Sharefrost – Blur & Hide Sensitive Info When Screen Sharing

One hotkey blurs or redacts emails, names, card numbers, API keys and CRM columns before you share your screen. Processed locally.

Share your screen. Not your customers. Sharefrost blurs or redacts sensitive information on any web page with one hotkey, before you share your screen on Zoom, Google Meet or Microsoft Teams. Emails, phone numbers, customer names, card numbers, API keys and whole CRM columns disappear behind a clean bar. A pre-flight check tells you when the page is safe to share. Everything is processed locally in your browser: nothing on the page is ever sent anywhere. ━━ HOW IT WORKS ━━ 1. Press Alt+Shift+S (⌥⇧S on Mac) to turn on Share Mode for the tab you are about to share. 2. Personal data is covered at once. Pick a style: redact (a solid bar, the default for personal data), blur, pixelate or hide. 3. Press Alt+Shift+C to run the pre-flight check. It counts anything still visible and covers it in one click. 4. Share your screen, record a demo or take a screenshot without exposing anyone's data. ━━ DETECTED AUTOMATICALLY ━━ • Email addresses and phone numbers • Credit and debit card numbers (checksum-verified, so order numbers are left alone) • IBANs, bank account and routing numbers • Social Security numbers and other government ID numbers • API keys, access tokens, passwords, one-time codes and private links • Postal addresses, customer names and dates of birth • IP addresses and crypto wallet addresses • Optional: money amounts, usernames, order numbers, profile photos and GPS coordinates Each detector can be switched on or off. ━━ COVER ANYTHING ELSE ━━ • Click any element to mask it, or a whole table column in one click • Drag a box to blur any area: charts, video, canvas apps • Custom rules with keywords or regular expressions, plus an allow-list • Save rules for one page, a path or a whole site; they apply before the page is drawn • Import and export your rules as JSON • Ready-made templates for 15 popular CRM, help desk, email, payments and analytics apps, including Salesforce and HubSpot ━━ BUILT FOR CALLS, DEMOS AND SCREEN RECORDINGS ━━ • Pre-flight check: "2 items still visible", fixed in one click • Audience preview: see exactly what your viewers will see • Clean Share Window: move the tab into a window with no bookmarks bar and no other tabs • Mask the tab title and favicon while you share • Peek: check a hidden value yourself in the side panel; it never appears on the shared page ━━ PRIVACY ━━ • Nothing on the page leaves your browser. Page text, URLs and the values Sharefrost covers are never sent to any server. • No analytics and no tracking. • Site access is requested one site at a time, only when you save rules for that site. • If you create an account, it stores your email address and your rule definitions so they can sync. Nothing else. ━━ PRICING ━━ Free for individuals, with every feature and no limits on sites or templates. After 10 sessions, a free account (Google or email) is needed to keep using Share Mode. The account adds sync across devices, backup and restore, and team invites. A paid Team plan with shared, lockable rule sets is planned. ━━ KEYBOARD SHORTCUTS ━━ Alt+Shift+S: turn Share Mode on or off Alt+Shift+C: run the pre-flight check Alt+Shift+P: peek at a hidden value (10 seconds) Alt+Shift+V: move focus to the Sharefrost toolbar Change them at chrome://extensions/shortcuts ━━ GOOD TO KNOW ━━ • Text drawn on a canvas (some spreadsheet grids and whiteboard apps) can't be read; use the area tool there. • Chrome's own pages (chrome://, the Chrome Web Store) and the built-in PDF viewer can't be changed by any extension. • Sharefrost never edits what you type; it only covers what is shown.
