## What is Hibiwa?

One card a day. To one close person.
It won't vanish in a feed — it's kept forever in your shared box.
No notifications every minute. No likes. No algorithm. Just the two of you.

WHAT HIBIWA IS
Hibiwa (日々和 — "daily harmony") is an app for leaving exactly one card a day to exactly one close person. Not chat. Not social. Not a streak. Not a journal for yourself (unless you want it to be — there's a "for yourself" mode too). Just a short, daily gesture — two sentences, one memory, one warm touch — kept forever in your shared keepsake box.

WHY ONE
Because the daily measure forces presence. You don't write whenever — you write when you actually have something to say. The same thought that could scatter into twenty messages distills into one sentence. It's the difference between a letter and a text.

HOW IT WORKS
• No new account — Hibiwa uses your iCloud account (no signup, no password, no email).
• Send your loved one an iMessage invite link.
• Leave one short card per day. The limit resets at dawn (5:00 local).
• They see your card under a soft mist — a long press reveals it.
• Warm trace — a double tap, a gentle haptic on their phone. No words.
• Together now — a soft dot lights up when you're both in the app at the same moment.
• Sealed envelope — a card for a hard day, for when they miss you. Opened only when they choose.
• Keepsake box — every card kept, like a real lacquered chest.
• Apple Watch — glance at the latest card on your wrist; feel a warm glow when your person reaches out.

24 SEASONS
Hibiwa breathes to the rhythm of the 24 Japanese microseasons (sekki). Every two weeks the accent, the prompt, the color shifts. Spring's awakening, summer's solstice, autumn's clearing — the app changes with the season you are living in.

QUIET AND PRIVATE
• No servers. Your cards travel directly through Apple iCloud — Hibiwa has no access.
• No trackers. No ads. No third-party analytics.
• Privacy Manifest 2026 compliant.
• Your relationship is yours. Our work is to protect it.

HIBIWA+
A Hibiwa+ subscription unlocks your full keepsake box (free tier keeps 7 days), five sealed envelopes at a time, unlimited "second sides" (time capsules), monthly and yearly digests with a Japanese book-layout PDF export, the full pool of 24-sekki prompts, and premium widgets.

• Family Sharing — your whole Apple Family on one subscription
• 3% of revenue donated to family-crisis and mental-health organizations

WHO IT'S FOR
For long-term couples who want to tend daily intimacy without messaging-app overwhelm. For a mother and a son in another city. For a grandmother and a grandchild who want to leave something that outlasts years. For siblings scattered across the world. For your closest friend. For yourself — a "for yourself" mode lets you write to your future self.

Not for everyone. Not for every day. For the days when you want to say "I remember you."
