Privacy Policy

This Privacy Policy ("Policy") is effective as of 30 June 2026 and applies to all users of the mobile application PDF Save (listed on Google Play as "Image to PDF – Fast Converter") developed and published by Pdfstudio ("we," "our," or "us").

By downloading, installing, or using the Application, you acknowledge that you have read, understood, and agree to be bound by the terms of this Policy. If you do not agree with this Policy, you must not use the Application.

PDF Save is an offline-first, privacy-centric productivity application available on the Google Play Store and Apple App Store. The Application enables users to convert images into PDF documents entirely on their device, without any server-side processing, cloud storage, or remote data transmission.

We are committed to protecting your privacy and ensuring that your personal data and files are handled with the highest standard of care. This Policy sets forth our practices with respect to data collection, usage, storage, and disclosure in connection with your use of the Application.

This Policy applies solely to the Application and does not extend to any third-party websites, applications, or services that may be accessible through links or integrations within the Application.

We wish to make unequivocally clear that PDF Save does not collect, store, process, or transmit any personal information from its users during the course of normal application operation. The Application functions without user accounts, registration, login credentials, or any form of user identification.

How We Process Your Files

When you use the Application to convert images to PDF:

• Your selected images are read locally from your device's gallery or camera.
• The PDF conversion engine runs entirely on your device's processor and memory.
• The resulting PDF file is saved locally to your device's file system.
• No image data, file contents, or PDF output is transmitted over the internet at any point.
• You may share the generated PDF manually through Android/iOS native sharing features, but this sharing is initiated and controlled entirely by you.

What We Do Not Do

For absolute clarity, PDF Save does not engage in any of the following activities:

• We do not upload your images to any server.
• We do not process your files on any remote or cloud infrastructure.
• We do not perform optical character recognition (OCR) on your documents.
• We do not apply any artificial intelligence or machine learning analysis to your images.
• We do not perform facial recognition or biometric processing.
• We do not maintain user accounts, profiles, or authentication systems.
• We do not collect payment information or process financial transactions.
• We do not synchronize data to any cloud backup service.
• We do not upload files in the background.
• We do not engage in any form of hidden or covert data collection.

PDF Save has been engineered from its foundation as an offline-first application. This architectural philosophy is central to our commitment to user privacy and is not merely a feature but a fundamental design principle.

Technical Implementation

• Local Image Processing: All image selection, cropping, reordering, and preview operations are performed using on-device libraries and APIs.
• On-Device PDF Generation: The PDF creation engine utilizes native device processing capabilities. The conversion from image format to PDF occurs entirely within the Application's local process space.
• Local File Storage: Generated PDF files are saved directly to the user's device storage. We do not provide, operate, or interface with any cloud storage solution.
• No Network Dependency: The Application's primary functionality does not require an active internet connection. Users can convert images to PDF while completely offline, including in airplane mode.
• No Server Infrastructure: PDF Save does not operate any application-specific backend servers, APIs, or cloud endpoints that receive or process user files.

PDF Save currently integrates Firebase Analytics as its sole analytics service. Firebase Analytics is a free app measurement solution provided by Google LLC ("Google") that provides insight into app usage and user engagement.

What Is Firebase Analytics?

Firebase Analytics is an event-based analytics service operated by Google that collects and aggregates anonymous usage data from mobile applications. It enables developers to understand how users interact with their applications, measure feature adoption, and identify potential issues.

What Anonymous Information May Be Collected

When Firebase Analytics is active, the following types of anonymized, aggregated information may be collected:

• App Interaction Events: Anonymous records of in-app actions, such as initiating a PDF conversion, opening the application, or navigating between screens. These events are reported without any association to user identity.
• Device Properties: Anonymized device characteristics, including device model, operating system version, screen resolution, and locale settings. Firebase Analytics uses these to segment data without identifying individual users.
• Anonymous Identifiers: Firebase may assign an anonymous, randomly generated identifier to each app installation instance. This identifier is not linked to any personal identity, account, or persistent device identifier.
• Crash and Error Reports: Firebase Crashlytics (if enabled) may collect anonymized crash data, including stack traces and device state at the time of a crash, to help us identify and fix bugs.

Google's Processing of Analytics Data

Firebase Analytics is operated by Google LLC. Google processes analytics data in accordance with its own privacy practices. We encourage you to review the following policies:

• Google Privacy Policy
• Firebase Analytics Data Policy
• Google Advertising Policies

Disabling Analytics

You may exercise control over analytics data collection through the following mechanisms:

• Android: Navigate to Settings → Google → Ads and opt out of interest-based advertising. You may also reset your advertising identifier at any time through device settings. Additionally, you can disable Firebase Analytics data collection for your device through Settings → Apps → PDF Save → Mobile Data & Wi-Fi and restricting background data.
• iOS: Navigate to Settings → Privacy & Security → Tracking and disable "Allow Apps to Request to Track." You may also reset your Identifier for Advertisers (IDFA) through Settings → Privacy & Security → Tracking.
• Device-Level Controls: Both Android and iOS offer device-level privacy settings that allow you to limit tracking and data collection. We encourage you to review and configure these settings according to your preferences.

