MyBest24 Terms of Use

Effective Date: May 18, 2026

PLEASE READ THESE TERMS CAREFULLY. THEY GOVERN YOUR USE OF THE SERVICE AND INCLUDE PROVISIONS THAT LIMIT OUR LIABILITY (SECTION 11), DISCLAIM WARRANTIES (SECTION 10), AND REQUIRE INDIVIDUAL ARBITRATION OF DISPUTES AND WAIVE PARTICIPATION IN CLASS ACTIONS (SECTION 13). YOU MAY OPT OUT OF ARBITRATION WITHIN THIRTY (30) DAYS OF FIRST ACCEPTANCE OF THESE TERMS, AS DESCRIBED IN SECTION 13.

These Terms of Use ("Terms") form a binding agreement between you and MyBest24 ("we," "us," or "our") regarding your use of the MyBest24 service, including the website at mybest24.com and the MyBest24 application (collectively, the "Service"). The MyBest24 Privacy Policy is incorporated into these Terms by reference.

1. Acceptance of Terms

By creating an account, accessing, or using the Service, you agree to be bound by these Terms and by the Privacy Policy. If you do not agree, you may not use the Service. You represent that you are at least eighteen (18) years of age and that you have the legal capacity to enter into a binding contract. If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization.

2. The Service

The Service is a wellness self-tracking and goal-setting tool. The Service is not intended to provide medical advice, mental-health treatment, diagnosis, or therapy. We may modify, suspend, or discontinue features at our discretion. For material removal of paid features, we will provide reasonable advance notice.

3. Medical and Wellness Disclaimer

The Service is provided for general wellness and informational purposes only. The Service is not medical advice, mental-health treatment, diagnosis, or therapy and is not a substitute for professional care. Information and features provided through the Service, including mood logs, reflections, weight entries, food entries, fitness entries, scoring, and any tips, suggestions, or insights generated within the Service or by the "Cally" feature, are for informational and self-awareness purposes only. The Service is not intended to diagnose, treat, cure, or prevent any disease, mental-health condition, or eating disorder.

Always consult a qualified healthcare or mental-health provider before making decisions about your health, including changes to diet, exercise, medication, or treatment plans. Never disregard, avoid, or delay seeking professional medical or mental-health advice because of something you read or did within the Service.

The Health Team feature permits you to share data with a coach or therapist whom you select. Use of the Health Team feature does not create a doctor-patient, therapist-patient, or other professional relationship between you and MyBest24, or between you and any provider through MyBest24. Any professional relationship is between you and your provider directly and is governed by your provider's licensure and any separate agreements between you and your provider. We act solely as a conduit for the data you choose to share.

If you are experiencing a mental-health crisis or medical emergency, do not rely on the Service. In the United States, contact the Suicide and Crisis Lifeline by calling or texting 988, contact emergency services by calling 911, or go to the nearest emergency room. The Crisis Text Line may be reached by texting HOME to 741741. The National Alliance for Eating Disorders helpline may be reached at 1-866-662-1235.

[LAWYER REVIEW REQUIRED] — Conservative wellness-app boilerplate. A licensed attorney should review and adapt for California-specific duty-of-care language and confirm crisis-resource accuracy at time of publication.

4. Accounts

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. One person per account. You must provide accurate information at registration, including a current email address through which we may contact you. You must promptly notify us at hello@mybest24.com of any unauthorized access. We may suspend or terminate accounts in accordance with Section 15.

5. Acceptable Use

You agree that you will not, and will not permit any third party to:

1. reverse-engineer, decompile, disassemble, or scrape the Service;
2. use the Service to harass, harm, surveil, or coerce another person, including misuse of the Health Team feature to monitor a person without that person's full informed consent;
3. upload or transmit any unlawful, infringing, harmful, or malicious content, or any content designed to harm our systems or other users;
4. probe, scan, or attempt to compromise our infrastructure;
5. impersonate another user, person, or entity;
6. use the Service to provide healthcare, therapy, or any other licensed service to others without holding the appropriate license;
7. use the Service to develop a competing product or to create a derivative dataset of MyBest24 content;
8. circumvent any technical or security measures we implement.

