Agreement records for everyday life

Words fly, AlibiLock stays.

Turn a spoken agreement into a sealed digital record in seconds. The other party signs with a finger in their browser, without installing anything.

Coming soon to Google Play

A record intended as evidence of what was agreed, not a qualified electronic signature.

AlibiLock app: choosing a template

Spoken agreements are easy to deny

Money lent to a friend, a repair price agreed on the phone, a deposit paid in cash. When it comes up again months later, it is one memory against another.

AlibiLock records what was agreed, by whom and when, at the moment you agree, and seals it so it cannot be changed afterwards.

How it works

  1. AlibiLock app: writing the agreement

    Create

    Choose a template, type or dictate the terms, and sign with your finger.

  2. Send

    Share the link, or let the other party scan the QR code on your screen.

  3. The other party signing in the browser

    They sign

    The other party reads the terms in their browser and signs with a finger.

  4. Sealed agreement with its document

    Sealed

    The record is sealed. Both sides get a PDF document that anyone can check by its QR code.

Nothing to install for the other party

The person you agree with only needs the link.

  • No app, no account, no payment
  • Pages in seven languages; the agreement text stays exactly as you wrote it
  • The sealed document can be downloaded right after signing

Templates for everyday agreements

  • Loan

    Money lent between people, with the amount and the date it is due back.

  • Service / renovation

    Work, price and dates agreed with a tradesperson or a client.

  • Deposit

    A deposit or advance for a rental, a purchase or a booking.

  • General agreement

    Anything else two people agree on, in their own words.

How each record is protected

  • SHA-256 seal

    The terms, signatures and times are fingerprinted together. Any later change would no longer match the seal.

  • Chained record

    Each seal includes the one before it, so a record cannot be quietly removed or put in a different order.

  • QR verification

    Anyone holding the document can scan its QR code and check it on our verification page.

  • Encrypted storage

    Photos, signatures and documents are stored encrypted on servers in the European Union.

Frequently asked questions

Is the record valid as evidence?

AlibiLock creates digital records intended as evidence of what the parties recorded. They are not qualified electronic signatures, and how they are weighed depends on the applicable law.

Does the other party need the app?

No. They open the link or scan the QR code and sign in their browser. They need no app, account or payment.

Can a sealed record be changed or deleted?

No. A sealed record cannot be changed, and no sealed signature can be deleted. If the parties later disagree, a dispute is recorded and sealed as a separate entry.

Where is my data stored?

On servers of Hetzner Online GmbH in the European Union. The privacy policy explains what is stored and for how long.
