FAQ

Q: How does the app ensure my personal browsing data remains private and secure?

A: Privacy is a core pillar of the Traffic Light philosophy, which is why the application operates on a "Zero Data Upload" principle. All network monitoring occurs strictly on your local device, and no usage data is ever transmitted to external servers. Because the project is open-source, the entire code base is available for public audit to ensure there is no hidden telemetry or malicious data collection.

Q: I use two different service providers; does Traffic Light support dual-SIM configurations?

A: Yes, the application is fully equipped to handle dual-SIM devices and allows you to monitor usage against different cellular plans simultaneously. It can distinguish between the two sources and can even manage automatic plan changes to ensure your tracking remains accurate regardless of which SIM is active for data.

Q: Will keeping a network monitor running in the background significantly impact my battery life?

A: Traffic Light is designed with a battery-friendly engine specifically optimized for low-impact background polling. Unlike many competing apps that constantly wake the processor, this app uses an efficient monitoring system that consumes significantly less power while maintaining a lightweight RAM and storage footprint.
