Terms of Service

Last updated: October 2, 2026  ·  Effective date: October 2, 2026
See also: Privacy Policy  ·  Consumer Health Data Privacy Policy

These Terms of Service ("Terms") are a legal agreement between you and GlucoWorks LLC ("GlucoWorks," "we," "us," or "our"), a North Carolina limited liability company. They govern your use of the SuperGlu mobile application (the "App"), our websites, and related services (together, the "Service").

PLEASE READ SECTION 18 CAREFULLY. IT REQUIRES MOST DISPUTES TO BE RESOLVED BY INDIVIDUAL ARBITRATION RATHER THAN IN COURT, WAIVES CLASS ACTIONS AND JURY TRIALS, AND EXPLAINS HOW YOU CAN OPT OUT WITHIN 30 DAYS.

By checking the box to agree and creating an account, you accept these Terms and our Privacy Policy. If you do not agree, do not use the Service.

1. SuperGlu Is Not a Medical Device and Does Not Give Medical Advice

SuperGlu is a personal logbook and information tool. It records meals, glucose readings, insulin and medication records, and related data, and shows you descriptive information about your own history.

  • SuperGlu is not a medical device. It has not been cleared or approved by the U.S. Food and Drug Administration (FDA). It does not diagnose, treat, cure, mitigate, or prevent any disease or condition.
  • SuperGlu does not calculate, recommend, or suggest insulin doses, medication doses, or changes to any treatment setting (including insulin-to-carb ratios, correction factors, or pump settings). Any comparison the App shows between your settings and your historical records describes the past only. It is not a recommended setting.
  • Nutrition estimates are estimates. They may be inaccurate, sometimes significantly. They are not verified nutritional facts.
  • Scores, labels, and patterns describe what happened in your own past data. They do not predict how your body will respond in the future.
  • SuperGlu is not a glucose monitor or alarm. Glucose data may be delayed, incomplete, or missing. Never use SuperGlu to make real-time treatment decisions, and never use it in place of your CGM’s own app, alarms, or receiver.
  • No doctor-patient relationship. Using SuperGlu does not create a doctor-patient or other healthcare-provider relationship. GlucoWorks does not employ healthcare professionals to review your data.

You are responsible for your healthcare decisions. Always use your own judgment. Confirm values with your own devices and records, and consult your physician or diabetes care team before changing your diet, medication, insulin, or treatment plan.

In an emergency, including severe low or high blood sugar or symptoms of diabetic ketoacidosis, call 911 or your local emergency number immediately. Do not rely on SuperGlu for emergency guidance.

2. Eligibility

To use the Service, you must:

  • be at least 18 years old;
  • live in the United States; and
  • be able to enter into a binding contract.

The Service is not available outside the United States. You may not use it if you are barred from doing so under U.S. law, including sanctions and export laws.

3. Your Account

  • You must provide accurate information and keep your login credentials secure.
  • You are responsible for activity under your account.
  • Tell us promptly at support@glucoworks.com if you suspect unauthorized use.
  • An account is for one person and may not be shared or transferred.

4. Description of the Service

SuperGlu lets you:

  • photograph and log meals and receive AI-generated nutrition estimates;
  • log medications, insulin, alcohol, and ketone readings;
  • connect supported data sources; and
  • view your history, outcome scores, and patterns.

Features may change over time. We may add, change, or remove features, and some may be labeled beta or experimental and may be less reliable.

5. AI-Generated Content

SuperGlu uses third-party AI models, including models provided by OpenAI and Anthropic, as described in our Privacy Policy. You acknowledge that:

  • AI-generated content, including nutrition estimates, restaurant identification, alcohol detection, medication label readings, and written summaries, may be inaccurate, incomplete, or wrong;
  • you must review and verify AI-generated content, including any medication label reading, before relying on it or saving it; and
  • you are responsible for evaluating and acting on any AI-generated content.

6. Connected Data Sources

SuperGlu can receive data from third-party services you choose to connect, including Apple Health, Dexcom (where available), FreeStyle Libre (through LibreLinkUp), and Tandem pumps (through Tandem Source / t:connect).

