Terms of Service
Effective date: July 5, 2026
1. Agreement to these Terms
These Terms of Service (“Terms”) are a legal agreement between you and Aiden August Lindan Buck (“Byrna,” “we,” “us”) governing your use of the Byrna iOS application and related services (the “Service”). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service. Please also review our Privacy Policy and our Consumer Health Data Privacy Policy, which are incorporated by reference. The Service is intended for users in the United States.
2. Eligibility and age requirements
You must be at least 18 years old to use Byrna. By creating an account or using the Service, you represent and warrant that you are 18 or older. The Service — including its optional social features (handles, handle search, friend requests, friend connections, and shared activity summaries) — is limited to adults, and you must affirmatively confirm that you are at least 18. The Service is not intended for, directed to, or available to anyone under 18.
3. Truthful age information
You must provide truthful and accurate age information. When you create an account, you must give your real date of birth and truthfully confirm that you are at least 18. You may not misrepresent your age to gain access to the Service or any feature.
4. Users under 18
We do not knowingly permit anyone under 18 to create an account or use the Service. If we learn that a user is under 18, we will terminate the account and delete associated information consistent with our Privacy Policy and applicable law. If you believe someone under 18 has created an account, contact us at buckaiden40@gmail.com.
5. Consequences of false age information and misuse
False age representations may result in suspension or termination. If we determine or reasonably believe that you have provided false age information, we may suspend or terminate your account and revoke access, with or without notice.
Misuse may result in account removal. We may suspend, restrict, or terminate your account, and remove content or connections, if you misuse the Service, including: harassing, abusing, threatening, or endangering other users; circumventing safety, eligibility, or age controls; abusing search, friend requests, reporting, or other features; posting objectionable content as described in Section 6; or violating these Terms or applicable law. We take these actions at our discretion to protect users and the integrity of the Service.
6. Acceptable use, objectionable content, and moderation
Byrna’s social features let you choose a handle and share limited activity information with connections you approve. This is user-generated content, and we have zero tolerance for objectionable content and for abusive users.
Prohibited content and conduct. You agree not to create, share, or transmit any content — including in handles, profile information, or shared activity — and not to engage in any conduct, that: is unlawful, harassing, threatening, abusive, defamatory, hateful, sexually explicit, or otherwise objectionable; impersonates another person; sexualizes, exploits, or endangers minors; infringes others’ rights; or violates these Terms or applicable law. You also agree not to access or attempt to access features you are not authorized to use; interfere with or circumvent security, eligibility, or safety controls; or scrape, reverse-engineer, or otherwise misuse the Service.
Filtering. We filter and screen user-generated content (including handles) for objectionable material and may reject, remove, or modify content that violates these Terms.
Reporting and blocking. The Service provides tools to report objectionable content or abusive users and to block other users. Reports can also be sent to buckaiden40@gmail.com.
Our response commitment. We will act on reports of objectionable content or abusive behavior by removing the content and/or ejecting the responsible user within 24 hours of a report where we determine a violation has occurred.
7. Your account
You are responsible for maintaining the security of your Apple sign-in and your account. Byrna uses Sign in with Apple; you are responsible for activity that occurs under your account. Notify us at buckaiden40@gmail.com if you believe your account has been compromised.
8. Your content and data
You retain your rights to the fitness and personal data you create. Most of your data (including your workouts and health entries) is stored on your device and in your own private iCloud account, as described in the Privacy Policy. To the extent you make content available through the social features, you grant us a limited, non-exclusive license to host, store, and display that content solely to operate and provide the Service.
9. Subscriptions and payment
Byrna offers auto-renewing paid subscriptions billed through Apple’s in-app purchase system.
