    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 don't 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.
    
    NEW IN v2.0: GOOGLE DRIVE SCANNING + ENCRYPTED VAULT
    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. Your data, your keys, your control.
    
    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.
    
    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.
    
    TRY IT RISK-FREE FOR 7 DAYS
    Every new account receives a free 7-day trial of our premium Shield features, with absolutely no credit card required. During your trial, you get unlimited scans of Gmail and Google Drive, continuous monitoring, full Vault access, and full results without restriction.
    
    FLEXIBLE PRICING TO FIT YOUR NEEDS
    If you only need a quick check-up, our Free Plan allows you to run 2 scans per week and view up to 3 results per scan.
    
    To perform a complete cleanup, our Clean Sweep plan is a one-time payment of $14.99. This unlocks all results from a single scan, allowing you to bulk download files for safekeeping, permanently delete sensitive emails, and export a full CSV audit report.
    
    For ongoing protection, our Shield plan ($4.99/month or $49.99/year) offers unlimited scanning of Gmail and Google Drive, continuous real-time monitoring that alerts you to new sensitive documents, outbound email protection that warns you before you accidentally send sensitive information, and full Vault access to encrypt and store your most sensitive files.
    
    Have a family to protect? The Family plan ($9.99/month or $99.99/year) provides full Shield protection for up to 5 different Google accounts. Choosing an annual plan saves you two months free!

    Getting started is fast and secure. Simply install the extension and connect your Google account using Google's secure OAuth system. Click Scan, and ThunderSweep will locally process your Gmail and Google Drive. Within moments, your customized security report appears so you can start reviewing, deleting, or vaulting sensitive files.

    • 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
