Johku is a modern Internet technology created for digital commerce, by which a company, organisation or other party with a business ID (hereinafter ‘the merchant’) sells its products and services and, correspondingly, a private customer, company or organisation (hereinafter ‘the user’) buys the products and services sold by the merchant. Johku is developed and maintained by Aptual Commerce Oy (business ID 2735384-2, hereinafter ‘Johku’ or ‘we’).

This document explains in greater detail these principles and the rights of the registered user and merchant, which Johku complies with in personal data processing. The EU’s new General Data Protection Regulation (GDPR) is one of the most significant international legislative changes concerning data protection, the purpose of which is to increase the transparency and controllability of personal data processing from the perspective of the individual. In all aspects of our development work, we aim to comply with the stipulations in the regulation, and even to exceed them.

By using the Johku-based platform and by buying from merchants, the user accepts the conditions of this data protection principle as applying to him/herself. Similarly, by using Johku to sell products and services, the merchant accepts the conditions of the data protection principle as applying to itself.
