Crypto Ledger Advanced Usage Privacy Policy describes how personal data is collected, processed, stored, and protected when users interact with Crypto Ledger applications, hardware devices, websites, and advanced feature documentation. This policy applies to all platforms where Crypto Ledger services operate, including desktop applications, mobile applications, and web properties providing advanced usage documentation.

This Privacy Policy was last updated in January 2026. Periodic review is recommended as updates may occur reflecting changes in data handling practices, regulatory requirements, or service capabilities. Continued use of Crypto Ledger services after policy updates constitutes acceptance of revised terms.

Data Collection

Crypto Ledger Advanced Usage services collect limited categories of personal data necessary for providing wallet functionality and advanced feature support.

Device and configuration data includes hardware wallet model identifiers, firmware versions, installed applications, account structures, and feature configuration states. This data enables correct interface display, compatible update delivery, and advanced feature operation. No personally identifiable information is required to use Crypto Ledger advanced features.

Advanced feature telemetry encompasses anonymized information about passphrase usage rates (not passphrase content), derivation path selections, DeFi connection patterns, and multi-account structures. This data supports feature improvement and identification of configuration issues. Telemetry collection is optional and can be disabled in application settings.

Support interaction data includes information provided when submitting advanced technical inquiries or communicating with support staff regarding complex configurations. This data is necessary to provide accurate guidance for sophisticated use cases.

Website visitor data comprises standard server logs including IP addresses, browser types, pages visited, and timestamps. This data supports security monitoring and documentation improvement.

Cookies and Tracking Technologies

Crypto Ledger websites use cookies and similar technologies for functionality and analysis.

Essential cookies enable core website functions including navigation, session management, and security features. These cookies are necessary for proper website operation and cannot be disabled without affecting functionality.

Analytics cookies collect anonymized website usage data including documentation pages visited, feature interest patterns, and navigation sequences. These cookies support content improvement and can be disabled through the consent interface.

Preference cookies remember advanced user settings, documentation viewing history, and configuration preferences. These cookies improve the user experience and can be managed through browser settings.

Cookie preferences can be managed through settings links in website footers. Browser configuration can also control cookie acceptance, though this may affect functionality.

Analytics and Performance Monitoring

Crypto Ledger Advanced Usage uses analytics to understand how users interact with advanced features and documentation. Analytics data undergoes aggregated processing and specifically excludes private keys, recovery phrases, passphrases, account balances, transaction details, and personally identifying information.

Feature usage analytics track anonymous patterns of advanced feature adoption to identify documentation needs and interface improvements. This data helps prioritize development without identifying individual users.

Application analytics operate through opt-in telemetry collecting anonymized events such as feature configuration changes, error conditions, and performance metrics. Users declining analytics transmit no telemetry data.

Documentation analytics measure anonymous engagement with advanced feature guides to identify areas requiring clarification or expansion.

Analytics data retention follows a 26-month rolling period. After this window, aggregated trend data is archived while raw event data is permanently deleted.

Third-Party Tools and Services

Crypto Ledger Advanced Usage integrates with third-party services for specific functions. Data shared with these services is governed by their respective privacy policies.

DeFi protocol connections transmit transaction data to decentralized applications when users interact through Ledger Connect or WalletConnect. These connections are user-initiated and data handling depends on specific protocol policies.

Blockchain network nodes receive transaction data when users execute operations. This data is inherently public on blockchain networks and is required for transaction processing.

Genuine check services verify hardware wallet authenticity. This verification confirms device integrity without transmitting private keys, recovery phrases, or passphrases.

Cloud infrastructure providers host backend services under data processing agreements requiring compliance with applicable data protection regulations.

Analytics platforms process anonymized usage data to provide insights about feature adoption and application performance without identifying individual users.

Data Security

Crypto Ledger Advanced Usage implements comprehensive technical and organizational security measures:

We never ask for your recovery phrase or private keys. The Crypto Ledger architecture ensures recovery phrases, passphrases, and private keys exist only inside hardware wallet secure elements. These cryptographic secrets are never transmitted to Ledger servers, companion applications, or third parties. Advanced users should recognize that sophisticated phishing attempts may reference technical features to appear legitimate. Any request for recovery phrases or passphrases should be immediately recognized as fraudulent.

Data Retention

Crypto Ledger Advanced Usage retains personal data only for durations necessary to fulfill stated purposes:

Advanced feature configurations (passphrases, derivation paths, account structures) are stored only on local devices and hardware wallets, never on Ledger servers.

Users can request data deletion subject to legal retention requirements. Deletion requests can be submitted through the support portal with identity verification as required.

User Rights

Depending on jurisdiction, users may exercise rights regarding personal data including:

Rights requests can be submitted through the support portal at support.ledger.com. Identity verification may be required before processing to prevent unauthorized access. Responses are provided within 30 days or within timeframes required by applicable law.

International Transfers

Data may be transferred internationally for processing by service providers and infrastructure partners located outside the user jurisdiction. Such transfers are protected by appropriate safeguards including Standard Contractual Clauses approved by relevant regulatory authorities, adequacy decisions recognizing equivalent data protection standards, and binding corporate rules where applicable.

Children Privacy

Crypto Ledger services are not directed at individuals under 18 years of age. Personal data from minors is not knowingly collected during advanced feature usage. If such collection is discovered, the data will be deleted promptly upon notification.

Policy Changes

This policy may be updated to reflect changes in data handling practices, regulatory requirements, or service capabilities. Material changes will be communicated through application interfaces, website notices, or direct communication where appropriate.
