Privacy Policy

This Privacy Policy describes how the PDF Compressor mobile application (“the App”, “we”, “us”) handles information when you use it. By using the App, you agree to the practices described here.

1. Who we are

PDF Compressor is developed by Sooryanarayanan (“the Developer”). For any questions about this policy, contact us at apps.narayananb@gmail.com.

2. What the App does

The App lets you:

• Compress PDF and image documents.
• Convert images into PDF files.

All document processing happens locally on your device. Your files are never uploaded to our servers, and we do not have access to their contents.

3. Information we collect

3.1 Files you select

When you pick a document or image, Android grants the App temporary access to that file through the system file picker (Storage Access Framework). The App reads the file in memory, produces the compressed or converted output, and writes the output back to the location you choose. We do not retain copies, do not transmit your files, and do not request broad storage permissions.

3.2 Analytics data (Firebase Analytics)

The App uses Google Firebase Analytics to understand how the App is used in aggregate. Firebase may automatically collect:

• A randomly generated app-instance identifier
• Device model, operating system version, and language
• Approximate region (derived from IP address, not stored as a precise location)
• App events such as screen views and feature usage (e.g., “compression completed”)
• Crash and performance diagnostics

This data is processed by Google. We do not link it to your name, email, or any personal identifier. For details on how Google processes this data, see Google’s Privacy & Terms and the Firebase Privacy Information pages.

3.3 Network permissions

The App requests INTERNET and ACCESS_NETWORK_STATE permissions. These are used only by Firebase Analytics to send anonymous usage data. The App does not transmit your documents or images over the network.

4. Information we do NOT collect

• We do not collect your name, email address, phone number, or account information.
• We do not access your contacts, calendar, microphone, camera, or precise location.
• We do not collect or transmit the contents, file names, or metadata of the documents you process.
• We do not sell or share your data with advertisers.

5. Permissions used by the App

6. Children’s privacy

The App is not directed to children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children.

7. Data retention

Because the App does not upload your documents, there is nothing to retain on our side. Firebase Analytics data retention is configured to Google’s defaults; you can opt out of analytics collection by uninstalling the App.

8. Your rights

Depending on where you live (e.g., EEA, UK, California), you may have rights to access, correct, or delete personal data we hold about you. Because we do not collect personally identifying information through the App, we are usually unable to associate analytics data with an individual. You can:

• Reset the Firebase app-instance identifier by clearing the App’s storage in Android settings.
• Uninstall the App to stop all further data collection.

9. Security

We rely on Android’s app sandboxing and on Firebase’s transport-layer encryption to protect data in transit. No method of electronic storage or transmission is 100% secure.

10. Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the “Last updated” date above. Continued use of the App after changes means you accept the revised policy.
