Hauhian Mylly's online store customer register

4. Legal basis and purpose of the processing of personal data / purpose of the register

The legal basis for the processing of personal data in accordance with the EU General Data Protection Regulation is the contract that arises when a customer orders products and/or services from Hauhian Mylly Oy's online store. The purpose of the register is to enable online transactions through Hauhian Mylly Oy's online store, such as the transmission of order data, invoicing data, payment confirmation data or processing data between Hauhian Mylly Oy and the customer. In addition, the register is collected to enable customer service contacts, to maintain the customer relationship and for electronic marketing communications when the customer has given his or her consent.

Hauhian Mylly Oy does not in any way store in its customer register orders placed for products of other merchants or information related to them.

The data is not used for automated decision-making. The data may be used for profiling.

Data retention period

The data will be stored for as long as the user and Hauhian Mylly Oy have a valid mutual agreement and/or consent.

Data may be kept longer to the extent necessary to fulfil obligations imposed by applicable legislation, such as, for example, accounting and consumer responsibilities, and to demonstrate that they have been properly fulfilled.

6. Regular sources of data

The data are collected through electronic forms on the Johku website. Customers enter the data personally when ordering from the Johku online store of Hauhian Mylly Oy.

7. Regular data disclosures and transfer of data outside the EU or the European Economic Area

The data is not transferred separately and remains solely with the controller. The data may be technically processed outside the EU or the European Economic Area.

8. Principles for the protection of the register

The register will be processed with due care and the data processed by the computer systems will be adequately protected. Where the data are stored on Internet servers, the physical and digital security of the hardware is adequately ensured. The controller shall ensure that stored data, as well as access rights to servers and other information critical to the security of personal data, are treated confidentially and only by employees whose job description includes this.

Data stored electronically

The register is hosted on the Johku service and processed by Aptual Commerce Oy. Only the controller and the technical maintenance staff of Aptual Commerce Ltd. have access to the complete register data.

Manual data

As a matter of principle, we avoid printing out the data in the register as manual data. If, in certain circumstances, manual data is printed from the register, it will be kept in a locked room and only the controller will have access to it.

9. Right of access and exercise of the right of access

Every person in the register has the right to check the information recorded in the register and to correct any inaccurate or incomplete information. This right is automated by the Johku system used by Hauhian Mylly Oy in the following way:

Johku communicates to the user via the My Johku service about the processing of his/her personal data in the context of the merchant's confirmation messages. The messages contain a link to the My Johku service.

In My Johku, the user can check the data stored about him/herself and, if necessary, make corrections. The service also includes functionality that allows the user to download data in a structured format for transfer from one system to another. The My Johku service can be accessed at any time at

My Johku also offers the possibility to terminate the My Johku contract and delete data from My Johku. If a user stops using My Johku and terminates his/her contract with Johku, all automated functionalities related to the management of his/her data will cease. After termination of the contract, the user must manage his/her own data (review, rectification, right to be forgotten, limitation, right to transfer from one system to another) in writing directly with Hauhian Mylly Oy. Hauhian Mylly Oy may, if necessary, ask the requester to prove his/her identity. Hauhian Mylly Oy will respond to the written request within the time limit set by the EU Data Protection Regulation (as a rule, within one month).

The use of the Oma Johku service is free of charge.

10. Other rights related to the processing of personal data

A person in the register has the right to request the erasure of personal data concerning him/her from the register ("right to be forgotten"). Data subjects also have other rights under the EU General Data Protection Regulation, such as the restriction of the processing of personal data in certain circumstances.

However, it should be noted that the data stored in the customer register of Hauhian Mylly Oy is always generated when the customer purchases products and/or services. In this case, Hauhian Mylly Oy is also bound by the obligations imposed by accounting and tax legislation to retain the data.

Requests must be sent in writing to the controller. The controller may, if necessary, ask the applicant to prove his/her identity. The controller will reply to the customer within the time limits laid down in the EU Data Protection Regulation (as a general rule, within one month).
