Monitor alerts are designed to notify monitoring users when medication status changes. When enabled, updates are delivered per linked person preference.
⚠️ Points
The Monitor tab is view-only. You cannot record doses on behalf of others.
📊 Dose-slot display consistency
Monitor cards show one slot per expected dose for each day. Slots are shown as taken time, missed (✕), or pending (—) based on that specific day's expected count.
🔒 Refresh safety guard
Manual refresh on the Monitor page is limited to once every 8 seconds. If you refresh repeatedly, a wait countdown is shown. This prevents accidental refresh spam and keeps monitoring checks stable.
Regenerate shared code

Tap "Regenerate code" to issue a new code. Share the new code with your monitor, since the old code is immediately invalid.

⏱️ Regeneration cooldown
To reduce abuse/spam, shared-code regeneration is server-throttled. If regeneration is attempted 5 times within 10 minutes, a 30-minute cooldown is applied. During cooldown, regeneration is temporarily disabled and a countdown is shown.
⚠️ About privacy and safety
Anyone with the shared code can view your medication records at any time. Share it only with trusted supporters. If you want to stop access, regenerate the code. Those who were viewing with the old code will no longer be able to view it.
🔒 Biometric protection
If biometric authentication (Face ID / Touch ID) is enabled in Settings under Account Protection, the following actions require authentication before they proceed.
  • Sharing via Quick share icons or More (when biometric protection is on)
  • Regenerating your share code
  • Viewing your Recovery Key
If authentication is cancelled or fails, the action will not proceed.

How to subscribe to Premium
  1. From the Settings tab, open the premium card to show the paywall.
  2. If you are returning after reinstall/device change, recover your account first in Settings -> Account protection (Apple or Recovery ID + key).
  3. For a new subscription, choose "Start monthly ¥400" or "Start annual ¥3,200".
  4. After purchase confirmation, Premium features unlock immediately.
How device setup works after Premium purchase

After purchase confirmation, a Device setup window opens. This setup decides which cloud-backed features you want to enable on this device.

Settings account-protection setup screen
Settings: account protection and recovery setup
  1. A single cloud toggle appears first: Cloud features (sharing / account protection) (default is OFF for first setup).
  2. If it remains OFF and you press "Complete with these settings (recovery disabled)", setup finishes immediately. Premium stays active, but cloud-backed sharing and account-protection recovery remain disabled.
  3. If you turn it ON, cloud-backed sharing and account-protection recovery features are both enabled.
  4. You can change this later in Settings -> Support.
ℹ️ Consent and cloud behaviour
Turning this cloud toggle ON counts as consent for cloud health-data processing used by sharing and account protection. Turning it OFF withdraws consent and pauses cloud-backed sharing/account-protection flows. Local medication logging on your device continues as normal.
How to cancel your subscription

Cancellation and plan changes are managed from your store subscription settings (App Store / Google Play).

⚠️ About data after cancellation
Even if you cancel your subscription, your previous medication data will not be deleted. Your data is stored on your device, so you can cancel with confidence. If you re-register, you can use all premium features again.
What is Account Protection?

Your premium status and sharing-owner authority are stored in a protected area on your device. If you change devices or reinstall the app, you will need to recover this information. It is strongly recommended to set up account protection before you need it.

There are platform-specific account-linking methods plus a shared recovery fallback:

⚠️ Invalid attempt handling
If Recovery ID/Key does not match, the app shows Invalid attempt and asks you to reconfirm your ID/Key pair and try again. Invalid attempts are counted (`x/5`), and 5 invalid attempts within 10 minutes trigger a 30-minute cooldown. During cooldown, recovery input is disabled until the timer ends.
What happens during device transfer (auto-reset)

After recovery completes on the new device, the old device is designed to reset to a new-user state automatically. In normal use, you should not need extra manual old-device control actions.

⚠️ Important
Important recovery/protection actions are guarded by biometric authentication (Face ID / Touch ID) or your device passcode. If authentication is cancelled or fails, the action is not performed.
How to recover after reinstall or device change
  1. On the new device, first confirm premium status, then open Settings -> Account protection.
  2. Recover with the same Apple account on iPhone or the same Google account on Android.
  3. If platform account recovery is unavailable, restore with Recovery ID + Recovery key.
  4. After recovery, premium status, sharing-owner authority, and medicine data are applied on the new device. The old device returns to new-user state automatically.