Violations may result in suspension or termination of your account and may give rise to civil or criminal liability.

6. Health Team Feature

6.1 Your Control. You and only you determine who receives a Health Team share link and which categories of your data are visible. You may revoke access at any time. Tokens automatically expire ninety (90) days after issuance.

6.2 Conduit Status. When you share data via Health Team, MyBest24 acts as a conduit and is not a party to the relationship between you and the recipient. We are not responsible for the recipient's use of data once disclosed. Your relationship with the recipient is governed by their professional and legal obligations and any agreement you have with them.

6.3 Recipient Acknowledgment. Recipients accessing data through Health Team must accept a separate "Health Team Recipient" notice prior to viewing data. That notice addresses acceptable use, confidentiality, and the recipient's obligation to comply with their own professional and legal requirements (including HIPAA where applicable).

6.4 HIPAA. MyBest24 is not currently a HIPAA-covered entity and does not currently execute Business Associate Agreements. Licensed providers should consult their own compliance advisors.

6.5 Beta Status. The Health Team feature is currently in beta. Functionality may change. We may modify or discontinue beta features with reasonable notice. Paid coach and therapist features are governed by Section 9.

6.6 Coach Partner Program Relationships. A coach who participates in our Coach Partner Program may invite you to establish an ongoing coaching relationship through the Service. Such relationships use the same eight-category data-sharing model described above in this Section 6 — you control which categories of your data the coach can see, and you may revoke access at any time. The Coach Partner Program itself is governed in part by Section 9 (MyBest24 Pro). Coaches in the Coach Partner Program are independent contractors, not employees, agents, or partners of MyBest24; see Section 9.13.

6.7 Leaderboards and Public Display. MyBest24 may operate a Coach Leaderboard that ranks coaches participating in the Coach Partner Program by criteria we determine, such as the number of active paying clients each coach has. The Coach Leaderboard counts users for the purpose of ranking coaches but does not publicly identify individual users by name. From time to time we may also introduce user-facing leaderboards, public displays, or community-facing features. Any such user-facing leaderboard or public ranking would identify users only by a username — a pseudonymous handle associated with your account — and would not publicly display your real name, email address, or other personally identifying information. We will provide appropriate notice and any opt-in or opt-out controls when such features launch. Achievement artifacts you may share from your own account, such as milestone summaries or streak completions, are shared only at your express initiation through Service-provided sharing features.

7. Your Content

You retain ownership of all data and content you create within the Service ("Your Content"). You grant us a limited, worldwide, royalty-free license to host, store, transmit, display, and process Your Content solely as necessary to operate the Service for you and to fulfill the sharing choices you make through Health Team. This license terminates when you delete Your Content or your account, except for backup copies that age out in accordance with our Privacy Policy. We do not use Your Content to train any artificial intelligence or machine learning model.

8. Our Content

The Service, including the application, brand, source code, design, the "Cally" character, the scoring system, the Health Team feature, and all related text, graphics, logos, and other intellectual property ("Our Content"), is owned by MyBest24 and its licensors. All rights are reserved. We grant you a limited, personal, non-transferable, non-sublicensable, revocable license to use the Service for your own personal wellness tracking. You may not copy, redistribute, modify, reverse-engineer, or create derivative works of Our Content.

9. MyBest24 Pro

MyBest24 Pro is the optional paid tier of the Service. This Section 9 governs paid subscriptions and supplements the rest of these Terms.

The free tier of the Service is available indefinitely at no cost and includes: the daily twenty-four-box view and event scheduling; all non-fitness icon categories and a core set of fitness icons; daily logging; basic streaks; reflection tools; weight tracking; the ability to connect with a coach and to view programs assigned to you by your coach; the ability to check off coach-assigned workouts on an ongoing basis (see Section 9.5); and sixty (60) days of viewable history. The Pro tier adds: the full premium animated fitness icon library; long-term longitudinal analytics and trend insights; weekly insights and story-recap features; milestone snapshots; unlimited viewable history and data export; premium themes and advanced customization; and additional Pro features we may add over time. We may add features to either tier, move features between tiers, or remove features over time, with reasonable advance notice for any material change.

