transfer & Storage

• Project files are transferred through secure, password-protected channels.
• Encrypted transfer protocols are used: SFTP, or secure cloud links with expiry.
• Large files are virus-scanned before and after transfer.
• Temporary project files are deleted automatically after their retention period.
• You can request permanent deletion of your data at any time, within legal compliance periods.

5.5 Monitoring & Incident Response

• Continuous security monitoring and log analysis for suspicious activity.
• An incident response plan with a 24-hour notification requirement if a breach occurs.
• Regular security review and vulnerability assessment.

5.6 Communication Security

• End-to-end encrypted communications. ProtonMail end-to-end encryption is used for sensitive email, so only the intended recipient can decrypt and read a message even if it is intercepted.
• Breach detection. Threat intelligence services alert us to potential breaches involving credentials across known breach databases.
• Credential monitoring. Authentication systems are monitored for suspicious activity and compromise attempts.

5.7 Confidentiality & NDA

• All client information and project details are treated as confidential.
• Your information is never disclosed to third parties without written consent, except where legally required.
• A formal mutual NDA is available on request, and is standard for high-security projects.
• Trade secrets and proprietary methodologies are protected.

5.8 Compliance

Kappataf operates in accordance with the GDPR, and applies the practices set out in the OWASP Top Ten for web application security.

While Kappataf maintains the measures above, you are responsible for:

• Maintaining the confidentiality of your credentials and passwords.
• Notifying us immediately of any unauthorized access or security breach.
• Using strong, unique passwords and changing them regularly.
• Not sharing your login credentials with third parties.
• Ensuring your devices have up-to-date security software.
• Not transmitting sensitive information over unsecured networks.

The Site and all Site Content, including services, are provided on an "as is" and "as available" basis without warranties of any kind, either express or implied. To the fullest extent permitted by law, Kappataf disclaims all warranties, express or implied, including but not limited to merchantability, fitness for a particular purpose, non-infringement, title, accuracy or completeness of content, and uninterrupted or error-free service.

To the fullest extent permitted by law, in no event shall Kappataf, its owners, operators, employees or agents be liable for any indirect, incidental, special, consequential or punitive damages, including but not limited to damages for loss of profits, goodwill, use, data or other intangible losses, even if Kappataf has been advised of the possibility of such damages.

Our total liability to you for any claim arising from or relating to the Site or these Terms shall not exceed the amount you paid to Kappataf in the twelve months preceding the claim.

You agree to indemnify, defend and hold harmless Kappataf and its owners, operators, employees and agents from any claims, damages, losses, liabilities and expenses, including reasonable attorney fees, arising from or relating to your violation of these Terms, your violation of any applicable laws or regulations, your use of the Site or services, your infringement of third-party intellectual property rights, or content you provide or generate.

Payment terms are specified in individual project agreements. A 50% deposit is typically required to begin work, with the balance due on completion. Refunds are provided only if Kappataf fails to deliver the agreed Work Product. Custom projects are non-refundable once work has commenced, unless the Work Product is unacceptable due to Kappataf's negligence.

Kappataf reserves the right to terminate or suspend your access to the Site or services at any time, with or without notice, including for:

• Violation of these Terms.
• Fraudulent, abusive or unlawful activity, or activity that we reasonably believe to be so.
• Non-payment of fees due under a project agreement.
• Conduct that harms, or is likely to harm, other users, third parties or the Company.
• A requirement imposed by law, regulation or a competent authority.

Termination does not relieve you of amounts already due, and does not affect any licence granted for a Work Product already paid for in full. Sections 4, 7, 8 and 9 survive termination.

These Terms are governed by the laws of the Hellenic Republic, without regard to conflict of law provisions. Any dispute arising from or relating to these Terms or the services shall be subject to the exclusive jurisdiction of the competent courts of Greece. Nothing in this clause removes any protection available to you as a consumer under the mandatory law of your country of residence.

These Terms may be updated to reflect changes in practice, technology or legal requirements. The revised version is published on this page with a new update date. Continued use of the Site after a change constitutes acceptance of the revised Terms. Changes do not apply retroactively to a project agreement already signed.

If any provision of these Terms is found to be unenforceable, that provision is severed and the remainder continues in full force. These Terms, together with the Privacy Policy and any signed project agreement, constitute the entire agreement between you and Kappataf regarding the Site and the services, and supersede any prior understanding on the same subject. Where a signed project agreement conflicts with these Terms, the project agreement prevails for that project.

Kappataf, operated by Konstantinos Tsaldaris, Greece.
