Tax returns, SSNs, bank statements, medical records — sitting in your inbox for years. ThunderSweep finds them in 60 seconds so you can delete them safely.
Three simple steps to clean up years of sensitive documents hiding in your inbox.
One-click Google sign-in. We only request read access — ThunderSweep never modifies anything without your permission.
ThunderSweep scans your attachments locally in your browser. PDFs, spreadsheets, Word docs, even ZIP files.
See exactly what was found. Download a report, then safely bulk-delete sensitive emails to Gmail's trash.
Powerful scanning, simple interface, total privacy.
Scans PDFs, Word docs, Excel spreadsheets, and ZIP archives for sensitive patterns.
Finds SSNs, tax forms, bank account numbers, medical records, EINs, and more with validated checks (Luhn, structure validation).
Download a CSV report first, then bulk-delete with a 4-step safety confirmation. Moves to trash — never permanent.
Large inbox? Pause your scan anytime and pick up right where you left off. Progress is saved automatically.
Filter by category (tax, financial, medical), date range, or keyword. Sort by sensitivity, date, or sender.
