Redaction Software That Never Uploads Your Documents
Automatic redaction software for Mac. Sensitive data is detected, reviewed and permanently removed — entirely on your device. No cloud processing, no per-seat contract, no Adobe subscription.
Get BlurData for Mac Compare optionsWhat proper redaction software actually does
Drawing a black rectangle over text in an ordinary editor is not redaction — in many formats the original text is still in the file, one copy-paste away from being exposed. Court filings and government releases have leaked names exactly this way. Real redaction software removes the underlying data: exported images have the cover rendered into the pixels, and exported PDFs have the sensitive text taken out of the document itself.
The second thing that separates redaction software from a drawing tool is detection. On a 60-page document, "look carefully and box everything yourself" is where mistakes happen. BlurData finds emails, names, addresses, account numbers and more automatically, shows you every match, and lets you decide what gets removed.

Frequently asked questions
What is redaction software?
Redaction software permanently removes sensitive information — names, emails, account numbers, addresses — from documents before they are shared. Proper redaction software deletes the underlying data, not just covers it: a black rectangle drawn over text in a regular editor can often be removed to reveal the original.
What makes BlurData different from enterprise redaction software?
Enterprise redaction platforms are priced per-seat per-month and typically process your documents in the cloud. BlurData runs entirely on your Mac — documents never leave your device — and costs $79/year or $149 one-time. You get automatic detection without an enterprise contract.
Does BlurData redact automatically or manually?
Both. BlurData automatically detects 8 categories of sensitive data and lets you add custom patterns. You review the detections, adjust anything, then export. You can also redact any word manually with a double-click. And if your document type needs a dedicated preset, request it — presets are typically built and shipped within 24 hours.
Is the redaction permanent and secure?
Yes. Exported images have redactions rendered into the pixels, and exported PDFs have the sensitive text removed from the document itself — not hidden under a box. There is no way to recover redacted content from the exported file.
Does redaction software need an internet connection?
Cloud-based redaction services do — which means uploading the very documents you're trying to protect. BlurData is fully offline: detection and export run on your Mac with no upload, no account, and no telemetry on your documents.