PDF Save requests a limited number of device permissions necessary for its core functionality. Each permission is requested only when required and is used exclusively for the purposes described below. We do not use any permission for surveillance, tracking, or data collection beyond what is strictly necessary.

We implement reasonable technical and organizational safeguards to protect any data that may be associated with the Application. Given the offline-first nature of PDF Save, our security approach is fundamentally oriented toward on-device data protection.

On-Device Security Measures

• Local Processing: Because all image-to-PDF conversion occurs locally on your device, no user files are transmitted over the internet during normal operation. The absence of network transmission inherently eliminates the risks associated with data-in-transit interception, man-in-the-middle attacks, and server-side breaches.
• Operating System Protections: The Application operates within the security sandbox provided by the Android and iOS operating systems. Files created by the Application are subject to the operating system's native file-level permissions and encryption mechanisms (e.g., Android's full-disk encryption and iOS's Data Protection).
• No Remote Storage: Since user files are never stored on our servers or any cloud infrastructure, there is no risk of server-side data breaches affecting your personal files.
• Application Isolation: The Application's data is isolated from other applications on your device in accordance with the operating system's application sandboxing policies.

Limitations of Security Measures

While we employ reasonable safeguards, no system can guarantee absolute security. Factors beyond our control—including device-level security configurations, third-party application interactions, device theft or loss, and operating system vulnerabilities—may affect the security of data stored on your device. We recommend that you maintain up-to-date operating system versions and employ device-level security features such as screen locks and device encryption.

Analytics Security

For the limited analytics data processed by Firebase Analytics (as described in Section 4), Google employs its own security measures in accordance with its published security practices. This data is transmitted over encrypted channels (HTTPS/TLS) and is not linked to personal identifiers.

The Application integrates with the following third-party services:

We are not responsible for the data practices of these third-party services. Their collection and use of data are governed by their respective privacy policies, which we encourage you to review.

As a user of PDF Save, you are entitled to certain rights with respect to your data. Given that the Application does not collect personal information or user files, many of these rights are inherently satisfied by the Application's architecture. Nevertheless, we affirm the following rights in accordance with applicable privacy laws:

PDF Save is a general-purpose productivity application and is not directed at children under the age of 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect, store, or process personal information from children under 13.

COPPA Compliance (United States)

In compliance with the Children's Online Privacy Protection Act (COPPA), 15 U.S.C. §§ 6501–6506, and the implementing regulations at 16 C.F.R. Part 312:

• PDF Save does not knowingly collect personal information from children under 13.
• PDF Save does not require users to provide any personal information, including name, email address, age, or any other identifying information.
• PDF Save does not offer features designed to collect personal information from children.
• PDF Save does not contain social features, chat functionality, forums, or any mechanism through which a child could disclose personal information.
• PDF Save does not condition access to any feature on the disclosure of personal information.
• PDF Save does not use or disclose to third parties any personal information collected from children.

If we become aware that a child under 13 has provided personal information through the Application, we will take immediate steps to delete such information. If you are a parent or guardian and believe that your child has provided personal information to us, please contact us at ronik2599@gmail.com and we will take appropriate action.

Other Jurisdictions

Similar protections apply under the privacy laws of other jurisdictions, including but not limited to:

• European Union (GDPR): Processing of data from children under 16 (or the lower age provided by Member State law) requires parental consent. Since PDF Save does not collect personal data, this requirement does not apply.
• United Kingdom (UK GDPR): Comparable protections apply for children under 13.
• California (CCPA/CPRA): Additional protections exist for consumers under 16 under California law.

Given the offline-first architecture of PDF Save, international data transfers are generally not applicable to the Application's core functionality. User files (images and generated PDFs) remain on the user's device at all times and are not transmitted to any server or cloud service.

However, to the extent that Firebase Analytics processes limited, anonymized analytics data, such data may be transferred across international borders as part of Google's global infrastructure. Google's international data transfer practices, including reliance on Standard Contractual Clauses (SCCs), Binding Corporate Rules (BCRs), and other legal mechanisms, are described in Google's data processing terms and privacy documentation.

For the purposes of applicable data protection laws, including but not limited to the GDPR, UK GDPR, and LGPD:

• International transfers of analytics data are subject to Google's standard data transfer safeguards.
• We have not and do not intend to enter into separate data processing agreements for analytics data that is processed entirely by Google.
• Users seeking more information about Google's international data transfer practices should consult Google's Compliance Resources.

This section describes the specific privacy regulations and legal frameworks with which PDF Save is designed to comply. Given that the Application does not collect personal data and operates on an offline-first basis, many regulatory obligations are inherently satisfied by the Application's architecture.
