Terms of Use
Estimates, not appraisals. Everything Carat tells you about a piece — what it is, whether it is genuine, what it is worth, how a stone grades — is an estimate produced by an AI model from a photograph. It is not a certified appraisal, not a laboratory grading report, and not advice for insurance, sale, purchase, tax, probate or legal purposes. Carat’s results are not professional appraisals; for any of those purposes, have the piece examined by a qualified appraiser or gemologist.
1. The service
Carat: Jewelry & Diamond ID (“Carat”) identifies jewellery and gemstones from photographs and estimates their value using an AI model and web search over recent sales. Results depend on your photographs and on public information and may be wrong or incomplete. Carat does not physically test stones or metals.
2. Eligibility
You must be at least 13 years old, or the age of digital consent where you live, and able to enter a binding contract.
3. Subscriptions and purchases
Carat requires an active subscription or a lifetime purchase to identify pieces. Reference prices in the United States are USD 49.99 per year, USD 5.99 per week, and a one-time USD 79.99 for lifetime access; prices vary by country and are shown in the app before you buy. Payment is charged to your Apple ID at confirmation of purchase.
Automatic renewal. Subscriptions renew automatically at the same price and period unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple ID account settings. Deleting the app does not cancel a subscription.
Free trial. The annual plan starts with a 7-day free trial for new subscribers. Unless you cancel before the trial ends, the annual price is charged when it ends. Any unused portion of a free trial is forfeited when you purchase a subscription.
Lifetime purchase is a one-time, non-consumable purchase tied to your Apple ID that grants access for the life of the app.
4. Refunds
Purchases are made through Apple. Refunds are handled by Apple under its terms; we cannot issue them directly. Where the law gives you a right of withdrawal, you consent to immediate delivery of the digital service and acknowledge that the right is lost once identification begins.
5. Acceptable use
You may use Carat for your own research and curiosity. You may not: upload photographs you have no right to use; attempt to extract the model, prompts or data behind the service; use automated tools against the service; use results to misrepresent a piece to a buyer, insurer or authority; or present Carat’s output as a professional appraisal.
6. Your content
You keep the rights to your photographs and notes. You grant us a licence to process them to provide the service and, in anonymised form, to improve the identification quality. Delete a piece to withdraw the licence for that piece.
7. Our content
Carat, its name, mark, design, text and software are owned by Yaysoft LTD or its licensors. Nothing in these terms gives you a right to use them except as needed to use the app.
8. Availability
We aim for continuous service but do not guarantee it. We may change or withdraw features, and we may suspend the service for maintenance or to protect it from abuse.
9. No warranty
The service is provided “as is”. To the fullest extent permitted by law we disclaim all warranties, including accuracy of identification, authenticity verdicts, grades and values.
10. Limitation of liability
To the fullest extent permitted by law, Yaysoft LTD is not liable for any loss arising from reliance on a result, including a purchase, sale, insurance decision or valuation. Our total liability for any claim is limited to the amount you paid us in the twelve months before the claim. Nothing limits liability for death or personal injury caused by negligence, for fraud, or for any right you have under consumer law that cannot be limited.
11. Termination
You may stop using Carat at any time. We may suspend or end your access if you breach these terms. Sections 6–12 survive termination.
12. Governing law
These terms are governed by the laws of England and Wales. Consumers keep any mandatory protections of the law where they live, and may bring claims in their local courts.
13. Changes
We may update these terms; the date above changes when we do. Continued use after a change means you accept it. Material changes are announced in the app.
14. Contact
Apple’s standard Licensed Application End User License Agreement also applies to the app as distributed through the App Store.
