Shipping and logistics

When you place an order with us, we are responsible for ensuring that your package is delivered to you. We use the services of logistics providers such as UPS and K+N to handle our shipments.

For delivery purposes, it is necessary to share your name and address details with these carriers. They use this information exclusively to fulfil the delivery of your order.

If a carrier engages subcontractors, your data may also be shared with these parties, solely for the purpose of completing the delivery.

Job applications

When you apply for a position at Althen, we store your motivation letter and curriculum vitae. This information may be reviewed by the HR department and the Personnel Administration department.

If no agreement is reached, we will delete or destroy your digital and/or paper CV and motivation letter after two months, unless you have given written permission for us to retain your data for a longer period.

If an employment contract is concluded, your CV will be stored securely in a locked cabinet. Only the Personnel Administration department has access to this information.

We regularly send newsletters to customers and interested parties. For this purpose, we use the email marketing platform Zoho Campaigns. Through our newsletter, we provide information about our products and applications and share news about Althen Sensors & Controls.

When you provide us with your email address, for example when requesting a quotation, we may send you our monthly Althen Newsletter. You always have the right to object to this, and you can unsubscribe at any time by sending an email to marketing@althen.nl or by using the unsubscribe link included in the newsletter.

You can also subscribe to our newsletters via our website. After signing up for our newsletter you will receive a sign-up link to ensure that you are the person who signs up for our newsletter. After confirming via this link, your e-mail address will be added to the mailing list. If you no longer wish to receive newsletters from us, you can unsubscribe via the link in the newsletter or by emailing marketing@althen.nl.

Using Zoho Campaigns statistics, we analyse the relevance of our newsletter content. Based on these insights, we continuously improve and optimise our newsletters.

The process for reviewing recorded footage complies with applicable privacy legislation. The footage is only accessed in the event of an incident and is deleted within the legally permitted retention period.
