PrivacyBlur Plus helps prevent accidental exposure of sensitive information while users share, record, stream, teach, demonstrate, or present from their browser.
All detection heuristics, regex pattern matching, and visual masking execute entirely within your local browser runtime. Zero external API calls, zero tracking, and zero telemetry.
Instead of creating hundreds of slow absolute DOM overlay divs, PrivacyBlur Plus uses browser-native ::highlight() for silky 60fps scrolling and zero layout reflow.
Never mutates real input values (e.g. input.value). Forms remain 100% submittable, and React, Vue, and Angular SPA states remain completely untouched.
Validates Visa, Mastercard, Amex, and Discover numbers using mathematical Mod-10 checksums, alongside contextual CVV/expiry date filters to prevent false positives.
Easily define sensitive internal project codenames, client identifiers, or custom regular expressions. Built-in zero-length loop guards ensure ultra-safe matching.
Click any element, highlight text, or drag an area box over entire dashboard regions to instantly mask confidential content with exact URL or domain-scoped rules.
