FAQ
Everything you need to know about Yafu Accelerator
What are the fundamental differences between Yafu Accelerator and other accelerators on the market?
Yafu Accelerator's primary distinction from traditional accelerators lies in its underlying protocol. Most accelerators still use IPsec or IKEv2, while Yafu Accelerator exclusively employs the WireGuard protocol, which comprises only 4000 lines of code (compared to over 600,000 for IPsec), boasting a 3-5 times speed increase and significantly reducing battery consumption. Moreover, Yafu Accelerator's no-logs policy has been independently audited by Cure53, with the audit report fully disclosed, achieving a true balance of speed and security.
What operating systems and devices does Yafu Accelerator support?
Yafu Accelerator offers native client support across platforms, including Windows 7 and above, macOS 10.14 and above, iOS 14 and above, Android 6.0 and above, and major Linux distributions (Ubuntu, Fedora, Debian, etc.). Additionally, Yafu Accelerator provides detailed router configuration tutorials for popular firmware like Asus, Netgear, and OpenWrt, allowing a single setup to protect all connected devices in your home.
How do I get a refund if I'm not satisfied with Yafu Accelerator?
Yafu Accelerator has a 30-day unconditional refund policy. If you are unsatisfied with the service within 30 days of purchase, just contact the support team via online chat or email support@vpnjs.net for a full refund without needing to provide any reasons. Refunds are typically processed within 1-3 business days back to your original payment account.
What connection speeds can I actually achieve with Yafu Accelerator?
Yafu Accelerator has deployed over 3000 high-speed server nodes globally, with actual test results showing average latency under 30ms for connections to Asia-Pacific nodes, around 80-120ms for North American nodes, and download speeds consistently reaching above 500Mbps on gigabit broadband. Thanks to the high efficiency of the WireGuard protocol, Yafu Accelerator maintains stable connections even in complex network environments.
What does Yafu Accelerator's no-logs policy encompass?
Yafu Accelerator's no-logs policy covers all aspects: we do not log original IP addresses, connection timestamps, visited websites or domains, DNS queries, or traffic bandwidth usage data. All servers operate in a pure RAM environment, automatically clearing data upon physical reboot. This policy has been rigorously evaluated by the internationally recognized security audit firm Cure53, with the complete audit report available on the Yafu Accelerator website.
Yafu Accelerator provides comprehensive router configuration tutorials supporting popular firmware like Asus (Asuswrt-Merlin), Netgear, Linksys, OpenWrt, and others. The configuration steps typically include: 1) logging into the router management interface; 2) going to the acceleration client settings; 3) importing the configuration file provided by Yafu Accelerator; 4) entering your Yafu Accelerator account credentials. Once configured, all devices connecting to that router's WiFi will automatically receive accelerator protection without needing to install clients on each device individually.
Yes, Yafu Accelerator is specifically optimized for streaming performance. Our high-speed nodes can smoothly play 4K ultra-high-definition video content. Yafu Accelerator regularly updates the server IP pool to ensure a stable streaming experience. However, please note that Yafu Accelerator does not encourage users to violate any streaming platform's terms of service.
Thanks to the efficient design of the WireGuard protocol, Yafu Accelerator has minimal impact on speed. In most cases, speed loss does not exceed 5-10% of the original bandwidth. In some instances, if your ISP throttles specific traffic (like video streaming or P2P), using Yafu Accelerator may actually improve speed, as the encrypted connection prevents the ISP from deep packet inspection (DPI) and traffic identification.
Yes, the Lightning Version of Yafu Accelerator supports up to 6 devices connected simultaneously, while the Flagship Version allows for up to 10 devices. This means you can use accelerator protection on smartphones, computers, tablets, smart TVs, and more without any extra fees. If you need to protect more devices, configuring Yafu Accelerator on your router can safeguard all connected devices in one setup.
Public WiFi is a high-risk scenario for hackers to steal data. Once connected to Yafu Accelerator, all your internet traffic is transmitted through AES-256 encrypted connections, ensuring that even if someone attempts to conduct a man-in-the-middle attack or sniff data on the same WiFi network, they cannot read your information. Yafu Accelerator also offers an automatic connection feature that activates accelerator protection when an insecure WiFi network is detected.
Yes, Yafu Accelerator's no-logs policy has been independently audited by the internationally recognized security firm Cure53. The audit team conducted a thorough examination of Yafu Accelerator's server infrastructure, codebase, and operational processes, confirming that Yafu Accelerator does not record any identifiable user data. The complete audit report is publicly accessible on the Yafu Accelerator website.
Yes, Yafu Accelerator offers a native Linux command-line client supporting major distributions like Ubuntu 18.04+, Debian 10+, Fedora 33+, CentOS 8+, and Arch Linux. Installation methods include one-click installation through APT/YUM repositories, as well as manual installation of .deb or .rpm packages. The Linux client supports core features such as the WireGuard protocol, split routing, and kill switch.
Yes, the Flagship Version of Yafu Accelerator includes an exclusive static IP address. Static IPs are particularly useful for scenarios such as remote access to company networks or NAS, running online services that require a fixed IP, or avoiding CAPTCHA challenges caused by frequently changing IPs. The static IP is assigned solely for your use and will not be shared with other users.
Yafu Accelerator includes comprehensive leak protection mechanisms: DNS leak protection ensures all DNS queries are resolved through encrypted connections; WebRTC leak protection prevents browsers from exposing your real IP through the WebRTC interface; and IPv6 leak protection guarantees IPv6 traffic is also secured. You can use the built-in leak testing tool in the Yafu Accelerator client or visit third-party testing sites to check your protection status.
Yafu Accelerator's proprietary obfuscation protocol disguises accelerator traffic as regular HTTPS traffic, effectively countering deep packet inspection (DPI) techniques. In environments with strict internet restrictions, Yafu Accelerator’s obfuscation mode can assist users in overcoming blocks and restoring access to the free internet. However, please note that Yafu Accelerator advocates responsible use of accelerators in accordance with local laws and regulations.
Yafu Accelerator supports various secure payment methods: Visa/Mastercard international credit and debit cards, PayPal, Alipay, WeChat Pay, and cryptocurrencies (Bitcoin, Ethereum, etc.). Choosing cryptocurrency payment can offer additional anonymity. All payment channels are processed through PCI DSS certified secure gateways to ensure your payment information's safety.
