Frequently Asked Questions

How do I use Signal Server? Open the app, swipe to the signal you need, and place your phone face-up on the table. Your server will see the message on your screen.
How do I change the language? Tap the language code button (e.g. "EN") in the bottom-left corner of the main screen to choose from 55 supported languages.
Can I create my own signals? Yes. Tap the grid icon in the bottom-right corner, then tap "Add Custom" to create a signal with your own text, color, and icon.
How do I keep the screen bright? Tap the sun icon in the top-right corner to boost your screen brightness to maximum. Tap again to return to your normal brightness.
Will my phone stay awake? Yes. Signal Server automatically keeps your screen on while the app is open so your signal stays visible.
Is my data stored online? Your custom signals and preferences are stored locally on your device. If you submit feedback through the in-app form, only the feedback text and category are sent to our server. No personal information is collected. See our Privacy Policy for details.
How do I delete my data? Uninstalling the app removes all locally stored data (custom signals, language preferences, settings). Feedback submitted through the in-app form can be deleted upon request by contacting us.
