1 - Web Ad Blocking

Basic Principles of Ad Blocking

NullPrivate uses DNS filtering technology to monitor and analyze network requests in real time. When an ad-related domain request is detected, the system automatically returns an empty address or a local loopback address, thereby preventing ad content from loading. This approach is both efficient and transparent to the user, without affecting normal browsing.

Intelligent Blacklist System

NullPrivate employs a multi-layer blacklist management mechanism:

• Auto-Update: The system periodically fetches the latest ad domain lists from trusted sources
• Category Management: Domains are classified by type—ads, trackers, malware, etc.
• Performance Optimization: Uses efficient matching algorithms for fast response
• Statistical Analysis: Provides detailed blocking statistics so you can see the protection in action

Flexible Whitelist Control

The whitelist feature offers precise access control:

• Access Protection: Only allows access to trusted sites
• Scenario Customization: Ideal for anti-addiction and enterprise network management
• Simple Configuration: Supports import/export for easy management
• Real-Time Effect: Changes take effect immediately without service restart

Usage Recommendations

1. Start with the basic blacklist and adjust gradually
2. Regularly review blocking statistics to understand system effectiveness
3. Promptly add domains to the whitelist when false positives occur
4. Customize filtering rules for special needs

Technical Details

DNS Filtering Mechanism

• Uses high-performance DNS response caching
• Supports IPv4 and IPv6 dual-stack filtering
• Millisecond-level local response speed

Rule Matching

• Exact domain matching
• Wildcard rule support
• Regular expression matching

Performance Optimization

• Memory-optimized data structures
• Concurrent request handling
• Intelligent caching mechanism

2 - Mobile Ad Blocking

Problem Overview

Many Android devices ship with pre-installed adware that:

• Pops up ads at inappropriate moments
• Continuously collects user data in the background
• Consumes system resources, causing performance degradation
• Generates unnecessary network traffic
• Significantly shortens battery life

AdGuard Solution

“NingPing” protects your device by:

• Blocking network requests from adware
• Preventing malicious tracking
• Optimizing device performance
• Extending battery life
• Reducing mobile data usage

3 - Privacy Protection

The Relationship Between Privacy and Advertising

Advertisers’ revenue primarily comes from ad conversions. To boost conversion rates, platforms need to:

1. Increase user retention
2. Serve personalized ads

This requires extensive collection of user privacy data. Platforms circumvent legal restrictions through:

• Complex user agreements
• Data exchanges with partners
• Disguised data anonymization

Privacy Protection Priority

Protecting privacy is more important than simply blocking ads:

• AdGuard’s Chinese filter has far more tracking rules (>400k) than ad rules (<100k)
• Some platforms have few ads yet profit more by monetizing privacy data

Behind the Platform’s “Thoughtfulness”

So-called personalized recommendations often don’t truly understand user needs; they’re marketing tactics:

• “You’ll like this” actually means “I want to sell this”
• Seemingly thoughtful services hide continuous data collection

How to Protect Yourself

Learn “cyber shrewdness” — control privacy leaks and avoid being accurately profiled by platforms. AdGuard Personal Service can help you achieve this.

4 - Malware Blocking

What is Malware?

Malware is a category of software designed to damage or gain unauthorized access to computer systems. It may:

• Steal personal information and sensitive data
• Disrupt system functions and files
• Encrypt data for ransom
• Recruit devices into botnets

How Malware Spreads

Hackers typically spread malware through the following methods:

• Download links disguised as legitimate software
• Attachments in phishing emails
• Vulnerable websites
• Infected advertisements

How AdGuard Protects You

“NingPing” provides comprehensive malware protection:

• Blocks known malware download links
• Prevents communication between malware and command-and-control servers
• Identifies and stops suspicious data exfiltration
• Regularly updates malware signature databases

It is recommended that you also adopt additional security measures, such as keeping your system and software up to date and exercising caution when downloading and opening attachments.

5 - Adult Content Blocking

Feature Overview

“NullPrivate” employs a multi-layer content filtering mechanism that can effectively identify and block:

• Pornographic and adult content sites
• Violent content
• Gambling-related sites
• Other harmful information

How It Works

The system achieves content blocking through:

1. DNS-level blocking: Prevents domain resolution of known harmful sites
2. Intelligent categorization: Classification system based on multiple trusted data sources
3. Real-time updates: Regularly updated blocking rules to ensure protection effectiveness

Configuration Guide

Basic Settings

Add the blocklist Link to the filter blacklist

Advanced Options

• Custom rules: Add specific sites to the blocklist
• Exception management: Set up whitelists to avoid false positives
• Access logs: View blocking records

Application Scenarios

• Enterprise management: Ensure employee access to work-appropriate sites
• Public spaces: Suitable for public networks in libraries, schools, etc.

Notes

1. Recommended to use in conjunction with anti-addiction features
2. Regularly check and update filtering rules
3. If false positives occur, promptly add to whitelist
4. If circumvention is detected, submit feedback

6 - Social Network Blocking

Risks of Social Network Tracking

Social network platforms collect user data through various means:

• Social plugins and share buttons

With these measures, you can continue using the core features of social networks while protecting yourself from unwanted tracking and data collection.

7 - Phishing Site Blocking

What is a phishing site?

A phishing site is a fraudulent website that masquerades as a legitimate one in order to obtain sensitive information such as personal details and account passwords. These sites usually imitate:

• Banks and payment platforms
• Social networks
• E-commerce sites
• Government agency websites

Main risks

• Stealing user accounts and passwords
