Acutis Firewall

Parental control app that blocks adult content and dangerous sites on-device.
New in version 1.0.5
• Make blocklist downloads opt-in: no remote fetch on first launch
• First launch now prompts before downloading blocklists

• Toggling a category on with no rules downloads just that category
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
• No subscription - completely free and open source

Named after Blessed Carlo Acutis, patron of the internet.
