Anonymize nginx access logs

Access logs are personal data under GDPR and the Philippine Data Privacy Act: every line starts with a client IP, and query strings often carry tokens and emails. ScrubLogs masks them consistently, so traffic patterns survive and identities don’t.

Runs 100% in your browser. Nothing is uploaded.

What usually leaks

Client IPv4 and IPv6 addresses
Tokens and API keys in query strings
Emails in reset and signup URLs
Upstream hosts and internal IPs in error logs

Tips

Consistent placeholders let you still count requests per client: every hit from <IP_3> came from the same address.
Large logs: drop the file onto the tool. Files up to 10 MB are processed in your browser.
