Progress note de-identification is the removal of personal data from a clinician’s ongoing notes. UK GDPR Art. 9 and DPA 2018 govern special-category health data. anonym.plus does it on your machine. The update stays readable; the client is not named.
When this applies
You track outcomes across many visits. To pool the text safely, names, dates, and IDs must be stripped from every entry first.
How anonym.plus handles it
- Open the file in anonym.plus on your own device.
- Local OCR reads any scanned page.
- It marks names, dates, and ID numbers.
- Review each flag and keep the clinical update.
- Replace each identifier with a label, or black it out.
- Save the clean entry. The source stays local.
What you need to provide
- The file (PDF, DOCX, TXT, or scan).
- An operator: Replace, Redact, or Mask.
- Optional: a name map for re-linking.

Limitations & cautions
UK GDPR also expects no leftover clue that could re-identify the person. The tool clears named identifiers. A vivid one-off event in the text may still hint at identity, so review before sharing.
Frequently asked questions
Can I batch many notes?
Yes. Process each file in turn with the same operator. Use a shared key map if you need to keep entries linked across visits.
Are partners and family hidden?
Yes. A named partner or relative is an identifier. The tool flags each so the client cannot be traced through them.
Is the file uploaded?
No. The app works on your own device. Nothing is sent to a server.
