Understanding VPN Proxy Master: Company Background and Overview
VPN Proxy Master is a VPN service developed by Lemon Clove Pte. Ltd., a company incorporated in Singapore. Launched in 2018, the service has gained significant popularity, particularly among mobile users seeking free VPN solutions. The app is available across multiple platforms including Android, iOS, Windows, and Mac, offering both free and premium subscription tiers.
Before diving into the security analysis, it is essential to understand what VPN Proxy Master claims to offer: encrypted internet connections, anonymous browsing, access to geo-restricted content, and protection on public Wi-Fi networks. However, the critical question remains whether the service delivers on these promises without compromising user privacy.
Security Features and Encryption Analysis
Encryption Protocols Supported
VPN Proxy Master supports several encryption protocols, which is a positive indicator of its security capabilities:
- OpenVPN (UDP/TCP) - The industry-standard protocol known for its balance of security and speed
- IKEv2 - Preferred for mobile devices due to its ability to quickly reconnect
- V2Ray - Useful for bypassing network restrictions
- SSR (ShadowsocksR) - Alternative protocol for circumventing censorship
- Your real IP address can be exposed to websites you visit
- Your ISP can monitor your browsing activity despite using the VPN
- The fundamental purpose of using a VPN for privacy is undermined
- Browsing history and traffic content
- Destination websites and DNS queries
- IP addresses (both original and assigned)
- Connection timestamps and session durations
- Whether the company actually adheres to its stated policies
- The authenticity and originality of their privacy commitments
- The overall professionalism and trustworthiness of the organization
- United States (NSA)
- India
- South Korea
- Thailand
- Other Pacific region nations
- The app met Google's security standards for mobile applications
- Basic security practices are in place within the app code
- The app underwent testing by an independent security firm
- Casual users needing basic IP masking for non-sensitive browsing
- Users in regions where premium VPNs are unavailable or unaffordable
- Temporary VPN needs where security is not critical
- Journalists, activists, or anyone requiring strong anonymity
- Users in countries with oppressive internet surveillance
- Anyone handling sensitive business or financial data
- Privacy enthusiasts seeking maximum protection
- Users who cannot afford DNS leaks exposing their identity
- Consider the premium subscription to access the kill switch feature
- Regularly test for DNS leaks using independent testing sites like dnsleaktest.com
- Use OpenVPN protocol when possible for better security
- Avoid using the VPN for highly sensitive activities like banking or confidential communications
- Review app permissions and revoke any that seem unnecessary
- Keep the app updated to receive security patches
The default protocol varies by platform: IPSec for Android, IKEv2 for iOS, and OpenVPN for Windows. Users can manually switch between protocols based on their needs.
AES-256 Encryption
VPN Proxy Master advertises the use of AES-256 encryption, often referred to as military-grade encryption. This is the same encryption standard used by governments and financial institutions worldwide. In theory, this level of encryption is virtually unbreakable with current technology.
However, independent testing has raised concerns. Some reviews found that the Windows application was using AES-128-CBC encryption with 160-bit SHA1 for HMAC authentication, which is weaker than the advertised AES-256. While AES-128 is still considered secure for most purposes, this discrepancy between marketing claims and actual implementation raises questions about transparency.
Critical Security Concerns and Vulnerabilities
DNS Leak Issues
One of the most significant security concerns with VPN Proxy Master is the presence of DNS leaks during testing. DNS leaks occur when your DNS requests bypass the VPN tunnel and are sent through your regular internet connection, potentially exposing your browsing activity to your ISP or other observers.
Independent testing by VPN Overview and other security researchers found constant DNS leaks during their evaluation of VPN Proxy Master. This is a critical flaw because:
Malware and Permission Concerns
Security testing has detected potential malware and invasive permissions in VPN Proxy Master's Android application. While the severity and nature of these findings vary between testing methodologies, any detection of malware in a security-focused application is concerning.
Mobile VPN apps require certain permissions to function properly, but users should be wary of apps requesting unnecessary access to device features, contacts, or other sensitive data.
Kill Switch Limitations
A kill switch is a critical VPN security feature that blocks all internet traffic if the VPN connection drops, preventing accidental data exposure. VPN Proxy Master does include a kill switch feature, but it is only available to premium subscribers.
Free users are left vulnerable to data leaks if their VPN connection becomes unstable or disconnects unexpectedly. This paywall on essential security features is a significant drawback for privacy-conscious users on the free tier.
