Privacy Policy - PDF Reader: All File Tools

1. Introduction

Thank you for using PDF Reader: All File Tools ("the App").

We highly value your privacy and are committed to protecting your personal information and data security.

This Privacy Policy explains how we collect, use, store, and protect user data in compliance with applicable laws and platform policies.

By using this App, you agree to this Policy. If you disagree, please stop using it.

2. Information We Collect and Use

We do not actively collect or upload any personally identifiable information.

To provide essential document functions, the App may access certain data only after user authorization and process it entirely on the device:

Files and documents — used for scanning, displaying, and managing local PDFs, Word, Excel, and other document files;
Images and media files — accessed only when the user chooses to convert images to PDF;
Performance data — such as crash logs and diagnostic reports, used to improve stability and fix bugs.

All data processing is limited to the declared purpose, handled locally, and never accessed in the background or without consent.

3. Permissions We Use

To ensure core functionality, this App may request:

MANAGE_EXTERNAL_STORAGE — to scan, import, and organize document files on the device;
FOREGROUND_SERVICE_SPECIAL_USE — to keep file processing tasks stable when handling large or complex PDFs;
CAMERA — for scanning paper documents into PDF (only when triggered).

All permissions are granted only after explicit user consent and can be revoked at any time through device settings.

4. Purpose of Use

The information accessed or generated within the App is used strictly to:

Deliver key document services such as viewing, editing, converting, and managing PDF and other file types;
Optimize performance and ensure smooth operation through local processing and diagnostic analysis;
Maintain application stability and prevent unauthorized or abnormal operations.

We never sell, upload, or misuse any user data.

5. Data Storage and Security

All file operations, including viewing, editing, and conversion, are performed locally on your device.

No personal files, PDFs, images, or messages are ever uploaded or stored on our servers.

We adopt HTTPS encryption, permission control, and local data isolation to ensure the security and privacy of your content.

We strictly follow the principle of minimal data collection — only the data necessary for functionality is accessed, and always under user control.

6. Third-Party Services

We may integrate SDKs from third-party partners for analytics or advertising purposes, including Google AdMob, Firebase, AppLovin (MAX), Facebook, and others.

These SDKs only receive anonymized statistical data (e.g., ad performance or crash metrics) and cannot access user documents, personal files, or messages.

All cooperation complies with applicable laws and strictly prioritizes user privacy.

7. User Rights

You have full control over your permissions and data access.

You may review, modify, or withdraw previously granted permissions at any time directly through your device's system settings, including access to storage, camera, or other sensitive features.

We respect and protect your right to manage personal information — your consent and privacy choices are always under your control.

8. Age Restriction

This App is designed for users aged 13 and above.

We do not knowingly collect data from minors.

If such data is detected, it will be promptly deleted to ensure compliance and protect privacy.

9. Policy Updates

We may update this Privacy Policy as laws, regulations, or product features evolve.

All major changes will be announced on our official website.

Continued use of the App indicates your acceptance of the updated policy.
