Alumni anonymisation is the removal of personal identifiers from a former-staff contact set under GDPR Art. 17. The article lets a person demand erasure of their data. anonym.plus marks names, emails, and contacts on your device, so aggregate trends survive while the individuals behind them disappear.
When this applies
An alumni list holds names, personal emails, 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 app flags names, personal emails, 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.