Privacy Policy Analysis and Logging Practices
What VPN Proxy Master Claims
According to VPN Proxy Master's official privacy policy and support documentation, the service follows a strict no-logs policy. They claim not to collect, store, or log:
Data That Is Actually Collected
Despite the no-logs claims, VPN Proxy Master does collect certain types of data:
| Data Type | Purpose | Concern Level |
|---|---|---|
| Country location | Service optimization | Medium |
| VPN server selection | Connection analytics | Low |
| Connection success status | Troubleshooting | Low |
| Subscription and transaction data | Account management | Low |
| Customer support correspondence | Support purposes | Low |
| Device diagnostics via Firebase | Crash reporting | Medium |
Privacy Policy Authenticity Concerns
A troubling discovery by TechRadar and other reviewers is that portions of VPN Proxy Master's privacy policy appear to be copied directly from ExpressVPN's privacy policy, with other sections seemingly borrowed from PureVPN's older policies. This raises serious questions about:
Lack of Independent Audits
Unlike leading VPN providers such as NordVPN, ExpressVPN, and Surfshark, VPN Proxy Master has not undergone independent third-party audits of its logging practices or security infrastructure. Independent audits are crucial for verifying that a VPN provider actually follows its stated privacy policy.
Jurisdiction and Legal Concerns
Singapore Location
VPN Proxy Master is headquartered in Singapore through its parent company Lemon Clove Pte. Ltd. While Singapore is not a member of the Five Eyes intelligence alliance, it is part of the SIGINT Seniors Pacific coalition, which includes:
This intelligence-sharing arrangement means that Singapore authorities could potentially be compelled to share data with partner nations. For users seeking maximum privacy, VPN providers based in privacy-friendly jurisdictions like Switzerland, Panama, or the British Virgin Islands may be preferable.
Data Retention Laws
Singapore has laws that can require companies to retain and provide user data to authorities under certain circumstances. While VPN Proxy Master claims not to log identifiable data, the legal environment in Singapore provides less protection than jurisdictions with stronger privacy laws.
Google Play Security Badge: What It Means
In 2025, VPN Proxy Master passed the Mobile Application Security Assessment (MASA) and received Google Play's Independent Security Review badge. This certification is valid from August 26, 2025, to August 26, 2026, and indicates:
However, it is important to understand the limitations of this badge. The MASA certification primarily focuses on app security rather than the VPN service's backend infrastructure, logging practices, or overall privacy protections. It does not guarantee that the VPN service itself is secure or private.
Comparison with Safer Alternatives
For users concerned about VPN Proxy Master's security issues, several alternatives offer stronger privacy protections:
| Feature | VPN Proxy Master | NordVPN | ExpressVPN | Proton VPN |
|---|---|---|---|---|
| Independent Audits | No | Yes (multiple) | Yes (multiple) | Yes |
| Kill Switch (Free) | No | N/A | N/A | Yes |
| DNS Leak Protection | Unreliable | Reliable | Reliable | Reliable |
| Jurisdiction | Singapore | Panama | BVI | Switzerland |
| Open Source | No | No | No | Yes |
| Free Tier Available | Yes | No | No | Yes |
Premium Alternatives
NordVPN offers robust security with an independently audited no-logs policy, double VPN servers, and reliable leak protection. It costs significantly less than ExpressVPN while offering comparable features.
ExpressVPN provides excellent ease of use, proven no-logs policy verified through real-world legal cases, and comprehensive streaming support. It is more expensive but offers premium reliability.
Free Alternatives
Proton VPN Free is the recommended free alternative. Based in Switzerland with strong privacy laws, Proton VPN offers a truly free tier with no data caps, no ads, and reliable security. The trade-off is limited server locations and slower speeds on the free tier.
Windscribe Free offers 10GB of data per month with strong privacy features and a transparent company approach.

Final Verdict: Is VPN Proxy Master Safe in 2025?
The answer to whether VPN Proxy Master is safe depends on your definition of safe and your specific use case. For basic browsing privacy and accessing geo-restricted content casually, VPN Proxy Master may provide adequate protection for low-risk activities.
However, for users who prioritize genuine privacy and security, VPN Proxy Master falls short in several critical areas. The DNS leak issues, concerning jurisdiction, lack of independent audits, copied privacy policy sections, and paywall on the kill switch feature all undermine confidence in the service.
The 2025 Google Play security badge provides some assurance of app-level security but does not address the fundamental concerns about the VPN service's infrastructure and privacy practices. Until VPN Proxy Master conducts independent audits, fixes its DNS leak problems, and provides greater transparency about its operations, security-conscious users should consider more established alternatives that have proven track records of protecting user privacy.