10. Scenarios and troubleshooting

Common use scenarios
Troubleshooting quick paths
Owner cannot load/see a shared code
In Settings -> Share my code, press Retry first.
If it still fails, follow the in-app guidance and recover your existing account from Account protection (Apple/Google or Recovery ID + key), then retry.
Monitor shows: "This share code cannot be confirmed at this time. Please try later."
Check the entered code, wait a few seconds, and try again.
If it still fails, ask the owner to re-share the latest code (after regeneration, previous codes are invalid).
If repeated invalid entries trigger a cooldown, wait for the countdown to finish before trying again.
Recovery shows: "Invalid attempt"
Reconfirm your Recovery ID + Recovery key pair and try again.
The app shows invalid attempts (`x/5`). At 5 invalid attempts within 10 minutes, recovery is locked for 30 minutes and the input field remains disabled until cooldown ends.
Monitor updates look delayed or partially stale
Use manual refresh on the Monitor page (8-second cooldown).
If one refresh does not catch up, wait 10-20 seconds and refresh again. A follow-up reconcile check may need one extra cycle to complete.
Old device does not look reset after transfer
After successful recovery on the new device, the old device should reset to a new-user state automatically.
If it appears stale, restart the app once on the old device so it can reload the latest session state.
Billing continues after in-app account deletion
In-app account deletion does not auto-cancel your App Store/Google Play subscription.
Cancel separately in your store subscription settings to stop billing.

11. FAQ

What if you press the wrong medicine?
If it is within 30 minutes of recording, an "Undo" button appears. Tap "Undo" to cancel the latest record. After 30 minutes, undo is no longer available.
Will my data be deleted if I delete the app?
If account protection is not configured, deleting the app removes local data. If account protection is configured, encrypted backup restore can recover medication definitions, dose logs, and monitor-list entries (code, display name, added time).
Is there a fee to enter someone’s shared code?
No. Entering a shared code to monitor records is free. Premium is required for the code owner who issues "Share my code".
Will my data be lost if I cancel my subscription?
It won't disappear. Data remains on your device. Re-registering will give you access to all premium features again.
Where are the photos saved?
Photos are only stored on your device. We do not send any information to external servers. Please note that if you delete the app, your photos will also be deleted.
Can I transfer my data when changing models?
Yes. Use Settings -> Account protection to recover on your new device. Use Apple recovery on iPhone, Google recovery on Android, or Recovery ID + Recovery key if needed. After recovery completes, premium status, sharing-owner authority, and medicine data are applied on the new device.
What if someone you don't know sees your shared code?
Once you press "Regenerate code", the old code is invalid immediately. Those who had the old code will no longer be able to view their medication records. Share your new code with a trusted supporter.
How often can I refresh the Monitor page?
Manual refresh is limited to once every 8 seconds. While waiting, the button shows the remaining seconds. This safeguard reduces burst traffic and temporary sync errors, and helps keep monitor status checks stable.
Can I receive notifications for multiple medications at different times?
Yes. You can set notification time individually for each registered medicine. In Premium, you can also set multiple reminders per day (up to 12) for one medicine.
Can I change the name of my medication later?
Yes. In the Settings tab, tap the pencil icon next to the medicine. Edit the name, then tap "Save".
I want to remove my medication, what should I do?
In the Settings tab, tap the trash icon next to the medicine. Confirm deletion to remove that medicine and its related records.

12. Privacy policy

Thank you for using Kusuri Memo (hereinafter referred to as "this application"). This Privacy Policy describes how we collect, use and protect your information.

1. Information we collect

This app stores the following information locally on your device:

For normal free use, medication content and dose history are managed on your device. If server-backed features are enabled, only the minimum data needed for those features is sent.

2. About server-backed features

When using account-protection restore or Monitoring sharing, the following information can be sent to Supabase (database service):

This information is used only for monitoring sharing and not for any other purpose. Backup payloads are used only for restore/transfer safety. Photo data is not sent to an external server.

Internal identifiers or state needed for subscription coordination, monitoring sharing, or account-protection features may also be created or stored server-side. These do not include your medication photos or the medication-content payload itself.

For shared data continuity and disaster recovery, server side data is mirrored to a second database. The standby project is used for recovery operations and follows the same access-control model.

The production database is hosted in Japan (Tokyo region) on Supabase.

3. Third Party Services

This app uses the following third party services:

RevenueCat

Privacy policy →
Sentry
Used for crash and diagnostic reports to detect and improve app defects. Reports may include technical identifiers (for example app-instance or device context) needed to investigate failures, and are not used for advertising tracking.
Privacy policy →

This app does not use advertising SDKs or third-party analytics SDKs. If we add anonymous first-party usage metrics in a future release, they will be limited to coarse product metrics that do not include medication-content payloads, and this policy will be updated before release.

6. About photo data

Medication photos are only stored on your device. We do not send, upload, or share any photo data to external servers.

7. Security
