Privacy policy

Last updated 18 October 2026

This policy explains what personal data Vardex collects, why, and what rights you have. It covers this website (vardex.io) and Vardex Cloud, our platform for plant sensor data.

Who is responsible

Vardex is a brand of EFL Solutions AS, Norway, which is the controller for the personal data described here. Questions and requests: hello@vardex.io.

This website

The website has no analytics, no tracking and no cookies. It is hosted on GitHub Pages, and its fonts are loaded from Google Fonts. Like any web server, they receive your IP address and browser details when you open the page. They use this to deliver the page and to protect their services.

If you email us, we use your name, address and what you write to answer you and, if we work together, to run the project. The legal basis is our legitimate interest in replying to enquiries, or a contract with you or your employer.

Cookies

Plant and sensor data

Data from your plant (measurements, events, equipment information) belongs to our customer. We process it on the customer's behalf and on its instructions, under our agreement with the customer. If you have questions about that data, contact the company that operates the plant.

How long we keep data

Security

All connections are encrypted. Each customer's data is kept apart in the database, and Vardex staff have no access to customer data unless the customer grants time-limited support access. Changes are recorded in an audit log.

Your rights

Under the GDPR you can ask us for access to your personal data, and to correct, delete, restrict or export it. You can also object to processing based on our legitimate interest. Email hello@vardex.io and we will answer within one month. For plant data, we will forward your request to the customer it belongs to.

If you think we handle your data wrongly, you can complain to the Norwegian Data Protection Authority, Datatilsynet.
