Effective as of July 15, 2026
Your privacy is important to us. This document describes how Cleaner & Guard (referred to herein as "the Application," "we," "us," or "our") collects, uses, and safeguards information when you download and interact with our mobile application and any associated services accessible via the Google Play Store (together, the "Platform"). Please read this Privacy Policy ("Policy") carefully.
By installing or continuing to use the Application, you confirm that you have reviewed and agree to the practices outlined in this Policy.
To ensure the Application functions correctly and to adapt the experience to your specific device, we automatically receive certain technical data points when you engage with the Application. The exact set of data depends on your device configuration, the features you activate, and your privacy settings, but may encompass:
SDK, API, and script version identifiers; IP address; platform type; request time stamps; app version and bundle identifier; distribution source; a unique device-resident identifier; device make and model; OS version; locale and language settings; time zone; connectivity type (mobile data, Wi-Fi, VPN, etc.); CPU and battery metrics; screen dimensions; memory and storage statistics; mobile carrier and SIM country code; Google Play release track; ad-serving configuration data; advertising network and placement IDs; screen pixel width and height; developer mode flag; and ADB debugging status.
We also keep records linked to your device's Android ID, which enables us to correlate ad-related events attributable to your device over multiple sessions. For the purposes of this Policy, the Android ID is treated as personal data.
We record how you navigate and interact with the Application, including:
Tap/click counts, screen sequences and page-view paths, dwell time per screen, request timestamps, app-open counts, and which features or pages you access.
Whether specific permissions have been granted or denied.
Functional status of app features (e.g., whether a feature operated successfully).
The Application's package name.
The date and time of your initial app launch.
Application brand/build variant identifier.
Network reachability state from within the app.
A Firebase-generated device token.
Device model designation.
SIM-derived country code.
Device language configuration.
Cookies that our advertising collaborators may place or access.
This usage information is disclosed exclusively to approved analytics service providers — specifically Adjust, Google Analytics, Google Firebase, and Snowball — and only for the purpose of helping us comprehend and enhance the product. We do not commercialize this data, nor do we employ it for any objective beyond refining the Application and the effectiveness of our advertising.
The Application incorporates software development kits (SDKs) supplied by external partners. These SDKs may autonomously gather:
Your Google Advertising Identifier.
Approximate demographic indicators (e.g., inferred from your IP address).
Anti-fraud signals (including indicators that help detect invalid ad clicks).
Device-level details (model, technical attributes, country).
Data utilized for ad serving, campaign measurement, and analytics.
Cookie-based data, which advertising networks may read or write.
After these external parties collect such information, it falls under their respective privacy frameworks — not this Policy — and we do not exercise authority over their subsequent handling. Our SDK ecosystem comprises analytics vendors (Adjust, Google Analytics, Google Firebase, and Snowball). Direct URLs to each partner's own privacy documentation appear in Section G below.
Cleaner & Guard accesses your device's Android advertising ID exclusively for the purpose of personalizing the advertisements displayed to you and supporting related ad-performance analytics. This identifier is designed to be anonymous — standing alone, it does not enable identification of you as an individual, and it is not associated with any permanent device identifier or other personally identifiable records.
When you initiate direct communication with us — for instance, via a customer support inquiry, a feedback submission, or a survey response — we receive whatever information you choose to share, which may include your email address and the body of your message or survey answers.
We process the information necessary to:
Grant you access to and enable your use of the Application's capabilities.
Maintain the operational stability of the underlying platform.
Carry out specific actions you ask us to perform.
We have a legitimate interest in leveraging collected data to:
Continuously update and evolve the Application.
Tailor and enhance your in-app experience.
Administer our ongoing relationship with you as a user.
Customize the features and content presented to you.
Address your feedback, queries, and support needs.
Present relevant offers, both within the Application and across other platforms we manage.
Communicate significant updates, security advisories, or service-related notices.
We — together with the advertising and marketing collaborators who act on our behalf — may utilize information including your advertising identifier, inferred age bracket, country/region, gender, language preference, and your behavioral engagement within the Application to deliver advertising and promotional messaging that is relevant to you.
