Do you put your phone number on your resume?
Most people do. Because you want the recruiter to call you.
But here's the thing — when you send your resume, you're often sending more than just your phone number. Your home address. Maybe your date of birth. Sometimes a copy of your ID. The recruiter doesn't need any of that. But once you send it, you can't control where it goes.
Emails get sent to the wrong person. Files get forwarded. Attachments get saved, screenshotted, shared. You don't get a say after you hit send.
Redaction means removing or covering the things the other person doesn't need to see. It doesn't require special skills. But if you skip it, you're taking a risk that's completely unnecessary.
You might think you can just draw a black box over sensitive text and call it done.
That works for images. But if you're using Word, the text under that black box is still there. Someone can select it, copy it, and paste it somewhere else. The black box is just hiding it.
Word's Track Changes is another trap. You delete something, send the document, and the other person clicks "Accept All Changes" — your deleted text comes right back. It was never really gone.
PDFs have their own issues. Some people convert PDFs to images, then redact those. But PDFs often contain metadata — author names, company info, edit history. Things you don't see but are still there. Most people don't check metadata. But someone who knows where to look can find it.
"Free" online redaction tools make you upload your documents to their servers — exposing sensitive data before it's even redacted.
But what happens to your file after you upload it?
Some services keep copies. Some store them in plain text. Some use them to train their systems. If you're uploading a contract, a resume, or a scan of your ID, you're handing that data over to someone you don't know.
There have been cases where people uploaded documents to free tools, and those documents ended up in public databases. Not because the tool was malicious — because the company behind it didn't think about privacy.
If you don't know who runs the service, where the servers are, and what they do with your files, don't upload anything sensitive.
Not just ID numbers and bank details.
Certain pieces of information don't seem dangerous on their own. But combined, they paint a complete picture.
So keep it simple: give the recipient exactly what they need, nothing more. They need your phone number? Send that. They don't need your address or ID number? Leave it out.
The safest way to redact is to do it on your own machine. No uploads, no third-party servers, no copies sitting somewhere you can't delete.
