ThunderSweep — Gmail & Google Drive Security Scanner

THE HIDDEN RISK IN YOUR INBOX AND DRIVE
Think about how long you have had your Google account. Over the years, you have likely received or sent tax returns, bank statements, medical records, and legal contracts — and saved files directly to your Google Drive. Most of us read these once and forget about them. But they do not disappear. They sit in your Gmail and Google Drive forever, creating a massive security risk. If a hacker gains access to your account — 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 Gmail attachments and Google Drive files so you can proactively delete them or lock them away in an encrypted private Vault. It acts as a dedicated security scanner for your entire Google account, bringing years of buried files to the surface — then helping you organize, protect, and share them securely.

NEW IN v2.0: GOOGLE DRIVE + ENCRYPTED VAULT + SECURE SHARING
ThunderSweep now scans both Gmail and Google Drive in a single pass. Found something you want to keep safe instead of deleting? Move it to your ThunderSweep Vault — encrypted directly inside your own Google Drive using AES-256-GCM encryption. Your vault password never leaves your device. Not even we can open your files.

The Vault is now a full secure document manager:
• Vault emails with one click from Gmail's inbox using the ⚡ Vault button — no need to open each email
• Search your vault by name, category, tag, or year
• Rename files, set expiry reminders, and organize by category
• Bulk-select files to delete, restore, or export in one action
• Create encrypted Secure Notes for account numbers, PINs, policy details, and anything else worth protecting
• Package vault files into a password-protected ZIP (TSxport) to share securely with anyone — no ThunderSweep required
• Transfer files directly to another ThunderSweep user's vault via TS Share — end-to-end encrypted, no plaintext ever touches our servers
• Smart seasonal reminders alert you when key documents are missing (W-2, 1099, passport) and notify you 30 and 7 days before stored documents expire

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 and Drive files never leave your computer — we use zero cloud processing. We do not collect, store, or sell any of your data. All scanning happens locally, ensuring your information remains strictly yours. ThunderSweep complies with Google's API Services User Data Policy including the Limited Use requirements.

HOW THUNDERSWEEP FINDS WHAT OTHERS MISS
Gmail's built-in search only looks at plain text of emails and file names. ThunderSweep goes much deeper. Our advanced local engine extracts and parses the actual text inside your attachments and Drive files — including PDFs, Word documents (.docx), spreadsheets, and even compressed ZIP files — regardless of what the file is named. You can also filter results instantly by sender category: Tax/IRS, Payroll, Banking, Medical, or Mortgage.

Our scanner identifies 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 — across both Gmail and Google Drive.
