Phonebook Navi's information collection mechanism uses AI analysis technology to collect, analyze, register, and block signals provided by tens of millions of users in real time.

Even compared to paid apps provided by communication carriers, Phonebook Navi uses an overwhelming amount of information to make highly accurate decisions. I think you will be surprised at the accuracy of the judgment.

To comply with the latest Google Play policies, you must set Contacts Navigation as a caller ID/nuisance call app on Android 10 or later.

By doing so, the caller ID display and block function will work.

Even incoming calls received from a landline can be forwarded to a mobile phone, making it possible to identify the caller.

*Please transfer to a mobile phone that has Phonebook Navi installed.

By using this method to handle incoming calls from landlines, you can block fraudulent calls and nuisance calls.

For households with elderly people, we strongly recommend setting up landline phone forwarding, as this is a powerful security measure.

You can stop pop-ups from displaying by turning off both "Display information when receiving a call" and "Display information when making a call" from the settings screen.

This operation will stop the foreground service.

Telnavi Engineer TEAM

*Calls made using data communication are not received using a telephone line, so the pop-up display will not work when receiving a call. If you are using some services such as Rakuten Link or LINEMO that make voice calls using data communication, the incoming call display cannot be displayed.

[About access to contacts]

Phonebook Navi does not send contact information to outside parties.

If the incoming number is registered as a contact, it will be used only on the device to prevent the call from being blocked.

Current Google app reviews are very strict, and there are particularly strict rules regarding the handling of privacy data.

If your app requests unnecessary permissions or does not handle personal information appropriately within the app, it will not pass the review and will not be published.

The phonebook navigation app is published in compliance with Google developer policies.

Please check that the free version works before purchasing the paid version. [Refunds cannot be made after purchase]
