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.
Where it helps
| Task | How PII Shield helps |
|---|---|
| Asking an AI tool about a case | De-identify the note first, use the AI on the de-identified text, restore details locally. |
| Sharing records for referral or research | Strip PHI with a reviewed, consistent pass before the file leaves the practice. |
| Session & consultation recordings | Transcribe and redact audio locally — names, numbers and identifiers bleeped. |
| Data-subject / access requests | Remove 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.
Frequently asked questions
Remove the identifiers first. PII Shield de-identifies protected health information locally, so you can use an AI tool on the de-identified version and restore the details on your own machine. The identifiable data never leaves your computer.

Yes. It handles documents, spreadsheets and email, and it can transcribe and redact audio such as therapy or consultation recordings — all locally.
Compliance is a property of your organisation and processes, not a single tool. Because PII Shield never receives your data, there is no business-associate relationship to manage with us; it is a local tool that helps you de-identify data. It is not legal or compliance advice.
Yes. A mapping stored on your device lets you restore the original values when you need the complete record.