On these grounds, we assert a legitimate interest in processing data to:
Monitor activity and behavioral patterns associated with the Application.
Refine and more accurately direct our advertising and promotional campaigns.
Furnish pertinent information to our advertising and marketing associates for the same objectives.
By downloading, installing, or continuing to use Cleaner & Guard, you are deemed to have accepted that we and our advertising collaborators may gather and employ your information for tailored advertising and experience optimization, unless you take steps to opt out.
We suggest that you examine our partners' own privacy documentation to familiarize yourself with their individual data practices — we bear no responsibility for the privacy conduct of third parties, regardless of whether you encounter them through the Application or elsewhere.
Safeguarding your data is a priority. We implement commercially reasonable technical and organizational measures designed to protect against unauthorized access, loss, or misuse, and we mandate that any third-party processor handling data on our behalf adheres to comparable standards.
To uphold platform integrity, we rely on legitimate interest as the basis to process data in order to:
Observe and evaluate usage of the Application.
Identify and thwart fraudulent or unlawful conduct.
Take proportionate measures against users who breach our terms.
Nevertheless, no system can be rendered completely immune to threats, and we are unable to promise absolute security for your data or for any communications channel within the Application. We recommend exercising caution before sharing personal or sensitive details through the Application — any information disclosed to other users may be viewed or exploited by them, and anything posted in publicly accessible areas (such as community forums, if made available) should be regarded as publicly visible.
If you are situated in the European Economic Area, the United Kingdom, or Switzerland (collectively, the "Designated Regions"), your personal data is processed in accordance with the EU General Data Protection Regulation ("GDPR") or the corresponding local legislation, typically under the legal basis of our contractual relationship with you.
We may furnish your data to business collaborators — encompassing advertisers, ad-tech publishers, and analytics/measurement providers — who leverage it to present advertising, gauge user engagement, and analyze behavioral trends in order to enhance their own offerings. Following disclosure, the manner in which these entities handle your information is subject to their individual privacy policies, not this one.
Certain functionalities of Cleaner & Guard necessitate specific device-level permissions. You are free to decline any of these at any point through your device's settings, although doing so may restrict or disable particular features. The permissions we may seek include:
Storage

Administer files on external/shared storage

Our processing of personal data rests on the following legal foundations:
Contractual Performance — to furnish the services you have asked for and to authenticate your identity.
Statutory Obligation — to satisfy regulatory requirements such as financial record-keeping or mandatory disclosure to law enforcement authorities.
Legitimate Interests — to administer our user relationships, preserve the security of the Service, and correspond with you concerning the Application.
Consent — for operations such as deploying cookies or sharing your data with advertising partners.
In certain circumstances, the provision of specific personal data is a precondition for unlocking the complete functionality of the Application.
Subject to the laws that apply to you, the following rights may be exercised in relation to your personal information. To invoke any of them, please contact us at help@fengqiyuntu.com. We may request that you confirm your identity before acting on a request, and we reserve the right to decline a request where:
The law requires or permits us to refuse;
Compliance would impinge upon another individual's privacy;
It is necessary to safeguard our legal interests or property; or
The request is manifestly excessive or lacks merit.
F.1 Consent Withdrawal — Whenever we rely on your consent as the basis for processing, you retain the right to withdraw that consent at any time. Such withdrawal does not affect the lawfulness of processing undertaken prior to withdrawal.
F.2 Right of Access & Rectification — You may obtain a complimentary copy of the personal data we hold concerning you (subject to legally permitted exemptions) and may request that we amend or refresh any information that is inaccurate, except where the Application already enables you to make such corrections yourself.
F.3 Right to Erasure ("Right to Be Forgotten") — You may ask us to delete your data when it is no longer necessary for the original purpose for which it was gathered, when you have retracted the consent that underpinned its processing, or when you have raised a valid objection to its processing.
F.4 Right to Restrict Processing — You may request that we limit the processing of your data while we investigate an accuracy challenge, pending resolution of an objection, or as a substitute for erasure where processing is unlawful but you prefer restriction over deletion. We will inform you when any such restriction is removed.
