FourHanded

Terms of Service

Last updated October 7, 2026

These terms are an agreement between you and Retainer Learning LLC, doing business as FourHanded ("FourHanded," "we," "us"). They cover your use of the FourHanded website and app, including the AI tutor we call Cara. By creating an account or using the service, you agree to them and to our Privacy Policy. If you don't agree, please don't use FourHanded.

Please read section 12. It requires most disputes to be resolved by individual binding arbitration rather than in court, and it waives class actions and jury trials. You can opt out of arbitration within 30 days of first accepting these terms.

1. What FourHanded is, and isn't

FourHanded is a study and reference tool for dental assistants and dental assisting students. Cara answers questions using an AI model, a dental assisting training curriculum, and published standards. It is educational content.

  • It is not medical, dental, or legal advice, and it is not a substitute for a dentist, an instructor, an employer's protocols, or your state dental board.
  • It does not diagnose or treat any patient. Decisions about patient care belong to the supervising dentist.
  • It is not affiliated with, endorsed by, or certified by DANB, CODA, the ADA, the CDC, OSHA, or any state board. It does not grant any credential, and using it does not qualify you to sit for any exam.
  • AI answers can be wrong, incomplete, or out of date. Verify anything that matters with your instructor, your dentist, the product's instructions, or the governing standard. What an assistant may legally do varies by state and changes over time; your state board is the final word.

2. Who can use it

You must be at least 18 to create an account. If you are 16 or 17, you may use FourHanded only through an account that a parent or legal guardian opens, pays for, and accepts these terms for; that adult is responsible for your use. FourHanded is not for anyone under 16.

You are responsible for keeping your login private and for everything done under your account. Tell us right away if you think someone else is using it.

3. Plans, questions, and payment

We sell access in plans. Prices and limits are shown on the site at the time you buy and may change for future purchases; we'll give notice before a change affects an existing subscription.

  • Individual ($9.99/month): one person, 150 questions per billing month. Renews monthly until canceled.
  • Exam Pass ($24.99 once · 90 days): one person, 500 questions to use any time within 90 days of purchase. One payment, does not renew.
  • Office ($19.99/month): one dental office, 400 questions per billing month shared by everyone the owner admits with the office code. Renews monthly until canceled. The person who buys it is the account owner and is responsible for who joins.
  • Extra questions ($5.99 for 100): a one-time purchase for people who already have a plan. They never expire, are used only after the plan's own questions are gone, and can only be used while you have an active plan. If your plan ends, they wait for you and are available again when you start any plan.

A "question" is one message to Cara. A message with a photo counts as 2. Having an answer read aloud counts as one more, so a spoken answer is 2 in total. Asking Cara to check the web counts as 2. Dictating a question with the microphone costs nothing extra. Unused plan questions do not roll over between billing periods. Limits exist to keep the service affordable; we may refuse or throttle use that looks automated or abusive.

Payments are processed by Stripe. We don't see or store your full card number. Prices don't include any taxes we may be required to collect.

Automatic renewal. The Individual and Office plans are subscriptions. They renew automatically each month, and your payment method is charged the then-current monthly price on each renewal date, until you cancel. You can cancel at any time from your account page, and cancellation takes effect at the end of the current billing month. The Exam Pass and extra questions do not renew.

4. Canceling and refunds

  • You can cancel a subscription any time from your account page. You keep access through the end of the period you've paid for; we don't prorate or refund partial periods.
  • The Exam Pass and extra questions are one-time purchases of digital access. They are non-refundable once used. If you haven't used any of it, you can request a full refund within 7 days of purchase by emailing admin@getfourhanded.com.
  • If we end the service or your access for reasons that aren't your fault, we'll refund the unused portion of what you paid.

5. Your content and how it's used

You own what you type and the photos you send. You give us permission to process them to answer you, run the service, and improve it. Questions and answers are sent to our AI provider to generate the response. We keep the text of your recent chats (the last 50) so you can reopen them; you can delete any chat yourself. We never store the photos you send; they are used to produce the answer and then discarded.

