Last updated: May 25, 2026
Beta Cell Foundation ("BCF," "we," "us," or "our") is a 501(c)(3) nonprofit organization (EIN 84-4054715). By accessing betacellfoundation.org, learn.betacellfoundation.org, map.betacellfoundation.org, and using our programs, tools, and services, you agree to these terms.

Educational Purpose
These sites, their simulators, educational programs, courses, and community resources are provided by Beta Cell Foundation as free educational resources. They are designed to help people with diabetes build intuition and skills for self-management. They are not medical devices, clinical tools, or substitutes for professional medical advice.
Not Medical Advice
Nothing on these sites constitutes medical advice. The content — including all simulations, educational materials, courses, workbooks, interactive tools, and community program information — is for informational and educational purposes only. Always consult your physician or healthcare provider before making changes to your diabetes management.
Education Hub Accounts
The Education Hub (learn.betacellfoundation.org) allows you to create an optional account to track course progress. By creating an account, you agree that we may store your email address and course progress data as described in our Privacy Policy. You may delete your account and all associated data at any time from the "My Progress" page.
Member Map Accounts
The Type One Run Member Map (map.betacellfoundation.org) allows you to create an optional account to add your approximate location (city, state/region, country) to a global community map. By creating an account, you agree that we may store your email address and the city/state/country you provide, as described in our Privacy Policy. The public map shows aggregated counts per city only; individual emails are visible only to BCF administrators, who use them to introduce nearby members for community building. You may delete your account, your pin, and all associated data at any time from the "Delete my account" button on the map.
Simulator Disclaimer
The simulators on these sites are visual learning tools — not diagnostic tools, dosing calculators, or clinical decision support systems. They show simplified models based on published pharmacokinetic and physiological research. They do not capture the full complexity of a living body — illness, stress, hormones, individual variation, medication interactions, and many other real-world factors are not modeled. Do not use these tools to guide specific insulin doses, meal decisions, or exercise strategies without first discussing them with a qualified healthcare provider.
Exercise Disclaimer
Community programs including Type One Run and T1Ds in the Wild involve physical activity. Participation is at your own risk. Consult your healthcare provider before beginning any exercise program. Blood sugar responses to exercise vary significantly from person to person, and the information provided through our programs is educational, not prescriptive.
Acceptable Use
You may use these sites for personal, educational, and non-commercial purposes. You may share links freely. You may not copy, reproduce, or redistribute the content, code, or simulations without written permission from Beta Cell Foundation.
Account Termination
We reserve the right to suspend or delete accounts on the Education Hub or Member Map that violate these terms, are used for spam or abuse, or compromise the security or integrity of our services. If your account is terminated by us, all associated data will be permanently deleted.
Intellectual Property
All content on these sites — including text, simulations, charts, design, educational programs, courses, and code — is the property of Beta Cell Foundation unless otherwise noted. The simulation models are based on published research, but the implementations and educational content are original works.
Third-Party Services
Our websites use third-party services including Supabase (authentication and data storage for the Education Hub and Member Map), Cloudflare Turnstile (bot protection for the Education Hub and Member Map), OpenStreetMap, CARTO, and Nominatim (map tiles and geocoding for the Member Map), Zeffy (donations and newsletters), Apple Podcasts (podcast distribution), Facebook (community groups), and SquadLocker (merchandise). We are not responsible for the content, practices, or policies of these external services. Your use of those services is governed by their respective terms.
Donations
Donations are processed through Zeffy, a third-party platform. All donations to Beta Cell Foundation are tax-deductible to the extent allowed by law.
No Warranty
These sites are provided "as is" without warranties of any kind, express or implied. Beta Cell Foundation does not guarantee that the sites will be available, error-free, or that the content is complete or current at all times.
Limitation of Liability
Beta Cell Foundation is not liable for any damages — direct, indirect, incidental, or consequential — arising from your use of these sites or reliance on their content. This includes any decisions made, actions taken, or health outcomes that result from use of these sites, their simulators, educational programs, courses, or community events. Your use of these sites is at your own risk, and your health decisions are between you and your healthcare providers.
Changes to These Terms
We may update these terms from time to time. The current version will always be available on this page. Continued use of the sites after changes constitutes acceptance of the updated terms.

Except as expressly permitted here, you may not copy, reproduce, modify, adapt, distribute, sell, rent, sublicense, publicly display, reverse-engineer, decompile, or create derivative works from the App or any part of it. All trademarks and branding of the Beta Cell Foundation remain ours. We reserve all rights not expressly granted to you.

The App can connect to services you control — Health Connect, Apple Health, and (optionally) Abbott's LibreLinkUp. Your use of those services is governed by their own terms and privacy policies.

The App is provided "as is" and "as available," without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the App will be error-free, uninterrupted, or that any information or model it displays is accurate or complete.

To the fullest extent permitted by law, the Beta Cell Foundation and its contributors shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any health-related outcomes, arising from your use of or inability to use the App. Your use of the App is at your own risk.
10. Indemnification
You agree to hold harmless the Beta Cell Foundation and its contributors from claims arising out of your misuse of the App or violation of these Terms.
