Sensitive Data Scrubber

Personally Identifiable Information (PII) is any data that could be used to identify a specific individual: names, email addresses, phone numbers, Social Security numbers, credit card numbers, IP addresses, and API credentials all qualify. Sharing PII carelessly in logs, bug reports, support tickets, or public forums can violate privacy regulations like GDPR, CCPA, and HIPAA, and can expose individuals to identity theft, phishing, and account takeover.

Developers routinely paste stack traces, server logs, and API responses into Slack channels, GitHub issues, and Stack Overflow questions without realising those snippets contain customer email addresses, authentication tokens, or internal IP addresses. Support agents forward email threads that include credit card numbers and phone numbers. Data analysts share sample datasets that contain Social Security numbers. In every case the intent is benign; the sensitive data is simply overlooked.

This tool solves the problem by scanning any text you paste and automatically replacing detected PII with clearly labelled placeholders like [EMAIL], [PHONE], [IP_ADDRESS], [CREDIT_CARD], [SSN], [API_KEY], and [JWT_TOKEN]. The scrubbing happens entirely in your browser using native JavaScript regular expressions, so no data is transmitted to any server, no copies are stored, and no third-party libraries are involved. You can toggle each PII category on or off independently, customise the placeholder text, and even add your own regex patterns for project-specific identifiers.

Whether you are sanitising logs before pasting them into a public issue tracker, preparing a dataset for sharing with a contractor, or simply double-checking an email draft for accidental PII leakage, this tool gives you a fast, private, and transparent way to scrub sensitive data before it leaves your machine.
