Why WorkLens

Three things no other privacy-safe data tool can claim — and you can verify each one.

Zero Network Requests

Open DevTools. Generate or redact a file. Watch the Network tab — zero outbound requests. Your data never touches a server. Prove it yourself.

Mathematically Verified

Every ID number — TFN, Medicare, ABN, credit cards — is validated using official mathematical checks, not guessed. Works globally with deep Australian support. More regions coming.

Audit Receipt

Every job — generate or redact — produces a signed fingerprint that proves what happened. If anything is altered, the signature won't match.

Prove It Yourself

No other privacy-safe data tool can pass this test.

Open Chrome DevTools (F12) → Network tab

Generate or redact any file

Watch the Network tab — zero outbound requests

Turn off your WiFi — try another job. It still works.

Your file never left your machine — even offline.
