quiz FAQ

Does Device Lab Pro drain my battery?

Device Lab Pro is optimized for minimal battery impact. You can adjust monitoring frequency in settings to further reduce battery usage.

Is my data sent to any servers?

No. All data is stored locally on your device. Device Lab Pro respects your privacy and does not transmit personal data.

Why does the app need Location permission?

Android requires Location permission to display WiFi network names. This is an Android security requirement, not a Device Lab Pro limitation.

Can I export my data?

Yes! Device Lab Pro supports export to CSV, JSON, PDF, GPX, and WAV formats from various features.

How accurate are the sensor readings?

Sensor accuracy depends on your device's hardware. Device Lab Pro reads directly from device sensors without modification.
