By downloading or using Patina ("the app"), you agree to these terms. If you don't agree, please don't use the app.
1. What the app does
The app uses AI to identify antique, vintage and collectible objects from photos, including the period and style, likely maker or origin, approximate age, condition notes, whether the piece reads as period or reproduction, care advice and an estimated value range. It also ships an offline reference library of maker's marks, hallmarks and period styles. Identifications, dates and estimates are generated automatically and may be wrong. They are provided for information and education only.
2. Estimates are not appraisals
Value estimates, dating and period-versus-reproduction notes are informational and must never be your only basis for a purchase, sale, insurance or probate decision. Antique prices vary enormously with maker, provenance, condition, originality and the venue of sale, and skilled reproductions routinely pass photo inspection — even in person, experts disagree. For anything of consequence, obtain a written appraisal from a qualified appraiser (for example ASA, ISA or AAA accredited) or a specialist auction house. The reference library is a research aid compiled from published sources and may contain errors or omissions.
3. Subscriptions
Premium features (unlimited scanning and the full object profile including value estimates) require a subscription billed through your Apple account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in Settings → your name → Subscriptions. Refunds are handled by Apple under their terms. Where required, Apple's standard licensed application terms apply: Apple Standard EULA.
4. Acceptable use
You agree not to abuse the service — including automated scraping, reverse-engineering the app or its API, circumventing usage limits or subscription checks, or using the app for anything unlawful. You are responsible for complying with the law where you buy and sell, including rules on cultural property, protected materials such as ivory and tortoiseshell, firearms and militaria, and the accurate description of goods you offer for sale. Do not represent an app estimate as a professional appraisal.
5. Third-party services
The app relies on third-party services to work: AI processing (OpenAI), subscription management (RevenueCat) and payments (Apple). Their availability is outside our control; the app's features may be limited if a provider is unavailable. Reference photographs are used under free licences and credited in the app's Photo credits screen.
6. No warranty, limitation of liability
The app is provided "as is", without warranties of any kind. To the maximum extent permitted by law, we are not liable for any indirect, incidental or consequential damages, or for losses arising from decisions made based on identifications, dating, value estimates or authenticity notes. Our total liability is limited to the amount you paid for the app in the last 12 months.
7. Changes and termination
We may update the app, these terms, or discontinue the service. Material changes to these terms will be reflected by the effective date above. We may suspend access in cases of abuse (section 4).
