Android Firewall: No Root

Android Firewall is a rootless Android firewall that lets you control which apps can access the internet. Block or allow internet access for individual apps without root access or a remote VPN server. Android Firewall works locally on your device using Android's VPN interface.

PER-APP INTERNET CONTROL

Choose how your apps access the internet:

• Allow all apps
• Block selected apps
• Allow only selected apps
• Block all non-critical apps
• Search user and system apps
• Keep selected apps at the top of your allow and block lists

TEMPORARY INTERNET ACCESS

When using Allow list mode, apps that do not have a decision can request internet access.

You can choose:
• Always allow
• Always block
• Allow temporarily for a custom duration

This gives you more control without permanently changing your firewall rules.

LOCAL BLOCKED-CONNECTION LOGS

See which apps tried to connect when their internet access was blocked.

View:
• App name
• Destination IP address
• Port
• Protocol
• Time
• Visible plain-DNS hostname

You can clear your logs or export them as CSV.

PRIVACY BY DESIGN

Android Firewall is designed to keep firewall activity on your device.

• No root access required
• No account or login
• No advertisements
• No analytics SDK
• No DigiComfy-operated remote VPN server
• Firewall rules, access requests and logs stay on your device

Android Firewall does not decrypt messages, passwords, payments, browser content or files.

HOW IT WORKS

Android Firewall uses Android's VpnService as a local packet-blocking firewall.

Depending on the selected mode, traffic that you choose to block is routed into an on-device VPN tunnel and dropped. Allowed apps continue to connect normally.

RELIABLE CONTROLS

• Optional protection restart after device boot
• Persistent notification while protection is active
• Stop protection at any time
• Supports Android 8.0 and newer

IMPORTANT

Android allows only one active VPN service per user. Android Firewall cannot run at the same time as another VPN app.

Do not enable Android's "Block connections without VPN" option with this drop-only version because intended bypass traffic may be denied.

Android Firewall gives you simple, local control over app internet access without requiring root.
