1. Contact Support

Email kaisei@orochisystems.com for Kaisei support. The fastest way is from inside the App. Open Profile, tap the gear to open Settings, scroll to ABOUT at the foot of the page and tap Contact Us. This opens a mail whose subject already carries your Kaisei version, build number and iOS version, and nothing about you or your health is attached. We can help with recovery scores, the daily verdict, sleep, stress and vitals reads, Apple Health permissions, overnight refresh, Apple Watch behavior, notifications, widgets and complications, the journal and experiments, appearance worlds, Kaisei Pro, purchases and restores, exports, and privacy controls.

2. Quick Setup Checks

If Kaisei is not behaving as expected, first verify the following. - You are running the latest version of Kaisei on iPhone and Apple Watch. Your version is shown at the foot of Settings, under ABOUT. - You wore your Apple Watch to sleep so there is overnight data to read. - Kaisei has permission to read the relevant categories in the Apple Health app. - Notifications and Background App Refresh are enabled for Kaisei. - Your iPhone and Apple Watch are updated to supported OS versions.

3. "Calibrating" or a Score Near 50

In your first days, Kaisei may show a calibrating score near 50. This is intentional. With a thin baseline the App reports an honest, near neutral score rather than a confident but wrong extreme. As you accumulate nights of data, your baseline sharpens and your scores become more personal. Wearing your watch overnight is the fastest way to calibrate.

4. No Score in the Morning

If no recovery score appears, confirm you wore your Apple Watch overnight, that Kaisei has Apple Health permission for heart rate variability, resting heart rate, and sleep, and that Background App Refresh is enabled. If you did wear your watch, give it a few minutes to sync and open the App once so it can compute today's score. Kaisei waits a short while for a night that is still syncing from the watch before it shows a daytime number in its place. The morning result is kept in your history as it was. The score on Today is live: it keeps moving as your watch takes new readings through the day, and the line under the ring says whether it is still the morning number or has moved since. A watch worn only by day earns a Day score from daytime readings once enough of them have landed. Your watch also has to be tracking sleep. An iPhone sleep schedule on its own only records that you meant to be in bed, not that you slept, so Kaisei treats such a night as unmeasured. On your iPhone open the Watch app, choose Sleep, and turn on Track Sleep with Apple Watch. If the watch was off your wrist overnight, Kaisei does not invent a night. Today says that overnight heart data is missing and, once enough daytime readings have landed, shows a Day score labelled as one, with your daytime stress read running while the watch is on your wrist. You can turn on Watch reminder under Settings, DAILY RHYTHM, to get one evening cue to wear your watch to sleep. It is sent only after a night went unrecorded or when the watch has been off your wrist for six hours or more by the evening.

5. Health Permissions and Data

Kaisei reads Apple Health data on your device to compute your scores. You can review or change what Kaisei may read in the Apple Health app under Sharing, or in Settings under Kaisei. Restricting a category may limit or disable parts of the App. For example, removing sleep access affects the sleep read and the overnight components of recovery.

6. Apple Watch, Widgets, Complications, and the Lock Screen

If the watch app, a widget, or a complication looks out of date, open the iPhone app once so it can recompute and share the latest result, then refresh or add the widget or complication again. The watch and iPhone read the same shared local data, so surfaces update after the main app next runs. The morning glance on the Lock Screen and in the Dynamic Island can be turned on or off under Settings, DAILY RHYTHM. It dims once its day has passed and iOS removes it on its own schedule, so it may not disappear at midnight exactly; the next morning's refresh replaces it.

7. Notifications

Kaisei's reminders are set under Settings, DAILY RHYTHM. They are Morning recovery, Evening wind down, Watch reminder, Trend alerts, and Sunday letter. The Sunday letter note only arrives after a week with four or more scored mornings. If a reminder does not appear, confirm notification permission is enabled for Kaisei, check Focus modes and the notification summary, and confirm the reminder is switched on in the App. Delivery timing depends on Apple notification and background services.

