Privacy policy

Effective: 23 October 2026 · Operator: zarkon.co.uk (Richard Ross)

LED Sign Board turns your phone into a scrolling LED or neon sign. It works offline on your device.

Data we do not collect

• No accounts and no cloud sync. Your messages never leave your phone.
• No advertising ID.
• No microphone, camera, location or contacts.

Data stored on your phone

Your message, saved signs, look and motion choices, display settings (keep screen on, full brightness, landscape lock) and whether you own Pro are stored on your phone only. Uninstalling the app removes them.

Screen brightness

With Full brightness on, the app turns the screen up while it is open. It does not change your phone's brightness setting, and your normal brightness comes back when you leave the app.

Purchases

The one-time Pro unlock uses Google Play Billing. Google processes the payment; LED Sign Board only keeps a note on your phone that Pro is unlocked.