  • No affiliation. GlucoWorks is not affiliated with, sponsored by, or endorsed by Apple, Dexcom, Abbott, or Tandem Diabetes Care. Their names and trademarks belong to their owners and are used only to identify compatibility.
  • Unofficial connections. The FreeStyle Libre and Tandem connections use methods that those manufacturers do not provide or support. They may stop working at any time without notice, and the manufacturer may change or block them. By connecting, you confirm that you are authorized to use those accounts this way, and that you are responsible for complying with the terms that apply to your accounts with those manufacturers.
  • Credentials. If you provide account credentials for a connected service (for example, Tandem Source), you authorize us to use them solely to retrieve your data for the Service, as described in our Privacy Policy.
  • No responsibility for third-party data. We do not control and are not responsible for the accuracy, completeness, timeliness, or availability of data from third-party services. Data may be delayed or missing.
  • Your use of third-party services is governed by their terms and privacy policies.

7. Subscriptions, Free Trial, and Payment

7.1 Free features and SuperGlu Premium

Without a subscription, you can view, search, and filter your existing data and edit the tags, notes, and restaurant information on your existing entries.

A SuperGlu Premium subscription is required to:

  • create new logs (meals, events, ketone readings);
  • use AI-powered features (including nutrition estimates, re-analysis, the query box, and medication label scanning);
  • connect or import data from Dexcom, Libre, Tandem, or Apple Health; and
  • refresh or regenerate summaries.

We may change which features are free or Premium. Any change will not reduce features you have already paid for during your current billing period.

7.2 Free trial

New accounts may receive a 7-day free trial of Premium features, granted by GlucoWorks.

  • The trial does not require a payment method and does not automatically convert to a paid subscription.
  • When it ends, your account returns to free features unless you choose to subscribe.
  • We may change or end trial offers at any time, and trials are limited to one per person.

7.3 Paid subscriptions

Premium is available as a monthly or annual auto-renewing subscription at the price shown in the App and on the App Store at the time of purchase.

  • Payment is charged to your Apple ID account when you confirm your purchase.
  • Your subscription renews automatically at the end of each period, at the then-current price, unless you turn off auto-renewal at least 24 hours before the period ends. Your account will be charged for renewal within 24 hours before the end of the current period.
  • You can manage or cancel your subscription in your Apple ID settings (App Store → your profile → Subscriptions). Cancellation takes effect at the end of the current billing period.
  • Refunds are handled by Apple under its policies (reportaproblem.apple.com). We do not provide partial refunds for unused portions of a billing period, except where required by law.
  • If we raise prices, we will give advance notice as required by Apple and applicable law.
  • All payments are processed by Apple. We do not receive or store your payment card information.

8. Your Content and Data

You own your content. This includes meal photos, notes, logs, and other information you submit or connect ("Your Content").

License to us. You grant GlucoWorks a non-exclusive, worldwide, royalty-free license to host, store, copy, process, transmit, display, and create derived information from Your Content, solely to:

  • provide, maintain, secure, and improve the Service for you; and
  • create de-identified reference data as described in our Privacy Policy, which you can opt out of in Settings.

This license ends when you delete Your Content or your account. It does not end for de-identified data already created, or for backup copies that are being overwritten as described in our Privacy Policy. We will not use identifiable Your Content to train AI models without your separate, opt-in consent.

Your responsibilities for Your Content. You are responsible for Your Content. You confirm that you have the rights to submit it, and that it does not include other people’s personal information without their permission.

Feedback. If you send us suggestions or feedback about the Service, we may use them without obligation to you.

9. Acceptable Use

You agree not to:

  • use the Service for anyone other than yourself, or enter another person’s health data without their permission;
  • use the Service in any way that violates law or the rights of others;
  • reverse engineer, decompile, scrape, or attempt to extract the source code, models, prompts, or data of the Service, except as permitted by law;
  • interfere with or disrupt the Service, bypass usage limits or access controls, or access the Service through unauthorized automated means;
  • upload malware or content that is unlawful, infringing, or harmful;
  • use AI features to try to obtain dosing, diagnostic, or treatment advice, or to manipulate the AI to circumvent the Service’s safeguards; or
  • resell, sublicense, or commercially exploit the Service.

