## What is Kekkai?

Can't open it, so you won't.

Kekkai puts a timed "barrier" in front of the apps you choose. Open a blocked app and a barrier screen appears; when your time is up, it lifts automatically. Step away from your phone with a system — a little friction — instead of willpower.

Who it's for
- You keep opening social apps or videos you'd rather not
- You want to focus during study, work, or before a deadline
- You want to stop late-night phone scrolling

What you can do
- Quick barrier: 15 min to 8 hours on the apps you pick
- Scheduled barrier: automatic by day and time (e.g. 11 pm–7 am for social apps)
- Deep Focus: a wait before you can lift it, to ride out the urge
- Records: times protected and focus minutes you've stacked up

Light and private
- No account. Fully on-device. Zero network.
- Even this app can't see which apps you chose — Apple's Screen Time keeps it private.
- No ads, no tracking.

Kekkai Pro
Deep Focus, 5 schedules, 3 preset slots, a custom shield message, and unlimited history. Yearly (7-day free trial), monthly, or a one-time purchase.

Note: This uses Apple's Screen Time (Family Controls) to manage your own device only. The barrier is friction — you can lift it anytime from Settings. Phone and emergency calls are never blocked.

Kekkai Pro (In-App Purchases)
- Yearly ¥2,980: includes a 7-day free trial. Unless canceled at least 24 hours before the trial ends, it automatically converts to a paid yearly subscription and ¥2,980 is charged to your Apple Account.
- Monthly ¥480: auto-renews.
- Lifetime (one-time) ¥5,980: a single payment, no auto-renewal.
Subscriptions auto-renew unless canceled at least 24 hours before the end of each period. You can cancel anytime in your App Store account settings.
