Frequently asked questions
Answers to the questions we hear most often about using Miharu and troubleshooting it.
Monitoring
Can I monitor all web pages?
Unfortunately, there may be limitations on accessing websites from monitoring tools like Miharu, or certain web page structures may not be compatible with monitoring.
We recommend trying our free trial to monitor actual web pages.
Especially when considering a Paid Plan, we recommend trying to monitor your desired web pages to ensure compatibility before subscribing.
What is the difference between Simple Mode and Advanced Mode?
The chosen operation mode affects how Miharu periodically monitors web pages.
In Simple Mode, Miharu accesses and monitors web pages using a simplified mechanism different from browsers like Safari. Due to this simplified mechanism, some web pages that rely on browser-generated content may not be monitored correctly, and the number of monitorable web pages may be limited compared to Advanced Mode.
In Advanced Mode, Miharu accesses and monitors web pages using a mechanism equivalent to Safari and other browsers. With this equivalent mechanism, Miharu can monitor a wider range of web pages, including those relying on browser-generated content.
However, depending on the web page structure, there may be cases where access is not possible in each operation mode. You can check whether a web page is accessible in each operation mode when adding monitorings in Miharu.
In Simple Mode, even if access is possible, the inability to generate the page may result in the inability to monitor the content correctly. Therefore, if both operation modes are available, we recommend selecting Advanced Mode.
Account and new devices
Can I transfer my Miharu data to a new device when I switch devices?
By setting up “Account Link” in the Miharu installed on your previous device before the device switch, you can transfer the data (watchlist, etc.) to the Miharu installed on your new device.
The data is associated with your account (Apple or Google), so you must set up “Account Link” on your previous device first, before the device switch.
We recommend setting up “Account Link” on your previous device before the device switch in order to prepare for future device switches.
I want to be able to monitor Miharu on my iPhone and also check it on my iPad. Is that possible?
By setting up “Account Link”, you can share data (such as watchlists) between Miharu installed on different devices.
At the same time, you will receive push notifications, including updates, on each device.
To share the monitoring from your iPhone to your iPad, please set up “Account Link” on the Miharu installed on your iPhone first, and then set it up on the Miharu installed on your iPad.
I want to delete the data Miharu has stored.
Open "Settings & Usage" in the app and choose "Delete All Data". This deletes everything stored, including your monitors, monitoring results, and notification and external notification settings. It works whether or not you have linked an account, and it cannot be undone.
Removing the app does not delete the stored data. Reinstall the app on the same device, or sign in with the same account if you have linked one, and your data is restored; then delete it.
If you have an active paid plan, deleting your data does not cancel the subscription. Cancel it in your Apple App Store or Google Play settings.

A monitored page was updated, but I didn’t receive a notification. (For iPhone / iPad)
Miharu detects changes to web pages on the server side and sends notifications. If a notification doesn’t arrive, please check the following in order.
1) Notifications are turned on for Miharu Open the Settings app → Notifications → Miharu, and make sure “Allow Notifications” is turned on.
2) Sounds and banners are turned on On the same screen, check that “Sounds”, “Banners”, “Lock Screen”, and “Notification Center” are enabled. If these are off, notifications may arrive without a sound or without appearing on screen.
3) A Focus mode isn’t silencing notifications Open Settings → Focus. If you use a mode such as “Do Not Disturb”, “Sleep”, “Work”, or “Reduce Interruptions”, make sure Miharu’s notifications are allowed. Adding Miharu to the allowed apps, or turning on “Time-Sensitive Notifications” for that Focus, helps notifications come through even during Focus.
4) Miharu isn’t in the Scheduled Summary If you use Settings → Notifications → Scheduled Summary, notifications from apps included in the summary are delivered at set times rather than immediately. To receive Miharu notifications right away, remove Miharu from the summary.
5) If you use an Apple Watch When your Apple Watch is on your wrist and your iPhone is locked, notifications may be delivered to the Apple Watch instead of appearing on the iPhone. Please also check the notifications on your Apple Watch.
6) Other Please also check the silent switch (mute) and the volume on your device. If the issue persists after checking all of the above, restarting your iPhone sometimes helps.
A monitored page was updated, but I didn’t receive a notification. (For Android)
Miharu detects changes on our servers and sends the notification to your device. If notifications do not arrive, please check the following in order.
1) Notifications are turned on Open Settings → Apps → Miharu → Notifications and check that notifications are allowed and that “Web Monitoring Alerts” is on.
2) Miharu is excluded from battery optimization This is by far the most common cause. To save power, Android restricts apps it considers unused. Open Settings → Apps → Miharu → App battery usage and choose “Unrestricted”. If you declined the “To receive notifications faster” prompt when you first opened Miharu, the app is still subject to battery optimization.
3) Do Not Disturb is not blocking it If you use Do Not Disturb, check that Miharu is allowed to notify you.
4) Data Saver is not limiting background data With Data Saver on, background data is limited and notifications can be delayed. Allow unrestricted data for Miharu, or try again on Wi-Fi.
5) Manufacturer power-saving features Xiaomi, OPPO, vivo, HUAWEI, Samsung and others add their own power saving and auto-start restrictions on top of Android. Allow Miharu to start automatically and exclude it from power saving.
6) Other In Settings → Apps → Miharu → Notifications → Web Monitoring Alerts, check that sound and vibration are on. If they are off, notifications arrive silently. If none of this helps, restarting the device sometimes resolves it.
The names and locations of these settings differ depending on your Android version and device manufacturer.
Where can I find the Webhook notification specification (data format, setup, etc.)?
The detailed specification for Webhook External Notifications is available in our dedicated “Webhook Integration Guide”.
The guide covers: - Setup - HTTP specification (method, headers, timeout) - Payload format (common fields, per-event details, sample JSON) - Idempotency and security - Integrations (Zapier / Make / n8n / your own server) - Limitations and troubleshooting
This feature is intended for developers and power users; you need to implement the receiving side (an endpoint that accepts HTTP POST and returns 2xx).
