What's Included

Each download includes:

• Complete database in SQLite format (.db) with full notification letter text
• Excel workbook (.xlsx) and CSV export for simplified access
  
• Comprehensive documentation

Try Before You Buy

A sample download of the database is available here, including documentation and sample data across all provided formats:

• Download SQLite sample (.db file, recommended)
• Download Excel sample (.xlsx file)
• Download CSV sample (.csv file)

Important: To prevent issues when importing into Excel, the pdf_contents_cleaned field is omitted from both the Excel and CSV exports. Despite our best efforts—such as truncating long text fields or splitting data across multiple sheets—this field was frequently causing problems. Excel has strict limits on the number of characters allowed per cell (32,767 characters) and a maximum number of URLs per sheet; including the full text often led to workbook corruption or import errors.

We strongly recommend working with the SQLite (.db) export if you need access to the full text of breach notifications. The Excel and CSV formats have been optimized for quick access and ease of use, but they omit some fields to ensure data integrity and compatibility with Excel.

Pricing

We offer a significant discount for academics. However, if you are unable to purchase and working on a project that may advance consumer privacy or security in alignment with our mission, you may apply for a single download pass fee waiver.
