Nuvrail: App Firewall

Your phone. Your apps. Your rules. Nuvrail lets you choose which apps can use Wi-Fi and mobile data. Block everything with one tap, or allow only the apps you pick. Rules run on your device through Android's local VPN service. No root required. WHAT YOU CAN DO - Allow or block internet access app by app, or all at once. - Search by app name or package and manage system apps. - Schedules: switch to a saved profile automatically on the days and hours you set. - Focus sessions: while a session runs, only your focus exceptions can go online. A short summary arrives when it ends. - Wi-Fi only: let chosen apps connect on Wi-Fi but not on mobile data. - Screen-off blocking: cut chosen apps while the screen is off. - New app alerts: get a notification when an app is installed, so you can set its access right away. - Block log: optionally see which blocked apps tried to connect and which DNS names they asked for. Off by default, stored only on your device and kept for 24 hours. - App lock: protect Nuvrail with your device screen lock or biometrics. - Widget: start protection and check its state from your home screen. FREE AND PLUS Core protection is free with no app limit. Nuvrail Plus is a one-time purchase, not a subscription. It unlocks saved profiles, JSON rule backups, schedules, focus sessions, Wi-Fi only, screen-off blocking and focus summaries. You can also watch an optional rewarded ad to try Plus on this device for 30 minutes. Ads are never required for core protection. When the time ends, your rules and profiles stay. PRIVACY AND LIMITS Nuvrail's firewall works on your device. It never sends traffic to a remote VPN server and never inspects or stores traffic content. Google AdMob serves optional ads; ad data handling and consent are described in the privacy notice. Google Play processes purchases. Please note: Android VpnService and system consent are required. Another VPN cannot run at the same time. Nuvrail does not hide your IP address. Rules apply only while protection is running. Apps sharing an Android UID change together. Nuvrail keeps its own connection for purchases and optional ads. Android's block-connections-without-VPN setting may also block allowed apps.
