ONE SENTENCE
Nunya is a digital privacy screen for iPhone messages: your words stay readable
in your hand and illegible over your shoulder.

ONE PARAGRAPH
Nunya is a digital privacy screen for the messages on your iPhone. Type a
message and Nunya renders it as hybrid artwork: fine detail carries your real
words for the person holding the phone, while soft decoy characters take over
for anyone reading from a seat away. It works in the main app and as an iMessage
app, and the finished message can be sent through any chat app that accepts an
image. It is a visual privacy aid rather than encryption, built to discourage
casual shoulder surfing.

FULL STORY
Everyone reads messages in public. On a train, in a queue, in an open-plan
office, the person beside you can see your screen as clearly as you can.
Physical privacy screens fix that by dimming the display for everyone, including
you, and they have to be fitted to the phone.

Nunya takes a different approach, borrowed from the hybrid images described by
Oliva, Torralba and Schyns in 2006. Two visual layers are drawn at once. Fine,
high-frequency detail carries the private message and is legible close up. A
soft, low-frequency layer of cover characters sits on top of it and dominates at
a distance. Up close your eyes resolve the fine detail. Farther away that detail
falls away and the cover pattern is what is left.

Because the effect depends on how far away the reader is, Nunya calibrates to
the person using it. The front camera can estimate how far you hold your phone,
on device, and pick a matching readable distance; manual setup does the same job
without the camera.

Nunya is not encryption. It is an optical effect, and it is honest about what
that buys: it beats the glance from the next seat, not someone standing over you
reading deliberately, and anyone the message is sent to reads it normally.

KEY FEATURES
- Type directly into the artwork, so your words never appear in an ordinary
  visible text field.
- Three readable distances, Close, Medium and Far, plus an advanced slider for
  setting an exact distance.
- Optional automatic setup uses the front camera to estimate your reading
  distance; face position is processed on device and nothing is stored.
- A dedicated iMessage app for writing and sending without leaving a
  conversation.
- Recipients who also have Nunya can re-read a message at their own distance.
- Recipients without the app still receive branded artwork made to be read by
  holding the phone close.
- Share through WhatsApp, Signal, Telegram, Mail or any other app that accepts
  an image.
- No account, no sign-in, no analytics and no data collection of any kind.
- Free to try with five sends included; a single in-app purchase unlocks
  unlimited sending for $4.99 / GBP 4.99, with no subscription.