Before you subscribe, we present the subscription’s price, billing period, and the fact that it renews automatically. By subscribing, you consent to these automatic-renewal terms. Your subscription renews automatically at the end of each billing period at the then-current price, and your Apple account is charged, unless you cancel at least 24 hours before the end of the current period. You can cancel at any time through your Apple account settings (Settings → your name → Subscriptions), and cancellation is at least as easy as signing up. Cancellation takes effect at the end of the current period; we do not provide refunds for partial periods except where required by law. These auto-renewal terms are also disclosed on the purchase screen at the point of sale.
10. AI features and generated content
The Service uses artificial intelligence to generate fitness, workout, and self-improvement suggestions and other content. AI-generated output may be inaccurate, incomplete, or unsuitable for you, and is not personalized medical, health, nutritional, or professional advice. Do not rely on it as a substitute for a qualified professional. You are responsible for evaluating AI-generated suggestions before acting on them, and you use them at your own risk. Always consult a qualified professional before beginning or changing any exercise or nutrition program. As described in the Privacy Policy, using an AI feature transmits the inputs it needs to our AI provider to generate a response.
11. Service changes and availability
We may modify, suspend, or discontinue features of the Service at any time.
12. Disclaimers — health, fitness, and AI
Byrna provides general fitness and self-improvement tools and is not medical advice. The Service, including any AI-generated content (Section 10), is provided for general informational purposes only. Consult a qualified professional before beginning any exercise or nutrition program. You assume the risks of any physical activity you choose to undertake.
13. Disclaimers of warranty, limitation of liability, and indemnification
Warranty disclaimer. THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that the Service will be uninterrupted or error-free, or that any AI-generated content is accurate or suitable for you.
Limitation of liability. TO THE MAXIMUM EXTENT PERMITTED BY LAW, Aiden August Lindan Buck WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM OR USD $100. Nothing in these Terms limits liability that cannot be limited under applicable law, including liability for gross negligence, willful misconduct, or fraud.
Indemnification. You agree to indemnify and hold harmless Aiden August Lindan Buck from any claims, damages, losses, and expenses (including reasonable legal fees) arising from your content, your conduct, your use of the Service, or your violation of these Terms or applicable law.
14. Governing law and dispute resolution
Governing law. These Terms are governed by the laws of the State of Hawaii, USA, without regard to its conflict-of-laws rules, except where your local consumer-protection or privacy law grants you rights that cannot be waived (for example, the rights of California or Washington residents).
Informal resolution first. Before filing any claim, you agree to contact us at buckaiden40@gmail.com and attempt to resolve the dispute informally for at least 60 days.
Arbitration and class waiver. If we cannot resolve a dispute informally, you and we agree to resolve it through binding individual arbitration rather than in court, except that either party may bring a qualifying claim in small-claims court. You and we waive the right to a jury trial and to participate in a class action.
Opt-out. You may opt out of this arbitration agreement by emailing buckaiden40@gmail.com within 30 days of first accepting these Terms; opting out does not affect the other provisions.
15. Apple and third-party terms
These Terms are between you and Aiden August Lindan Buck only, not with Apple. Apple’s standard Licensed Application End User License Agreement applies to your use of the app, and these Terms supplement it; where they conflict on a matter Apple’s EULA addresses, Apple’s EULA controls. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them. Apple has no obligation to furnish maintenance or support for the app and is not responsible for the app or any claims relating to it. 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 prohibited-party list.
16. Termination
You may stop using the Service and delete your account at any time from within the app. We may suspend or terminate your access as described in Sections 5 and 6 or as otherwise permitted by these Terms.
17. General terms
These Terms are the entire agreement between you and us regarding the Service and supersede prior agreements. If any provision is found unenforceable, the remaining provisions stay in effect. Our failure to enforce any provision is not a waiver of it. You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of assets. We are not liable for delays or failures caused by events beyond our reasonable control. Notices to you may be provided in the app or by email associated with your account; because Sign in with Apple users may use a private relay email, we may also provide notice in-app.
18. Changes to these Terms
We may update these Terms from time to time and will post the updated version with a new effective date. For material changes, we will provide notice in-app and, where appropriate, request your acceptance before you continue using the Service.
