## What is Dayfly?

Dayfly is for notes you only need for a little while.

Notes quietly disappear after 24 hours by default. Parking spots, Wi-Fi passwords, locker numbers, today-only reminders — jot it down and forget about it. Dayfly cleans up after itself.

Attach photos and videos too. That whiteboard, a receipt, a photo you only took to ask an AI about — capture it and share it straight from Dayfly. Dayfly-managed attachments are removed when an expired note is cleaned up. Photo-library originals and shared copies remain.

Want to keep something? One star makes a note permanent.

• No account, no sign-up — open and write
• Stored on your device, with no account or cloud sync
• No ads, no tracking
• Minimal design, dark by default

Dayfly Pro (lifetime · one-time purchase):
• Multiple photos + video attachments (free: one photo per note)
• Per-note expiry — from 1 hour to 7 days, or forever
• Lock Screen widget with your latest note and time left
• Action Button & Siri quick capture (Control Center capture is free)
• Notes fade out as they near expiry
• Extra themes

Not a subscription. Buy once, yours for life.

Expired notes are hidden; stored data is cleaned up when the app is active. Device backups may include notes and attachments. Shared copies and originals in your photo library are not deleted when a Dayfly note expires.
