About this app

Linkblock is a powerful privacy protection tool that makes web browsing on your smartphone safer and more comfortable.

It blocks malicious sites and trackers that track user behavior at the DNS level, providing a secure internet environment.

Key Features and Characteristics
• Tracker Blocking: Blocks communication with trackers (tracking programs) lurking on websites, protecting your privacy.
• Malware and Phishing Protection: Prevents access to known dangerous domains, protecting your device from threats.
• Data Saving: Blocks unnecessary communication (tracker scripts, etc.) before downloading, saving data usage and improving page loading speed.
• Custom Filters: Allows users to add their own filter URLs (text format) for customization to suit their preferences.

Completely Local Processing and High Security
Linkblock does not use external servers. It utilizes Android's VpnService to build a "local VPN" within the device, completing all DNS filtering processing solely on the smartphone.

Privacy Commitment
We prioritize our users' privacy.

• We will not send your browsing history or communication content to external servers.

• We do not collect, store, or share any personal information or logs.

*This app uses the standard Android VPN Service API for the purpose of filtering DNS traffic. By default, only communication from major browser apps is protected.
With device-based DNS filtering, it blocks malicious trackers while you're browsing the web, protecting your privacy. It's also ideal for saving on data usage.
