This Privacy Policy describes how CoinProbe ("we", "us", or "our") collects, uses, and protects information when you use the CoinProbe mobile application (the "App") and related services.
By using the App, you agree to the collection and use of information as described in this policy. If you do not agree, please do not use the App.
## 1. Who we are
CoinProbe is a mobile app that helps users photograph coins and banknotes, receive identification results, save scan history, and chat with an AI-powered numismatic assistant.
For privacy-related questions, contact us at:
Email: [email protected]
## 2. Information we collect
We collect only the information needed to operate the App and improve your experience.
### 2.1 Information you provide
- Photos you capture with the camera or select from your photo library for scanning and identification
- Messages and optional images you send in the expert chat feature
- Coins or banknotes you save to your collection, favorites, and scan history within the App
- Support requests or other communications you send to us
### 2.2 Information collected automatically
- Basic device and app information, such as operating system version, app version, and general usage events needed to keep the App working
- Subscription and purchase status processed through Apple and our subscription provider, RevenueCat, when you subscribe to Pro features
We do not require you to create an account with a username or password to use the App.
### 2.3 Information we do not collect
We do not intentionally collect:
- Precise location data
- Contacts, calendars, or unrelated personal files
- Government ID numbers or payment card numbers directly (payments are handled by Apple)
## 3. How we use your information
We use information for the following purposes:
- To identify coins and banknotes from images you submit
- To display scan results, estimated values, and chat responses
- To store your scan history, saved items, favorites, and chat threads on your device
- To enforce free scan limits and provide Pro subscription features
- To process subscriptions, restore purchases, and manage billing through Apple and RevenueCat
- To maintain, secure, and improve the App
- To respond to support requests and legal obligations
We do not sell your personal information.
We do not use your photos for advertising profiling.
## 4. AI and image processing
When you scan an item or use expert chat with an image, the App may send your image and related request data to our backend servers for processing. Our backend may use third-party AI services to generate identification results and chat replies.
Important points:
- Images are transmitted securely over encrypted connections (HTTPS)
- Processing is limited to providing the features you request
- We do not use your images to train public AI models unless we clearly tell you otherwise and obtain your consent
Identification results are generated automatically and may be incomplete or incorrect. They are provided for informational purposes only.
## 5. Where your data is stored
### 5.1 On your device
Most App data is stored locally on your device, including:
- Scan history and associated photo file references
- Saved collection and favorites
- Chat threads and messages
You can remove this data by deleting individual scans or clearing history within the App, or by uninstalling the App.
### 5.2 On our servers
When you use scanning or chat features, image and text data may be processed on servers operated by us or our hosting providers. We retain server-side processing data only as long as needed to provide the service, troubleshoot issues, and meet legal requirements.
## 6. Third-party services
We rely on trusted third parties to operate parts of the App. These providers may process information according to their own privacy policies:
- Apple App Store and Apple ID for app distribution, in-app purchases, and subscriptions
- RevenueCat for subscription management and purchase restoration
- Cloud hosting providers (such as Vercel) for API infrastructure
- AI service providers used to analyze images and generate chat responses
We encourage you to review the privacy policies of Apple and other third parties that process payments or provide platform services on your device.
## 7. Permissions
The App may request the following device permissions:
- Camera: to capture photos of coins and banknotes
- Photo library: to select existing photos for scanning and, where applicable, to attach images in chat
You can change or revoke permissions in your device settings. Some features will not work without the required permissions.
## 8. Data retention
We keep information only for as long as necessary for the purposes described in this policy:
- Local App data remains on your device until you delete it or uninstall the App
- Server processing data is retained for a limited period needed for operations, security, and legal compliance
- Subscription records are retained as required by Apple, RevenueCat, and applicable tax or accounting rules
## 9. Your choices and rights
Depending on your location, you may have rights to:
- Access information we hold about you
- Request correction or deletion of certain information
- Object to or restrict certain processing
- Withdraw consent where processing is based on consent
- Lodge a complaint with a data protection authority
Because much of your data is stored locally on your device, you can delete scans, chat history, and saved items directly in the App. For other requests, contact us at [email protected].
We will respond to valid requests within a reasonable time and as required by applicable law.
## 10. Children’s privacy
The App is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we will take appropriate steps to delete it.
## 11. International users
If you use the App from outside the country where our servers are located, your information may be transferred to and processed in other countries that may have different data protection laws. Where required, we use appropriate safeguards for such transfers.
## 12. Security
We use reasonable technical and organizational measures to protect information, including encryption in transit and access controls on our systems. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
## 13. Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this document. If changes are material, we may provide additional notice in the App or by other reasonable means.
Your continued use of the App after an update means you accept the revised policy.
