This profile is compiled automatically from Brønnøysundsregistrene, the official business register in Norway. Riskpilot is operated by Risika A/S, which is the data controller for this page. We don't add private information — only the roles and details the register itself publishes.
Because this is public register data, it can't be erased — corrections to the underlying record are made with the register, and we pick them up once they're published. You do have the right to object to how your details are shown here, and we can de-index this profile so it no longer appears in search engines such as Google.
To make a request, email privacy@risika.com with a link to this page. We respond within 30 days. Read more in our privacy policy.
