2. Information We Collect
To implement the core garbage cleaning function, ensure service stability, and optimize user experience, we only collect information that is "necessary to achieve the intended purposes" and do not collect irrelevant personal data. The specific information collected includes:
(1) Device-Related Information
Necessary Device Identifiers: To adapt to different devices and ensure the accurate operation of the cleaning function, we collect your device ID (e.g., Android ID), which is only used for unique device identification and is not linked to personal identity information.
Basic Device Parameters: Including device model, operating system version, screen resolution, available storage capacity, and running memory size. This information is used to ensure the compatibility and stability of this App across different hardware configurations and to prevent functional failures caused by device incompatibility.
(2) App Usage Information
Function Usage Data: Records of your operational behaviors when using this App, such as the usage frequency of functions like "garbage scanning," "large file cleaning," and "app management," as well as the size and type of files cleaned in a single operation.
Diagnostic and Fault Data: When this App encounters issues such as crashes or freezes, anonymized fault logs (excluding personal identity information) are automatically collected. These logs are used to identify and fix software vulnerabilities and improve service reliability.
(3) Other Optional Information
Only with your active consent may we collect feedback information you provide, such as:
(4) Information Explicitly Not Collected
We will never collect information about children (i.e., any personal information of minors under the age of 13). If we discover that we have inadvertently collected information about a minor, we will immediately terminate the service, delete all relevant data within 7 working days, and will not use such data for any other purposes.
3. How We Use Your Information
We strictly adhere to the "purpose limitation" principle, and the collected information is only used for the following legitimate purposes, with no use beyond the specified scope:
(1) Provision of Core Services
Implementation of Garbage Cleaning Function: Determine the device storage structure based on device information and identify "garbage files" (e.g., expired files, useless installation packages) based on usage information to perform scanning and cleaning operations, helping you clear garbage files from your device.
Personalized Service Optimization: Based on your usage habits (e.g., frequently used cleaning functions, cleaning frequency), push tailored optimization suggestions (such as reminders for "regular garbage cleaning") to enhance operational convenience.
(2) Service Improvement and Optimization
Function Iteration: By analyzing usage data, identify high-frequency user needs (e.g., high usage rate of the "large file cleaning" function) and prioritize the optimization or addition of relevant functions.
Performance Enhancement: Based on device parameters and fault logs, fix compatibility issues (e.g., incomplete cleaning on specific device models) and optimize the App’s operating speed and stability.
(3) Customer Support
When you provide feedback via email, we will use the device information and usage scenarios you provide (e.g., "insufficient storage space still prompted after cleaning") to quickly identify the cause of the problem and provide an accurate solution.
(4) Legal Compliance and Rights Protection
Where required by laws and regulations, your information may be used to:
4. Rules for Data Sharing and Transfer
We strictly adhere to the "minimum necessity" and "confidentiality obligation" principles and will never sell or rent your personal information to third parties for marketing purposes. Your information may be shared or transferred only in the following circumstances:

Only to achieve the purposes stated in this Policy will we share information with third-party partners that provide technical support for us. We will sign a Data Processing Confidentiality Agreement with them and require them to comply with the following obligations:
Common scenarios for sharing include:
Server Hosting Service Providers: Share anonymized copies of device information and usage data to ensure the stable operation of the App server (e.g., traffic load balancing).
Data Analysis Service Providers: Share usage data that does not contain personal identity (e.g., statistics on function usage rates) to generate user experience analysis reports and assist us in optimizing functions.
(2) Sharing Required by Law
We may disclose your information to competent authorities in the following legal circumstances:
Compliance with applicable laws, regulations, or administrative orders;
Response to legitimate investigations or official requests from government agencies (e.g., public security organs, market supervision departments);
Protection of the legitimate rights and interests of this App, its users, or the public (e.g., responding to activities involving fraud or endangering network security).
(3) Data Transfer in Business Transfers
If we undergo changes such as business mergers, acquisitions, or asset sales, your personal information may be transferred to the new entity as part of the transaction assets. However, we will require the new entity to continue complying with all terms of this Privacy Policy; if there are major changes to the Policy terms, we will notify you via App pop-ups or other means and obtain your consent.
5. Your Statutory Rights
Pursuant to applicable privacy laws and regulations (including but not limited to CCPA, VCDPA, and GDPR), you are legally entitled to the following data rights, and we will facilitate the exercise of these rights for you:
(1) Basic Rights (Applicable to All Users)
Right to Know: You have the right to know whether we collect, use, or share your personal information, as well as the categories of collected information, purposes of use, and recipients of shared information (detailed explanations may be obtained by reviewing this Policy or contacting customer service).
Right of Access: You have the right to request us to provide a copy of your personal information stored in our system (e.g., feedback records you submitted, device information).

