AdFontes.AI (“AdFontes,” “we,” “us”) is operated by AdFontes.AI, Inc. AdFontes lets you converse with AI representations of historical Christian thinkers, convene multi-author panels, and study Scripture with an AI guide. This policy explains what we collect, how we use it, and the choices you have.

1. Information we collect

a. Account information. When you create an account we collect your email address, username, and authentication credentials, plus your subscription tier and status.

b. Conversation content. We store the content of your interactions with the app — the prompts and questions you type, and the AI-generated responses you receive — across Chat, Panel, and Study modes, along with which author/voice and passages were involved. This is core to the service: it’s how your conversations persist so you can return to them.

c. Usage and device data. We collect behavioral analytics about how the app is used — for example, which features you use, when you start and return to conversations, session frequency and approximate time spent, and coarse measures (such as message-length ranges). This behavioral analytics does not include the text of your messages — it is limited to identifiers, counts, and categories. How your conversation content itself may be used and reviewed is described separately in Sections 3 and 6.

d. Payment information. If you subscribe to a paid plan, payment is processed by Stripe. We do not store your full payment-card details; we receive only the limited billing information needed to manage your subscription.

e. Optional email list. If you opt in at signup or in your account settings, we add your email address to our mailing list, The Footnote, which is delivered through Beehiiv; it carries reflections, tips, and product news from AdFontes, it is never required to use the service, and every message includes an unsubscribe link you can use at any time.

2. How we use your information

We use your information to:

• Provide the service — run your conversations, persist your history, and deliver Chat, Panel, and Study features.
• Operate and secure the platform — authentication, fraud and abuse prevention, debugging.
• Understand and improve the product — analyze usage and tune our prompts, retrieval, and features to see what’s working and what to build next, subject to the tier-based choices in Section 3.
• We do not train AI models on your conversations. Improving the product does not include using your conversation content to train AI models.

3. Your data, your tier, and your choices

We treat data use differently depending on your plan:

• Free-tier accounts. By using the free tier, you agree that your data — including conversation content and usage — may be used to operate and improve the product: quality review, analytics, and tuning our prompts, retrieval, and features. (We do not train AI models on your conversations — see Section 2.) Use of the free tier is conditioned on this.
• Paid accounts — opt-out. Paid subscribers can opt out of having their data used for product improvement, through a setting in your account. Opting out does not change the core functionality of your subscription; we will still process your data as needed to provide the service to you — for example, to store and display your conversation history.

Regardless of tier, you can request access to or deletion of your account data — see Section 7.

4. AI providers and how prompts are processed

To generate responses, your prompts and relevant retrieved text are sent to third-party AI model providers (currently OpenAI and Anthropic) and processed through our retrieval system (Pinecone). These providers process the content to return a response. We select providers that offer business/enterprise data terms intended to keep submitted content from being used to train their foundation models, but their handling of data is governed by their own terms and privacy policies.

5. Service providers (subprocessors)

We share data with vendors who help us run AdFontes, only as needed to provide the service:

We do not sell your personal information.

6. Administrative access

Authorized staff may access and review conversation content — including individual users’ prompts and responses — to operate, secure, debug, and improve the Service. Using conversation content for product improvement and quality review follows the tier-based terms in Section 3: it applies to free-tier accounts, and paid subscribers can opt out in account settings. Access needed to run, secure, and troubleshoot the Service continues regardless of that choice, and is restricted to authorized personnel.

7. Your rights and choices

We extend the same core data rights to all users, regardless of where you live. You may access, correct, export, or delete your personal data, and object to or restrict certain processing. To exercise any of these, or to delete your account, contact us at privacy@adfontes.ai. Paid subscribers can manage the product-improvement opt-out from account settings (Section 3). Your The Footnotepreference can be changed at any time in your account settings or through the unsubscribe link in any message we send. Where local law (such as GDPR or CCPA/CPRA) grants additional rights, those also apply.

8. Data retention

We retain your account information and conversation content for as long as your account is active. When you delete your account or specific content:

• Active data is deleted or de-identified within 30 days. In practice, deleting your account removes your conversations from our active systems immediately.
• We do not maintain a separate long-term archive of deleted conversations, and deleted content is not used to restore an account once it has been removed.
• Billing and tax records are retained as long as required by law (which may be several years), even after your account is deleted.

9. Security

We use technical and organizational measures to protect your data, including access controls and encryption in transit. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

10. Children

AdFontes is not directed to children under 18, and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact privacy@adfontes.ai.

11. Changes to this policy

We may update this policy from time to time. If we make material changes, we will notify you (for example, by email or an in-app notice) and update the effective date above.
