Data security is Kualian's core commitment. Here are 6 points explaining our security mechanism:

1. Local Optimization: All network optimization operations are performed locally on your device. Data path optimization does not pass through any third-party intermediary servers, fundamentally eliminating the risk of data interception.
2. Zero-Log Policy: We strictly adhere to a zero-log principle. We do not collect, store, or disclose any personal information or browsing activity records. We have no knowledge of which websites you visit or which applications you use.
3. End-to-End Encryption: During network transmission, Kualian employs industry-leading encryption protocols to protect your data, ensuring that your communication content cannot be intercepted or tampered with during transit.
4. Transparent Privacy Policy: Our privacy policy is written in clear, straightforward language, explicitly outlining data handling practices without any hidden clauses or ambiguous wording. The latest version is always available on our website.
5. No Third-Party Involvement: Kualian does not share, sell, or provide any user data to third-party organizations. All data processing occurs within a strict security framework, with users retaining full control over their data.
6. Regular Security Audits: We regularly commission independent security firms to conduct comprehensive security audits and vulnerability assessments. Audit report summaries are publicly available, ensuring our security standards consistently meet industry best practices.

Your privacy and data security are always our top priority. Kualian was designed with security at its core from day one.

When encountering connection issues, follow these 6 troubleshooting steps to resolve most problems:

1. Check Basic Network: First, confirm that your device is connected to the internet. Try opening a common website to verify connectivity. If the basic network itself has issues, the accelerator cannot function properly — fix your base connection first.
2. Restart App & Device: Fully close the Kualian app (clear it from background as well), then relaunch and try connecting again. If the problem persists, restart your phone or computer — this resolves most temporary network configuration conflicts.
3. Switch Acceleration Node: The currently selected node may be under maintenance or congested. Manually switch to a different region's node from the list. The system's intelligently recommended alternative nodes usually connect quickly.
4. Check App Permissions: Go to your device's system settings, find Kualian's app permission management, and ensure network access and background running permissions are granted. Some security software may block the accelerator — add it to your trusted list.
5. Update to Latest Version: Older versions may have known connectivity or compatibility issues. Check the official website or app store for updates and upgrade promptly for optimal compatibility and performance.
6. Contact Tech Support: If none of the above steps resolve the issue, contact our technical support team through the in-app "Help & Support" portal. Provide your device model, system version, and a description of the problem. Our technicians will provide a one-on-one solution within 24 hours.

Most connection issues are resolved within the first three steps. If you still can't connect, rest assured our support team is ready to help.