9.1 Plans and Pricing. MyBest24 Pro is offered at nine dollars and ninety-nine cents ($9.99) United States dollars per month, billed monthly, or fifty-nine dollars and ninety-nine cents ($59.99) United States dollars per year, billed annually. Prices do not include applicable taxes, which will be added at checkout where required by law. Prices are quoted in United States dollars; local-currency conversion, where applicable, is performed by our payment processor at the rate in effect at the time of charge.

9.2 Billing and Automatic Renewal. When you start a paid subscription, your payment method is charged immediately for the first billing period. Your subscription automatically renews at the end of each billing period (monthly or annual, as you selected) until you cancel. Each renewal charges the same payment method for the same amount applicable at the time of renewal, subject to Section 9.9 (Price Changes). The renewal date is the anniversary of the start date of your then-current billing period.

9.3 No Trial for Direct Signups. We do not offer a paid trial or low-cost introductory period for direct signups (signups not made through a Coach Partner Program invitation). At signup, your options are a free account or an immediate paid subscription. You may use the free tier indefinitely at no charge before deciding whether to subscribe.

9.4 Coach-Comped Trial. If you accept a formal invitation from a coach participating in the Coach Partner Program, you may receive a thirty (30) day Pro trial at no cost and with no payment method required (a "Coach-Comped Trial"). The Coach-Comped Trial is granted no more than one time per user account, ever, regardless of how many coaches invite you. At the end of the thirty (30) day trial, your account reverts to the free tier unless you elect to subscribe under Section 9.1. No automatic charge occurs at trial end because no payment method was collected. We send reminder communications by email before trial end.

9.5 Post-Trial and Post-Cancellation Access to Coach-Assigned Content. If you cancel a paid subscription, or if a Coach-Comped Trial ends without conversion to a paid subscription, you retain the ability to view and check off workouts and programs assigned to you by a coach for as long as your underlying coaching relationship remains active. Only insight-oriented Pro features — including but not limited to long-term analytics, weekly insights, milestone snapshots, history beyond sixty (60) days, and the premium animated exercise library — become unavailable on the free tier. Data you previously logged is not deleted and becomes accessible again if you resubscribe.

9.6 Cancellation. You may cancel your paid subscription at any time through your account settings within the Service, reachable in two clicks or fewer from the application home. Cancellation takes effect at the end of your then-current billing period; you retain Pro features through that date. No further charges are made after cancellation. You may also pause your subscription for thirty (30), sixty (60), or ninety (90) days; during a pause, you are not charged, and at the end of the pause, billing automatically resumes unless you have canceled or extended the pause. If you request deletion of your account (Section 15.1) while you have an active paid subscription, your subscription is automatically canceled at the end of the then-current billing period under this Section 9.6; no further charges are made, and you retain Pro features through that end date, after which your account and data are removed in accordance with Section 15.3 and the Privacy Policy.

9.7 Refunds. Monthly subscriptions are non-refundable for partial billing periods; if you cancel a monthly subscription mid-period, you retain Pro access through the end of the period but are not refunded for unused days. Annual subscriptions may be refunded in full within fourteen (14) days of initial purchase or annual renewal by sending a request to hello@mybest24.com with "Refund Request" in the subject line. Outside the fourteen (14) day window, annual refunds are at our discretion. Where applicable law requires refunds that exceed this policy, we will comply with the law.

9.8 Failed Payments and Dunning. If a renewal payment fails, our payment processor will attempt automatic retries over approximately one to three weeks. During an initial grace period of fourteen (14) days from the first failed payment, your Pro access continues. If the payment remains uncaptured at the end of the fourteen (14) day grace period, your Pro features are suspended pending successful payment, even if retries are still in progress. If all retries fail, your subscription is canceled and your account reverts to the free tier in accordance with Section 9.5.

