Most of what an author reaches for is evidence they could have made last night.
Every file you submit gets a cryptographic fingerprint. Change one pixel of the cover and the fingerprint changes. We record the fingerprints; your files themselves are never published.
Those fingerprints are gathered into one manifest and anchored into the Bitcoin blockchain through OpenTimestamps. Your date is fixed by a block, not by a row in our database.
Your files are held under a seven-year object lock. The key our own servers run on is not permitted to delete them — a system that writes the evidence must not be able to destroy it.
Your proof does not depend on us staying in business.
Download the proof file from your certificate, take it to opentimestamps.org — a site we do not run — and it verifies against Bitcoin with no Puzzles Almanac server alive. The subscription witnessing services cannot say that. When they close, their certificates quietly become PDFs.
Every certificate can be checked without us
A certificate has a public page and a downloadable proof. The reviewer needs no account, and the last step happens on somebody else's website.
If an author has sent you a reference and a verification password, look the record up directly. Nothing about it goes through them.
Verify a certificateNot a concept — the attachments you put in the reply.
Reference, registrant name, issue date and every file fingerprint on one document a reviewer can read in twenty seconds.
Share it and the reviewer checks the record themselves — no account, no login, nothing routed back through you.
The exact bytes the timestamp commits to, so anyone technical can re-derive the whole chain from your files down to the block.
For your copyright page. The cheapest complaint to survive is the one nobody bothers to file — scrapers pick easier targets.
A reply to the review team, a notice to the other party, a counter-notice. Drafted entirely in your browser — we never receive the other side's name.
The letters are drafting templates we wrote, not legal advice, and we are not your lawyers. For anything contested, take them to one.
What Guard does not do
A timestamp proves that specific files existed, under your name, on a specific date. Authorship is a separate question, and no timestamp anywhere settles it.
It is evidence, not a government record. Copyright begins the moment you create an original work, and if a title is worth registering with a copyright office, register it — Guard sits alongside that, never instead of it.
Every case is decided by Amazon's reviewer, not by us. Anyone guaranteeing you a result is selling something they do not control.
We would rather you learn the limits here, in a calm moment, than discover them on day three of a five-day window.
A certificate is worth exactly
what its date is worth
Issued today, it proves today. Issued the week after someone reported you, it proves the week after someone reported you — and the other side will point that out. There is no retroactive version of this for sale anywhere, which is the entire reason to do it while nothing is wrong.
There is no per-certificate price
Guard is not sold by the unit. Access comes with a seat in Royalty Guild — where the authors dealing with this are already comparing notes — and your first certificate is free when you arrive.

One book, five minutes, no card. If the notice never comes, you have lost an afternoon. If it does, you already hold the one thing you cannot make later.
