Terms of Service
Effective date: July 25, 2026
Welcome to Klyva. These Terms of Service ("Terms") are a legal agreement between you and Legend Business Limited Liability Company ("Klyva," "we," "us"), concerning your use of the Klyva app and the klyva.app website. By downloading or using Klyva, you confirm that you have read, understood, and agree to these Terms. If you don't agree, please don't use Klyva.
Who can use Klyva
You must be at least 18 years old to use Klyva on your own. If you are between 13 and 17, you may use Klyva only with the permission and supervision of a parent or guardian who agrees to these Terms on your behalf. Klyva is not intended for anyone under 13.
What Klyva is
Klyva is an informational tool that scans cosmetic and personal-care products and provides ingredient-based scores and explanations, based on public scientific and regulatory sources. Klyva is designed to help you become more aware of what's in the products you use — it does not tell you whether to buy or avoid any product.
How scores work — and what they mean
A Klyva score is an opinion generated by our algorithm, based on an analysis of a product's ingredients using published scientific and regulatory sources. Please understand:
- We assess ingredients, not brands. A score is not a judgment of a company, a manufacturer, or a product's overall quality, effectiveness, or commercial value.
- A low score does not mean a product is unsafe, harmful, or unfit for use, and a high score is not a guarantee of safety or results. The words and ratings Klyva uses refer only to our ingredient-based opinion.
- Scores reflect which ingredients are present, not their concentrations. We generally cannot know the exact amount of each ingredient in a product.
- Klyva only assesses ingredients it recognizes, and is transparent when it can't confidently score a product.
Not medical advice
Klyva does not provide medical advice. Our scores and information are general, informational guidance — not a diagnosis, treatment, or professional recommendation, and are no substitute for a consultation with a qualified dermatologist, doctor, or other healthcare professional. Never disregard or delay professional advice because of something you read in Klyva. Always patch-test new products and follow product instructions. You use Klyva's information at your own risk and discretion.
Accuracy, and your responsibility to check the label
We work hard to be accurate and to cite our sources, but product and ingredient data comes from public sources (including Open Beauty Facts), from brands, and from label reading, all of which can contain errors or be incomplete, and automatic text recognition (OCR) can misread a label. We do not guarantee the accuracy or completeness of ingredient data or scores, which are provided "as is." It is your responsibility to check the ingredients directly on the product's packaging to confirm its actual composition before you rely on it.
Allergies and sensitivities
Klyva's "ingredients to avoid" and personalization features are a convenience, not a safety guarantee. If you have a severe allergy or any condition that could cause a serious reaction, do not rely on Klyva. Because ingredient data can be incomplete or out of date, always read the full ingredient list on the product packaging yourself, and consult a healthcare professional about ingredients you must avoid.
Independence
Klyva is independent. We do not display advertising, no brand or company can pay us to influence a score or to be featured, and we do not sell your data. Klyva is funded by optional Klyva Premium subscriptions.
Subscriptions and billing
Klyva offers a free tier and an optional Klyva Premium subscription.
- Subscriptions are billed through Apple or Google using your app-store account, and those stores' terms also apply to your purchase and prevail over these Terms in the event of a conflict about billing.
- Plans, prices, and any free-trial terms are shown in the app before you purchase. A subscription renews automatically unless you cancel at least 24 hours before the end of the current period.
- You manage or cancel your subscription in your device's app-store settings (Apple ID or Google Play), not within Klyva. Deleting the app does not cancel a subscription.
- Free scanning and the general score remain available without a subscription.
Your contributions
When you confirm and submit a product's ingredient list, you agree to provide truthful information taken directly from the product packaging, and you grant us a non-exclusive, worldwide, royalty-free license to store and use that ingredient data (without information identifying you) to operate and improve Klyva's shared product database for all users.
Acceptable use
You agree not to misuse Klyva. In particular, you agree not to: use it for any unlawful purpose; disrupt, probe, or test its security or infrastructure; introduce malware; scrape or harvest its data or content by automated means; reverse-engineer, decompile, or copy it; use it for commercial resale of its scores or data; or submit false, offensive, or unlawful content. We may suspend or terminate accounts that violate these Terms.
Intellectual property
Klyva — its name, logo, design, software, scoring methods, and content — is owned by Legend Business Limited Liability Company. We grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the app. You may not copy, resell, or create derivative works from it without our permission. All rights not expressly granted are reserved.
Disclaimer of warranties
Klyva is provided "as is" and "as available," without warranties of any kind, express or implied, to the fullest extent permitted by law. We do not warrant that the app will be uninterrupted, error-free, or compatible with every device.
Limitation of liability
To the maximum extent permitted by law, Klyva and Legend Business Limited Liability Company will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any decisions you make based on the information in the app. Our total liability for any claim relating to the app will not exceed the amount you paid us in the 12 months before the claim (or, if you use the free version, US $100). Nothing in these Terms limits liability that cannot be limited by law.
Indemnification
You agree to indemnify and hold harmless Legend Business Limited Liability Company and its officers, employees, and agents from any claims, losses, or expenses (including reasonable legal fees) arising out of your misuse of Klyva or your breach of these Terms.
Termination
We may suspend or terminate your access to Klyva at any time if you violate these Terms. You may stop using Klyva at any time and delete your account from within the app.
Governing law and disputes
These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-laws rules. Before starting any formal legal action, you agree to first contact us at support@klyva.app and attempt in good faith to resolve the dispute informally for a period of 60 days. If the law of your country or state of residence gives you stronger consumer protections, those protections still apply to you.
Changes
We may update these Terms from time to time. We'll post the updated version here with a new effective date. Continued use of Klyva after that means you accept the updated Terms.
Severability
If any part of these Terms is found to be invalid or unenforceable, the rest remains in full effect.