8. Journal, Readings, and Experiments

Logging, backfilling past nights, and the countdowns that show how many nights a comparison still needs are free. A reading needs enough logged nights both with and without a behaviour before it can say anything, so a comparison that is still building shows how many nights are left. Finished readings and experiments are part of Kaisei Pro. Readings describe how your own logged behaviours line up with your own mornings. They are observations, not proof of cause.

9. Kaisei Pro, Purchases, and Restore

Kaisei Pro is billed through the App Store. The plans are an annual subscription with a 7 day free trial for eligible new subscribers, a monthly subscription, and a one time Lifetime purchase. Current United States prices are $29.99 per year, $7.99 per month, and $99.99 for Lifetime. The price for your region is shown in the App before you buy. - Pro did not unlock. Open Profile, tap the gear to open Settings, and under KAISEI PRO tap Restore purchases while signed in to the same Apple Account used to buy. Do the same after reinstalling or switching devices. - Manage or cancel. Open Profile, tap the gear to open Settings, and under KAISEI PRO tap Manage subscription, or open the Settings app on your iPhone, tap your name, tap Subscriptions, and select Kaisei. Cancel at least 24 hours before the renewal date. You keep Pro until the end of the period you paid for. - Free trial. You are not charged during the trial. If you have allowed notifications, Kaisei reminds you before it ends. Cancel at least 24 hours before the end of the trial if you do not want the annual plan to begin. - First year offer. After closing the upgrade page, some new subscribers are shown a reduced first year once, for example $19.99. It is charged on the day you accept, has no free trial, and renews at the standard annual price after the first year unless you cancel. It is shown only once and does not come back. - Lifetime. Lifetime is a one time unlock, not a subscription. If you buy Lifetime while holding a subscription, cancel the subscription yourself in your App Store account, because Apple does not cancel it for you. - Family Sharing. Kaisei Pro purchases are not currently shared through Family Sharing. - Billing and refunds. Apple processes all payments. For billing questions or a refund request, visit https://reportaproblem.apple.com or contact Apple Support.

10. Appearance and Worlds

Appearance lives under Settings. Some worlds are open to everyone, some are earned through milestones on your Profile, and six are part of Kaisei Pro. A locked world shows a small lock. A lock with PRO beside it belongs to Kaisei Pro, and a lock on its own names the milestone that earns it. The face can be set to System, Day, or Night, where System follows your iPhone's appearance setting, and one Motion switch turns the living backgrounds on or off.

11. Language

Kaisei is available in English, German, Spanish, French, Japanese, Korean, and Simplified Chinese. You can choose the App's language under Settings, YOU. System Default follows your iPhone.

12. iCloud Backup

Under Settings, DATA & PRIVACY, Kaisei can keep your streak, your tag history, and your custom tag names in your own private iCloud so a new iPhone or a reinstall can restore them. Your health readings and scores are never part of this backup, and the Medication tag never leaves your iPhone. Turning the switch off deletes the backup from iCloud. If your streak or tags do not restore, confirm you are signed in to the same Apple Account and that iCloud is available, then open the App and allow a moment for the restore.

13. Export and Deletion

Under Settings, DATA & PRIVACY, Export my data saves everything as one readable file. Protect exported files after you save or share them. Delete all my data erases your history, tags, feelings, experiments, streak, and profile from your iPhone, your paired Apple Watch, and your iCloud backup, and it cannot be undone. Samples in Apple Health stay where they are, including any mindful minutes or Watch workouts you chose to save there. Deleting your data or the App does not cancel a subscription.

14. What to Include in Your Email

Contact Us in the App fills in your Kaisei version, build, and iOS version for you. Please add your iPhone and Apple Watch models, your watchOS version, whether you wore your watch overnight, which Health permissions are granted, which part of the App is involved, and a short description of what you expected and what happened instead.

15. Privacy and Safety Note

Do not send passwords, Apple Account credentials, or other secrets. If you share screenshots of your health data, redact anything personal first. Kaisei is a wellness and fitness tool, not a medical device. For any health concern, consult a qualified healthcare professional.
