Privera.

Automatic redaction of sensitive data in PDF and Word documents. On your computer, never in the cloud.

What it is

Redaction without the busywork

Anonymizing a legal document by hand means reading every line, hunting for names, personal numbers and addresses, and hoping you did not miss one. Privera does that work for you. Open a file, and it finds the sensitive information automatically: names, personnummer, addresses, phone numbers, emails, bank details.

You stay in control. Every detection is shown for review before anything is masked, and the finished document is exported with the sensitive pixels actually removed, not just covered up. Nothing is uploaded anywhere. The entire process runs on your own machine.

Who it's for

Built for people who handle sensitive documents

Law firms

Redact privileged material for court filings, discovery and client sharing without letting it leave the firm.

HR, finance & public sector

Anonymize employment records, invoices and case files before archiving or handing them out.

Anyone under GDPR

Large document volumes take hours to handle manually. Privera batch-processes up to 100 files at a time, locally.

From Privera's launch campaign: large document volumes take hours to handle manually. Privera batch-processes up to 100 files at a time, entirely locally.

Privera's review view: detected sensitive data grouped by category, ready to mask

The document renders in the center with every hit color-coded and grouped by category on the right. Toggle categories, click a hit to exclude it, or draw your own redactions. Then export a clean file. Try it at privera.se ↗

How it works

Three engines, one clean result

Detect. Three engines read the document together. Regex with Luhn checksum validation catches structured identifiers like personnummer and IBAN. Dedicated patterns catch phone numbers and emails. KB-BERT, a Swedish language model from the National Library, finds names, organisations and places. Scanned documents fall back to Tesseract OCR automatically.

Propagate. When a name is found once, it is masked everywhere, including a signature on the last page that the model only tagged on page one. Addresses grow to cover house numbers and postcodes, even when they wrap across a line break.

Redact, for real. Most tools draw a black box over the text. Privera removes the underlying pixels, so the content cannot be recovered by copy-paste or forensic tools.

Prove it. Every run writes an audit file with SHA-256 hashes of input and output, a tamper-evident log for GDPR compliance. The whole pipeline is covered by 179 automated tests.

Why local-first matters: competing tools upload documents to the cloud. Privera runs everything on the user's own machine. No account, no telemetry, nothing leaves the firm. For privileged legal material, that is the whole point.
