What we process and why
Data | Purpose | Legal basis | Retention |
|---|---|---|---|
IP address, browser type, requested page, date and time (server logs) | Keeping the website secure and working, and investigating errors and abuse | Legitimate interest | 14 days |
Session data, including IP address and browser type | Protecting forms against misuse and keeping the website working during your visit | Legitimate interest | Up to 2 hours after your last activity |
Your name, email address and the content of your message, when you email us | Answering your question | Legitimate interest, or taking steps at your request before entering into an agreement | As long as needed to handle your question, and no longer than 2 years |
Your email address, language, and the time and IP address of signing up and confirming (newsletter) | Sending you the newsletter you signed up for, and being able to show that you agreed to it | Your consent | Until you unsubscribe with the link in every newsletter. Unconfirmed sign-ups are deleted after 7 days. |
The page you visit, the website you came from, your browser’s language, and your country, derived from your IP address (visit statistics) | Counting visits and seeing which pages are read, so we can improve the website. Without cookies, and without recognising you on another day or on other websites. | Legitimate interest | Your IP address and browser type are not stored: they only form an anonymous code that changes every day, and the key for that code is deleted after the day. The counts are kept for 13 months. |
The location for the weather on your watch, sent by the Momentum app: rounded to an area of about 10 km, or the place you chose. And what you type when searching for a place. | Showing the weather for your area. Our own server asks MET Norway for the forecast, so your IP address and location never reach them. | Your consent: in the app you choose whether to share your location or pick a place yourself | Not stored with your IP address, and not in the server logs. The forecast per area is kept for at most 12 hours, without any link to you. |
We do not use your data for automated decision-making or profiling, and we do not sell it.
