Privacy Policy

Welcome to PDF Converter ("we," "our," or "us"), accessible at pdfconverter.bd. We are committed to protecting your privacy and being completely transparent about how your data is handled when you use our services. This Privacy Policy explains what information we collect, how we use it, and what rights you have regarding your data.

PDF Converter was founded on a fundamental belief: online PDF tools should not require you to sacrifice your privacy. Unlike many competitors in the market, we designed our entire system architecture around the principle of minimal data collection and zero file retention. When you use PDF Converter, your documents are processed in real-time and purged immediately — there are no temporary storage queues, no backup copies, and no file archives.

By using our website and services, you agree to the collection and use of information in accordance with this policy. If you do not agree with any part of this policy, please do not use our services.

This is the most important section of our privacy policy. When you upload a PDF or any other document to PDF Converter for processing (merging, splitting, compressing, converting, etc.), here is exactly what happens:

1. Upload: Your file is transmitted securely to our processing server via HTTPS encryption.
2. Processing: Your file is processed in memory or in a temporary directory on our server using open-source tools (QPDF, LibreOffice, Poppler).
3. Delivery: The processed result is sent back to your browser for download.
4. Deletion: The original file and all temporary processing files are permanently deleted from our server. This happens automatically and immediately — typically within seconds of the result being delivered.

We do not create backup copies of uploaded files. We do not store files in a queue for later processing. We do not archive processed documents for any reason. We do not run any analysis, machine learning, AI training, or data mining on the contents of your documents. The only purpose your file serves on our server is to be processed according to your request and then destroyed.

In the event of a server error or interrupted connection during processing, any partial files in our temporary directory are cleaned up by an automated process that runs continuously. No orphaned files persist beyond the cleanup cycle.

We collect minimal information necessary to operate and improve our service:

Automatically Collected Information:

• Browser type and version (for compatibility purposes)
• Device type (desktop, mobile, tablet — for responsive design)
• Referral source (how you found our website)
• Pages visited and tools used (to understand which tools are most popular)
• Anonymized usage statistics (number of conversions, not file contents)

Information We Do NOT Collect:

• File contents, names, or metadata from uploaded documents
• Personal identification from uploaded document contents
• IP addresses for tracking purposes (we may log IPs temporarily for security and rate limiting only)
• Keystroke patterns, mouse movements, or screen recordings

Account Information (Optional): If you create an account to use our Developer API, we collect the email address and password you provide during registration. This information is stored securely and is used solely for authentication and account management purposes. Passwords are hashed using industry-standard algorithms and cannot be viewed by anyone, including our team.

We use minimal cookies necessary for website functionality. We do not use advertising cookies, retargeting pixels, or cross-site tracking technologies. We do not sell or share cookie data with third parties. We may use a simple analytics solution to understand aggregate traffic patterns, but this data is anonymized and cannot be used to identify individual users.

If you create an account, we use a session cookie to keep you logged in. This cookie is essential for the service to function and expires when you log out or after a reasonable inactivity period.

Your files are never sent to third-party services for processing. All document processing happens on our own infrastructure using open-source tools that we install and control. We do not use cloud-based AI services, external APIs, or third-party processing pipelines to handle your documents.

We may use third-party services for non-document-related functions such as hosting infrastructure, DNS management, and anonymized analytics. These services do not have access to your uploaded documents.

You have the right to:

• Data Access: Request information about any personal data we hold about you.
• Data Deletion: Request the deletion of any account-related data we hold.
• Data Portability: Receive a copy of your account data in a structured format.
• Opt-Out: Opt out of non-essential cookies and analytics tracking.

Since we do not store uploaded documents beyond the processing window, there is no document data for us to delete, access, or export on your behalf. Your files simply don't exist on our systems after processing is complete.

To exercise any of these rights, contact us at [email protected].

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make material changes, we will update the "Last updated" date at the top of this page. We encourage you to review this page periodically for the latest information on our privacy practices.
