## What is OTN?

OTN applies the mental model of a one-time password to your notes. Every note is born with a lifetime — 10 minutes, an hour, a day, a week — and quietly disappears when its time runs out.

Most notes are one-time information: where you parked, a wifi password, today's to-do. They don't deserve permanent storage. OTN is built for exactly this — write it in five seconds, let it go, and never watch your list pile up again.

WATCH IT FADE
Notes visually age as their time runs out, dimming and blurring until they dissolve. The list itself is the timer.

KEEP ONLY WHAT MATTERS
Tap a note to Keep it forever, or Release it now. Keeping is a deliberate act, not the default.

NOTHING IS LOST BY ACCIDENT
Expired and released notes rest unseen in the Archive for a while — then they're gone for good. Restore anything before it vanishes.

DESIGNED TO DISAPPEAR
A dark, minimal, single-screen interface. No folders, no tabs, no clutter. Choose from three typefaces to make it yours.

OTN PRO
A single one-time purchase removes ads on iPhone and syncs your notes between iPhone and Mac via iCloud.

Nothing piles up. As it should be.