Do not send anything that identifies a patient. No names, faces, chart numbers, or dates of birth, and no images that show a patient's face or identifying features. FourHanded is a study tool, not a system for handling patient records, and we are not a HIPAA business associate for your office.

Answers from Cara are for your personal study and work. You may not resell them, publish them as a course or product, or use the service to build a competing dataset or model. You also may not share one login among several people (that's what the Office plan is for), try to bypass question limits, scrape the service, use bots or automated tools to send questions, interfere with the service or its security, or attempt to extract the underlying prompts, curriculum, or models. If you work for or are building a product that competes with FourHanded, you may not use the service.

Feedback. If you rate an answer, flag one, or send us suggestions, you agree we can use that feedback freely to fix and improve FourHanded, without any obligation or payment to you.

6. Our content

The FourHanded name, Cara, the site, the diagrams, and the curriculum behind the answers belong to Retainer Learning LLC or its licensors and are protected by copyright and trademark law. You get a personal, non-transferable license to use the service while your plan is active, and nothing more. DANB, CDA, RHS, ICE, and GC are trademarks of the Dental Assisting National Board, Inc.; other names are the property of their owners. We use them only to describe what the service helps with.

Copyright complaints. If you believe something in FourHanded infringes your copyright, email admin@getfourhanded.com with your contact information, a description of the work and where it appears in the service, a statement that you believe in good faith the use isn't authorized, a statement under penalty of perjury that you're the owner or authorized to act for them, and your physical or electronic signature. We'll review and respond.

7. Office plans

An Office plan owner may add and remove members and issue a new join code at any time. Members' chats are private to them; the owner can see each member's question count, not their conversations. If the owner cancels, every member loses access at the end of the paid period. The owner is responsible for making sure the people they admit are allowed to use the service under these terms.

8. Changes and availability

We may change, add, or remove features, and may update these terms. If a change is significant we'll post it here and, for existing subscribers, email you before it takes effect. Continuing to use the service after that means you accept the change. We work to keep FourHanded available but don't promise it will be uninterrupted or error-free.

9. Ending an account

You can close your account any time by emailing admin@getfourhanded.com. We may suspend or close accounts that break these terms, abuse the service, or create risk for other users, and in that case no refund is due. Sections 1, 5, 6, 10, 11, 12, and 14 survive after an account ends.

10. Disclaimers and limits on liability

FourHanded is provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, and non-infringement. You use the information at your own judgment and risk, and you remain responsible for complying with your employer's protocols, your state's laws, and professional standards.

To the fullest extent the law allows, Retainer Learning LLC and its owners, employees, and suppliers are not liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, data, or goodwill, arising from your use of the service. Our total liability for any claim is limited to the amount you paid us in the twelve months before the claim. Some states don't allow some of these limits, so some may not apply to you.

11. Indemnification

You agree to defend, indemnify, and hold harmless Retainer Learning LLC and its owners, employees, contractors, and suppliers from any claims, losses, damages, and expenses (including reasonable attorneys' fees) that arise from your breach of these terms, your misuse of the service, anything you submit to the service (including patient information sent in violation of section 5), or your violation of any law or of someone else's rights. We may take over the defense of any such claim at our own expense, and you agree to cooperate with us if we do.

12. Disputes: informal resolution, arbitration, and class-action waiver

Please read this section carefully. It affects your legal rights, including your right to go to court and to have a jury decide your claim.

12.1 Talk to us first

Before starting arbitration or a lawsuit, you agree to email us at admin@getfourhanded.com with your name, the email on your account, a description of the problem, and what you'd like us to do about it. We'll do the same by emailing you. We both agree to try in good faith to resolve the matter informally for 30 days after that notice before taking any formal step.

