VPNsecurity guide for beginners: accounts, subscription links and public Wi-Fi

Your account and subscription link: keep them separate

Use a unique password for your service account. Don’t reuse passwords from your personal email, payment account, or work systems. A trusted password manager can generate and store it, but be sure to protect the password vault itself. VPNFund doesn’t require an email address; you can open an account with a username and password. That means you provide less information when getting started, but don’t assume there’s an email-based recovery option. Check the account dashboard or ask support about available recovery methods.

A subscription link isn’t an ordinary tutorial URL. It typically contains account-linked access credentials that a client uses to retrieve servers, connection settings, or rules. Someone who gets your link may be able to import your configuration and use your traffic allowance; what they can access depends on the service’s API. Even if the link can’t be used to sign in to your dashboard, treat it as sensitive information.

Client sources and import permissions

Verify the software through the client download page in the service dashboard and the developer’s official release channels. Similar names in search results, chat attachments, or reposted pages don’t prove who published the software. Before downloading, check the domain, publisher, and supported operating system. If installation instructions tell you to disable system security protections, stop and verify the source first.

The subscription format must be compatible with your client. Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different proxy protocols or implementations; support for one doesn’t mean a client can handle every configuration. Subscription links may also be designed for a specific format. If an import fails, check the client type, supported protocols, and subscription instructions. Don’t keep pasting the full link into unfamiliar converter sites.

Mobile operating systems may ask you to add a VPN configuration, while desktop clients may request network extension or virtual network adapter permissions. These permissions let the client route the relevant traffic, but an authorization prompt doesn’t verify that the software is trustworthy. Importing a subscription in an app is also different from installing a system profile. The latter may involve certificates or device management settings, so read each requested permission carefully. Don’t install an unknown certificate just to fix an ordinary connection issue.

Public Wi-Fi: verify the network before using it

Public network risks go beyond whether someone can read web pages. A hotspot with a similar name may trick you into connecting to the wrong network, a captive portal may imitate a sign-in page, and the local network may interfere with DNS resolution or unencrypted connections. Ask staff to confirm the network name, turn off automatic connections to unfamiliar hotspots, and don’t assume a stronger signal means a safer network.

HTTPS usually protects data in transit between your browser and a website, but it doesn’t prove the site itself is trustworthy or stop you from entering your password on a fake page. Don’t dismiss certificate warnings. If a network sign-in page asks for an account password unrelated to internet access, stop. Before signing in or paying, check the domain and certificate status.

• ✅ Confirm the hotspot name before connecting, and turn off unnecessary file sharing and device discovery.
• ✅ If authentication is required, complete it first, then start your client and check the actual traffic route.
• ✅ If an important task triggers an unexpected redirect or certificate warning, pause and switch to a trusted network.
• ❌ Don’t install root certificates, management profiles, or unknown clients suggested by a hotspot page.
• ✅ Disconnect when you leave and remove any saved public networks you no longer need.

A network acceleration connection can protect covered traffic between your device and the service’s exit server. It can’t fix a compromised device or make a phishing site trustworthy. When using proxy software, also check whether apps outside your browser actually use the connection.

Traffic routing rules and DNS: check the actual route

Split tunneling rules use domains, addresses, or app settings to decide whether traffic goes through the proxy or connects directly. System proxy settings usually affect only apps that follow them. A virtual network adapter can cover more traffic, but routing, exclusion rules, and the operating system’s implementation still matter. So, opening one webpage doesn’t prove that all your apps are covered.

DNS translates domain names into addresses. If a query that should go through the proxy is still sent to a resolver on the local network, the domains you visit may be exposed. That doesn’t mean the page content itself has been read. Conversely, even when DNS traffic is encrypted, the resolver may still see your queries. Check the client’s DNS policy and routing rules rather than looking only for an “encrypted” toggle.

1. Note the current client mode, selected server, and target app. Avoid changing several settings at once.
2. Check the rules and confirm that the target app and domain are within the expected proxy scope.
3. Use a trusted IP and DNS leak test to review the results. Remember that the test site itself can receive test information.
4. Check again after switching networks or resuming from sleep. If the results look unusual, pause sensitive activity and consult the client’s documentation.

Interpret test results in context. A domain allowed to connect directly may resolve locally without indicating an unexpected leak. A browser’s built-in secure DNS can also affect what you see. Check the client and operating system to confirm whether the kill switch covers system traffic; don’t assume it’s always active just because an option with that name appears in the interface.

Getting started and paying: share only what’s needed

You don’t need an email address to open a VPNFund account. Never enter your account password or full subscription link in a refund form, unofficial questionnaire, or chatbot. A payment page may be provided by a payment processor. When redirected, verify the order amount, recipient, and page source. Payment verification details are not the same as your service account password.

First, check how traffic is billed. Monthly subscriptions include ¥9.9/month for 60GB, ¥18/month for 250GB, and ¥28/month for 500GB; traffic resets monthly on your activation date. Mid-cycle upgrades are prorated based on the remaining days. Data bundles cost ¥158/300GB, ¥358/1000GB, and ¥658/3000GB; they last until used and never expire. These options follow different reset rules. See the plans page for full pricing.

Refund policy: you can request a full, no-questions-asked refund within 7 days of your first payment. Keep your order confirmation and contact support through official channels. A successful payment doesn’t mean your configuration is set up correctly. There’s no device limit, but that doesn’t mean you should share your account or subscription credentials.

Privacy policy and what to do after exposure

VPNFund’s privacy commitment is a no-logs policy. This describes the service’s approach to data handling; it doesn’t mean there are no records anywhere along the entire connection path. Websites, account logins, browser extensions, your device’s operating system, and payment providers each handle information in their own ways. Assess risk by considering separately who can see what, rather than treating a policy term as a blanket guarantee.

If you notice unusual traffic use, suspicious account activity, or an accidentally shared subscription link, stop spreading the information. Change your password through a trusted access point, check whether the dashboard offers subscription resets or session management, and use the features available. After revoking old credentials, import the subscription again and delete chat attachments or publicly shared files. Deleting a message you sent doesn’t prove that nobody saved a copy.

For help, use the support ticket page and include your operating system, client name, the step where the issue occurred, and the error message. Redact subscription links, QR codes, and sensitive payment information from screenshots, and check logs before sharing them. Don’t post your full configuration publicly to troubleshoot an issue.
