Privacy Policy
Last updated: January 14, 2025
🔒 Privacy First
ChartScope is designed with privacy at its core. We do not collect, store, or transmit your personal data to external servers. All processing happens locally on your device.
Information We Don't Collect
ChartScope is committed to your privacy. We do not collect:
- Personal identification information
- Email addresses or contact details
- Location data
- Usage analytics or tracking data
- Your API keys or credentials
- Your portfolio data or trading history
Local Data Storage
ChartScope stores certain data locally on your device to provide its functionality:
- API Credentials: Your exchange API keys are stored exclusively in the iOS Keychain, which provides hardware-level encryption. These credentials never leave your device.
- User Preferences: Settings like your preferred currency, language, and theme are stored locally using iOS UserDefaults.
- Cached Market Data: Market data fetched from exchanges may be temporarily cached to improve performance.
On-Device Processing
All AI analysis and data processing in ChartScope occurs locally on your device using Apple's Core ML framework. This means:
- Your market data is never sent to external AI servers
- Analysis results are generated entirely on your device
- No internet connection is required for AI features after initial setup
Third-Party Services
ChartScope connects to the following third-party services:
- Cryptocurrency Exchanges: We connect to exchanges (Binance, Coinbase, Kraken) using their public APIs to fetch market data and, with your permission, your portfolio information. These connections use your API keys stored locally and are made directly from your device.
- Apple App Store: For subscription management and in-app purchases, we use Apple's StoreKit framework.
We do not use any third-party analytics, advertising, or tracking services.
Data Security
We implement the following security measures:
- API keys are stored in iOS Keychain with hardware encryption
- All network communications use HTTPS/TLS encryption
- Read-only API permissions are encouraged and enforced where possible
- No sensitive data is ever logged or stored in plain text
Your Rights
Since we don't collect personal data, traditional data rights (access, deletion, portability) are handled entirely on your device. You can:
- Delete all app data by uninstalling ChartScope
- Remove API credentials through the app settings
- Clear cached data through iOS Settings
Children's Privacy
ChartScope is not intended for use by children under 17. We do not knowingly collect any information from children. The app deals with financial markets and is designed for adult users only.