9.9 Price Changes. We may change the price of MyBest24 Pro for new subscribers at any time. For existing subscribers, we will provide at least thirty (30) days' advance notice of any price increase by email to the address associated with your account. You may cancel before the price change takes effect if you do not accept the new price; failure to cancel constitutes acceptance.

9.10 Annual Renewal Reminder. For annual subscriptions, we will send a reminder by email to the address associated with your account at least thirty (30) days before each annual renewal date, restating the renewal amount and explaining how to cancel.

9.11 Payment Processing. Payment is processed by Stripe, Inc. ("Stripe"). We do not store full payment card numbers or other sensitive payment instrument data. Stripe's handling of your payment information is governed by Stripe's privacy policy and terms of service. By subscribing, you authorize us and Stripe to charge your payment method in accordance with this Section 9.

9.12 Web-Only Payments. Paid subscriptions are processed exclusively through our web application at mybest24.com. We do not currently offer subscriptions through the Apple App Store, Google Play, or any other third-party in-application purchase system. If we add native mobile applications in the future, subscriptions purchased through those channels may be subject to additional terms imposed by the relevant platform and may differ from those set forth in this Section 9.

9.13 Coach Partner Program; Independent Contractor Status. Coaches who participate in our Coach Partner Program — including any sub-tier such as the "Founding Coach Circle" — are independent contractors, not employees, agents, partners, or joint venturers of MyBest24. Your coaching relationship is between you and your coach. The terms governing coaches' participation in the Coach Partner Program are set forth in a separate Coach Partner Program Agreement to which you are not a party and which does not affect your rights under these Terms. We facilitate the platform on which coach-client interactions occur; we do not review, approve, supervise, or guarantee the specific content, methods, or outcomes of any coach's programs. Sections 3 (Medical and Wellness Disclaimer) and 10 (Disclaimer of Warranties) apply in full to any content or instructions you receive through a coaching relationship.

9.14 Disputes Concerning Charges. If you believe a charge was made in error, contact us at hello@mybest24.com with "Billing Question" in the subject line before initiating a chargeback with your card issuer. We will work in good faith to resolve the issue directly. Chargebacks initiated without first contacting us may result in suspension of your account pending resolution.

9.15 Modification or Discontinuation of Pro Features. We may modify, suspend, or discontinue specific Pro features with reasonable advance notice. If we discontinue a material Pro feature you actively use, we will provide reasonable advance notice and, where the discontinuation occurs mid-billing-period and materially reduces the value of your subscription, a prorated refund of the remaining portion of that period.

9.16 Acknowledgment of Recurring Billing. You acknowledge and agree that (a) your subscription is a recurring charge that will continue until you cancel; (b) you have been clearly informed of the price, the billing frequency, and the date of the first charge before completing checkout; and (c) you may cancel at any time through your account settings as described in Section 9.6. This Section 9.16 is intended to satisfy applicable automatic-renewal disclosure requirements, including those of California Business and Professions Code sections 17600 through 17606.

[LAWYER REVIEW REQUIRED] — Subscription, billing, and refund terms drafted from internal policy decisions. A licensed attorney should review for: (i) California Automatic Renewal Law (Bus. & Prof. Code §§ 17600-17606) compliance, including the acknowledgment-of-terms checkbox before checkout and the form and timing of post-purchase confirmation; (ii) any state-specific consumer-protection refund minimums (e.g., FTC ROSCA, state-level "Click-to-Cancel" rules); (iii) appropriate scope of the Coach Partner Program independent-contractor framing in Section 9.13; (iv) interaction with the limitation-of-liability cap in Section 11 for paid users; (v) whether a separate at-checkout acceptance gate is preferable to relying on continued-use acceptance for these paid terms.

10. Disclaimer of Warranties

The Service is provided "as is" and "as available," without warranty of any kind, express or implied. To the maximum extent permitted by applicable law, MyBest24 disclaims all warranties, including, without limitation, the implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranties arising from course of dealing or usage of trade.

