Patinio Privacy Policy
Last updated: 25 October 2026
What we process
Object photos. When you ask for an appraisal, up to four photos of the object are sent over an encrypted connection to our server and analysed by an AI model from OpenAI. Before the first appraisal the app asks for your agreement. Location and other metadata are removed first. We keep the photos for up to 90 days to check and improve the estimates, then they are deleted automatically. Please photograph the object, not people, documents or anything that shows where you live.
What you choose in the app. With the photos the app sends the country you sell in (from your device region, or the one you picked in Settings) and, if you pick one, the kind of object (for example porcelain or silver). It sends no name, address or account.
Device identifier. The app creates a random identifier and stores it in the device keychain (it can survive reinstalling the app). It connects your appraisals, problem reports and daily usage data, applies the daily appraisal limit and lets us count active devices. It is not your name, e-mail, Apple Account or advertising identifier.
Appraisal results. For each appraisal we keep the AI answer (what the object is, marks read, condition, price ranges, notes), processing time and any error, with the device identifier, for up to 90 days.
Usage data. Once a day the app sends app version, region, language and whether a subscription is active. When the subscription screen is shown, the app records that it was shown and whether a purchase was started, completed or cancelled (with the plan and region). We use this to count users and improve the app; it is deleted 90 days after you last used the app.
Problem reports. If you report a wrong result, we receive the reason, your optional comment, the AI answer, the appraisal identifier and, if you switch it on, the first photo. Reports are kept for up to 90 days.
Support e-mails. If you contact support, we receive your e-mail address and message. The app pre-fills technical details (device identifier, recent appraisal identifiers, app and iOS version) that you can edit before sending. We keep support e-mails as long as needed to answer them.
Your history and collection. Your appraisals, your collection and their photos are also stored on your device. Exports (PDF, spreadsheet) are created on your device and only go where you send them.
Purchases. Subscriptions are processed by Apple. We do not receive your payment details. During a free trial, each appraisal is sent with the trial's identifier from the App Store (its original transaction identifier), so that our server can count the appraisals of the trial once over all your devices; the app also sends it when it checks how many trial appraisals are left. We keep this count for 90 days. From Apple our server receives a notice of each subscription event (trial started, renewal, change of plan, cancellation, refund) with the transaction identifiers, the plan, the price and currency and the App Store country; it contains no name, e-mail address or Apple Account, and we keep it for 90 days (a record of a refund or revocation until shortly after the refunded subscription period would have ended).
Who can see it
The developer can look at photos, appraisal results and reports to check quality and answer support requests; access is password-protected. Photos are processed by OpenAI on our behalf. Our server is run by a hosting provider; the AI step runs on a computer operated by the developer, which fetches each photo from our server over an encrypted connection and does not keep it.
What we do not do
No account, no advertising, no tracking across apps or websites, no sale of data. We do not sell or list your objects anywhere; the selling channels shown are links you may follow yourself.
Your choices
Settings → Clear history deletes the appraisal history on your phone (objects in your collection stay). Removing the app deletes the data on your phone except the keychain identifier. Data on our server is deleted automatically after the periods above; to have it deleted earlier, write to us and include the device identifier from a support e-mail.
About the estimates
Patinio's prices are indicative ranges made by AI from your photos and public market information. They are not an official valuation and do not replace the opinion of an auction house or a specialist.