12.2 Binding arbitration

If we can't resolve it informally, you and Retainer Learning LLC agree that any dispute, claim, or controversy arising out of or relating to these terms or the service (including whether a claim is subject to arbitration) will be resolved by binding individual arbitration, not in court. The Federal Arbitration Act governs this section. The arbitration will be run by JAMS under its Streamlined Arbitration Rules and Procedures and, where they apply, its Consumer Minimum Standards, before a single arbitrator. The arbitrator can award the same relief a court could award to you individually. The arbitration will take place in Salt Lake County, Utah, or by phone or video if you prefer and the amount in dispute is under $10,000. If there is a conflict between the JAMS rules and this section, this section controls. Judgment on the award may be entered in any court with jurisdiction.

12.3 Fees

If you are a consumer, you won't pay more than the JAMS consumer filing fee (currently $250), and we'll pay the rest of the arbitration fees. If the arbitrator finds that a claim was frivolous or brought for an improper purpose, fees may be allocated as the JAMS rules allow. Each side pays its own attorneys' fees unless the law or the arbitrator provides otherwise.

12.4 Small claims and exceptions

Either of us may bring an individual claim in small claims court instead of arbitration if it qualifies. Either of us may also ask a court for an injunction to stop infringement or misuse of intellectual property, or unauthorized access to the service.

12.5 No class actions, no jury trials

You and Retainer Learning LLC agree that each of us may bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any class, consolidated, or representative action. The arbitrator may not consolidate more than one person's claims or preside over any form of class or representative proceeding. To the extent any claim does proceed in court rather than in arbitration, you and we each waive the right to a jury trial. If a court decides that this class-action waiver can't be enforced for a particular claim, then that claim (and only that claim) will proceed in court under section 12.7 rather than in arbitration.

12.6 Opting out

You can opt out of arbitration by emailing admin@getfourhanded.com within 30 days after you first create an account, with the subject "Arbitration opt-out" and your name and account email. If you opt out, this section 12 will not apply to you, but the rest of these terms will. Opting out has no effect on any other part of your relationship with us.

12.7 Governing law and courts

These terms are governed by the laws of the State of Utah, without regard to conflict-of-law rules, and by the Federal Arbitration Act. Any claim that isn't subject to arbitration will be brought only in the state or federal courts located in Salt Lake County, Utah, and you consent to their jurisdiction. Any claim must be brought within one year after it arises, or it is permanently barred, to the extent the law allows.

13. If you got FourHanded from an app store

If you downloaded FourHanded through the Apple App Store or Google Play, the following also applies. These terms are between you and Retainer Learning LLC only, not with Apple or Google (each an "app store provider"), and the app store provider is not responsible for FourHanded or its content. Your license to the app is limited to using it on devices you own or control, as allowed by the app store provider's usage rules. We, not the app store provider, are responsible for maintenance and support, for any product warranty (to the extent one isn't disclaimed), for addressing any claim that the app fails to conform to a legal or regulatory requirement, and for any claim that the app infringes someone's intellectual property. If the app fails to conform to any applicable warranty, you may notify the app store provider and it may refund the purchase price to you; the app store provider has no other warranty obligation. You represent that you are not located in a country subject to a U.S. government embargo and are not on any U.S. government list of prohibited or restricted parties. The app store provider is a third-party beneficiary of these terms and may enforce them against you.

14. General

  • Entire agreement. These terms and the Privacy Policy are the whole agreement between you and us about the service, and replace any earlier agreements.
  • Severability. If any part of these terms is found unenforceable, the rest still applies, and the unenforceable part will be modified to the minimum extent needed to make it enforceable.
  • No waiver. If we don't enforce a part of these terms right away, that doesn't mean we've given up the right to enforce it later.
  • Assignment. You can't transfer your account or these terms to anyone else. We may assign them to a successor or an affiliate, including in a sale or merger of the business.
  • Things outside our control. We're not liable for delays or failures caused by events beyond our reasonable control, such as outages at our providers, internet failures, natural disasters, or government actions.
  • Notices and electronic communications. We'll send notices to the email on your account, and you agree to receive them electronically. Notices to us go to admin@getfourhanded.com.
  • No third-party beneficiaries. Except for the app store providers in section 13, no one other than you and us has any rights under these terms.
  • California residents. Under California Civil Code section 1789.3, you may contact the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by phone at (800) 952-5210.
