Privacy Policy for Fast Cleaner

Last Updated: April 3, 2026

Welcome to Fast Cleaner ("we", "us", or "our"), a mobile application designed to help you clean up your device storage, optimize performance, and manage files efficiently. This Privacy Policy explains how we collect, use, store, and protect your information when you use our Fast Cleaner app (the "App") on your Android device. By using the App, you agree to the collection and use of information in accordance with this policy. This policy is compliant with Google Play Store Developer Policies and applicable privacy laws, including the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA).

1. Information We Collect

We collect only the information necessary to provide and improve the App’s core functionality, ensure security, and enhance your user experience. We do not collect unnecessary personal data, and all data processing adheres to Google Play’s user data guidelines[10]. The information we collect falls into the following categories:

1.1 Device Information

To ensure the App runs smoothly and is compatible with your device, we may collect non-personally identifiable device information, including:

• Device model, brand, and operating system (OS) version

• Unique device identifiers (e.g., Android ID, IMEI, or advertising ID) – used solely for app performance tracking and crash debugging

• Device storage capacity, available space, and storage usage details

• Network connection type (Wi-Fi, mobile data) and signal strength (only when necessary for app updates)

This information is collected automatically when you install and use the App, and it is not linked to your personal identity.

1.2 App Usage Data

We collect data about how you use the App to improve its functionality and address user needs. This includes:

• Features you use (e.g., junk file cleaning, duplicate photo detection, app cache cleaning)

• Cleaning history (e.g., number of files cleaned, storage space freed, types of files removed)

• App interaction data (e.g., time spent using the App, buttons tapped, error messages encountered)

• App performance data (e.g., load time, crash logs, freezing incidents) – used to fix bugs and optimize performance

1.3 Data Related to Core Cleaning Functionality

To provide the App’s core cleaning services, we access and process certain files on your device (all processing is done locally on your device unless stated otherwise):

• Junk files (e.g., app cache, residual files, temporary files) – to identify and remove them with your explicit consent

• Duplicate photos, similar images, and screenshots – to help you identify and delete redundant files (we do not store or upload these photos/videos to our servers)[5]

• Large files and unused apps – to recommend items for cleaning and free up storage space

Note: We do not access, collect, or store your personal files (e.g., personal photos, videos, messages, contacts) without your explicit permission. All cleaning actions require your confirmation before any files are deleted.

1.4 Optional Information

If you choose to use certain optional features, we may collect additional information:

• User feedback: If you submit feedback (via the App’s feedback feature), we may collect your message, contact information (if you provide it), and related app logs to address your concerns.

• In-app purchases: If you make in-app purchases, Google Play’s payment system handles all payment information (e.g., credit card details), and we only receive confirmation of the purchase (e.g., order ID, purchase date) to unlock premium features.

2. How We Use Your Information

We use the collected information for the following purposes, all of which are aligned with the App’s core functionality and Google Play policies:

• To provide and maintain the App’s core cleaning services (e.g., identifying junk files, detecting duplicates, optimizing device performance).

• To improve the App: We analyze usage data and performance metrics to fix bugs, enhance features, and tailor the App to user needs.

• To ensure security: We use device and usage data to detect and prevent malicious activity, protect the App from malware, and ensure safe operation in compliance with Google’s malware protection guidelines.

• To respond to user feedback: We use feedback information to address your questions, resolve issues, and improve the user experience.

• To provide customer support: If you contact us for support, we use the information you provide to assist you.

• To process in-app purchases: We use purchase confirmation data to unlock premium features and maintain accurate purchase records.

We will never use your information for purposes unrelated to the App’s functionality without your explicit consent, and we will not sell, rent, or share your information with third parties for marketing purposes.

3. Data Storage and Security

3.1 Storage

Most of the data we collect (e.g., cleaning history, device information, usage data) is stored locally on your device. Any data that is stored on our servers (e.g., user feedback, purchase records) is stored securely on encrypted servers with restricted access. We retain your data only for as long as necessary to provide the App’s services or comply with legal obligations. Once the data is no longer needed, we delete it securely.

3.2 Security

We take reasonable measures to protect your information from unauthorized access, disclosure, alteration, or destruction. These measures include:

• Encryption of data stored on our servers and data transmitted between your device and our servers (if applicable).

• Restricted access to user data by authorized personnel only.

• Regular security updates and audits to identify and address potential vulnerabilities.

• Compliance with Google Play’s security requirements and best practices for data protection.

While we strive to protect your information, no method of transmission or storage is 100% secure. We cannot guarantee absolute security, but we will always take reasonable steps to minimize risks.

4. Third-Party Services

We may use third-party services to help us provide and improve the App. These third parties are bound by strict privacy obligations and are only allowed to use your information to perform the services we request. The third-party services we may use include:

• Google Play Services: For in-app purchases, app updates, and crash reporting.

• Analytics tools: To analyze app usage and performance (we do not share personal data with these tools).

We do not share your personal information with any third parties for their own marketing or commercial purposes. Any third-party service provider that processes your data must comply with Google Play policies and applicable privacy laws.

5. Your Rights

Under applicable privacy laws (e.g., GDPR, CCPA), you have the following rights regarding your information:

• Right to access: You can request a copy of the information we hold about you.

• Right to correction: You can request to correct any inaccurate or incomplete information.

• Right to deletion: You can request to delete your information (note: deleting certain data may affect the App’s functionality).

• Right to withdraw consent: If you have given consent for certain data collection, you can withdraw it at any time (this may limit your ability to use certain features).

6. Children’s Privacy

The App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected information from a child under 13 without parental consent, we will delete that information immediately. If you are a parent or guardian and believe your child has provided us with personal information, please contact us to request deletion.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, Google Play policies, or applicable laws. When we make changes, we will update the "Last Updated" date at the top of this policy. We will also notify you of significant changes by displaying a notice within the App or sending you a push notification. Your continued use of the App after the changes take effect constitutes your acceptance of the updated policy.
