Acutis Firewall
• 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
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
• No subscription - completely free and open source
