Seal the exact text of a quote, a promise, or agreed terms before you send it. Independently timestamped, so if someone later claims you said something different, there is a real answer, not just your word against theirs.
How this actually works
Your browser hashes the text before anything is sent, so Red Flag never receives or stores what you actually wrote, only its fingerprint. That fingerprint is sent to an independent third party (an RFC 3161 Time Stamping Authority) that certifies it existed at a specific moment, not Red Flag on its own.
To verify later, paste the same text back in with the Seal ID. If even one character has changed, it will not match.
