Today was my last day at Suomen Tilaajavastuu, where I worked on Qvarn. Tomorrow is my first day at my new job. The new job is for a new company, tentatively named QvarnLabs (registration is in process), to further develop and support Qvarn. The new company starts operation tomorrow, so you'll have to excuse me that there isn't a website yet.
Qvarn provides a secure, RESTful JSON HTTP API for storing and retrieving data, with detailed access control (and I can provide more buzzwords if necessary). If you operate in the EU, and store information about people, you might want to read up about the General Data Protection Regulation, and Qvarn may be a possible part of a solution you want to look into, once we have the website up.
