If you work with ncurses, you know how fast it is to build text-based UIs. But GDPR compliance doesn’t care about speed. It cares about the who, what, where, and why of the data you touch. You can’t let personally identifiable information leak in logs, scrollbacks, or debug dumps. And you can’t store it without purpose, consent, and a plan to delete it when you’re supposed to.
GDPR requirements don’t change for a non-graphical interface. Whether you’re sending output to a pixel-rich SPA or a pure ncurses console, the data lifecycle is the same. Step one: know what user data flows through your app. Step two: keep it encrypted in transit and at rest. Step three: cut it off at the source if you don’t need it. In an ncurses app, that might mean masking input in real time, wiping memory buffers after use, and logging only anonymized or aggregated values.
Audit every data path. Run checks on how your ncurses code writes to temp files, pipes, or other subsystems. Most GDPR breaches aren’t from big hacks—they come from cached files no one remembered were there. It’s also critical to handle right-to-access, right-to-rectify, and right-to-be-forgotten requests without manual firefighting. That means designing for compliance from the first line of code.
