You can redact any message sent using the application. Tap the redact button and the message is instantly redacted from your phone. The message is also redacted on your contact's device. There's no way to refuse a redaction or avoid it, so you can be confident your message is deleted forever.

All instant messaging apps store messages you're sending to your contacts. No matter how securely these messages are saved, they're vulnerable to hackers or government subpoenas. Redact stores no messages, contact information or usernames so there is no information to be stolen.
Redact never asks for a username, email or phone number, you're automatically assigned a PIN. Your unique number is never stored anywhere, and there is no recovery tool for hackers to exploit. Only you can change your alias, so you can be certain contacts aren't using your real name anywhere in the application.
