HOLLER
Hold your phone up and let the room read it.
Type a message, turn the phone sideways, and it fills the screen. Make it big, set it in motion, and let it carry farther than your voice can.
Holler contains no networking code. Not "we don't collect data" — it physically cannot. No analytics, no accounts, no servers.
USE, TROUBLESHOOTING, AND PRIVACY.
Does it need an internet connection?
No. Holler has no networking code at all, so it works in aeroplane mode, in a basement venue, and on a dead network.
Is there a subscription?
No. Everything is a one-time purchase, and unlocking everything covers future styles and add-ons too.
What does the free version do?
The whole core. Type a message, turn the phone, and show it at any size, colour, and speed you like. Paying unlocks the decorative styles and effects.
Why did my screen get brighter?
The screen goes to full brightness while your message is up so it can be read across a room. It returns to where it was when you close the display.
Does it flash?
Only deliberately, and only slowly. Flash and Strobe are capped below three pulses per second, and Reduce Motion disables both.
Are my messages stored anywhere?
Only on your device, and only the ones you actually showed. Read the full policy here: offln.dev/holler/privacy
