I removed the name. Is the report anonymous?

No. A date of birth, a town, a rare condition can still single a person out, and the draft HAS-CNIL guidance says exactly that about a patient's medical history. So Anoni shows a re-identification risk after redaction, in plain words and with no percentage. Read it over before you send.

I have an AI write up my reports. Same problem?

Yes, and it is the most common use of all. Anoni does not transcribe: it works on the text. Pseudonymize the report before you hand it to the AI, decode the reply afterwards. The patient never appears.

Clearer letters. Protected patients.

Prepare your text before using AI. Identify personal data and check what the remaining context could reveal.

Follow-up letter

For the attention of Claire Fontaine: please send the requested documents before your next appointment. Our reception team is available to help.

One name illustrated. Always review the full export.

In practice

Rephrase an administrative letter

Improve the clarity of a message after reviewing its sensitive data.

A pseudonym may not be enough: medical information and context can still identify a patient.

A clinical report, a letter, a result. PDF, DOCX, Excel, email, TXT, Markdown, CSV or image. Nothing leaves your machine.

Every day

Every part of the file deserves care.

Patient identifiers

The NIR social-security number, a date of birth in digits or spelled out, an address, a town. Plus the hospital patient id or file number, recognized by its label, never from a bare number.

Re-identification risk

After redaction, Anoni flags what can still single someone out: date of birth, age, role, precise location, health data. A plain-language assessment, never a percentage.

Scanned documents

Local OCR reads a scanned PDF or a photo. When there is no text at all, you draw the black zones by hand: a signature, a stamp, a photo.

Reference points

Your professional framework.

Sources: article 4 of the French medical code of conduct · HAS (October 2025) · draft HAS-CNIL guidance (February 2026), a working draft dated 16 February 2026, open for public consultation until 16 April 2026. These sources are in French.

Going further: what the CNIL means by pseudonymization and anonymization.

Article L. 1110-4 of the French public health code: the duty covers all information concerning the person, and binds every professional in the health system. A name or an address counts as much as a diagnosis.

Questions

Before your first document.

Hosting health data with a third party requires that third party to be a certified health-data host (HDS) and to store the data inside the European Economic Area (article L. 1111-8 of the French public health code). Anoni hosts nothing: the document stays on your machine. Anoni is not a certified host, and it does not make any other tool compliant on your behalf.
