De-identify patient data for healthcare & therapists

Patient records are the most sensitive data there is. PII Shield lets clinics, private practices and therapists remove protected health information locally before using AI or sharing a file, and restore it afterwards — so identifiable patient data never leaves the device.

In short. Open a record or recording in PII Shield. It detects names, dates of birth, contact details, IDs and medical record numbers on your computer, lets you redact them in a quick review, and keeps a local mapping so you can restore the original when needed. Nothing is uploaded.

Where it helps

TaskHow PII Shield helps
Asking an AI tool about a caseDe-identify the note first, use the AI on the de-identified text, restore details locally.
Sharing records for referral or researchStrip PHI with a reviewed, consistent pass before the file leaves the practice.
Session & consultation recordingsTranscribe and redact audio locally — names, numbers and identifiers bleeped.
Data-subject / access requestsRemove other people’s data before releasing records.

Why on-device matters for PHI

Sending patient data to a cloud service means a third party now holds identifiable health information, with all the transfer, retention and processing questions that follow. PII Shield keeps the whole process on the machine you already control: no account, no upload, no telemetry by default. Because your data never reaches us, there is no business-associate agreement to manage with us. See exactly what stays on your device on the Data & Privacy Practices page.

A tool, with you in control

Detection combines an AI model with precise pattern rules, and you confirm every item before it is redacted. PII Shield is a tool to help you de-identify data — not legal or compliance advice, and not a substitute for your organisation’s own safeguards.
