FAQ

Frequently Asked Questions

Is there any internet requirement or background telemetry tags?

No. This application performs absolutely zero database synchronization, server reporting, or analytics harvesting. All configured marquee slogans and parameters reside strictly on your local physical device inside the SQLite database.

How does Head-Up Display (HUD) Mode work practically?

When enabled via control sliders, it mirrors all layout elements. Placing your mobile device flat on your vehicle's dashboard with the scroller active causes standard light reflections to appear clear and upright on your windshield, making it incredibly easy to configure temporary transport signs!

Are there any lengths constraints on the animated exports?

Export steps capture frame canvases dynamically byte-by-byte. For very long screens, you can custom-define target frames up to hundreds of intervals to manage high-fps sequences cleanly matching your storage bounds.

How do I export my marquee as a Video or GIF?

On the main Home Dashboard (the main control interface), scroll down past the text box, color pickers, and matrix options. Right above the primary Start Scroller button, you'll find dedicated buttons to "Render & Export MP4 Video" and "Render & Export GIF". Tapping either will instantly capture your customized scroller sequence directly into a shareable animation file!

Can I display multiple sentences in a sequence?

Yes! Simply enter multiple sentences in the text box separated by commas. The application will automatically detect the comma-separated values and display them in a continuous sequence, allowing you to create longer, richer announcements.

What is the advanced Auto-Lock feature?

For advanced scenarios (like window shops), the app offers an Auto-Lock functionality that uses Android's Device Administrator privileges. It turns off your screen automatically when an LED session completes or an Auto-Exit timer hits zero. Because this application operates 100% offline, we cannot remotely unlock your device or retrieve PINs; any use of this feature is strictly at the user's explicit setup and risk.

Are there any medical or hardware risks to know about?

Yes. Like any visual application utilizing flashing colors or intense contrasts, this app may trigger photosensitive seizures. Additionally, setting your device to maximum brightness with static shapes for prolonged hours can result in screen burn-in (especially on OLED devices). Please refer to the EULA for full medical and hardware condition warnings. Always use such features responsibly.
