Last Updated: July 20, 2026

1. Introduction

Welcome to PaperKnife Plus, an all-in-one PDF and media utility application designed to simplify your digital tasks. We are deeply committed to protecting your privacy and ensuring that your personal information is handled safely, responsibly, and transparently.

This Privacy Policy explains how we collect, use, and protect information when you use our application. We have written this document in simple, easy-to-understand language to ensure that everyone can know exactly how their data is treated.

2. Information We Collect

2.1 Information You Provide

We only collect personal information that you voluntarily choose to provide to us. For example, if you contact us for feedback, request customer support, or send bug reports via email, we will collect your email address and any other information you include in your message. We use this information solely to address your inquiries, fix issues, and improve our application.

2.2 Automatically Collected Information

When you use PaperKnife Plus, certain information may be collected automatically by the basic third-party services we integrate, such as analytics and advertising providers. This information generally does not reveal your specific identity. It may include:

Device information, such as your hardware model and operating system version.
Basic analytics data, such as app usage trends, feature interaction, and crash reports.
Device identifiers strictly for standard advertising or analytics purposes.

2.3 Information We Do NOT Collect

Crucial Notice: We want to be completely transparent about what we do not do. All of your core processing tasks—including PDF editing, merging, signing, and PDF or Image Exports—happen ENTIRELY LOCALLY on your device.

We do not upload, store, monitor, or process your files, documents, media, or private content on any remote servers. Your personal files remain safely and solely on your own device at all times.

3. How We Use Your Information

The very limited information we do collect is used in the following specific ways:

To provide, maintain, and improve the local functionality of the PaperKnife Plus application.
To respond effectively to your user support requests, questions, and feedback.
To analyze general usage trends to optimize the user experience and interface.
To serve relevant advertisements in the future, which helps support the continuous development of the app.

4. Data Storage and Security

Your privacy is highly important to us. We rely on standard, built-in local storage mechanisms (such as SharedPreferences) to save your app settings and personal preferences directly on your device.

We implement basic data safety measures to protect the limited information that might be collected. However, please remember that no method of electronic storage or transmission over the internet is 100% secure, and we cannot guarantee absolute security against all threats.

5. Third-Party Services

PaperKnife Plus integrates with select third-party services to provide a better user experience, analyze app health, and support development. These services may collect basic device identifiers and usage data as described in their respective privacy policies. Our current third-party partners include:

Google AdMob: For serving standard advertisements within the app.
Firebase Analytics: For understanding app usage and improving overall performance.
OneSignal: For delivering important push notifications and app updates.

We encourage you to review the privacy policies of these trusted third-party services to fully understand their data handling practices.

6. Permissions

To function correctly and provide its features, PaperKnife Plus requires certain standard permissions on your device. We ask for these permissions strictly for the following reasons:

Storage Access: Required to read the files you want to edit or compress, and to securely save your processed PDFs and media files back to your device storage.
Internet Access: Necessary for receiving crash reports, basic analytics, and loading third-party advertisements or push notifications.
Notification State: Required to send you timely updates about background processing tasks or important app announcements.

7. Children's Privacy

PaperKnife Plus is designed for a general audience and is suitable for everyone. We fully comply with the Children's Online Privacy Protection Act (COPPA). We do not knowingly collect personal information from children under the age of 13.

If you are a parent or guardian and become aware that a child has provided us with personal information, please contact us immediately. We will take swift steps to locate and delete such information.

8. Advertising and Cookies

To keep the app free or affordable for our users, we may display advertisements provided by Google AdMob. These ad networks may use anonymous device identifiers or similar standard tracking technologies to provide personalized ads based on your general interests.

You have the right and ability to opt-out of personalized advertising at any time by adjusting the global ad settings on your Android device (this is usually found in Settings > Google > Ads).

9. Data Retention

Any local data or settings generated by PaperKnife Plus stay securely on your device until you choose to clear the app data or uninstall the application entirely.

Information handled by our integrated third-party services (like anonymous analytics or ad identifiers) is retained according to their own standard data retention cycles and policies.

10. Your Rights and Choices

We believe you should have full control over your local data. As a user of PaperKnife Plus, you can choose to:

Delete all your processed files and reset your app settings by clearing the app data in your device's settings menu.
Disable notifications for PaperKnife Plus entirely through your device's global notification settings.
Opt-out of personalized ad tracking globally through your Android privacy settings.

11. International Data Transfers

While all your personal files and documents stay entirely local on your device, the basic diagnostic and analytics data collected by our third-party services (such as Google and Firebase) may be transferred to and processed on international server nodes located outside your country of residence.

By using the application, you consent to these standard international data transfers managed by our trusted service partners.

12. Changes to This Privacy Policy

We may periodically update this Privacy Policy to reflect changes in our practices, new technologies, or evolving legal requirements.

Any modifications will be posted directly within the app's policy view, and the "Last Updated" date at the top of this document will be revised accordingly. We encourage you to review this policy periodically to stay informed.

13. Legal Basis for Processing (GDPR)

For users residing in the European Economic Area (EEA), our legal basis for processing any limited personal data generally falls under two clean categories:

Consent: Where you have given explicit consent, such as opting into receiving personalized advertising.
Legitimate Interest: Where processing is necessary for our legitimate business interests, such as providing app functionality, improving our services, and ensuring security, provided those interests are not overridden by your fundamental data protection rights.

14. California Privacy Rights (CCPA)

Under the California Consumer Privacy Act (CCPA), residents of California are granted specific privacy rights. We want to explicitly confirm that PaperKnife Plus does not sell your personal data.

The minimal information collected is used solely for core app functionality, basic analytics, and standard advertising purposes exactly as outlined in this policy.

15. Do Not Track Signals

We do not currently respond to specific "Do Not Track" signals originating from web browsers. However, PaperKnife Plus deeply respects and strictly follows the default device-level ad personalization and privacy tracking settings configured on your Android device.

16. Links to Other Websites

PaperKnife Plus may contain external links or advertisements that lead to other websites or services that are not operated or controlled by us.

We are not responsible for the privacy practices, content, or security of these third-party sites. We strongly advise you to carefully read the privacy policy of every site you visit via click-throughs from our app.
