If you decide to permanently stop using NullPrivate, it must mean our service has caused you inconvenience. We sincerely apologize for any inconvenience caused.
Our public service uses popular blocking rules. Due to limited resources, we cannot track all cases of under-blocking or over-blocking for every app.
If you wish to customize rules for personalized needs, consider purchasing private service. Our private service offers dedicated solutions at exceptional value to meet various requirements.

3 - How to Handle False Blocking

Some services are considered necessary by some users but viewed as personal information collection or advertising by others. For example, WeChat and Alipay may contain small programs that mix services with ads, making them unusable. Payment redirects such as parking lots or vending machines may also fail to function properly.

If strict blocking rules are set, these services may be blocked, causing service disruptions.

Temporarily Disable Protection

If you need an urgent, temporary solution, you can resolve the issue by temporarily disabling protection, which typically takes effect within 10 seconds.

Add Service to Whitelist

For services used long-term, you can add them to the whitelist to prevent future blocking. This usually takes effect within 10 seconds.

Temporarily Suspend Settings

Public service users can resolve the issue by temporarily suspending the service, which typically takes effect within 60 seconds.

6 - Slow Access to Some Websites

Slow Access to Some Video Sites

If you experience slow access to certain websites while using NullPrivate, it may be due to the following reasons:

ECS Support:

NullPrivate’s free tier does not support ECS (Extended Client Subnet). ECS is a DNS protocol extension that allows DNS servers to provide more accurate responses based on the client’s network location. Many CDNs (Content Delivery Networks) use ECS to direct users to the nearest server, thereby improving speed. The free servers are located in Shanghai and Hangzhou.

Impact:

• Slower Speeds: Without ECS, NullPrivate may be unable to direct you to the optimal CDN server, resulting in slower speeds.
• Inaccurate Geolocation: You may be routed to a server far from your actual location, increasing latency.

Solutions:

• Upgrade to Paid Plan: NullPrivate’s paid plans support ECS, which can resolve this issue and improve speed.
• Use Another DNS Server: You can try another DNS server that supports ECS.
