Privacy Policy
Last updated: April 3, 2026
Overview
PDFCheck ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our PDF metadata analysis service.
Information We Collect
Files You Upload
When you upload a PDF file for analysis, the file is processed in memory on our servers. We do not store, save, or retain your PDF files. The file is analyzed immediately and then discarded from memory.
Metadata Storage
We store only the extracted metadata (not the file itself) in a local database associated with your session. This includes:
- Original filename
- File hash (SHA-256, for duplicate detection)
- File size
- Extracted PDF metadata (dates, author, creator application, etc.)
- Verification results
Session Information
We use anonymous session identifiers to provide you with analysis history during your visit. We do not collect or store personal information such as:
- Names or email addresses
- Account credentials
- Payment information
- Personal identification
How We Use Your Information
The metadata we collect is used solely to:
- Provide you with PDF analysis results
- Display your analysis history during your session
- Allow you to review and delete your analysis records
Data Security
We implement security measures to protect your data:
- HTTPS encryption for all data transmission
- No file storage - files are processed in memory only
- Session-based access to analysis history
- IP addresses are hashed and not stored in plain text
Your Rights
You have the right to:
- Delete any analysis records associated with your session
- Clear your browser session to remove all association with stored metadata
- Use the service without providing any personal information
Cookies
We use only essential cookies required for session management. We do not use tracking cookies, advertising cookies, or analytics services that track individual users.
Third-Party Services
We do not share your data with third parties. PDF analysis is performed entirely on our servers using open-source libraries, with no external API calls that could expose your document content.
Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
