I’m not familiar with them, though I did just have a quick browse of wikipedia and their privacy page. From that minimal impression I’d rate their online service as better than DeepSeek (they do claim your data is not used for training, stored in Sweden, encrypted, and deleted after 30 days) but ultimately it’s still got the same problem as other providers in that you have to just believe they’ll actually follow what they say they do. For use with your own personal info this might be an acceptable risk if the company seems reputable otherwise, on the other end of the scale for anything security classified it’d be way too much risk.
