Privacy Policy

Last updated: 2026-09-12Effective: 2026-11-12

M&W SOFT ("we") sets out below how we handle your information in the Miharu mobile app and the related website and services (together, "the Service").

We do not provide personally identifiable information to third parties, and we do not sell your usage data.

1. Information we collect

1.1 Information you entrust to us for monitoring

• The monitoring you set up (the URL to monitor, keywords, what to track, the check interval, notification settings and so on)
• The page content our servers retrieve, and the results of monitoring (records of what was detected, and the history of the values being tracked)
• For monitors with "Maintain Login" enabled, the information needed to keep the session on the monitored site

1.2 Information about account linking

If you link an account by signing in with Apple or Google, we obtain the account identifier and email address. We never obtain your password.

1.3 Device and notification information

• The device identifier needed to deliver push notifications
• Technical information such as the device and OS type and version, the app version, and the language setting

1.4 Information for support and improvement

• Feedback sent from within the app (anonymous; device and OS information is sent with it). What you send is retained by us as a record for handling enquiries
• App crash information, and statistics such as which features are used. Statistics are recorded together with an identifier that distinguishes the device or the account

1.5 Information about paid plans

The purchase and renewal status of a paid plan. Payment is made through the Apple App Store or Google Play, and we never obtain payment details such as credit card numbers.

1.6 Information about external notifications

Where you set up external notifications, the details of the destination (an email address, or the identifier of the destination within the service you connect).

2. How we use information

• Running the monitoring you set up, and notifying and displaying its results
• Sharing data across several devices through account linking
• Providing paid plans and managing their usage
• Investigating and fixing problems, and improving the Service
• Responding to your enquiries

3. Where information is stored, and for how long

Data for the Service is stored on cloud infrastructure we manage. The storage locations include servers outside Japan.

Monitoring results and retrieved page content are deleted automatically once a certain period has passed.

If you delete a monitor, its results are deleted with it and cannot be restored.

If you have not used the Service for a long time, the data we hold for you is deleted automatically once a period we determine has passed.

4. Disclosure to third parties and use of processors

Except where required by law, we do not provide personally identifiable information to third parties.

To provide the Service we use the services of external providers for cloud infrastructure, authentication, notification delivery and analytics, and entrust them with handling information to the extent needed to provide it.

Signing in to an account and paying for a plan are handled through the services of Apple and Google.

5. Personal AI integration (MCP)

If you connect a personal AI such as ChatGPT or Claude to the Service, that AI can read and write your monitoring settings and results within the scope you permit. A connection is established only by your explicit approval in the app, and you can remove it in the app at any time.

Once connected, the handling of the information passed to that AI is governed by the privacy policy of its provider. We are not responsible for how information is handled by the AI service you connect to.

6. External notifications

If you set up external notifications, monitoring results are sent to the destination you specify. How the information is handled at that destination is left to the provider of that service and to you.

7. Analytics and consent

To improve the app, we collect statistics on how features are used, using an external analytics service. We also collect app crash information in order to identify and fix the causes of problems. Neither is intended to identify you personally.

In the European Economic Area and other regions where this applies, the app shows a consent screen at launch, and we do not collect usage statistics without your consent. You can change or withdraw that consent at any time in the app settings. Crash information does not record your behaviour and is necessary for the Service to work properly, so it is collected whether or not consent is given.

On the official website (miharu-app.com) we use cookies for analytics. In the regions where this applies we show a consent banner, and we do not measure without your consent. You can change or withdraw that consent on the website at any time.

8. Your rights

You may ask us to disclose, correct, delete or stop using the information we hold about you.

You can delete the data we store from within the app, using the method in section 9. For any other request, please contact us at the address in section 11.

If you are in the European Economic Area or the United Kingdom, you may exercise the rights to data portability and to object, as provided by applicable law.

9. How to delete your data

• You can delete all of the data we hold for you by opening "Settings & Usage" in the app and choosing "Delete All Data". This is available whether or not you have linked an account. Deletion cannot be undone.
• To delete only an individual monitor and its results, delete that monitor in the app.
• Removing the app from your device does not delete the data we hold. Reinstall the app on the same device, or sign in with the same account if you have linked one, and your data will be restored; then use "Delete All Data".
• 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.

10. Changes to this policy

We may revise this policy in response to changes in the law or in the Service. If we make a significant change, we will give notice by posting it on this page or announcing it in the app.
