- Service improvement: Analyze user behavior in aggregated form (non-personally identifiable) to improve interface, performance and content.

All third-party partners selected by hz66 must comply with data security standards equivalent to or higher than those we apply internally. They are not permitted to use your data beyond the scope of services agreed with hz66.
4Data Security
Hz66 applies multiple layers of technical and organizational security to protect your data from unauthorized access, loss, or disclosure. Below are the main measures we implement:
- SSL/TLS encryption: All connections between your device and hz66 servers are encrypted with 256-bit SSL/TLS, ensuring transmitted data cannot be intercepted in transit.
- Data encryption at rest: Sensitive information such as passwords are stored as one-way hash (bcrypt/Argon2). Even hz66 employees cannot read your original password.
- Internal access control: Only employees with genuine business needs have access to user data. All access is logged and audited regularly.
- Two-Factor Authentication (2FA): hz66 supports and encourages users to enable 2FA for an additional layer of account protection beyond your password.
- Intrusion detection: 24/7 activity monitoring system to detect and respond promptly to signs of attack or unusual access.
- Periodic security audits: hz66 conducts regular security assessments and penetration testing to proactively identify and patch potential vulnerabilities.
