PII redaction that never phones home

Why local matters for PII

There is an obvious contradiction in sending your most sensitive data to a third-party cloud service in order to have that data 'protected'. Every upload is a new copy, a new log, and a new attack surface.

DataAnonymiser keeps the whole job on-device: finding the identifiers, replacing them, and the mapping that reverses it. Nothing about your content is transmitted, and there are no server-side logs to leak.

What it detects

DataAnonymiser identifies names, email addresses, phone numbers, physical addresses, government and financial identifiers, and health details across both text and images. Each detected identifier is replaced with a consistent placeholder, and you can add custom keywords for terms specific to your organisation.

Detection is best-effort, no tool catches every identifier in every phrasing, so DataAnonymiser also produces a residual-risk report for a human to review before the output is shared.

Works offline after activation

Once your subscription is activated and the app has finished setting itself up, redaction works without a network connection. An internet link is only needed for account activation, downloads, and updates, never for the anonymisation itself.
