How can I check the page is really sealed?

Open the "Sealed page" button at the top. It tries to send data, send a background ping and contact another website, and each check only passes if your browser itself refuses. You can also open your browser's developer tools: the Network tab stays empty while you scrub.

Email addresses, phone numbers, US Social Security numbers, credit card numbers, IPv4 and IPv6 addresses, dates, street addresses, URLs, MAC addresses, passport and driver's license numbers, API keys and tokens (OpenAI, AWS, GitHub, GitLab, Slack and generic key=value secrets), and private or encryption keys. Personal names can be enabled too; that pattern is a guess, so it is off by default.

Anything that does not follow a common format: a nickname, a date written in words, an ID number in an unusual layout, a phone number without separators from a country it does not know. Read the result before sharing it; the tool shows a log of exactly what it changed and lets you put any item back.

PII scrubber — redact emails, phone numbers, card numbers and API keys on a sealed page that can't send data

Q: Is the text I paste uploaded anywhere?

No, and it can't be. The scrubber runs on its own sealed page: it loads no analytics and no outside code, and its security policy tells your browser to refuse every network request the page makes. The page shows your browser testing that seal when you arrive. The pasted text is not saved either, and it is wiped when you leave.

Clean personal information out of text before you share it with a chatbot, a coworker, a forum or a bug report. Paste, click Scrub, copy the result. This page can't send what you paste anywhere, and it shows you why.

🔒 Why This Page Is Sealed

The rest of Snagmoji counts visits with Fathom. This page doesn't load it, or anything else from outside the site. Its security policy also tells your browser to refuse every network request the page tries to make, so even a bug in our own code couldn't send your text anywhere.

The Sealed page button runs the proof: it tries to send data, send a background ping and reach another website, and shows a ✔ only when your browser refuses. Your pasted text is never saved, and it's wiped when you leave the page.

One honest limit: browser extensions you've installed can see every page, this one included. For maximum privacy, disable your extensions first, or open this page in a private window, where most browsers switch them off.
