セキュリティOne is an app designed to protect your device from dangers and troubles. It detects and notifies you of potential risks when using websites, emails, phone calls, and Wi-Fi, ensuring your safety and security.

The app offers several key features:

(1) Virus Check: Scans your device and alerts you if any viruses are detected.

(2) Dangerous Site Check: Detects and notifies you of malicious sites, including fraudulent and fake websites.

(3) Dangerous Wi-Fi Check: Ensures the safety of your Wi-Fi connection and alerts you to any potential threats or unauthorized access.

(4) Nuisance Call Check: Detects and alerts you to nuisance calls, such as scams and aggressive solicitations, using the latest nuisance call number list provided by the police. You can even block unwanted calls by adding them to the block list.

(5) Nuisance Message Check: For users of the "+Message" service, the app automatically detects and categorizes nuisance emails into a separate folder. For users of "SoftBank Mail" and "Message," the app displays notifications for nuisance SMS messages.

Please note that the app utilizes the "User Assistance Function" to detect malware apps, dangerous sites, and display warning messages. The information collected by this function is limited to the app's purpose and does not include any other personal data.

セキュリティOne is available for Android devices and is free to download. However, there is a monthly fee of 440 yen for the service, which will be charged to your Google account. Please be aware that simply deleting the app does not cancel the service.
