MyoGo Terms of Use & End User License Agreement

Version: 1.6

Effective date: September 15, 2026

Last updated: September 22, 2026

These Terms of Use and End User License Agreement (the "Terms") are a binding agreement between you and Adecastic LLC, a Pennsylvania limited liability company with its registered office at 502 W 7th St, Ste 100, Erie, PA 16502, USA ("Adecastic," "we," "us," or "our"), governing your use of the MyoGo mobile application, including all related content, features, updates, and services (the "App").

By affirmatively accepting these Terms in the grown-up setup flow, you agree to them. If you do not agree, do not continue setup or use the App. A child's use of the App is not a substitute for the adult's acceptance.

PLEASE READ SECTION 3 ("NOT MEDICAL ADVICE") AND SECTION 4 ("SAFE USE") CAREFULLY. THEY CONTAIN IMPORTANT HEALTH AND SAFETY INFORMATION. SECTIONS 12–15 INCLUDE WARRANTY DISCLAIMERS, LIABILITY LIMITS, AND INDIVIDUAL ARBITRATION TERMS, SUBJECT TO APPLICABLE LAW. SECTION 15 INCLUDES SMALL-CLAIMS AND OTHER EXCEPTIONS AND A 30-DAY ARBITRATION OPT-OUT.

1. Who may agree to these Terms; children's use

You must be at least 18 years old and have the legal capacity to enter into contracts to accept these Terms. The App is intended to be set up, purchased, and managed only by a parent or legal guardian. When you accept these Terms in the App, the App may record the Terms version and the date of your acceptance locally on your device.

During setup, a brief parent check protects the first permission request or external link. Before the subscription screen, the parent or legal guardian attests to that role, creates a separate MyoGo parent PIN, and saves a one-time recovery code. If earlier protected actions were skipped, the parent check appears before PIN creation. Choose a PIN the child does not know and keep the recovery code where the child cannot access it. The parent PIN restricts purchasing, external links, permission changes, and parent controls. A forgotten-PIN reset always requires the saved recovery code and may also ask iOS to perform device-owner authentication as an additional check when available. These controls support, but do not replace, your supervision of the child's device use.

If you allow a child to use the App, you represent and warrant that you are that child's parent or legal guardian, you authorize the child's supervised use, and you are responsible for your own supervision and obligations under these Terms. These Terms are an agreement between Adecastic and you. They do not claim to waive a child's independent rights or bind a child where the law does not permit it.

2. What MyoGo is

MyoGo is intended solely as a general wellness and educational practice tool. It provides video demonstrations of oral and facial exercises commonly used in myofunctional practice, playful camera- and sound-guided feedback, games, and progress tracking, designed to help children build a fun daily practice habit. Every child follows the same balanced exercise progression; the age selected during setup may adjust the starting game pace, but it does not create an individualized health program.

3. NOT MEDICAL ADVICE — READ CAREFULLY

THE APP DOES NOT PROVIDE MEDICAL CARE, MEDICAL ADVICE, DIAGNOSIS, SCREENING, OR TREATMENT OF ANY KIND.

• MyoGo is intended solely for general wellness and educational purposes. It is not intended to diagnose, cure, mitigate, prevent, screen for, monitor, or treat any disease, disorder, injury, or other medical condition. MyoGo is not offered as an FDA-cleared or FDA-approved medical device, and we do not claim medical-device authorization from another regulator.
• The App is not a substitute for care from a physician, dentist, orthodontist, speech-language pathologist, myofunctional therapist, or any other qualified professional, and does not replace any treatment plan they prescribe.
• Using the App does not create a doctor–patient, therapist–patient, or any other professional or clinical relationship between you (or your child) and Adecastic.
• The App's balanced exercise progression, progress metrics, exercise feedback, and any informational notices it displays are general educational information only. They are not a diagnosis, a clinical screening result, a risk assessment, an individualized treatment plan, or professional advice, and they may be incomplete or inaccurate for your child's situation. Setup asks only for an age from 4 through 14, an optional first name or nickname, and a preferred practice-reminder time; allowing notifications is optional. It does not ask for a date of birth or gender, and it does not ask about or use symptoms, diagnoses, health goals, professional-care status, motivators, or prior exercise experience to choose exercises. The age may adjust the starting game pace, but every child follows the same balanced exercise progression. Camera- and microphone-based feedback is approximate game feedback, not a clinical measurement.
• Adecastic does not monitor your child's use of the App. We do not review profile details, progress, or exercise performance, and we do not identify warning signs or alert you or any healthcare professional to potential health concerns. Because App information stays on your device, we generally have no way to know whether your child is experiencing a problem or needs professional care.
• Always consult a qualified professional about any question regarding your child's breathing, sleep, speech, swallowing, oral function, or overall health, before beginning this or any exercise program, and before making any decision based on anything shown in the App. Never disregard, avoid, or delay obtaining professional advice because of something you saw in the App.
• The App is not for emergencies. If your child has severe breathing difficulty, is choking, loses consciousness, has severe allergic symptoms or significant bleeding, or shows any other potentially life-threatening condition, stop using the App and call emergency services (911 in the U.S.) immediately. Do not rely on the App for emergency information or assistance.

