Terms of Service
Last updated: May 2026
Overview
These Terms of Service (“Terms”) govern your access to and use of the EPIC Writing App website, storefront, account system, purchase process, and related services operated by Dark Matter Labs (“Company,” “we,” “us,” or “our”).
The EPIC Writing App desktop software itself is also governed by our separate End User License Agreement (EULA). If a provision in the EULA conflicts with these Terms regarding the software itself, the EULA controls for the software.
By accessing the EPIC Writing App website, purchasing our software, creating an account, downloading the application, or using the services in any way, you agree to be bound by these Terms. In addition to these Terms, you should also review our EULA, Privacy Policy, and Cookie Policy, which are incorporated by reference.
Section 1
Eligibility
You must have the legal capacity to enter into a binding agreement to use our services. Our products are sold globally and may be purchased by users of any age, but minors may only use the application with adult supervision and parental or guardian permission, especially for AI text and image generation or other content-creation features. If you are using the services on behalf of another person or entity, you represent that you have authority to bind them to these Terms.
Section 2
Account Registration
Some features require an account. We use third-party authentication services, including Clerk, to manage sign-in and account verification. You are responsible for maintaining the confidentiality of your account access and for all activity under your account. You must provide accurate information and keep it updated.
Section 3
License Purchase and Activation
Our desktop software is sold as a one-time purchase for the stated price at the time of sale, currently $149 USD unless otherwise stated. Purchase of the software grants you a license to use the app subject to these Terms and the EULA.
Activation limits, device limits, and how you may install and use the software are governed by the EULA.
Section 4
Updates and Versions
Minor updates, patches, and bug fixes may be included at no additional charge. Major new versions or major upgrades may be offered separately for an additional fee. We may also change, modify, or discontinue features, provided we act in accordance with applicable law and any express commitments made at the time of purchase.
Section 5
Refunds and Chargebacks
All sales are final and non-refundable to the maximum extent permitted by law. Because the product is a downloadable software license and digital content may be delivered immediately, refunds are generally not offered after purchase, except where required by applicable law or where we choose to issue a refund at our discretion. Nothing in these Terms limits any non-waivable consumer rights that apply in your jurisdiction. See our full Refund Policy for details.
Section 6
Software Restrictions
Software-specific restrictions, including reverse engineering, copying, reselling, distribution, and activation limits, are set out in the EULA. By using the software, you agree to comply with those restrictions.
Section 7
Acceptable Use
You agree not to misuse the website or application. This includes trying to interfere with the platform, overload systems, abuse rate limits, attempt unauthorized access, scrape data improperly, or use the software for illegal, harmful, deceptive, or infringing activity. We may suspend or terminate access if we reasonably believe you have violated these Terms or created risk to the service, users, or third parties.
Section 8
Offline and Local Storage
Our desktop app is designed to work offline and saves user-generated content on the user's own device. You are responsible for backing up your data. If you uninstall the application or lose your device, we may not be able to recover your local data. Details about local storage and offline use are in the EULA.
Section 9
User API Keys and Third-Party AI Services
Some features allow you to add your own API keys for third-party AI providers such as Anthropic, OpenAI, OpenRouter, Replicate, or similar services. These keys are stored on your device and not accessible to us. If you choose to use those services, you are responsible for complying with their terms, usage limits, and policies. We are not responsible for third-party services, their outputs, or any charges they may impose.
Section 10
AI-Generated Content
The app may generate text, images, maps, notes, or other outputs using local models or third-party providers. AI-generated content may be inaccurate, incomplete, offensive, or inappropriate, and you should review it before relying on it. You are solely responsible for how you use, publish, export, or distribute content generated through the app.
Section 11
Intellectual Property
The website, application, software code, design, branding, logos, text, and related materials are owned by or licensed to Dark Matter Labs and are protected by intellectual property laws. Except for the license expressly granted to you, no rights are transferred to you. All rights not expressly granted are reserved.
Section 12
User Content
You own everything you create. You retain ownership of content you create or store on your device, subject to any rights needed for you to use the software and any rights you grant to third-party providers when you choose to send content to them. You represent that you have the rights necessary to use any content you input into the app and that your content does not infringe others' rights or violate law.
Section 13
No Warranty
The website, application, licenses, downloads, and all related services are provided on an “as is” and “as available” basis. To the maximum extent permitted by law, we disclaim all warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not guarantee uninterrupted service, error-free operation, or that the app will meet every user's needs.
Section 14
Limitation of Liability
To the maximum extent permitted by law, Dark Matter Labs will not be liable for indirect, incidental, consequential, special, punitive, or exemplary damages, or for loss of profits, data, goodwill, or business opportunities arising from or related to your use of the website or app. Our total liability for any claim will be limited to the amount you paid for the product giving rise to the claim, or the minimum amount permitted by law, whichever is greater.
Section 15
Indemnification
You agree to indemnify, defend, and hold harmless Dark Matter Labs and its affiliates, officers, employees, contractors, and agents from claims, liabilities, damages, losses, and expenses arising from your use of the services, your violation of these Terms, or your infringement of any third-party rights.
Section 16
Termination
We may suspend or terminate your access to the website, app, license, or account if you violate these Terms, if we are required to do so by law, or if we reasonably believe your use creates risk, fraud, abuse, or harm. Upon termination, your license may end and you must stop using the software. Sections that by their nature should survive termination will survive, including payment obligations, intellectual property, disclaimers, limitations of liability, and dispute provisions.
Section 17
Changes to the Service and Terms
We may update these Terms from time to time. The updated version will be posted with a revised effective date. Continued use of the website or app after the updated Terms become effective means you accept them to the extent permitted by law.
Section 18
Governing Law and Venue
Governing Law. These Terms, the EULA, the Privacy Policy, and any dispute or claim arising out of or relating to them will be governed by and construed in accordance with the laws of the State of Texas, without regard to its conflict of law principles, except where mandatory consumer protection laws require otherwise.
Venue. Except where prohibited by applicable law, any legal action or proceeding must be brought exclusively in the state or federal courts located in Texas, and you consent to the personal jurisdiction of those courts.