Right to Withdraw Authorization: You may withdraw authorization for permissions such as "storage" and "device information access" through your device’s system settings (e.g., "App Management - Clever Clean Assistant - Permissions"). Withdrawal of authorization may affect the use of certain functions (e.g., inability to scan stored files).
Right to File a Complaint: If you believe that our information processing practices infringe upon your legitimate rights and interests, you have the right to file a complaint with the local data protection authority (e.g., the U.S. Federal Trade Commission (FTC), EU data protection authorities).
(2) Additional Rights for California Users (Pursuant to CCPA)
In addition to the above basic rights, residents of California (as defined by CCPA) are entitled to the following additional rights:
Right to Request Disclosure: You have the right to request us to provide, free of charge, once per year, "the categories of your personal information collected in the past 12 months, their sources, purposes of use, and the categories of information shared with third parties and the names of such third parties."
Right to Opt-Out: If we engage in "personal information sales" in the future (we do not currently engage in such activities), you have the right to opt out; even in cases involving information sharing, you may request to stop sharing by contacting customer service.

Right to Object to Processing: If we process your information based on "legitimate interests," you have the right to object to such processing. We will review your objection and provide feedback within 15 working days (if the objection is valid, we will cease processing).
(4) Additional Rights for EU Users (Pursuant to GDPR)
In addition to the above basic rights, residents within the European Union (referred to as "data subjects" as defined by GDPR) are entitled to the following exclusive rights in accordance with the General Data Protection Regulation (GDPR):
Right to Obtain Details of Data Processing: You have the right to request us to explicitly inform you whether your personal information is being processed; if processing is taking place, you are entitled to detailed information about the purposes of processing, the legal basis for processing (e.g., "obtaining your consent," "performing a contractual obligation," "based on legitimate interests"), the specific categories of personal information, the recipients of the information (especially recipients outside the EU), and the retention period of the information (if there is no fixed period, the criteria for determining the period shall be explained).

Right to Object to Automated Decision-Making and Profiling: If we make decisions about your personal information through an automated system (without human intervention) (e.g., determining your service usage rights based on data analysis), and such decisions may have a legal effect on you or significantly affect you, you have the right to object to such decisions. You also have the right to request us to re-review the decision result through human intervention, explain the basis for the decision, and obtain an opportunity for reassessment. If profiling (assessing your personal characteristics through information analysis) is conducted based on "legitimate interests" or "performance of a contract," you also have the right to object.
Right to Withdraw Consent Immediately: If you previously authorized us to process your personal information based on "consent," you have the right to withdraw such consent at any time, and the withdrawal shall have retrospective effect (after withdrawal, we shall no longer process the information based on the original consent; the information already processed shall be properly disposed of in accordance with legal requirements, unless otherwise specified by law). The method for withdrawing consent shall be as convenient as the method for granting consent, and you may submit a withdrawal request directly via email or through the in-App settings (if available).
Right to Object to Cross-Border Data Transfers: If we need to transfer your personal information to a recipient outside the EU (e.g., an affiliated company in a non-EU region), and that region has not been recognized by the European Commission as having an "adequate level of data protection," you have the right to object to such transfer. We shall explain to you the supplementary measures adopted to ensure data security (e.g., signing EU Standard Contractual Clauses, adopting Binding Corporate Rules). If you still object to the supplementary measures, you may further file a complaint with a data protection authority within the EU.