4. Safe use; your responsibilities; assumption of risk

The App demonstrates gentle facial, tongue, lip, and breathing movements. As with any physical activity, there is some inherent risk of discomfort or injury, and results vary from child to child (we make no promise of any particular outcome).

You agree that you will:

• consult your child's healthcare provider before use if your child has any medical condition — including but not limited to recent oral surgery or a recent tongue-tie release, jaw (TMJ) conditions, breathing or airway conditions, cardiac or neurological conditions, seizure disorders, or motion or photosensitivity sensitivities — or any other known or suspected medical, dental, developmental, neurological, breathing, sleep, feeding, swallowing, speech, or musculoskeletal condition that could affect safe participation, or if you are unsure whether the exercises are appropriate;
• supervise your child's use of the App and ensure exercises are performed gently and only as demonstrated — without adding resistance, weights, objects, tools, force, breath-holding, or other modifications, unless specifically instructed by an appropriately qualified healthcare professional;
• have your child stop immediately if they experience pain, dizziness, lightheadedness, jaw discomfort, or breathing difficulty, and seek professional advice before resuming;
• ensure your child uses the device in a safe environment (seated or standing safely, not while walking, in a vehicle, or near hazards); and
• keep the device at a comfortable viewing distance and take breaks as needed.

To the extent permitted by applicable law, you acknowledge and accept the ordinary risks of voluntary physical practice when supervising use of the App. This acknowledgment does not waive liability that cannot lawfully be waived, excuse Adecastic's negligence where it cannot be excluded, or waive a child's independent rights.

5. License; restrictions

Subject to these Terms, Adecastic grants you a limited, non-exclusive, non-transferable, revocable license to download and use the App for personal, non-commercial family use on Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions — except that the App may be accessed and used by other accounts associated with you via Apple's Family Sharing or volume purchasing.

You will not (and will not permit anyone to): (a) copy, modify, translate, or create derivative works of the App or its content; (b) distribute, sell, rent, lease, sublicense, or otherwise transfer the App; (c) reverse engineer, decompile, or attempt to extract the App's source code, except to the extent such restriction is prohibited by law; (d) remove or alter any proprietary notices; (e) use the App's name, characters (including Tako), artwork, video, audio, or other content outside the App; (f) use the App to develop a competing product; (g) use the App in violation of any law; or (h) circumvent any feature gate, subscription requirement, or parental control. These restrictions do not prohibit lawful use of accessibility tools or rights that applicable law does not allow us to restrict.

6. Subscriptions, free trials, and billing

Onboarding includes short activity previews without a subscription. Ongoing guided practice, games, and sticker rewards require an active subscription, including an eligible trial. Returning families retain parent-gated access to previously saved progress, exports, and data controls without an active subscription. First-time setup and checkout do not show a Parent settings shortcut. A paid auto-renewing subscription ("MyoGo Premium") includes guided exercises, compatible games and arcade mode, rewards, and practice tracking. Completing guided daily practice is optional and is not required to access games. Daily-routine rewards and practice streaks reflect qualifying routine completion separately from game activity. Available games depend on compatible hardware and the optional camera or microphone feedback selected by the adult user. Games whose required input is unavailable are not shown. MyoGo does not offer new Premium purchases on devices that lack Apple face-tracking hardware. All purchases are processed by Apple through your Apple Account; we do not receive your payment-card details. The purchase screen and Apple confirmation show the applicable plan, billing period, localized price, and any eligible trial. Trying an onboarding preview does not start a subscription or a trial.

