Liability for products

Intended use of the main products of the seller is to store private keys for crypto wallets. A full protection of the private key is physically conditioned never given. Guidance on the scope of functions and restrictions can be taken from the manufacturer’s descriptions. A responsible and professional handling of private keys in general and in relation to the goods of the seller in particular is indispensable by the customer or user. This includes in particular the creation of a sufficient number of backups of the private key including the storage at different, secure locations in suitable storage media.

A pecuniary loss resulting from the loss of a private key due to destruction, defect or loss of one of the Seller’s goods can therefore not constitute a claim for pecuniary loss.