10. Our Intellectual Property and License to You

The Service is owned by GlucoWorks and its licensors and protected by intellectual property laws. This includes the App, software, design, text, graphics, scoring methods, and trademarks (including "SuperGlu" and "GlucoWorks").

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use the App on Apple-branded devices you own or control, for your personal, non-commercial use, as permitted by the Usage Rules in Apple’s Media Services Terms and Conditions. All rights not expressly granted are reserved.

11. Apple App Store Terms

The following applies because you obtained the App from the Apple App Store:

  • These Terms are between you and GlucoWorks only, not Apple. Apple is not responsible for the App or its content.
  • Apple has no obligation to provide maintenance or support for the App.
  • If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App. GlucoWorks is responsible for any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to any warranty, to the extent such a warranty is not disclaimed.
  • GlucoWorks, not Apple, is responsible for addressing any claims by you or a third party relating to the App or your possession or use of it. This includes product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims under consumer protection, privacy, or similar laws.
  • If a third party claims the App or your possession or use of it infringes their intellectual property rights, GlucoWorks, not Apple, is responsible for the investigation, defense, settlement, and discharge of that claim.
  • You represent that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
  • Apple and its subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance, Apple has the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
  • Questions or complaints about the App: support@glucoworks.com.

12. Privacy

Our Privacy Policy and, if it applies to you, our Consumer Health Data Privacy Policy explain how we collect, use, and share your information. Your consent to data processing is requested separately in the App and can be withdrawn as described in those policies.

13. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. THIS INCLUDES WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND QUIET ENJOYMENT.

WE DO NOT WARRANT THAT:

  • THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE;
  • ANY ESTIMATE, SCORE, PATTERN, OR AI-GENERATED CONTENT WILL BE ACCURATE OR RELIABLE;
  • DATA FROM CONNECTED SOURCES WILL BE COMPLETE, CURRENT, OR AVAILABLE; OR
  • ANY CONNECTION TO A THIRD-PARTY SERVICE WILL CONTINUE TO WORK.

YOUR USE OF THE SERVICE, AND ANY DECISION YOU MAKE BASED ON IT, IS AT YOUR OWN RISK. Some jurisdictions do not allow certain warranty exclusions, so some of the above may not apply to you.

14. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW:

(a) Excluded damages. GLUCOWORKS AND ITS MEMBERS, MANAGERS, OFFICERS, EMPLOYEES, CONTRACTORS, AGENTS, LICENSORS, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS. This applies to any decision you make about diet, medication, insulin, or treatment based on information in the Service, and it applies whether the claim is based on warranty, contract, tort (including negligence), product liability, or any other theory, even if we have been advised of the possibility of such damages.

(b) Cap. OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (i) THE AMOUNTS YOU PAID FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (ii) ONE HUNDRED U.S. DOLLARS ($100).

(c) Exceptions. Nothing in these Terms limits or excludes liability that cannot be limited or excluded under applicable law. This may include liability for death or personal injury caused by our gross negligence or willful misconduct, or for fraud. In those cases, our liability is limited to the fullest extent the law permits.

These limitations are an essential part of the bargain between you and us and apply even if a remedy fails of its essential purpose.

15. Indemnification

To the extent permitted by law, you agree to indemnify and hold harmless GlucoWorks and its members, managers, officers, employees, and agents from third-party claims, damages, and reasonable expenses (including attorneys’ fees) arising from:

  • your violation of these Terms or applicable law;
  • Your Content, including content that infringes someone else’s rights; or
  • your use of the Service on behalf of, or with data belonging to, another person.

16. Suspension and Termination

By you. You may stop using the Service and delete your account at any time in Settings → Account → Delete Account. Deleting your account does not cancel an Apple subscription. Cancel it in your Apple ID settings.