• Billing and renewal. Subscription fees are charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically at the then-current price for the same term unless canceled at least 24 hours before the end of the current period. Your Apple Account is charged for renewal within 24 hours before the current period ends.
• Free trials. If a free trial is offered, the trial's length and terms are shown at purchase. Unless you cancel at least 24 hours before the trial ends, the subscription begins automatically and your Apple Account is charged. Trial eligibility and any forfeiture of remaining trial time are determined by Apple and the offer shown at purchase. Introductory offers are generally limited to one per subscription group for an eligible Apple Account; a trial is not guaranteed.
• Canceling. Use Manage Subscription in the parent area or iPhone Settings → your name → Subscriptions → MyoGo → Cancel Subscription. You can also follow Apple's cancellation instructions. Cancel at least 24 hours before the renewal or trial end to avoid the next charge. For a paid period, access generally continues until the expiration Apple shows; free-trial access may end when you cancel. Apple's confirmation and any applicable local cancellation rights govern. Deleting the App, using Erase All Data, or dismissing a reminder does not cancel a subscription.
• Price changes. If the subscription price changes, Apple will notify you as required and, where required, seek your consent before charging the new price.
• Refunds and consumer rights. Request an App Store refund through Apple's refund process. Eligibility depends on the circumstances and applicable law. Nothing in these Terms removes a mandatory withdrawal, cancellation, refund, or other consumer remedy. Contact support@adecastic.com if you need help with a billing or access problem.
• Family Sharing. If Family Sharing is shown as included on the App Store product page or purchase screen, eligible subscription access may be shared through Apple's Family Sharing, subject to the purchaser's Apple Account settings and Apple's rules. Do not assume Family Sharing is available unless Apple identifies it as included for the subscription.
• Trial reminders. A local trial-ending reminder is optional and depends on device permissions, settings, and timing. It does not cancel a subscription, guarantee delivery, or replace the billing dates shown by Apple.
• Feature changes. We may change, add, or remove features of the App over time; we will not materially reduce the core functionality of an active paid subscription during a period you have already paid for without providing the remedies required by applicable law.

7. Intellectual property

The App and all of its content — including the Tako character, artwork, animations, video demonstrations, audio, music, text, exercise sequences, software, and trademarks — are owned by Adecastic or its licensors and are protected by intellectual property laws worldwide. Except for the limited license in Section 5, no rights are granted to you. "Adecastic," the Tako character, and associated Adecastic-owned logos, artwork, and brand elements are trademarks or other proprietary assets of Adecastic LLC, and Adecastic claims trademark rights in "MyoGo" to the extent provided by applicable law.

If you voluntarily send product feedback or suggestions, you allow us to use them without payment to improve or promote the App. This permission does not grant us a right to publish private correspondence, a child's information, your name or likeness, or another person's protected content; the Privacy Policy continues to apply.

8. Privacy

Our MyoGo Privacy Policy — available where these Terms are posted and from the App — explains how the App, the MyoGo website, and communications with us handle information. The App keeps child profiles and practice records locally and processes live camera and microphone feedback on device without saving or uploading recordings. Apple handles subscription information; website requests and information you deliberately send us are described separately in the policy. Acknowledging the policy does not authorize new data uses that require separate consent under applicable law.

9. Progress exports

The App lets you export a summary of practice progress to share with anyone you choose. Review an export before sending it and choose its recipients carefully. It may contain child information. Previously shared copies are controlled by their recipients and are not recalled when you erase App data. Exports are descriptions of App activity, not clinical assessments or proof of medical progress.

10. Third-party terms

You must comply with any applicable third-party terms when using the App — for example, Apple's Media Services Terms and Conditions and your wireless carrier's data agreement.

