Thank you for using PDF Compressor.
Your privacy is important to us. This Privacy Policy explains what information may be processed when you use our application, how your PDF files are handled, and how third-party services such as Google AdMob and our PDF compression service are used.
About the App
PDF Compressor allows users to compress PDF documents through an online PDF compression service.
Information We Collect
We do not collect personal information such as your name, email address, phone number, or contacts through the app.
However, certain information may be processed automatically by third-party services integrated into the application, including Google services.
Depending on how these services are used, information may include:
Device information
IP address
Advertising identifiers
Diagnostic and crash information
App performance information
Such information may be collected and processed by the applicable third-party service providers in accordance with their respective privacy policies.
PDF File Processing
When you choose an PDF file for compress:
When you select a PDF file for compression, the selected file is uploaded securely to our third-party PDF compression service using HTTPS.
The uploaded PDF is processed for the purpose of providing the requested compression service.
We do not use your PDF files for advertising, profiling, or any unrelated purpose.
Because the PDF compression service is provided through a third-party service/API, the selected file is transmitted to and processed by that service. The handling of the file is therefore also subject to the third-party service provider's policies and technical practices.
Uploaded and compressed files are intended to be automatically deleted from the processing server within 24 hours, and we do not intentionally maintain permanent backups of files processed through the service.
You retain ownership of your PDF documents. We do not claim ownership of the files you upload.
Important: We recommend that you do not upload highly sensitive, confidential, or legally restricted documents unless you are comfortable with them being transmitted to and processed by the third-party compression service.
PDF files are transmitted between your device and the applicable servers using HTTPS encryption to help protect data during transmission.
While we take reasonable measures to protect information transmitted through the app, no method of transmission or electronic storage can be guaranteed to be completely secure.
