PDFPX — Privacy Policy, Help & Support

Last Updated: April 2, 2026

Privacy Policy

PDFPX ("the App") is developed and published by 1KB Apps. Your privacy matters to us. This Privacy Policy explains what information the App collects, how it is used, and your rights as a user.

1. Data Collection

PDFPX is designed with privacy at its core. The App does not collect, store, or transmit any personal data, files, or images to external servers.

• PDF Files: All PDF files you select are processed entirely on your device. Your files are never uploaded to any server.
• Converted Images: JPG and PNG images generated from your PDFs remain on your device. They are stored temporarily during the conversion session and saved to your Photo Library only when you choose to do so.
• No Accounts: The App does not require you to create an account, sign in, or provide any personal information such as your name, email address, or phone number.

2. Data Usage

Since PDFPX does not collect personal data, there is no personal data to use, sell, or share. All conversion processing happens locally on your device using Apple's native PDFKit and Core Graphics frameworks.

3. Data Storage

• Temporary Files: During a conversion session, temporary image files are created in the App's sandbox directory. These files are automatically cleaned up by the operating system.
• Conversion History: A minimal, on-device record of your recent conversions (file name, size, date) is stored locally for your convenience. This data never leaves your device.
• Preferences: Your settings — such as theme preference (Dark, Light, or System) and default export format (JPG Fast, JPG High Quality, or PNG Lossless) — are saved locally on your device using standard iOS storage.

4. Third-Party Services

PDFPX uses the following third-party service:

• RevenueCat: The App uses RevenueCat to manage in-app subscriptions and purchases. RevenueCat processes transaction data through Apple's App Store infrastructure to verify your subscription status. RevenueCat does not receive your PDF files, converted images, or any personal content. For more information, see RevenueCat's Privacy Policy.

5. Analytics

PDFPX does not include any third-party analytics SDKs, tracking pixels, or usage telemetry. The App does not track how you use it, which files you convert, or any other behavioral data.

6. User Rights

Since the App does not collect or store personal data on any server, there is no personal data to request, modify, or delete. All your data remains on your device and is fully under your control. You can delete the App at any time to remove all locally stored data, including conversion history and preferences.

7. Children's Privacy

PDFPX does not knowingly collect any personal information from children under the age of 13 (or the applicable age in your jurisdiction). The App does not require an account or any personal information to use. If you believe a child has somehow provided personal information through the App, please contact us at the email below and we will take appropriate steps.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Last Updated" date. We encourage you to review this page periodically. Continued use of the App after any changes constitutes your acceptance of the updated policy.

Frequently Asked Questions

Q: What does PDFPX do?

A: PDFPX converts PDF pages into high-quality JPG or PNG images directly on your iPhone or iPad. You select a PDF, choose which pages to convert, pick an output format, and the App generates image files you can save or share.

Q: Is PDFPX free to use?

A: Yes. You can import any PDF and preview your converted images for free. Saving to your Photo Library, sharing, and exporting converted images require a PDFPX Pro subscription.

Q: What output formats are available?

A: PDFPX offers three conversion presets:

• JPG Fast — Fastest conversion with smaller file sizes, ideal for sharing.
• JPG High Quality — High-quality JPG export with balanced file size.
• PNG Lossless — Maximum quality, lossless export with larger file sizes.

Q: Can I select specific pages to convert?

A: Yes. After importing a PDF, the App shows thumbnail previews of all pages. You can select or deselect individual pages, or use "Select All" / "Deselect All" to quickly choose which pages to convert.

Q: Are my PDF files uploaded to any server?

A: No. All processing happens entirely on your device. Your PDF files and converted images never leave your device. PDFPX works 100% offline.

Q: Can I change the App's appearance?

A: Yes. Go to Settings inside the App and choose from Dark, Light, or System theme.

Q: What should I do if a conversion fails?

A: Ensure the PDF file is not corrupted and is fully downloaded on your device. If the issue persists, try restarting the App. If you continue to experience problems, contact us at support@1kbapps.com with details about the PDF and your device.

Q: Where are my converted images saved?

A: When you tap "Save All to Photos," the converted JPG or PNG images are saved directly to your device's Photo Library. You can also use the "Share Images" option to send them via AirDrop, Messages, Email, or any other sharing method supported by your device.