F.5 Right to Object — You may oppose processing grounded in consent, contractual necessity, or legitimate interest, except where certain legal exceptions apply (for instance, the defense of legal claims).
F.6 Right to Data Portability — Where processing relies on consent or contractual necessity and is performed through automated means, you may request delivery of your data in a structured, commonly used, machine-readable format, or, where technically feasible, ask us to relay it directly to another controller.
F.7 Notification of Third Parties — If we have disclosed your data to external recipients, we will communicate any rectification, erasure, or restriction requests to those recipients, unless doing so proves impossible or would involve disproportionate effort.
F.8 Automated Decision-Making — You have the right not to be subjected to decisions based exclusively on automated processing (including profiling) that produce legal effects or similarly significant consequences, subject to statutory exceptions.
F.9 Lodging Complaints — Should you believe that your privacy rights have been infringed, please reach out to us at help@fengqiyuntu.com. You additionally retain the right to file a complaint with the data protection supervisory authority in your jurisdiction.
Our SDK and advertising collaborators each maintain their own privacy documentation, which dictates how they handle data collected via their tools. We exercise no control over these external entities' practices. Links are provided below for your reference:

This section augments the main body of this Policy and is directed exclusively at individuals who reside in California, in accordance with the California Consumer Privacy Act of 2018 ("CCPA") and related California statutes.
If you are not a California resident, the provisions below do not apply to you — please refer to the general Policy provisions instead.
H.1 Right to Know — You (or an agent you have authorized) may ask us to disclose: the categories of personal information we have gathered over the preceding 12 months; where that information originated; the business purpose behind its collection; and the classes of external parties with which it has been shared.
H.2 Right to Delete — You may ask us to remove personal information we store about you, and you may opt out of the sale or sharing of your data, except in cases where retention is necessary to:
Detect security breaches or protect against malicious, deceptive, or illegal activity;
Diagnose and remedy functionality errors;
Exercise free expression or another legally protected right, or to protect another user's ability to do so;
Perform internal operations that are reasonably aligned with the expectations of your relationship with us; or
Fulfill other legal duties prescribed under California law.
H.3 How to Submit a Request — Send verifiable requests to help@fengqiyuntu.com. Solely you or your authorized representative may submit a request; information-access requests are capped at two per 12-month period. Your request must supply adequate detail to allow us to authenticate your identity and comprehend the nature of your ask. We are unable to process requests that cannot be verified.
H.4 Response Timeframe — We endeavor to reply within 45 calendar days following receipt of a verified request. Should we require additional time (up to a total of 90 days), we will furnish an explanation and notify you of the extension via email, telephone, or other electronic means.
We do not impose a charge for handling requests unless they are duplicative, excessive, or manifestly without foundation — in such circumstances, we will communicate our rationale and supply a fee estimate before proceeding.
H.5 Non-Discrimination — We will never discriminate against you for exercising any of your CCPA rights — this means, among other things, that we will not withhold services, impose different pricing, or deliver a diminished quality of service as a consequence of your choice to exercise your rights.
H.6 Minors — The Application is not oriented toward children younger than 13, and we do not intentionally gather personal data from them. Should we discover that such data has been collected, we act to delete it promptly. Parents or guardians who suspect their child has supplied personal data to us are urged to contact us so that we may take appropriate measures. Users between the ages of 13 and 16 possess an affirmative right to opt in to data gathering; parents or guardians of individuals in this age band may also reach out to us on their behalf.
Cleaner & Guard is not designed for or directed at individuals under 13 years of age. We do not knowingly solicit or retain personal information from anyone in that age bracket. In the event that we learn a person under 13 has shared personal data with us, we will expeditiously remove it from our records. Parents or legal guardians who believe their child has transmitted personal information to us are encouraged to contact us so we can address the situation.
This Policy governs the information gathered while it remains in force. We may amend it from time to time; when we do, we will provide notification through means appropriate to the nature of the modification. Your continued engagement with the Application after any update becomes operative constitutes your acknowledgement of and agreement to the revised terms.