By us. We may suspend or terminate your access if:

  • you violate these Terms;
  • we are required to by law;
  • a connected third party requires it; or
  • we discontinue the Service.

Where reasonable, we will give notice. If we discontinue the Service entirely, we will give you at least 30 days’ notice where practical, so you can request a copy of your data.

What survives. Sections 1, 5, 6, 8 (as to de-identified data and feedback), and 13 through 20 survive termination.

17. Changes to These Terms

We may update these Terms. If we make material changes, we will notify you in the App and ask you to accept the updated Terms before you continue using the Service. If you do not accept them, you may delete your account. Changes do not apply retroactively to disputes that arose before the change.

18. Dispute Resolution: Binding Individual Arbitration and Class Action Waiver

18.1 Informal resolution first. Before starting arbitration or a lawsuit, you and we agree to try to resolve any dispute informally for at least 60 days. Send a written notice describing the dispute and the relief requested to info@glucoworks.com (for you) or to your account email (for us).

18.2 Agreement to arbitrate. Except as provided in Section 18.4, any dispute, claim, or controversy arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration, not in court. This includes claims based on events before these Terms took effect. The Federal Arbitration Act governs this Section.

18.3 Rules and costs. The American Arbitration Association (AAA) will administer the arbitration under its Consumer Arbitration Rules. The arbitration will take place in the county where you live, or by video or written submissions if you prefer. We will pay all AAA filing, administration, and arbitrator fees beyond the amount you would pay to file a lawsuit in court, unless the arbitrator finds your claim frivolous. The arbitrator may award the same individual relief a court could.

18.4 Exceptions. Either party may:

  • bring an individual claim in small claims court if it qualifies; or
  • seek an injunction in court for infringement or misuse of intellectual property.

18.5 Class action and jury trial waiver. YOU AND GLUCOWORKS EACH WAIVE THE RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE ACTION. Claims may be brought only on an individual basis. If this waiver is found unenforceable for a particular claim, that claim must be severed and decided in court, and the rest of this Section continues to apply.

18.6 Mass filings. If 25 or more similar arbitration demands are filed against us by or with the help of the same law firm or organization, they will be administered in batches of up to 25 demands, with one arbitrator per batch, under the AAA’s Mass Arbitration Supplementary Rules where applicable. Statutes of limitations are paused for demands awaiting a batch.

18.7 Opt-out. You may opt out of this arbitration agreement within 30 days after you first accept these Terms. To do so, email info@glucoworks.com with the subject "Arbitration Opt-Out" and include your name and account email. Opting out does not affect any other part of these Terms.

18.8 Changes. If we change this Section, you may reject the change within 30 days. If you do, the previous version continues to govern disputes between us.

19. Governing Law and Venue

These Terms are governed by the laws of the State of North Carolina, without regard to conflict-of-law principles, except that the Federal Arbitration Act governs Section 18.

For any claim not subject to arbitration, you and we consent to the exclusive jurisdiction of the state and federal courts located in North Carolina. This does not apply where your state’s law gives you the right to sue where you live.

Time limit. To the extent permitted by law, any claim must be brought within one year after it arises, or it is permanently barred.

20. General

  • Assignment. You may not assign these Terms without our consent. We may assign or transfer these Terms, including all rights and obligations, without your consent, including in connection with a merger, acquisition, reorganization, or sale of assets.
  • Entire agreement. These Terms and our Privacy Policy (including the Consumer Health Data Privacy Policy) are the entire agreement between you and us about the Service.
  • Severability. If any provision is found unenforceable, it will be enforced to the maximum extent permitted, and the rest of these Terms remain in effect.
  • No waiver. Our failure to enforce a provision is not a waiver.
  • Electronic communications. You agree to receive notices electronically, in the App or by email.
  • Force majeure. We are not responsible for delays or failures caused by events beyond our reasonable control, including outages or changes at third-party services.
  • Headings are for convenience only.
