This Privacy Policy shall take effect as of December 02, 2025. This page is intended to inform all users who choose to use our Service about our policies regarding the collection, use, and disclosure of Personal Information.
If you choose to use our Service, you agree to the collection and use of information in accordance with this Policy. The Personal Information we collect is used solely to provide and improve the Service. Unless otherwise specified in this Privacy Policy, we will not use or share your information for any other purposes or with any third parties.
The terms used in this Privacy Policy shall have the same meanings as those in our Terms and Conditions, which are accessible within the "Purify Cleaner" app, unless otherwise defined in this Privacy Policy.
Important Permissions We Request
Depending on the context of your interactions with us, we may ask you to grant certain permissions to ensure the proper functioning of the app. You may opt out of these permissions at any time; however, please note that failing to grant these permissions may result in malfunctions of the app. The permissions we request are as follows:
Storage Permission
Read the contents of your device storage (including USB storage)
Modify or delete the contents of your device storage (including USB storage)
This permission is solely used to perform core cleaning functions such as junk file scanning and cache cleaning. We do not collect personal files (e.g., photos, documents, contacts) from your storage.
Optional Device Permissions
App List Access Permission: Used to identify redundant apps and duplicate installation packages to assist with app cleaning.
Approximate Location Permission (network-based, optional): Used only to optimize regional service experiences (e.g., adapting to local network environments). We do not collect precise location information.
1. What Information Do We Collect?
1.1 Personal Information
"Personal Information" refers to information that can identify you or another individual. We only collect Personal Information within the minimum scope necessary to provide the Service, including:
Location-related data (only if you grant location permission): Your device's network IP address and network-based approximate location, used to optimize service adaptation;
Log Data (automatically collected): Technical logs generated when you use the app, including device model, operating system version, app version, usage time, function operation records, and error logs. This data is used solely for troubleshooting and service optimization.
1.2 Non-Personal Information
"Non-Personal Information" refers to information that cannot directly or indirectly identify you. It will be anonymized after collection, including:
Basic device information: Hardware model, system version, unique device identifier (used only for device recognition, not linked to personal identity), and mobile network type (WiFi/cellular network);
Usage behavior statistics: Frequency of core function usage (e.g., number of cleaning sessions, scanning duration) and device performance-related data (e.g., memory usage, remaining storage space). This data is used solely to analyze service usage and optimize user experience.
1.3 Information Collected by Third-Party SDKs
To implement core functions and optimize the Service, we use the following third-party SDKs. The collection of information by these SDKs is subject to their respective privacy policies:
Security Scanning SDK (Trustlook Security): Collects only data related to app installation packages for malware detection. It does not collect Personal Information;
Data Analysis SDKs (Firebase/Google Analytics): Collect app usage logs and basic device information (after anonymization) to analyze service effectiveness and optimize product experience;
Advertising SDKs (Google Admob/Mintegral, etc.): Only if you agree to receive ads, these SDKs collect device advertising identifiers (IDFA/Android Advertising ID) to deliver personalized ads. You can disable ad tracking in your device settings.
2. How Do We Use the Collected Information?
2.1 Core Purposes of Use
Provide and maintain core app functions: Such as junk file cleaning, device acceleration, and malware scanning;
Optimize service experience: Adjust function adaptability (e.g., adapting to different system versions, optimizing cleaning algorithms) based on device information and usage behavior;
Troubleshoot and improve: Locate app errors, fix vulnerabilities, and enhance service stability using Log Data;
Optional personalized recommendations: If you agree, we may push relevant function guides or ads tailored to your needs based on Non-Personal Information. You can disable this feature at any time in the app settings.
2.2 Restrictions on Information Use
We will not use Personal Information for purposes not specified in this Policy;
We will not sell or rent any Personal Information to third parties;
All collected information will be retained only for the shortest period necessary to achieve the service purpose, after which it will be automatically deleted or anonymized.
3. Information Sharing and Disclosure
3.1 Third-Party Sharing
We will only share information with third parties in the following circumstances (and we have required all third parties to comply with confidentiality obligations):
To implement core functions: For example, providing app installation package data to the Security Scanning SDK, or providing anonymized device identifiers to Advertising SDKs (solely for ad delivery);
To comply with legal requirements: If we receive a valid notice from judicial authorities or regulatory agencies, we may disclose relevant information to comply with legal provisions.
