Caligra looks like a genuine new computer company, not a fly-by-night operation. Selling a Linux-powered mini PC and its own operating system, the site has the kind of transparency you want before handing over payment details — a UK-registered company number, a physical London address, and a contact email. The domain was registered in 2004, which means someone has been planning this for a long time, and the site's security setup (Cloudflare CDN, valid SSL, clean Google Web Risk status) gives you no reason to worry about your data. Most legitimate hardware startups have a few rough edges, and caligra.com is no exception: it's missing some security headers and doesn't use DNSSEC, but those are minor. If you're considering buying the c100, check that the domain expiry (now under 60 days) gets renewed — a reputable company will handle that without issue. Overall, caligra.com reviews and safety checks come back clear. This is a site you can buy from with confidence.
