This tool is provided as-is for convenience. While it aims to detect and redact common sensitive patterns, it:
- Does NOT guarantee 100% detection of all sensitive data
- Should NOT be your only layer of review before sharing logs externally
- Relies on pattern matching and may have false positives/negatives
- User is SOLELY responsible for reviewing redacted logs before sharing
- User is SOLELY responsible for ensuring compliance with data protection laws
- Cannot detect proprietary or custom sensitive data formats
- Should ALWAYS be followed by manual review of critical logs
We make NO WARRANTY about the accuracy, reliability, or completeness of redactions.
Users should ALWAYS:
- Review the diff view before copying
- Manually check for missed sensitive data
- Test with non-production logs first
- Use this as a HELPER TOOL, not a replacement for security review
The creator (johlem.net) is not liable for data breaches or leaks resulting from missed redactions, false positives or false negatives in pattern detection, damage to reputation or systems caused by tool usage, or compliance violations due to inadequate redaction. By using this tool, you accept full responsibility for your redaction accuracy.
