We will follow the principles of legality, legitimacy, and necessity to collect and use your personal information for the purposes described in this policy. If your personal information is used for purposes other than those stated in this policy, we will inform you in a reasonable manner and obtain your consent.
When you use this Product, we need to collect and use your personal information in the following two circumstances:
1.To support and realize the basic business functions of this Product (part or all of the business functions), you need to authorize us to collect and use your necessary personal information.
2.To enrich our products and enhance your experience, in addition to providing basic business functions, we will also offer extended business functions. Such functions require the collection and use of corresponding personal information. If you refuse to provide it, you will not be able to use the extended functions or enjoy the intended experience, but this will not affect your use of the basic business functions of this Product.
If you refuse us to collect any necessary personal information, we will not be able to provide you with any functions or services of this Product, including basic business functions.
1.Mobile Album Cleaning Service
This function includes similar photo recognition, photo cleaning, photo compression, and video compression. To implement this function, you need to grant album permissions. After authorization, we will identify similar photos and dark photos on your mobile phone through local analysis, enabling you to delete duplicate or blurry photos, clean up albums, compress videos, and quickly free up storage space. We will not upload photos or video information from your mobile phone album to the Chenzhi server. You can navigate to "Me → Permission Management" in this Product or directly enter your mobile phone's local "Settings → Clean Up" to disable and withdraw the "Photo" authorization. After withdrawing the authorization, we will no longer be able to provide this service or obtain any relevant information from you, but it will not affect your use of other functional services.
2.Private Space Services
This function provides privacy protection for recordings, notes, password books, and album encryption. It requires you to grant album permissions and microphone permissions. After obtaining these permissions, when setting up an encrypted object, you need to add the photos, recordings, notes, password books, and passwords you want to encrypt and protect to the "Privacy Space." The confidential content and passwords you set are stored only locally and will not be uploaded to the server or shared with third parties. You can manage your privacy password through "Privacy Space → Settings."
At the same time, you can turn on or off fingerprint or Face ID unlocking to protect your privacy space. After enabling fingerprint or Face ID unlocking, Clean Up calls the iOS system's built-in fingerprint or Face ID unlocking system. The iOS system will read your fingerprint or facial data, complete the verification, and return the verification result to Clean Up. We will not read, re-acquire, or store your fingerprint or Face ID data.
1.Address Book Optimization Services
This function can merge and analyze incomplete contacts in the address book to ensure its integrity. To implement this function, you need to grant address book reading permission. After authorization, address book optimization can be realized through this function.
2.Network Speed Measurement Services
This function can help you detect your mobile phone's network speed (latency, upload speed, download speed). To implement this function, we will directly detect your device's network environment through the mobile phone system's public interface. During the implementation of this function, we will not obtain any of your personal information.
1.Calendar Cleaning Services
This function can determine whether items in your calendar are harassing advertisements or spam based on local rules and provides you with cleaning suggestions and ways to avoid calendar harassment and fraud. When you turn on this function, you need to authorize two local permissions: "Access Calendar" and "Access Reminders" to use calendar reminder settings and expired calendar cleaning functions. You can enable or disable these two authorizations through "Me → Permission Management" in this Product or directly enter your mobile phone's local "Settings → Clean Up." After withdrawing the authorization, this function will be disabled. We will no longer obtain any relevant information from you or provide this service, but it will not affect your use of other functional services.
During service provision, [Clean Up] will call some of your device permissions. This section summarizes all system permissions involved in the above (I) and (II) for full transparency:
Permission Name | Functional Scenario | Purpose of Use | Can It Be Closed? |
Address Book Permissions | Address Book Optimization | Optimize mobile contacts; merge and analyze incomplete contacts | Yes |
Calendar Permissions | Calendar Cleaning | Clean up expired calendar items | Yes |
Album Permissions | Mobile Album Cleaning and Video Compression | Clean up and detect photos or videos on the mobile phone | Yes |
Camera Permissions | Taking Photos | Take photos and save them to the Privacy Space | Yes |
To ensure the normal implementation of our functions and services, we will call corresponding necessary permissions or non-essential permissions (which help improve service experience but do not affect core function usage if not granted) based on specific usage scenarios. We will ask for your consent via a pop-up window before calling. Sensitive permissions are disabled by default and will only be authorized to us after your explicit consent. Please note that obtaining a specific sensitive permission does not mean we will necessarily collect your relevant information; even if we have obtained sensitive permissions, we will only collect information when necessary and in accordance with this policy.
You can choose to turn off some or all permissions in your device's settings to refuse [Clean Up] from collecting corresponding personal information. The display and disabling methods of permissions may vary across devices; please refer to the instructions or guidelines of the device and system developers for details. Please note that enabling any permission means you authorize us to collect and use relevant personal information to provide corresponding services. Disabling any permission means you revoke the authorization; we will no longer collect or use relevant personal information based on that permission and will stop providing the corresponding service. However, disabling permissions will not affect the collection and use of information completed based on your prior authorization.