We do not warrant that the Service will be uninterrupted, error-free, secure against unauthorized access, or free of viruses or other harmful components, or that any defects will be corrected. We do not warrant that the Service will produce specific outcomes, including, without limitation, any health, wellness, fitness, or mental-health outcomes. You use the Service at your own risk.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you.

[LAWYER REVIEW REQUIRED] — Conservative "AS IS" boilerplate. A licensed attorney should confirm California-compliant magic-word phrasing and any consumer-protection carve-outs.

11. Limitation of Liability

To the maximum extent permitted by law, in no event will MyBest24 or its officers, directors, employees, or agents be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including, without limitation, damages for loss of profits, loss of data, loss of goodwill, or any other intangible losses, arising out of or relating to your use of or inability to use the Service, even if MyBest24 has been advised of the possibility of such damages.

In no event will MyBest24's total cumulative liability to you for all claims arising out of or relating to the Service exceed the greater of (a) the total amount you paid to MyBest24 in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) one hundred United States dollars (US $100).

The foregoing limitations do not apply to liability arising from: (i) gross negligence or intentional misconduct; (ii) fraud; (iii) death or bodily injury caused by our negligence to the extent applicable law does not permit such limitation; or (iv) any other liability that cannot be limited under applicable law.

Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you. In such jurisdictions, our liability is limited to the maximum extent permitted by law.

[LAWYER REVIEW REQUIRED] — Conservative cap structure. A licensed attorney should set the appropriate cap amount and confirm compliance with California Civil Code section 1668.

12. Indemnification

You agree to defend, indemnify, and hold harmless MyBest24 and its officers, directors, employees, and agents from and against any claims, damages, liabilities, losses, costs, or expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your use of the Service in violation of these Terms or applicable law; (b) Your Content; (c) your misuse of the Health Team feature, including unauthorized surveillance or coercion of another person; or (d) your violation of any third-party right, including any intellectual-property or privacy right. We may, at our sole discretion, assume the defense of any matter for which you owe us indemnification, in which case you will cooperate with us in such defense. You may not settle any matter for which we owe indemnification without our prior written consent.

[LAWYER REVIEW REQUIRED] — Standard structure. A licensed attorney should confirm scope and any required California consumer carve-outs.

13. Dispute Resolution; Arbitration; Class Action Waiver

Please read this section carefully. It affects your legal rights, including your right to a jury trial and your right to participate in a class action.

13.1 Informal Resolution. Before initiating arbitration, you agree to send a written description of your dispute to hello@mybest24.com, including the relief you seek. We agree to do the same with respect to any dispute we have against you. Many disputes can be resolved within thirty (30) days of such notice.

13.2 Binding Arbitration. Except as set forth in Section 13.4, any dispute, claim, or controversy between you and MyBest24 arising out of or relating to these Terms, the Service, or your relationship with MyBest24 will be resolved exclusively by binding individual arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules. The arbitration will be conducted in the federal judicial district of your residence. For claims under twenty-five thousand United States dollars (US $25,000), arbitration may be conducted by phone or video at your election. The arbitrator's decision will be final and binding.

13.3 Class Action Waiver. You and MyBest24 each agree that disputes will be resolved only on an individual basis and not on a class, consolidated, or representative basis. Neither you nor MyBest24 may bring a claim as a plaintiff or class member in any class, consolidated, or representative action. The arbitrator may not consolidate more than one person's claims and may not preside over any form of representative or class proceeding. If this class-action waiver is held unenforceable as to a particular claim or remedy, that claim or remedy must be severed and brought in a court of competent jurisdiction, while all other claims continue in arbitration.

13.4 Exceptions. Either party may bring a qualifying claim in small-claims court in lieu of arbitration, provided the claim qualifies under that court's rules. Either party may seek injunctive or other equitable relief in a court of competent jurisdiction with respect to actual or threatened infringement, misappropriation, or violation of intellectual-property rights.

