Terms of Use

Effective April 3, 2026

These Terms of Use ("Terms") govern your use of the Circa mobile application ("Application") for iOS, developed by Stanislav Perevozchikov ("Developer," "we," "us," or "our"). By downloading, installing, or using the Application, you agree to be bound by these Terms. If you do not agree, do not use the Application.

These Terms supplement the Apple Standard End User License Agreement (EULA). In the event of a conflict between these Terms and the Apple EULA, these Terms shall control with respect to the subject matter covered herein.

Description of Service

The Application is a subscription-based tool that uses artificial intelligence to identify and provide estimated valuations for antiques and collectibles based on photos you submit. The Application also provides a chat feature ("Expert on Call") for general informational discussions about antiques and collectibles.

Subscription and Payment

The Application requires a paid subscription to access its features. Subscriptions are billed through Apple's App Store and are subject to Apple's payment terms. By subscribing, you acknowledge and agree that:

• Subscriptions automatically renew unless canceled at least 24 hours before the end of the current billing period.
• Your Apple ID account will be charged for renewal within 24 hours prior to the end of the current period.
• You may manage and cancel your subscription in your Apple ID account settings.
• Any unused portion of a free trial period, if offered, will be forfeited when you purchase a subscription.

Pricing is subject to change. We will notify you of any price changes in accordance with Apple's policies.

AI-Generated Content Disclaimer

The Application uses artificial intelligence to generate item identifications, valuations, and chat responses. All information provided by the Application is for informational and entertainment purposes only.

You expressly acknowledge and agree that:

• AI outputs are not professional appraisals. The Application does not provide professional appraisals, authentication, or expert opinions. Identifications and valuations are AI-generated estimates that may be inaccurate, incomplete, or wrong.
• No reliance. You should not rely on the Application's output to make purchasing, selling, insurance, or any other financial decisions. You assume all risk associated with any decision made based on information provided by the Application.
• No guarantee of accuracy. AI models can and do produce errors, including misidentification of items, incorrect valuations, fabricated information, and hallucinated details. We make no representation or warranty regarding the accuracy, reliability, or completeness of any AI-generated content.
• Not a substitute for professional advice. If you require a professional appraisal, authentication, or valuation, you should consult a qualified, licensed appraiser or relevant expert.
• Market prices fluctuate. Any pricing information displayed reflects estimates based on publicly available market data at a point in time and may not reflect current market conditions.

You represent and warrant that you have the right to submit any User Content you provide and that your User Content does not infringe the rights of any third party.
