1. Acceptance of Terms

By accessing or using Cosindra (“the Service”), including the desktop application, cloud API, web platform, local MCP server, and Unreal Engine plugin (collectively, “the Software”), you agree to be bound by these Terms of Service. If you do not agree to these terms, you must not use the Service.

2. Description of Service

Cosindra is an AI-powered development platform for Unreal Engine. The Service consists of:

  • Desktop Application — Electron-based client for AI-assisted game development
  • Cloud API — Backend services for authentication, AI processing, and data management
  • Local MCP Server — On-device server that facilitates communication between AI models and Unreal Engine
  • Unreal Engine Plugin — C++ plugin that integrates with the UE5 Editor to execute AI-directed operations
  • Web Platform — Web-based interface for account management, product features, and documentation

3. Account Registration

You must provide accurate and complete information when creating an account. You are solely responsible for maintaining the confidentiality of your account credentials. You must be at least 16 years old to use the Service. You may not create multiple accounts to circumvent plan limits or abuse free tier allocations.

4. Subscription Plans & Billing

The Service offers multiple subscription tiers (Starter, Pro, Elite, Studio). Each plan includes specific usage limits for AI messages, model tiers, Blueprint generations, WorldWeaver generations, and project slots. Usage beyond plan limits may be restricted or subject to overage charges if enabled.

  • Subscriptions renew automatically at the end of each billing period unless cancelled
  • You may cancel your subscription at any time from your account settings. A confirmation email will be sent upon cancellation
  • Cancellation takes effect at the end of the current billing period
  • We reserve the right to modify pricing with 30 days advance notice via email

4.1 Refund & Withdrawal Policy

If you are a consumer in the European Union, you have the right to withdraw from your purchase within 14 days without giving a reason, in accordance with the Consumer Rights Directive (2011/83/EU). By beginning to use the Service immediately after purchase, you expressly consent to waive your right of withdrawal. If you have not used any paid features of the Service, you may request a full refund within 14 days of purchase by contacting [email protected].

For all other jurisdictions, no refunds are provided for partial billing periods unless required by applicable local law.

5. Acceptable Use

You agree not to:

  • Use the Service for any unlawful, fraudulent, or harmful purpose
  • Attempt to circumvent, disable, or interfere with rate limits, usage quotas, or plan restrictions
  • Create multiple accounts to exploit free tier limits or promotional offers
  • Share, sell, or redistribute your account credentials or subscription access
  • Use automated tools to create accounts, send messages, or bypass security measures
  • Interfere with or disrupt the Service infrastructure, servers, or networks
  • Attempt to gain unauthorized access to any part of the Service, other users' accounts, or our systems
  • Scrape, harvest, or extract data from the Service for any unauthorized purpose

6. Intellectual Property — Your Content

You retain all rights to the content you create using Cosindra, including but not limited to game assets, blueprints, source code, materials, levels, and any other creative output generated through or with the assistance of the Service. Cosindra does not claim ownership of your creations.

7. Intellectual Property — Our Software

The Service, including all software components, source code, object code, algorithms, tools, prompts, designs, documentation, and trade secrets, is the exclusive property of Cosindra and is protected by intellectual property laws. You are granted a limited, non-exclusive, non-transferable, revocable license to use the Software solely for your own game development purposes in accordance with your subscription plan.

You expressly agree not to:

  • Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, algorithms, or internal structure of any part of the Software, except to the extent that such activity is expressly permitted by applicable law notwithstanding this limitation
  • Modify, adapt, translate, or create derivative works based on the Software
  • Copy, reproduce, distribute, sublicense, lease, lend, or sell any part of the Software to any third party
  • Remove, alter, or obscure any copyright notices, trademarks, or other proprietary notices in the Software
  • Extract, copy, or reuse any system prompts, agent instructions, tool definitions, or AI configuration data embedded in or transmitted by the Software
  • Copy, reproduce, or directly replicate the Software's proprietary algorithms, tool implementations, or system architecture for the purpose of creating a competing product or service
  • Redistribute the Unreal Engine plugin, local MCP server binary, or desktop application to unauthorized users

8. Unreal Engine Plugin

The Cosindra Unreal Engine plugin is provided under a limited license for use exclusively with the Cosindra Service. The plugin source code, where provided for compilation purposes, remains the intellectual property of Cosindra. You may not:

  • Extract, copy, or use the plugin code outside of the Cosindra ecosystem
  • Redistribute the plugin or any part of it to third parties
  • Use the plugin code as a basis for developing competing tools or services
  • Modify the plugin in ways that circumvent licensing, authentication, or usage tracking

The plugin is designed to work exclusively with the Cosindra local MCP server and cloud API. Any attempt to use it independently or with unauthorized services is a violation of these terms.

