# Privacy Measures
This document outlines the privacy protection measures implemented in Anya Core.
## Overview
Anya Core implements comprehensive privacy protection measures to ensure user data security and transaction privacy while maintaining Bitcoin protocol compliance.
## Privacy Features
### 1. Transaction Privacy
- **Confidential Transactions**: Implementation of privacy-preserving transaction protocols
- **Address Management**: HD wallet support for enhanced address privacy
- **UTXO Privacy**: Advanced UTXO management for transaction unlinkability
### 2. Data Protection
- **Local Storage**: All sensitive data stored locally with encryption
- **No Data Collection**: No user data transmitted to external servers
- **Secure Communication**: End-to-end encryption for all network communications
### 3. Network Privacy
- **Tor Support**: Built-in Tor integration for network-level privacy
- **Peer Discovery**: Privacy-preserving peer discovery mechanisms
- **Traffic Analysis Resistance**: Measures to prevent traffic correlation attacks
## Implementation Details
### Cryptographic Primitives
- **Encryption Algorithms**: AES-256-GCM for symmetric encryption
- **Key Derivation**: PBKDF2 and scrypt for key derivation
- **Digital Signatures**: Schnorr signatures for enhanced privacy
### Privacy-Preserving Protocols
- **CoinJoin**: Implementation of collaborative transaction protocols
- **Stealth Addresses**: Support for stealth address protocols
- **Ring Signatures**: Research and development of ring signature implementations
## Best Practices
### For Users
1. **Address Reuse**: Always use new addresses for each transaction
2. **Network Configuration**: Use Tor for enhanced network privacy
3. **Local Storage**: Keep wallet files encrypted and secure
### For Developers
1. **Data Minimization**: Collect only necessary data
2. **Secure Coding**: Follow secure coding practices
3. **Privacy by Design**: Implement privacy considerations from the start
## Compliance
- **GDPR Compliance**: Adherence to European privacy regulations
- **Data Protection Laws**: Compliance with relevant data protection legislation
- **Industry Standards**: Following cryptocurrency privacy best practices