13.5 Right to Opt Out. You may opt out of the arbitration agreement and class-action waiver in this Section 13 by sending written notice to hello@mybest24.com with the subject line "Arbitration Opt-Out" within thirty (30) days of your first acceptance of these Terms. Your notice must include your full name, the email address associated with your account, and a clear statement of your election to opt out. If you opt out, neither party will be bound by the arbitration agreement or class-action waiver, but all other provisions of these Terms continue to apply.

13.6 Federal Arbitration Act. The arbitration agreement in this Section 13 is governed by the Federal Arbitration Act (9 U.S.C. § 1 et seq.).

[LAWYER REVIEW REQUIRED — HIGH PRIORITY] — Widely-litigated consumer-app boilerplate. A licensed attorney must confirm: (i) AAA versus JAMS choice; (ii) opt-out address and procedure; (iii) any California-specific carve-outs (e.g., PAGA enforceability post-Viking River); (iv) mass-arbitration protections.

14. Governing Law and Venue

These Terms are governed by the laws of the State of California, excluding its conflict-of-laws principles. For any dispute not subject to arbitration under Section 13, exclusive jurisdiction and venue lie in the state and federal courts located in Los Angeles County, California, and you consent to the personal jurisdiction of those courts.

[LAWYER REVIEW REQUIRED] — Confirm county and venue language.

15. Termination

15.1 By You. You may discontinue use of the Service and delete your account at any time. To delete your account, contact hello@mybest24.com. If you have an active MyBest24 Pro subscription at the time you request deletion, your subscription is automatically canceled at the end of the then-current billing period in accordance with Section 9.6; no further charges are made.

15.2 By Us. We may suspend or terminate your account if you violate these Terms, if your activity creates risk or potential legal exposure for MyBest24, or for an extended period of inactivity. We will provide notice where reasonable.

15.3 Effect. Upon termination, your right to access the Service ceases. Your data is removed in accordance with the schedule set forth in our Privacy Policy.

15.4 Survival. The following Sections survive termination of these Terms: 7 (Your Content, license to retain backups), 8 (Our Content), 9.7 (Refunds), 9.14 (Disputes Concerning Charges), 10 (Disclaimer of Warranties), 11 (Limitation of Liability), 12 (Indemnification), 13 (Dispute Resolution), 14 (Governing Law and Venue), and any other provision that by its nature should survive.

16. Modifications to These Terms

We may update these Terms from time to time. When we do, we will update the "Effective Date" at the top of this document. For material changes, we will provide notice within the Service or by email to the address associated with your account at least fourteen (14) days before the changes take effect, where reasonable. Your continued use of the Service after the effective date of material changes constitutes acceptance of the updated Terms. If you do not agree, your remedy is to discontinue use and delete your account.

17. Miscellaneous

17.1 Entire Agreement. These Terms, together with the Privacy Policy and any feature-specific notices presented within the Service, constitute the entire agreement between you and MyBest24 regarding the Service and supersede all prior agreements.

17.2 Severability. If any provision of these Terms is held unenforceable, the remaining provisions remain in full force and effect, and the unenforceable provision will be reformed only to the extent necessary to make it enforceable.

17.3 No Waiver. Our failure to enforce any provision is not a waiver of our right to do so subsequently.

17.4 Assignment. You may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, sale of assets, or by operation of law.

17.5 Notices to You. We may send notices to the email address associated with your account, post them within the Service, or both.

17.6 Notices to Us. Notices to us should be sent to hello@mybest24.com. Where these Terms require written notice, email is sufficient unless we specify otherwise.

17.7 Force Majeure. We are not liable for delays or failures caused by events beyond our reasonable control.

17.8 Communications. We may send you two kinds of email: (a) account and transactional communications, including, without limitation, receipts, renewal reminders, billing notices, security alerts, trial-ending notices, and other communications necessary to operate your account or to comply with applicable law; and (b) marketing communications, including product updates, tips, and promotions. You may unsubscribe from marketing communications at any time through the unsubscribe link in any marketing email or through your account settings. You may not unsubscribe from account and transactional communications, which are necessary to operate your account. Where applicable law requires additional opt-out mechanisms, we will comply with that law.

18. Contact

Questions regarding these Terms may be directed to hello@mybest24.com.
