Privacy Policy

Last updated: March 2026


1. Who we are

925s.ai is an AI-powered silverware appraisal service. We help collectors, sellers, and enthusiasts identify and value antique silverware using hallmark recognition and real auction data. Our website is https://925s.ai and you can reach us at contact@925s.ai.

2. What data we collect

Account data: When you create an account (email/password or Google sign-in), we collect your name and email address.

Uploaded images: Photos you upload for appraisal are processed to generate your report. Images are not shared with third parties beyond the AI services needed to analyse them (see section 4).

Appraisal data: The results of your appraisals — hallmark identifications, valuations, and comparable sales — are stored in your account history.

Payment data: Payments are processed entirely by Stripe. We do not store or see your card number. We only receive confirmation of payment completion.

Analytics data: With your consent, we collect anonymised usage data (pages visited, session duration, feature usage) via Google Analytics and PostHog. This data contains no personally identifiable information.

3. How we use your data

  • To provide the appraisal service
  • To send transactional emails (account confirmation, appraisal results)
