USE CASE
Check a web form for personal or confidential data before you submit it
Check for email addresses, phone numbers or project names left in text before submitting a form or posting to an internal tool. This guide shows how to use Safe Privacy Gate.
This extension does not prevent data leaks. It reports matches and pauses the current submission so you can check. It does not rewrite your text or decide whether it is safe to send. You make that decision.
Pasted text can include details you did not mean to share
Filling in a form, you read the dedicated fields carefully — your name, your email address. The one that slips past is the free-text box.
Paste in an old email or chat log and, along with the part you needed, someone else’s email address, a phone number, a customer number or a project name can come with it.
The longer the text gets, the less likely you are to read the whole thing again before pressing send.
Forms may submit without another check
An ordinary web form does not necessarily give you a second look at what you wrote. Whether you check, and how much of it you check, is left to the sender.
- Reading pasted text from the top again, on every send
- Reading it and still skimming past the parts you did not type yourself
Information copied from elsewhere can be easy to overlook. Safe Privacy Gate checks it just before you send.
The same job with Safe Privacy Gate
- 1
Fill in the form exactly as you normally would.
- 2
Press “send”.
- 3
If nothing it watches for is there, the form submits as usual.
- 4
If it finds an email address, a phone number or something similar, it pauses that send and shows you.
- 5
You decide whether to edit the text or send it as it is.
Safe Privacy Gate never changes your text on its own.
These are the shapes it looks for in that last moment.
A plain Enter is treated as a line break and is not stopped (on AI chats where Enter sends, Enter counts as a send). For attachments it reads the file name only, never the contents.
What this looks like in practice
Pasting an old email into a contact form
You quote the message to explain the situation, and the sender’s address is still in the quote.
Copying a customer exchange into an internal tool
You meant to share only the relevant part, and the customer’s phone number and reference numbers came along.
Checking the name of an attachment
You checked what was inside the file, and the customer or project name was still in its file name.
Watching for words only your organisation uses
Employee numbers, project codes and confidential project names, registered as custom rules and checked the same way.
What Safe Privacy Gate does
- Checks what you wrote in the moment before it is sent
- Detects the shape of email addresses, phone numbers, API keys and the like
- Lets you add your own words and formats as rules
- Checks the file name of an attachment
- Keeps the whole check inside your browser
What Safe Privacy Gate does not do
- Prevent a leak completely
- Rewrite what you wrote, automatically
- Decide for you whether something may be sent
- Replace your organisation’s DLP or its approval process
The extension does not prohibit sending. It gives you a chance to review the content just before you send.
