Does ScrubLocal upload my logs, HAR files, or CSVs to a server?

No. ScrubLocal runs 100% inside your web browser. Zero network requests are sent when you paste text or select a file, and you can use the tool completely offline after loading the page.

How does reversible AI sanitization work?

When ScrubLocal redacts sensitive values, it replaces every occurrence deterministically (for example, alice@acme.com becomes [EMAIL_1] everywhere) and stores the mapping in your browser memory. After ChatGPT or Claude responds using those placeholders, paste the AI response into the Restore AI Reply tab to swap the real values back in locally.

How do I sanitize a Chrome DevTools HAR file before sending it to support?

Upload or paste your .har file into ScrubLocal. It automatically strips Authorization Bearer tokens, Cookie and Set-Cookie headers, x-api-key values, emails, and IPv4 addresses while keeping the JSON structure intact.

Sanitize Sensitive Files Locally Before Sharing with AI or Support

Pasting raw production logs, customer CSVs, or Chrome DevTools HAR captures into LLMs or support tickets risks leaking credentials and customer PII. ScrubLocal replaces every sensitive token deterministically inside your browser and lets you restore original values when the AI replies.

Does ScrubLocal ever send my data to a server?

Never. All pattern detection, redaction, and token restoration execute inside your browser tab. If you open your browser's Network inspector or disconnect from Wi-Fi after loading the page, ScrubLocal continues to work with zero outbound traffic.

How does the reversible AI round-trip work?

Each unique email, IP, secret, or custom word is mapped to a numbered placeholder such as [EMAIL_1] or [SECRET_1] in browser memory. When you paste an answer from ChatGPT or Claude into the Restore AI Reply tab, ScrubLocal swaps the real values back in locally.

How does ScrubLocal avoid false positives on order numbers?

13-to-19 digit sequences are checked against the Luhn checksum algorithm before being flagged as credit card numbers, leaving non-Luhn order IDs and timestamps intact.

What happens to my token vault when I close the tab?

Your replacement map lives strictly in volatile browser memory and is erased the moment you close or refresh the tab.
