Your device computes the hash. Our server signs the hash and the time — never the content. Nothing you drop here is uploaded anywhere.

Why this matters

That receipt is self-contained. Anyone can check it at lowlaws.com/verify without an account, without trusting us, and even if LOWLAW no longer exists — because we signed a hash, not your content.

🟠 Prototype signing key

This build signs with a demo key that is published in the open source, so anyone can reproduce it. Receipts issued now prove the mechanism works — they carry no weight, and they stop verifying when the key is rotated to a hardware-backed one before real use. We would rather say this than let a receipt imply more than it proves.

🟠 What a seal proves, and what it doesn't

It proves this exact content existed at this exact moment, and hasn't changed since. It says nothing about whether the content is true — same as a notary, and we will never imply otherwise.
