Effective date: 28 August 2026

By installing, copying, or using the Software you agree to this Agreement, together with the Epoch Studio Privacy Policy and AI Processing Addendum, which are provided with the Software and available from us on request. If you do not agree, do not install or use the Software. If you accept on behalf of an organization, you represent that you are authorized to bind it.

If you obtained the Software through Steam, your purchase, refund, and account relationship with Valve is governed by the Steam Subscriber Agreement. Nothing here limits any right you have under that agreement or under applicable consumer law.

Subject to this Agreement, we grant you a personal, worldwide, non-exclusive, non-transferable, revocable license to install and use the Software on devices you own or control. Commercial and professional authoring use is expressly permitted — you may write, produce, publish, and sell the works you create with the Software. This is a license, not a sale of the Software; we and our suppliers retain all rights not expressly granted.

Builds distributed as a playtest, beta, or other pre-release are provided for evaluation only. They are incomplete, may contain defects, and may be changed, disabled, or withdrawn at any time. Access to a playtest may be ended at any time. Keep your own backups of anything you care about, and do not rely on a pre-release build as the only copy of your work.

4.1 You own your work. As between you and us, you retain all right, title, and interest in the manuscripts, notes, characters, worlds, images you supply, and the outputs you create with the Software ("Your Content"). This Agreement gives us no ownership of and no copyright in Your Content.

4.2 Limited license to operate the features. You grant us a limited, revocable license to process Your Content locally on your device solely to provide the Software's features — writing, analysis, world-modeling, publishing. This does not extend to training models, or to any purpose beyond running the features you invoke.

4.3 Cloud processing is your choice. The Software is local-first. Your Content is sent to a third party only when you configure an external provider, such as a cloud language-model or image API key, and the privacy setting that blocks cloud manuscript routing is off.

4.4 Export. You can export your projects at any time, in the Software's supported formats. Export remains available regardless of any subscription or license state.

We will not use Your Content to train, fine-tune, or evaluate any machine-learning model without your explicit, separate, opt-in consent. Local analysis, and any cloud inference you choose to enable, are used only to produce the features you invoke — never to improve models generally.

6.1 The Software uses AI models, local and — at your option — third-party cloud, to generate suggestions, analysis, chat, and images. AI output can be inaccurate, inconsistent, biased, or unsuitable. You are responsible for reviewing, editing, and deciding whether to use any output.

6.2 We make no representation that AI-assisted output is original, non-infringing, or eligible for copyright or other registration. The law for AI-assisted works is unsettled and varies by jurisdiction. You are solely responsible for clearing rights in, and for the publication of, your work.

6.3 The Software does not assert, register, or guarantee any legal protection for Your Content.

7.1 The Software may include, or offer to download, open-source AI models. Your use of those models is also governed by their licenses, which are reproduced in the Third-Party Notices provided with the Software and in any in-app model terms.

7.2 Models we bundle or auto-download are limited to those whose licenses permit redistribution. Models under licenses that do not permit bundling are offered only as an optional, user-initiated download from the provider, and are not redistributed by us.

If you configure third-party AI or research services, your use of those services is governed by their terms and privacy policies, and you are responsible for any keys, fees, and content you send to them. We do not control, and are not responsible for, third-party services or their data handling. The Privacy Policy lists every service the Software can reach.

You agree not to use the Software to:

• create or distribute content that is illegal where you are;
  
• produce non-consensual sexual or intimate imagery, or any sexual content involving minors;
  
• create deceptive depictions of real people without their consent;
  
• infringe the intellectual property of others;
  
• circumvent technical protection measures, or import material you are not authorized to use;
  
• violate the terms of any third-party service you connect.

The Software may check for and install updates. Updates are governed by this Agreement unless they are accompanied by new terms. The Privacy Policy describes what an update check transmits.

The Software stores your work locally on your device by default. You are responsible for your own backups. We are not liable for loss or corruption of locally stored data.

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTY REGARDING AI OUTPUT, ACCURACY, OR AVAILABILITY.

Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you. Nothing here excludes liability that cannot lawfully be excluded.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, EPOCH WORKS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, OR FOR LOST PROFITS, DATA, OR GOODWILL.

OUR TOTAL LIABILITY ARISING OUT OF OR RELATING TO THE SOFTWARE IS LIMITED TO THE GREATER OF (a) THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, AND (b) FIFTY UNITED STATES DOLLARS (US $50).

Some jurisdictions do not allow the limitation of certain damages, so parts of this section may not apply to you. Nothing here limits liability for fraud, or for death or personal injury caused by negligence, where that limitation is not permitted.

This Agreement applies while you use the Software, and terminates automatically if you breach it. On termination you must stop using the Software; you keep your locally stored Content and your right to export it. Sections 4, 5, 6, 11, 12, 13, 15, and 16 survive termination.

You represent that you are not located in, and will not use the Software in, any country, or as any party, subject to applicable export-control or sanctions restrictions.

This Agreement is governed by the laws of the Commonwealth of Pennsylvania, USA, without regard to its conflict-of-laws rules. The state and federal courts located in Pennsylvania have exclusive jurisdiction over any dispute arising out of or relating to this Agreement, and you and we consent to their jurisdiction and venue.

If you are a consumer resident in a jurisdiction whose law entitles you to bring proceedings locally, or to the protection of mandatory local consumer law, nothing in this section removes that right.

We may update this Agreement. Material changes will be presented for acceptance on next launch, or otherwise communicated. Continued use after changes take effect constitutes acceptance.

This Agreement, the Privacy Policy, and the AI Processing Addendum are the entire agreement between you and us regarding the Software, and supersede prior understandings. If any provision is unenforceable, the rest remains in effect.
