A VPN adds an encrypted tunnel between you and the internet, which lowers the chance of casual eavesdropping on plain HTTP in untrusted networks. Below is a practical checklist plus notes on privacy, technology, and how we operate.
1. Install only from official sources
- Use official app stores on mobile and the official 5UF website (or links we publish) on desktop; verify the domain before installing.
- Avoid “cracked” builds and random APK shares. Many free or unknown VPNs have a poor track record for ads, data resale, or malware.
2. Account work only on real HTTPS sites
For login, billing, or subscription pages, confirm a trusted domain and HTTPS in the address bar.
3. After connecting, test your IP and DNS (recommended)
With the VPN on and other proxies off, open BrowserLeaks — My IP Address to see the exit IP and rough region. The same site offers DNS leak and WebRTC tests. Results depend on split tunneling, extensions, and dual-stack networks—use them as signals, not a single proof.
4. Can ISPs or police “know I use a VPN”?
Technically, providers often see that your device talks to a remote endpoint with encrypted traffic, volume, and timing. They generally cannot read your HTTPS page contents the way they could with old plain HTTP. Sites and modern apps add another layer of end-to-end TLS that the VPN operator normally cannot decrypt either. What authorities may obtain still depends on law and due process—a VPN is not invisibility.
5. Xray-based stack
Our service commonly builds on open projects such as Xray (for example XTLS/Xray-core) with transports like Trojan wrapped in TLS. Open source enables community review; it is not the same as a formal proof against every adversary, but it is far more inspectable than a closed black box. Keep clients updated and download only from trusted sources.
6. What can the operator see?
In typical HTTPS browsing, we cannot decrypt the payload between you and the website. Exact data categories are spelled out in our privacy policy.
7. Singapore company and compliance
We are incorporated in Singapore and operate under its legal framework. The privacy policy explains retention, security practices, and how we may respond to lawful requests. We do not treat selling user privacy as a business model. Read the policy on our site; open a ticket for questions.
8. Bottom line
No VPN replaces good hygiene—official clients first, skepticism toward “free” unknown VPNs, and regular updates. Report suspicious clones through official channels.
