How we handle your data

“No cookies, no ads and only European providers.”

When you visit the site
  • No cookiesThe site only remembers whether you chose Swedish or English, and light or dark mode. That stays in your browser and is never sent to us.
  • Bunny delivers the siteBunny sees your IP address when it sends you the page. Its logs anonymise the IP address and are kept for three days.
  • Visitor statistics on our own serverWe count visits with Umami on our own server at Hetzner in Germany. Umami uses no cookies and does not store your IP address. We see which pages are read and roughly from where, not who you are.
  • Nothing else loadsThe fonts are on our own server. No ads, no social buttons and no scripts from other companies.
When you email us
  • Email through MigaduOur email is run by Migadu in Switzerland. Switzerland has an adequacy decision from the European Commission.
  • Only to replyWe read your email to reply and to prepare a call. We do not share it or use it for marketing.
  • We delete itWe keep email while we are in touch and delete it no later than two years after the last contact.
  • Assignments and bookkeepingIf it becomes an assignment, we use the details to carry out the contract. Invoices are kept for seven years, as Swedish bookkeeping law requires.