9. API Keys (BYOK)

When using your own API keys (Bring Your Own Key), you are solely responsible for complying with the respective provider's terms of service (Anthropic, Google, OpenAI, DeepSeek, Mistral, etc.). Usage charges from third-party API providers are entirely your responsibility. Cosindra does not store your API keys on our servers — they are encrypted locally on your device using OS-level encryption (DPAPI on Windows, Keychain on macOS).

10. Extension Mode

The Service may offer integration with third-party AI tools through Extension Mode. When using Extension Mode:

  • You are responsible for maintaining your own subscription with the third-party AI provider
  • All API usage and costs are between you and the third-party provider
  • Cosindra acts solely as an interface layer and does not access, store, or transmit your third-party authentication tokens
  • Product features (Blueprint generation, WorldWeaver) used through Extension Mode are still subject to your Cosindra plan limits

11. Data & Privacy

Your use of the Service is also governed by our Privacy Policy. By using the Service, you consent to the collection and use of data as described therein. We collect usage analytics (message counts, tool usage, model selection) to improve the Service and enforce plan limits. We do not sell your personal data to third parties.

Your data is processed on servers located in Germany (Hetzner, Falkenstein) within the European Economic Area. For any data transfers outside the EEA, we implement appropriate safeguards in accordance with GDPR Article 46, including Standard Contractual Clauses where required.

12. Service Availability & Modifications

The Service is provided on an “as-is” and “as-available” basis. We strive for high availability but do not guarantee uninterrupted, error-free, or secure service. We reserve the right to modify, suspend, or discontinue any part of the Service at any time. During the beta period, features may change significantly.

13. Limitation of Liability

To the maximum extent permitted by applicable law, Cosindra and its founders, employees, and affiliates shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, use, or goodwill, arising out of or related to your use of the Service.

Cosindra is not liable for any damages resulting from AI-generated code, assets, blueprints, or modifications to your Unreal Engine projects. You are solely responsible for reviewing, testing, and validating all AI-generated output before integrating it into production builds.

14. Disclaimer of Warranties

THE SERVICE IS PROVIDED “AS IS” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. COSINDRA DOES NOT WARRANT THAT THE SERVICE WILL MEET YOUR REQUIREMENTS, THAT AI-GENERATED OUTPUT WILL BE ACCURATE OR SUITABLE, OR THAT THE SERVICE WILL BE AVAILABLE AT ALL TIMES.

15. Indemnification

You agree to indemnify, defend, and hold harmless Cosindra and its founders, employees, and affiliates from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to your violation of these Terms or your violation of any third-party rights. This indemnification does not apply to claims arising from Cosindra's own negligence or breach of its obligations under these Terms.

16. Beta Program

During the public beta period, certain features are available free of charge or at reduced rates. Beta features are experimental and may be modified or removed without notice. We reserve the right to modify pricing, plan limits, and feature availability when the beta period ends. Registered beta users will receive advance notice of material changes.

17. Termination

We may suspend or terminate your account for material violations of these Terms, fraudulent or abusive behavior, or if we reasonably believe your use poses a security risk. Where possible, we will provide notice and a reason for termination. Upon termination, you will have 30 days to export your data before it is permanently deleted. You may delete your account at any time from your account settings.

Sections 6, 7, 8, 13, 14, 15, and 19 survive termination.

18. Changes to Terms

We may update these Terms from time to time. Material changes will be communicated via email at least 30 days before taking effect. For material changes that affect your rights or obligations, we will request your explicit consent. If you do not agree to the updated Terms, you may cancel your subscription before the changes take effect. Non-material changes (such as clarifications or formatting updates) take effect upon posting.

19. Governing Law & Dispute Resolution

These Terms shall be governed by and construed in accordance with the laws of the Republic of Turkey. Any disputes arising from these Terms shall be resolved in the courts of Istanbul, Turkey.

If you are a consumer in the European Union, you will benefit from any mandatory provisions of the law of your country of residence. Nothing in these Terms affects your rights as a consumer under applicable local law.

If you are a consumer in the European Union, you may also use the EU Online Dispute Resolution platform at https://ec.europa.eu/consumers/odr to resolve disputes.

20. Severability

If any provision of these Terms is found to be invalid, illegal, or unenforceable by a court of competent jurisdiction, the remaining provisions shall continue in full force and effect. The invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable.

21. Force Majeure

Cosindra shall not be liable for delays or failures in performance resulting from events beyond our reasonable control, including but not limited to natural disasters, war, terrorism, pandemics, government actions, third-party service outages, or internet infrastructure failures.

22. Entire Agreement

These Terms, together with the Privacy Policy, constitute the entire agreement between you and Cosindra regarding the use of the Service and supersede all prior agreements and understandings.
