About Acutis Firewall

Acutis Firewall is a parental control app that protects your family by blocking adult content, malware, and dangerous websites. All filtering happens locally on your device for maximum privacy.

Key Features

Content Protection

• Block adult and pornographic websites with a comprehensive blocklist

• Protect against malware and phishing attacks with real-time DNS filtering

• Optional blocking for gambling sites and social media platforms

• Works across ALL apps, not just browsers

Time-Based Controls

• Set daily screen time limits for specific sites or categories

• Schedule blocking during homework time, bedtime, or family hours

• Choose which days of the week rules apply

Parental Controls

• PIN-protect settings so children cannot disable protection

• One-tap activation with no configuration required

• Auto-start protection when device boots

Privacy First

• All filtering happens on your device - no data sent to external servers

• No analytics, tracking, or data collection

• DNS queries go directly to your system DNS or Cloudflare

• PIN stored with Android's encrypted storage

How It Works

Acutis Firewall creates a local VPN tunnel on your device to intercept DNS queries. When a blocked domain is requested, it returns "not found" - preventing the content from loading. Allowed traffic passes through normally with no slowdown.

Requirements

• Android 10 or higher

• No root required

What's new in 1.0.6

• New: uninstall protection - stops the app being uninstalled without the parent PIN • Removing protection now asks for the PIN, and alerts you if it is removed anyway • Detects when app storage has been cleared, which wipes the PIN • Fix: the notification's "Disable Firewall" action no longer bypasses the PIN • Time rules now require the PIN to delete or turn off • Settings now shows the real app version
