Yes. Biubiu VPN includes a Free VPN tier that can be used through daily check-in time. If you later need lower latency, higher bandwidth, or more node choices, you can upgrade to VIP dedicated routes.

No. The Biubiu VPN client includes the connection workflow, so beginners do not need to import subscriptions manually. Advanced users can still follow compatibility guides when needed.

Device limits depend on the plan. A personal plan covers everyday devices, while higher plans are better for phones, laptops, tablets, and home devices online at the same time.

Yes. Biubiu VPN is designed around China VPN use cases such as route congestion, protocol interference, AI access, and cross-border streaming. It is built as a practical VPN Service rather than a generic proxy list.

Update the subscription, try auto-route, confirm your system time, and check whether your client is current. If the issue continues, send the device model and screenshot to support.

Some return-to-China scenarios are supported. Overseas users can choose routes for services such as NetEase Cloud Music, Bilibili, iQIYI, and 爱壹帆 depending on node availability.

If direct download is slow, contact online support for a mirror link or check the Telegram channel for the latest client package.

Yes, if your router supports OpenWrt, Merlin, or Padavan firmware. Follow the router guide to configure the proxy core and share access with home devices.

Please click 'Forgot Password' on the login screen, and the system will send a reset link to your registered email. We recommend binding a frequently used email to prevent losing contact.

Yes. Biubiu VPN can optimize routes across public Wi-Fi, 5G, and campus networks while encrypting traffic to reduce exposure on shared connections.

Your ISP may see that an encrypted connection exists, but not the specific sites, content, or app traffic inside the tunnel.

No. We do not record browsing history, downloaded content, DNS queries, or mappings between your real IP and destination sites.

No VPN Provider can promise perfect invisibility, but Biubiu VPN uses protocol updates, Reality obfuscation, and route switching to reduce interference.

Biubiu VPN uses modern encrypted transport to protect login, payment, browsing, and app traffic on public Wi-Fi, hotel networks, and shared connections.

When the tunnel is active, websites see the Biubiu VPN node IP instead of your local IP. We recommend enabling DNS protection and Kill Switch for stronger coverage.

The Kill Switch blocks unencrypted traffic if the connection fails, reducing the chance that your real IP or requests leak during reconnection.

DNS requests are handled through the encrypted tunnel, which reduces pollution, forced redirects, and local network logging.

No. Biubiu VPN does not sell browsing data, inject advertising scripts, or build third-party ad profiles. Revenue comes from subscriptions.

That means the selected VPN node is active. You can switch between Hong Kong, Japan, the United States, Singapore, and other regions based on the service you need.

Yes. Streaming routes prioritize native IPs and lower-load nodes to help Netflix, Disney+, YouTube, and 爱壹帆 play with fewer region errors.

Yes for many games. Biubiu VPN is a general network accelerator rather than a single-title tool like UU加速器, 雷神加速器, or 迅游加速器, so it can support gaming, voice chat, and browsing together.

Some nodes permit P2P traffic. Choose routes according to node notes and follow copyright and platform rules in your location.

Every route can be affected by local networks and target platforms, but Biubiu VPN uses spare capacity, auto-route selection, and load balancing to reduce evening slowdowns.

Smart split tunneling keeps local apps on your normal network while overseas sites, AI tools, and streaming services use the accelerated VPN tunnel.

Some routes include basic filtering rules to reduce common pop-ups and risky domains. For detailed cosmetic blocking, a browser extension is still recommended.

Yes. Connection problems, client installation, account subscriptions, and route selection can be reported through tickets or Telegram.

Use auto-route first. The system weighs distance, node load, and real-time latency to pick a suitable route for your current network.

Yes. Sign in with the same Biubiu VPN account and your subscription rights will sync across supported devices.

You can buy a temporary data add-on or upgrade to a higher plan in the account center. Usage reminders appear before the limit is reached.
