Should Firewall AI also remain activated at night?

Yes, it definitely makes sense to leave Firewall AI turned on at night as well — for several reasons:

• Maximum security around the clock
  Even when your smartphone is idle, apps can still remain active in the background and establish data connections without you noticing. Firewall AI ensures that only desired connections are allowed and effectively protects you from unwanted data transfers or possible cyber threats.
• Protection against hidden threats
  Many spyware apps and trackers are designed to run quietly in the background — often exactly when you are not actively using your smartphone. With the continuous monitoring of Firewall AI, combined with Anti Spy, your device stays optimally protected at night as well.
• Intelligent, resource-efficient operation
  Firewall AI is designed to work extremely efficiently and with minimal resource use. That means your smartphone does not suffer excessive battery drain or performance loss when the firewall is active. If you are concerned about battery or power usage: don’t worry — Firewall AI was intentionally designed to have only a minimal impact on your battery.
• Control over app connections
  If you charge your smartphone overnight or leave it connected to Wi-Fi, some apps may try to sync or send data without you noticing. With Firewall AI, you keep full control over which apps are allowed to access the internet even in standby mode.

So feel free to keep Firewall AI activated continuously to protect yourself around the clock — without compromising performance or battery life.
