Take control of your data! Find, download, and delete sensitive attachments. 100% local processing! Emails stay on your computer.

ThunderSweep - Gmail Security Scanner THE HIDDEN RISK IN YOUR INBOX Think about how long you have had your Gmail account. Over the years, you have likely received or sent tax returns, bank statements, medical records, and legal contracts. Most of us read these emails once and forget about them. But they don't disappear. They sit in your inbox forever, creating a massive security risk. If a hacker gains access to your email—or if an old connected app gets breached—they instantly have access to your entire financial and personal digital life. TAKE BACK CONTROL OF YOUR DATA ThunderSweep is designed to find those forgotten, sensitive documents hiding in your attachments so you can proactively delete them. It acts as a dedicated security scanner for your email, bringing years of buried files to the surface. 100% PRIVATE AND LOCAL PROCESSING Your privacy is our absolute priority. Unlike other apps that upload your data to their servers, ThunderSweep runs entirely inside your browser. Your emails never leave your computer, and we use zero cloud processing. We do not collect, store, or sell any of your data. The scanning happens locally, ensuring your information remains strictly yours. HOW THUNDERSWEEP FINDS WHAT OTHERS MISS Gmail's built-in search only looks at the plain text of emails and the names of files. ThunderSweep goes much deeper. Our advanced local engine extracts and parses the actual text inside your attachments—including PDFs, Word documents (.docx), spreadsheets, and even compressed ZIP files—regardless of what the file is named. Our scanner is trained to identify the exact data patterns that identity thieves look for: • Tax documents (W-2s, 1099s, returns) • Financial records (bank statements, account numbers) • Social Security numbers • Medical records and health information • Legal documents (contracts, agreements) • Employment documents (offer letters, pay stubs) • Business documents (EINs, formation papers) Once the scan finishes, ThunderSweep generates a detailed, categorized report right in your browser dashboard, showing you exactly where your exposures are.
