From a loose PDF to a contract with evidence
Six steps. None of them makes you leave the app, and every one leaves a trace in the document’s history.
Signing is the easy part. Proving it should be too.
A signature with no trail is worth nothing. Every SektorSign contract travels with its own evidence: who, when, from where, and on exactly which document.
- 01SHA-256 hash of the document
Computed when the contract closes. Change a comma in the signed PDF and the hash stops matching, immediately and visibly.
- 02IP address and device for every action
Where it was opened and signed from, along with the browser and operating system used.
- 03Server date and time
Every event is stamped with the server’s time, not with the clock on the signer’s device.
- 04Full downloadable history
Created, sent, opened, signed and closed: an evidence report that travels with the signed PDF.
- 05Encrypted in transit, servers in the EU
TLS 1.3 between the browser and the server. Documents are stored in Germany and are not shared with third parties.

To sign, the other person needs no account.

They get a link by email, open the document on their phone and sign. No sign-up, nothing to install, and nothing for you to explain.
- 01They open the link in the email
No account, no password: the link is the access. The viewer loads the whole document.
- 02They work through their fields
A counter takes them to the next required field. Nobody signs a half-filled document.
- 03They draw or type their signature
A finger on a phone screen, or their name typed. Both are recorded the same way.
- 04They accept the consent
A plain tick box states what gets recorded: declared identity, IP address, date, time and hash.
- 05They get their copy
The signed document and the evidence report, immediately and by email as well.

What everyone asks first
Exact answers. None of them promises anything the product does not do today.
What exactly is recorded when someone signs?
The identity the signer declared, their IP address, the browser and operating system they used, the server date and time of every action (send, open and signature), and the SHA-256 hash of the document at the moment it closed. All of it goes into an evidence report that travels with the signed PDF.
What is the SHA-256 hash for?
It is the fingerprint of the document. If anyone alters the signed PDF, even by a single space, the resulting hash stops matching the recorded one. It is what lets you show that the file you have is exactly the one that was signed.
Does the person signing need an account?
No. They receive a unique link by email, open the document in their browser and sign. Nothing to install, no sign-up, no payment. Only the person sending the contract needs a SektorSign account.
Can I control the order people sign in?
Not yet. The contract goes out to every signer at once and each of them can sign whenever they like, without waiting for the others. The status always shows who has signed and who has not. Sequential signing is planned, but it is not available today.
What happens if a contract expires unsigned?
It moves to Expired and its links stop accepting signatures. The record of everything that happened is kept. To try again you create a new contract with the same document.
Where are the documents stored?
On our own server in Germany, inside the European Union, and they are not shared with third parties. The connection between your browser and the server is encrypted with TLS 1.3. You can download your documents and their evidence report whenever you want.
Is an electronic signature valid for any contract?
For the great majority of agreements between businesses and individuals, yes. There are specific acts — some requiring a notary or registration — where a particular form is required, and requirements differ by country. If your case is in doubt, take advice before you send it.
Can I use my own templates?
Not yet. Saving a contract with its fields and signers ready to reuse is not built; today each contract starts by uploading its PDF. It is one of the first things we want to add.
Your next contract could be signed today.
Upload the document, add the signers and send it. The evidence takes care of itself.
