How are credit card numbers verified?

The tool uses the Luhn checksum formula (MOD 10) to distinguish genuine payment card numbers from random digit sequences, preventing false positives on product SKUs or serial numbers.

Can I reverse the sanitization later?

Yes. If you choose the numbered token mode ([EMAIL_1], [API_KEY_1]), you can export a client-side JSON token mapping file that allows you to restore original values locally when needed.

Which API keys and secrets are automatically detected?

AWS Access Keys (AKIA/ABIA), OpenAI secret keys (sk-...), GitHub tokens (ghp/gho), JWT authentication tokens, Slack webhooks, and private credentials.

Cleaned & Sanitized Output

Subject: Incident Report #4921 - Customer Support Escalation

Hi team,

Customer Alice Walker (email: [EMAIL_1], cell: [PHONE_1]) reported an authentication error on server [IP_1] and IPv6 [IP_2].
During debugging, the staging API key was accidentally printed in the logs:
AWS_ACCESS_KEY: [API_KEY_1]
OpenAI Key: [API_KEY_2]
JWT Token: [API_KEY_3]

Her recorded SSN on file is [SSN_1] and the corporate billing card was [PHONE_2]-5678 (Visa).
Please scrub this data before archiving to the public audit bucket.

Regards,
Security Operations
[EMAIL_2]

Free Client-Side PII & Data Scrubber — Zero Data Leaves Your Device

Why we built this: When debugging production crashes, sharing error logs with AI chatbots, or publishing database dumps, developers and support engineers regularly leak customer emails, phone numbers, API keys, and payment credentials. Cloud-based sanitizers defeat the purpose by uploading your secrets to yet another third party. We built this PII scrubber to sanitize text 100% in-browser.

How it works: 1) Paste your logs, chat transcripts, or SQL dumps (or drop a .txt, .csv, .log, or .json file). 2) Our client-side detection engine identifies emails, international phone numbers, Luhn-verified credit cards, IPv4/IPv6 addresses, API keys (AWS, OpenAI, GitHub tokens, JWTs), and SSNs. 3) Choose your masking mode (numbered tokens, generic [REDACTED], or asterisks), and copy the cleaned text or download the reversible token mapping table.

All pattern recognition and checksum validations execute locally in your browser memory. Token mappings are reversible only on your local machine, allowing you to de-anonymize data later without risking external leaks.

Frequently Asked Questions

Everything you need to know about using Client-Side PII & Data Scrubber safely and efficiently.

No. The entire sanitization process runs 100% client-side in your browser JavaScript memory. You can use this tool completely offline without an internet connection.
