These Terms govern your access to and use of the Theostack platform at app.theostack.com, our marketing site at theostack.com, and all related services (collectively, the “Service”).

By creating an account or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. Eligibility

You must be at least 13 years old to use the Service. If you are between 13 and 18 years old, you must have the consent of a parent or legal guardian who agrees to these Terms on your behalf.

By using the Service, you represent that you meet these requirements and that the information you provide is accurate.

2. Account Registration

To access the Service, you must create an account using a valid email address. We use passwordless authentication (magic link). You are responsible for maintaining access to the email account associated with your Theostack account.

You are responsible for all activity that occurs under your account. If you believe your account has been compromised, contact us immediately at hello@theostack.com.

You may not create more than one individual account. You may not share your account credentials with others. You may not transfer your account to another person without our written consent.

5. AI-Generated Content

5.1 Nature of AI Responses

Theostack uses artificial intelligence to generate responses to your queries. AI-generated content is produced by third-party language models drawing on our curated theological library and, where applicable, your uploaded documents.

5.2 No Substitute for Pastoral Judgment

AI-generated responses are provided as research aids and starting points, not as authoritative theological conclusions. You are solely responsible for evaluating, verifying, and applying any information provided by the Service. Theostack does not replace pastoral training, denominational accountability, or the leading of the Holy Spirit.

5.3 Citation and Attribution

Theostack is designed to cite sources from the curated library when generating responses. While we strive for accurate attribution, AI systems can produce errors, including incorrect citations or misattributed content. You should verify citations against original sources before relying on them in published or public-facing work.

5.4 No Guarantees of Accuracy

We do not warrant that AI-generated content is accurate, complete, theologically sound, or free of error. The Service is a tool to assist your research, not a guarantee of correctness.

6. Intellectual Property

6.1 Our Intellectual Property

The Theostack platform, including its design, code, user interface, branding, and curated theological library organization, is the intellectual property of Lordhill Digital LLC. The curated library contains works that may be in the public domain, licensed for inclusion, or presented as Theostack-generated companion research documents. The selection, arrangement, and presentation of the library are proprietary.

You may not copy, modify, distribute, or create derivative works based on the Service or its components, except as expressly permitted by these Terms.

6.2 Your Content

You retain ownership of all content you create, upload, or input into the Service, including your conversations, uploaded documents, and Project contents (“Your Content”).

By using the Service, you grant us a limited, non-exclusive license to process, store, and transmit Your Content solely for the purpose of providing and improving the Service. This includes sending Your Content to third-party AI providers for processing and indexing Your Content to enable search functionality.

We will not use Your Content for advertising, sell it to third parties, or use it to train AI models.

6.3 Feedback

If you provide us with feedback, suggestions, or ideas about the Service, you grant us a non-exclusive, royalty-free, worldwide license to use that feedback for any purpose, including improving the Service, without obligation to you.

7. Organization-Specific Terms

If you create or join an organization (Church plan), the following additional terms apply:

7.1 Organization Administration

Each organization has a single administrator. The administrator is responsible for managing membership, configuring the organization's theological profile, and managing billing. Administration is transferable to another organization member.

7.2 No Dual Subscriptions

A user may be on an individual plan or a member of an organization, but not both simultaneously. If an individual subscriber upgrades to create an organization, their individual subscription is canceled with proration.

7.3 Member Removal

When the administrator removes a member from the organization, that member's personal content associated with the organization (personal Projects, conversations, uploaded files) is permanently deleted. Contributions the member made to shared organization Projects are retained. The removed member may create a new individual account after removal.

7.4 Organization Data

The administrator can view aggregate usage statistics for members (message count, last active date, assistants used, storage consumed) but cannot view personal conversation content, personal Project contents, or individual chat history of other members.

8. Privacy

Your use of the Service is subject to our Privacy Policy, which is incorporated into these Terms by reference. Please review the Privacy Policy for details on how we collect, use, and protect your information.

9. Third-Party Services

The Service relies on third-party providers for AI processing, payment (Stripe), cloud infrastructure, search, and email delivery. Your use of the Service may be subject to the terms and policies of these providers. We are not responsible for the practices, availability, or performance of third-party services, though we select providers with care and monitor their data handling commitments.

10. Availability and Modifications

10.1 Service Availability

We strive to keep the Service available and reliable, but we do not guarantee uninterrupted access. The Service may be temporarily unavailable due to maintenance, updates, or circumstances beyond our control.

10.2 Modifications to the Service

We reserve the right to modify, update, or discontinue any feature of the Service at any time.

We will not reduce the features of your plan mid-billing-cycle without offering a prorated refund or equivalent accommodation.

10.3 Modifications to These Terms

We may update these Terms from time to time. If we make material changes, we will notify you by email or by posting a notice on the Service at least 14 days before the changes take effect. Your continued use of the Service after the effective date of any changes constitutes your acceptance of the updated Terms. If you do not agree to the updated Terms, you must stop using the Service and may cancel your subscription.