11. Changes to the App or these Terms

We may update these Terms from time to time. If we make material changes, we will provide notice in the App or by other reasonable means, and the updated Terms will apply on the date shown above after such notice. Your continued use of the App after the update takes effect constitutes acceptance, except that if we materially modify Section 15 (governing dispute resolution, arbitration, or the class-action waiver), we will require your affirmative acceptance of the revised Terms before your further use of the App, and, unless otherwise required by law, those modifications will not apply to any dispute that arose before the change took effect. If you do not agree to updated Terms, stop using the App and cancel any subscription. No changes will retroactively reduce protections applicable to disputes arising before the change.

12. DISCLAIMER OF WARRANTIES

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. ADECASTIC DISCLAIMS ALL WARRANTIES AND CONDITIONS, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, QUIET ENJOYMENT, AND NON-INFRINGEMENT. ADECASTIC DOES NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, THAT DEFECTS WILL BE CORRECTED, THAT THE APP'S FEEDBACK, CONTENT, OR SUGGESTED PRACTICE INFORMATION WILL BE ACCURATE, COMPLETE, OR SUITABLE FOR YOUR CHILD, OR THAT ANY EXERCISE DEMONSTRATION, AUDIOVISUAL EXAMPLE, CHARACTER ANIMATION, TIMING CUE, SUGGESTED REPETITION COUNT, OR FEEDBACK SIGNAL WILL BE APPROPRIATE, SAFE, OR EFFECTIVE FOR EVERY CHILD, AND ADECASTIC MAKES NO WARRANTY REGARDING ANY HEALTH, DEVELOPMENTAL, OR OTHER OUTCOME.

Some jurisdictions do not allow the exclusion of implied warranties, so some of the above exclusions may not apply to you. You may have additional rights that vary by jurisdiction.

13. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW: (A) IN NO EVENT WILL ADECASTIC OR ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, GOODWILL, OR PROFITS, ARISING OUT OF OR RELATING TO THESE TERMS OR THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES; AND (B) ADECASTIC'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE APP WILL NOT EXCEED THE GREATER OF (i) THE AMOUNTS YOU PAID FOR THE APP IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY, OR (ii) FIFTY U.S. DOLLARS (US$50).

The limitations in this section do not apply to liability that cannot be limited under applicable law — including, where applicable, liability for death or personal injury caused by negligence, gross negligence, willful misconduct, or fraud — and nothing in these Terms limits your non-waivable statutory rights as a consumer. Each provision of Sections 12–14 is an essential basis of the bargain, and each applies even if a limited remedy fails of its essential purpose.

14. Indemnification

To the maximum extent permitted by applicable law, you agree to indemnify and hold harmless Adecastic and its officers, directors, employees, and agents from and against any claims, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your breach of these Terms; (b) your violation of law or the rights of a third party; or (c) use of the App by a child under your care other than as permitted by these Terms and the App's instructions. This section does not apply to the extent a claim arises from Adecastic's own negligence, willful misconduct, or breach of these Terms, and does not limit any non-waivable consumer rights.

15. Governing law; dispute resolution; arbitration; class waiver

Please read this section carefully — it affects your rights.

These Terms are governed by the laws of the Commonwealth of Pennsylvania, without regard to conflict-of-laws rules, except that the Federal Arbitration Act governs Section 15's arbitration provisions. If you are a consumer resident of a jurisdiction whose law grants you non-waivable protections, you retain those protections.

