airproof - secure your stay

Bullet-proof security with the push of a button!

Welcome to airproof - the easiest way to secure your stay at a private rental.

  • prove you left a clean apartment

  • prove the exact time you left

  • prove where you left the key

  • prevent arguments with the host

  • ... all in an easy to use smartphone app!

    What makes airproof so secure?

    An airproof is a video you take when checking out of your private rental - with blockchain security built in.

    airproof uses the cryptographic security of the blockchain to provide highly secure, but very cost effective “proof of existence” for your airproof video.

    airproof is extremely easy to use.

    All you have to do is take a video with the airproof app when you are checking in or checking out of the rented apartment. It is as easy as using the built-in camera - all the security features are added automatically in the background.

    Whenever you need to make use of your airproof, you can send yourself a detailed email from within the app which contains all necessary information and all technical details to make sure that you can verify the video you have taken.

    This sounds great, but I don't know you and I don't trust you!

    Good on you! We don't take it personal :-) actually, we have made sure that you do not have to trust in the app or the company behind it - All we do is facilitating the technical process for you. You do not need the airproof app to verify your airproof and its registration in the Bitcoin Blockchain. You can independently verify each and every step outside of the app.

    OK, I'll try! But what if I have more questions?
