Hide Sensitive Information
Mask emails and phone numbers in one pass.
Hide Sensitive Information is a browser-based text tool on TextToolsBase. Mask emails and phone numbers in one pass. To use it, paste or type your text and view the result directly in your browser — no signup and nothing to install.
Quotes from real correspondence usually contain both email addresses and phone numbers, and hiding them one type at a time is slow.
Hide Sensitive Information masks emails and phone numbers together, each with a simple on switch.

Use cases

Good to know
Hide Sensitive Information combines two detectors: email masking, which keeps the first letter and masks the rest, and phone masking, which hides the digits. Each is an independent switch so you can mask one type or both. As with the other privacy tools, detection runs entirely in your browser.
Frequently asked questions
What does it hide?
Email addresses and phone numbers, each controlled by its own switch so you can mask either or both.
How are the emails masked here?
The first letter of the address is kept and the rest of the name and domain are masked, with the extension left readable.
Does it detect names or other details?
No. This tool targets emails and phone numbers; use the anonymize tool to also replace names and long numbers.