• Informal resolution. Contact support@adecastic.com with a description of the dispute so we can try to resolve it. If it remains unresolved after 60 days, either party may proceed as set out below. This process does not prevent a filing needed to preserve a legal deadline, a permitted small-claims action, an urgent remedy available by law, or a complaint to a government authority.
• Binding arbitration. Except as provided below, any dispute arising out of or relating to these Terms or the App will be resolved by final and binding arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, before a single arbitrator, rather than in court. The arbitration will be conducted in English, by videoconference or, if an in-person hearing is required, in the county where you reside. Payment of filing and arbitrator fees will be governed by the AAA's Consumer Rules. The arbitrator has exclusive authority to resolve any dispute about the interpretation, applicability, or enforceability of this arbitration agreement, and may award the same individual relief a court could — except that a court, not the arbitrator, will decide (i) whether an agreement to arbitrate was formed, (ii) any dispute about whether you validly exercised the 30-day opt-out below, and (iii) whether the class action and jury waiver below is enforceable.
• Exceptions. Either party may bring an eligible individual claim in small claims court or seek injunctive or equitable relief in court for actual or threatened infringement or misuse of intellectual property. Nothing prevents you from reporting to or cooperating with a government agency, seeking a remedy that cannot lawfully be subjected to arbitration or waived, or exercising a non-waivable right to a local court. If AAA declines to administer a dispute under its Consumer Rules and the parties do not agree on a lawful alternative, either party may pursue that dispute in a court with jurisdiction. AAA's consumer resources explain its rules and consumer protections.
• Class action and jury waiver. To the fullest extent permitted by law, disputes will be resolved only on an individual basis. Neither party may participate in a class, collective, consolidated, or representative action, and both parties waive any right to a jury trial. If this class waiver is found unenforceable as to a particular claim, that claim (and only that claim) must proceed in court, and the remainder in arbitration.
• 30-day opt-out. You may opt out of this arbitration agreement and class waiver by emailing support@adecastic.com within 30 days of first accepting these Terms, stating your name and that you opt out of arbitration. Opting out does not affect any other provision of these Terms. A previous valid arbitration opt-out remains effective.
• Courts. For any dispute not subject to arbitration, you and Adecastic consent to the exclusive jurisdiction and venue of the state and federal courts located in Erie County, Pennsylvania, except that you may litigate in your local courts where required by applicable consumer law.

16. Apple-specific terms (App Store)

The following terms are required by Apple and apply to your use of the App downloaded from the Apple App Store:

• Acknowledgement. These Terms are concluded between you and Adecastic only — not with Apple Inc. ("Apple") — and Adecastic, not Apple, is solely responsible for the App and its content. These Terms do not provide usage rules that conflict with the Apple Media Services Terms and Conditions.
• Scope of license. The license granted to you is limited to a non-transferable license to use the App on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the App may be accessed and used by other accounts associated with the purchaser via Family Sharing or volume purchasing.
• Maintenance and support. Adecastic is solely responsible for providing any maintenance and support for the App. Apple has no obligation to furnish any maintenance or support services for the App.
• Warranty. Adecastic is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to any warranty are Adecastic's sole responsibility.
• Product claims. Adecastic, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession and/or use of the App, including: (i) product liability claims; (ii) any claim that the App fails to conform to an applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, or similar legislation. These Terms do not limit Adecastic's liability to you beyond what is permitted by applicable law.
• Intellectual property claims. In the event of any third-party claim that the App, or your possession and use of the App, infringes that third party's intellectual property rights, Adecastic, not Apple, is solely responsible for the investigation, defense, settlement, and discharge of the claim.
• Legal compliance. You represent and warrant that (i) you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
• Third-party beneficiary. You and Adecastic acknowledge and agree that Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and that upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

17. Termination

These Terms are effective until terminated. Your rights under these Terms terminate automatically if you fail to comply with them; upon termination, you must stop using the App and delete it. We may suspend or discontinue the App (or part of it), subject to applicable law and the paid-feature commitments in Section 6. If we permanently discontinue paid access during a period you have paid for, contact us and use Apple's refund process for prepaid, unused fees. This is not your exclusive remedy where the law provides others, and we do not promise a result from a refund process controlled by Apple. Sections 3, 4, 7, and 12–19 survive termination.

18. General

• Entire agreement. These Terms (with the Privacy Policy) are the entire agreement between you and Adecastic regarding the App and supersede all prior agreements on that subject.
• Severability. If any provision is held unenforceable, it will be enforced to the maximum extent permissible and the remaining provisions will remain in full force.
• No waiver. Our failure to enforce any provision is not a waiver of it.
• Assignment. You may not assign these Terms. We may assign them in connection with a merger, acquisition, or sale of assets, provided the assignee assumes our obligations.
• Export. You will comply with all applicable U.S. and international export laws in connection with the App.
• California notice. Under California Civil Code § 1789.3, California users are entitled to know that they may file grievances and complaints with 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.
