I. Introduction / Scope
- the following General Terms and Conditions (hereinafter referred to as "GTC") apply to all business relationships between sproof GmbH, FN 520262 t, Schlossallee 7/1, 5412 Puch bei Hallein, Austria (hereinafter referred to as "sproof"), and its respective contractual partners (hereinafter referred to as "users"). Contractual partners of sproof are exclusively entrepreneurs in the sense of § 1 of the Austrian Commercial Code (§ 1 Unternehmensgesetzbuch, UGB).
- sproof offers a platform for signing digital documents as well as a service for registering digital data in a blockchain and/or a distributed hash table/decentralized file system. The services offered by sproof allow users to sign documents or invite others to sign a document or time-stamp data and register hashes of documents.
Terms used in these GTC shall have the following meanings:
sproof sign: represents a service for creating advanced and qualified digital signatures and mapping signature workflows. Documents can be signed alone or by several persons who can be invited to provide a signature.
sproof registry: is a service for registering documents or data in the blockchain. This can be used to determine whether a document is unchanged and has been registered at a certain point in time. In sproof registry, hashes of entered data (digital fingerprint) are transferred to a public blockchain. Deletion of these hashes is technically not possible. Optionally, data can be stored publicly in a decentralized file system. Deletion of this data is not possible. The premium version uses the public Ethereum blockchain. A change of the blockchain used, if necessary due to technical or economic developments, can be carried out by sproof at any time.
Qualified electronic signature: refers to an electronic signature that is legally equivalent to a handwritten signature. Qualified electronic signatures are issued via a partner of sproof; an identification takes place via the telephone number and an official identification document of the respective user within the scope of a video identification procedure.
- the user is entitled to register with sproof free of charge by entering the relevant data. For the use of certain services and functions in the sense of these GTC a registration with sproof is required.
- sproof informs the user if the registration was successful or not. sproof can refuse the registration of a user at its own discretion without giving reasons.

- at the user's request, documents can be stored publicly in their original form in a distributed file system; deletion of these documents is subsequently no longer possible.
