## What is Smartphone Sentinel?

The product mainly provides a security protection function for adventurers and women on the go. We create a guard mechanism through various security protection functions. You can protect yourself through the sound disguise and anti wolf alarm of this product. At the same time, we provide some cleaning functions for mobile phone memory to protect your phone storage space.

Function Introduction:
——Album cleaning
We use artificial intelligence technology to help you quickly scan, identify, and delete duplicate photos, blurry photos, and other unwanted images. We will categorize your albums for you to easily organize and free up storage space on your device.

——Address book cleaning
We can identify and merge duplicate contacts, and correct erroneous information. This helps keep your address book clean and efficient, ensuring that you can quickly find the people you need to contact.

——Calendar Cleanup
The calendar cleaning function will scan your calendar entries, delete expired events, remind you of upcoming events, and merge duplicate entries. This not only helps you better manage your time, but also avoids schedule conflicts and improves daily efficiency.

——Sound camouflage
The voice disguise function can change your voice, such as simulating different genders, ages, or tones. We hope that when you are alone at home or outside, you can create the illusion of someone around you or someone approaching, so that criminals can dispel their thoughts of doing bad things. Using it will be useful.

——Account and Password Management Book
We will provide a secure privacy space that can securely store and manage your various accounts and passwords, while supporting the filling of login information and generating strong passwords for each account. This not only prevents you from forgetting your password, but also further enhances your network security.

——Subscription Notification Management
The subscription notification management function can centrally manage all your subscription notifications, allowing you to customize the reminder time and notify you before the corresponding time point. Through it, you will not forget to cancel some unused software renewal services, saving expenses.

——Wolf proof alarm sound
In emergency situations, using this function can emit a high decibel alarm sound by pressing the button, attracting the attention of people around, increasing personal safety, and making it easier to obtain help and support. At the same time, we provide the flashing method of the International SOS flash. When you are in danger and there is no signal contact, calling for help to people in the distance through the flash may be a good way!

Regarding the membership function, you can use the trial function of this product to experience the service. After the trial is over, this product will charge a corresponding fee. You can turn off the service through the APPID settings management. Please remember to turn it off in advance, otherwise the membership service will be automatically renewed
