ARX: data anonymization tool. Hides personal details in your datasets.

In simple English

This program helps you remove personal information from spreadsheets and databases. You load your data, choose how much privacy you need, and the software scrambles or groups the sensitive numbers and names. It keeps your files useful for research or sharing without revealing real people. You do not pay any money to use it. It runs on your own computer, so your secret data never leaves your hard drive.

What it is

ARX is an open-source data anonymization tool that runs on Java (a software platform needed to run certain programs on your computer). It includes a graphical user interface (a visual screen with buttons and menus you click with your mouse) so you can clean datasets without writing code.

What it is good for

Solo builders and researchers who need to publish user data, medical records, or customer lists while obeying privacy laws.

Good
  • Comes with a visual window so you do not need to write code.
  • Supports rigorous privacy rules like k-anonymity and differential privacy (a mathematical way to share information about a group without revealing details about any single person).
  • Free to use under the Apache-2.0 licence (a legal permit that lets you use and change software freely).
Watch for
  • Requires Java (a software platform needed to run certain programs) installed on your computer to work.
  • Large datasets can take up significant RAM (the computer memory used for running active programs) and slow down your machine.
  • Built as a research project, so user support is limited to community forums and documentation.
