PrivyShi — Email Privacy Shield

About

PrivyShi hides sensitive email content in real time — scrambling sender names, subject lines, and inbox previews into unreadable text. Hover over any protected element to instantly reveal the original. Perfect for working in public, on screen shares, or in open offices.

🔒 WHAT IT PROTECTS
• Sender names and email addresses
• Subject lines and inbox preview snippets
• CC / BCC recipients and attachment names
• Email body text (optional, off by default)

✨ HOW IT WORKS
When you open Gmail, Outlook, Proton Mail, or Yahoo Mail, PrivyShi automatically scrambles all visible email data into randomised characters. Simply hover your cursor over any text to reveal it instantly — no clicks, no toggles. Move away and it re-hides.

⚙️ THREE SCRAMBLE MODES
• Normal — character-for-character random substitution
• Redact — full block character replacement (█▓▒░)
• Stealth — subtle every-other-char swap for a natural-looking disguise

🎛️ FULLY CUSTOMISABLE
Choose exactly which fields to protect. Toggle sender names, subjects, email previews, recipients, attachments, CC/BCC, or body text independently. All settings sync instantly across sessions.

🌐 SUPPORTED MAIL SERVICES
• Gmail (mail.google.com)
• Outlook Live & Office 365
• Proton Mail

🔐 PRIVACY FIRST
PrivyShi reads no email content, sends no data anywhere, and requires no account or login. Everything runs 100% locally in your browser. No analytics, no tracking, no servers.

PERFECT FOR
Remote workers on video calls · Journalists and researchers · Shared computers · Open-plan offices · Screen recording and demos · Anyone who values inbox privacy
