Seal the Offer Before You Book

Seal the Offer Before You Book### Preserve the details your booking decision is based on.

You find the perfect holiday apartment online.

The photos look great. The location is ideal. The listing promises air conditioning, a private parking space, sea views, free Wi-Fi, and flexible cancellation.

Those details make the difference, so you book the apartment and pay.

Several weeks later, you arrive.

There is no air conditioning. Parking costs extra. The promised sea view is blocked by another building.

You open the listing again, but some of the details have changed — or the original offer is no longer available.

Your booking confirmation shows the dates and the amount you paid. It may not contain every feature and promise that influenced your decision.

Now you wish you had preserved the complete offer before booking.

A screenshot is useful — but limited

You could take screenshots of every important webpage. That is better than having no record at all.

However, an ordinary screenshot can be edited. It does not provide an independent timestamp, and another person cannot easily determine whether it still contains the original pixels.

This is where Beaver Page Proof comes in.

Before booking, buying, travelling, or making another important decision, you open the offer in Beaver Page Proof and seal the webpage.

The app creates a proof package containing the captured page and the information required for later verification.

What the proof establishes

The sealed package preserves the webpage as it appeared when you created the proof.

Later verification can establish two important facts:

  • The sealed content existed by the confirmed timestamp.
  • The content inside the proof package has not been changed afterward. Even the smallest modification produces a different digital fingerprint and causes verification to fail.

The proof does not determine whether every statement on the webpage was true. It does not decide who is legally responsible or replace professional advice.

It preserves the information that was presented to you when you made your decision.

Verification is separate and free

A proof should not depend solely on the person who created it.

That is why Beaver Proof Verifier is a separate, free app. You can send the proof package to another person — a business, adviser, insurer, or lawyer — and they can verify it independently.

No Beaver account is required.

The timestamp is created through the open OpenTimestamps protocol and anchored to the Bitcoin blockchain. Beaver Proof does not upload the captured document or webpage to the blockchain. Only a cryptographic fingerprint becomes part of the timestamping process.

Your private content remains inside your proof package.

More than holiday bookings

The same principle applies whenever online information influences a later decision:

  • Product descriptions and condition statements
  • Used-item listings that disappear after a sale
  • Warranty and compatibility promises
  • Course contents and access commitments
  • Rental property descriptions
  • Service packages and advertised features
  • Competition rules and participation conditions
  • Public notices and published statements The right moment to preserve an offer is not after a disagreement begins.

It is before you rely on it.

Preserve first. Verify later.

Webpages are designed to change. Offers are updated, listings expire, and details can be removed.

Beaver Page Proof gives you a simple way to preserve the online information behind an important decision.

Before you book, buy, travel, or commit: seal the page.
