About these terms
DPC Rapaport Price (“we”, “our”) is the service name for our website and the Diamond Price Checker app. These terms govern use of the software. By using it, you agree to these terms; if you disagree, do not use the service.
What the software provides
We provide reference diamond-price calculations using carat weight, shape, colour, clarity and a percentage adjustment. Round uses the Round reference; every other supported shape uses Pear as a reference. Estimates are informational, not a purchase offer, guaranteed sale price, valuation certificate or financial, legal or professional gemological advice.
Licence and accounts
You receive a limited, non-exclusive, non-transferable licence to use the software for its intended purpose, subject to applicable platform rules. Keep account details accurate and credentials secure. Do not share credentials, bypass access controls, disrupt the service, redistribute protected data or reverse-engineer the software except where applicable law permits.
Website access and app purchases
The website provides two successful free calculations per account, then directs you to our app. Deleting a saved result or signing in again does not reset this allowance. Website account access does not itself provide app Pro access. In-app subscriptions are billed through Apple; price, duration and any trial are shown before purchase. Subscriptions renew automatically unless cancelled under the purchase terms. Manage or cancel them in your Apple Account subscription settings.
Intellectual property
Our software, design and original content belong to DPC Rapaport Price or the respective rights holders. Third-party names, price data and trademarks remain their owners’ property. A software subscription does not grant redistribution rights in third-party material. Rapaport references identify the pricing methodology and do not imply endorsement or affiliation.
Availability and responsibility
Prices depend on the available source and its date. Features or availability may change. Check the individual stone and its grading report before acting on an estimate. To the extent permitted by law, the service is provided as available without guarantees of uninterrupted operation, and we are not responsible for indirect or consequential losses. No mandatory consumer rights or non-excludable liability are limited.
Deletion, updates and contact
You can delete your account in the app. Deleting an account does not cancel an Apple subscription. Data handling is explained in our Privacy Policy. We may update these terms and identify the effective date; material changes will be communicated through the service where appropriate. For questions, use Contact Us on this website.
