Terms of Service
Last updated January 8, 2026
Welcome, and thank you for your interest in Underflow, Inc. ("Underflow," "we," or "us"). These Terms of Service ("Terms") govern your access to and use of Underflow's software, platform, and related services, including the website useunderflow.com (collectively, the "Service"). By using the Service, you agree to these Terms.
Please also read our Privacy Policy, which explains how we collect, use, disclose, and process personal data.
1. Access and use
1.1 Provision of Access
Underflow is submission management software for insurance teams. The Service connects to your email inbox, reads submission emails and attachments, extracts data from insurance documents, identifies what's missing, and handles follow-ups. Subject to your compliance with these Terms, Underflow grants you a limited, non-exclusive, non-transferable right to access and use the Service.
1.2 Service Modes
The Service may be used in different modes:
- Copilot: Underflow extracts data, flags gaps, and drafts follow-up emails for your review. You review and send.
- Autopilot: Underflow extracts data, flags gaps, drafts, and sends follow-up emails automatically without manual review. You are responsible for any emails sent in Autopilot mode.
1.3 Model Training
Underflow will not use your Content to train, or allow any third party to train, any AI models, unless you have explicitly agreed to such use.
2. Email integration
2.1 Email Access
To use the Service, you must connect your email inbox (Microsoft Outlook or Google Gmail). By connecting your inbox, you grant Underflow permission to:
- Read incoming emails and attachments
- Access email metadata (subject, sender, recipient, timestamps)
- Create draft emails in your inbox
- Send emails on your behalf (if Autopilot is enabled)
- Move emails between folders
- Create and manage folders
2.2 Your Responsibility
You represent and warrant that you have the authority to grant Underflow access to the email inbox you connect, and that your use of the Service complies with your organization's policies and any applicable laws.
2.3 Autopilot Mode
If you enable Autopilot mode, Underflow will automatically send follow-up emails without your manual review. You acknowledge that you are solely responsible for any emails sent automatically, including their content, timing, and recipients. You should review and configure Autopilot settings carefully before enabling this feature.
3. Your content
3.1 Inputs and Outputs
You may provide inputs to the Service ("Inputs"), including emails, attachments, and documents. The Service generates outputs based on your Inputs ("Outputs"), including extracted data, gap lists, draft emails, and submission records. Inputs and Outputs are collectively "Content."
3.2 Ownership
As between you and Underflow, you retain ownership of your Inputs. Subject to your compliance with these Terms, Underflow assigns to you all right, title, and interest in Outputs generated specifically for you.
3.3 License to Underflow
By submitting Inputs to the Service, you grant Underflow a limited license to use, process, and store your Content solely to provide the Service to you, comply with applicable law, enforce our terms and policies, and keep the Service safe.
3.4 Your Representations
You represent and warrant that you have all rights, licenses, and permissions necessary for Underflow to process your Inputs under these Terms, including any insurance documents, personally identifiable information, or third-party content contained therein.
4. AI limitations
You acknowledge that Outputs are generated by artificial intelligence and machine learning technology. AI has inherent limitations, including:
- Outputs may contain errors, inaccuracies, or misleading information
- Data extraction from documents may be incomplete or incorrect
- Gap identification may miss items or flag false positives
- Draft emails may require editing before sending
- The Service may not understand all document formats or handwriting
You are responsible for reviewing and verifying all Outputs before relying on them or sending any communications. Underflow is not liable for any errors in Outputs or any decisions made based on Outputs.
