By accessing or using Plotheus ("the Service"), you agree to be bound by these Terms of Use. If you do not agree, you must not use the Service. We may update these Terms from time to time, and continued use constitutes acceptance of the updated Terms.
Plotheus is a story architecture platform that allows writers to structure their narrative worlds, define characters, places, events, and relationships, and assemble context packages for use with AI writing tools. The Service is currently in private beta.
To use Plotheus, you must:
You are responsible for all activity that occurs under your account.
You retain full ownership of all story content, characters, world-building data, and other creative works you create using Plotheus. We claim no intellectual property rights over your content.
By using the Service, you grant us a limited, worldwide, non-exclusive, royalty-free licence to host, store, reproduce, transmit, and display your content solely to the extent necessary to provide, maintain, secure, and improve the Service, and to make it available to the collaborators you designate. This licence ends when you delete your content or close your account, subject to short-term retention in backups as described in our Privacy Policy.
You are solely responsible for your content and for confirming that you have the rights to upload it. If you believe content on Plotheus infringes your copyright or other rights, please send a written notice to legal@plotheus.com describing the content, its location on the Service, and your claim. We will review the notice and, where appropriate, remove or disable access to the content in line with applicable law.
You agree not to:
Plotheus provides tools to assemble and export context for use with third-party AI services. We do not host, proxy, or control AI models. When you export context to an AI provider:
We strive to keep Plotheus available and reliable, but we do not guarantee uninterrupted access. The Service may be temporarily unavailable for maintenance, updates, or due to circumstances beyond our control. We are not liable for any loss resulting from service interruptions.
Plotheus is currently in beta. Features may change, be removed, or behave unexpectedly. While we take reasonable care of your data, you should maintain your own backups of important creative work. We appreciate your feedback during this period.
The Plotheus platform, including its design, code, branding, logos, and documentation, is our intellectual property and is protected by copyright, trademark, and other laws. You may not copy, modify, reverse-engineer, or create derivative works of the platform itself, or remove any proprietary notices. This does not affect your rights to your own content created using the platform.
The Service is provided on an "as is" and "as available" basis. To the maximum extent permitted by applicable law, we disclaim all warranties of any kind, whether express or implied, including, without limitation, warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted or error-free operation. We do not warrant that the Service will meet your requirements, that stored content will always be preserved without loss, or that defects will be corrected.
Nothing in these Terms limits or excludes any warranty, right, or remedy that cannot be limited or excluded under mandatory law (for example, statutory consumer rights under EU or Spanish consumer protection law).
To the maximum extent permitted by law, Plotheus and its operators, officers, employees, and contractors shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, goodwill, data, or creative work, arising from or related to your use of or inability to use the Service, even if we have been advised of the possibility of such damages.
Our total aggregate liability arising out of or in connection with these Terms or the Service shall not exceed the greater of (a) the total amounts paid by you to us for the Service in the twelve months preceding the event giving rise to the claim, or (b) one hundred euros (EUR 100).
Nothing in this section excludes or limits our liability for fraud, wilful misconduct, gross negligence, death, personal injury caused by our negligence, or any other liability that cannot be excluded or limited by law.
To the extent permitted by law, you agree to defend, indemnify, and hold harmless Plotheus and its operators from and against any claims, damages, liabilities, costs, and expenses (including reasonable legal fees) arising out of or related to: (a) your use of the Service in violation of these Terms; (b) content you upload or generate through the Service that infringes the rights of a third party or violates applicable law; or (c) your breach of any representation, warranty, or obligation in these Terms.
You may close your account at any time from within the application or by emailing privacy@plotheus.com. Before closing your account, you may export your data in a machine-readable format using the export tools we provide (or by contacting us if no such tool is available for a given data type).
We may suspend or terminate your access to the Service, in whole or in part, with or without notice, if: you materially breach these Terms; your use of the Service creates a legal or security risk for us or for other users; or we are required to do so by law. Upon termination, your right to use the Service ceases, and we will delete your data in accordance with our Privacy Policy. Sections that by their nature should survive termination (including Sections 9 through 12, 14, and 15) will survive.
These Terms, and any non-contractual obligations arising out of or in connection with them, are governed by the laws of the country in which the operator of Plotheus is established, without regard to its conflict of laws rules. Any dispute, controversy, or claim arising out of or relating to these Terms or the Service shall be submitted to the exclusive jurisdiction of the competent courts of that country, except where otherwise required by mandatory law.
If you are a consumer resident in the European Union, nothing in this section deprives you of the protection of the mandatory consumer laws of your country of residence, and you retain the right to bring proceedings in the courts of that country. The European Commission also provides an online dispute resolution platform available at https://ec.europa.eu/consumers/odr.
Entire agreement. These Terms, together with the Privacy Policy and the Cookie Policy, constitute the entire agreement between you and us regarding the Service and supersede any prior agreements on the same subject.
Severability. If any provision of these Terms is held to be invalid, illegal, or unenforceable by a competent court, that provision will be modified to the minimum extent necessary to make it enforceable, or struck out, and the remaining provisions will remain in full force and effect.
No waiver. Our failure to enforce any right or provision of these Terms will not be considered a waiver of that right or provision.
Assignment. You may not assign or transfer these Terms or any rights under them without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets, provided that the assignee honours your rights under them.
Force majeure. We are not liable for any failure or delay in performance caused by events beyond our reasonable control, including natural disasters, network or infrastructure outages, acts of government, or denial-of-service attacks.
