Alumni anonymisation is the removal of personal identifiers from a former-staff contact set under UK GDPR Art. 17. The article lets a person demand erasure of their data. anonym.plus marks names, e-mails, and contacts on your device, so aggregate trends survive while the individuals behind them disappear.
When this applies
An alumni list holds names, personal e-mails, and last roles. You anonymise it so the firm can keep trend data without holding identifiable former-staff records.
How anonym.plus handles it
- Open the list in anonym.plus on your device.
- The tool flags names, personal e-mails, and phones.
- Local OCR reads a scanned roster page.
- Keep the year-band and role columns for trends.
- Replace each identifier, with the name map off.
- Save the clean set locally.
What you need to provide
- The alumni list (CSV, XLSX export, PDF).
- An operator (Replace, with the name map turned OFF).
- Optional allow-list for year-band columns.

Limitations & cautions
True anonymity needs the reversible name map turned off; leave it on and the set can be re-linked. A rare role in a small year-band can still single out a person, so band such fields before you keep the file.
Frequently asked questions
How do I make alumni data truly anonymous?
Turn the name map OFF and use Replace. With no stored mapping, the identifiers cannot be restored, which supports retention under Art. 17.
Can a year and role still identify an alum?
In a small cohort, yes. Band the leaving year and group rare roles so one row cannot name a person.
Is the roster uploaded?
No. The app runs offline, so the set stays on your machine.
