Intrinsix — Terms of Use

Effective date: 4 July 2026

By downloading or using Intrinsix (“the app”), you agree to these Terms. If you do not agree, do not use the app.

1. What Intrinsix is (and is not)

Intrinsix is a decision-support calculator. It estimates the intrinsic (melt and stone) value of a jewellery lot and a maximum rational bid based on the figures you enter and live metal prices. Its outputs are estimates, not a certified appraisal, and not financial, investment, or purchasing advice. You are solely responsible for your bids, purchases, and any resulting outcomes. Always verify independently before bidding.

2. No affiliation with auction platforms

Intrinsix is an independent tool. It is not affiliated with, endorsed by, or sponsored by Catawiki, eBay, Etsy, or any other auction platform, marketplace, laboratory, or price provider. All product names, logos, and trademarks are the property of their respective owners and are used only to describe compatibility. You are responsible for complying with the terms of any third-party platform you use.

3. Accuracy of data

Metal spot prices, currency rates, and any specifications extracted from a listing come from third-party sources and your own inputs. They may be inaccurate, delayed, or incomplete. Intrinsix does not guarantee the accuracy of any figure and is not liable for decisions made in reliance on them.

4. Subscriptions (Intrinsix Pro)

Your first AI lot analysis is free. Continued AI import requires Intrinsix Pro, an auto-renewing subscription billed through your Apple ID. The subscription renews automatically at the price and period shown at purchase unless cancelled at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before the period ends. Manage or cancel anytime in your App Store account settings. Prices may change with notice as permitted by the App Store. Purchases are also governed by Apple’s Standard End User License Agreement.

5. Acceptable use

Use Intrinsix only for lawful, personal purposes. Do not attempt to circumvent the free-use metering, reverse-engineer the service, or misuse it to disrupt third-party platforms.

6. Intellectual property

The app, its design, and its valuation engine are owned by the developer. These Terms grant you a personal, non-exclusive, non-transferable licence to use the app.

7. Disclaimer of warranties

The app is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose and accuracy of results.

8. Limitation of liability

To the fullest extent permitted by law, the developer is not liable for any indirect, incidental, or consequential damages, or for any losses arising from bids, purchases, or reliance on the app’s estimates. Nothing in these Terms limits liability that cannot be limited under applicable law.

9. Governing law

These Terms are governed by the laws of Spain, without prejudice to any mandatory consumer-protection rights you have in your country of residence.

10. Changes

We may update these Terms; continued use after an update constitutes acceptance. The effective date above reflects the latest version.
