Understand your contacts better by knowing their interests. Scailer ethically searches for information about your contacts – profiles, social media sites, etc. – and produces a 360-degree view
I'm sorry but the "ethically searches for information [...] and produces a 360-degree view" is very sketchy at first glance, making me question the "ethically" in it.
Also, why no Linux version? I've been looking for a mail client but that is a deal-breaker for me.
We have updated the web site. Scailer tries to find an avatar and social profile links (linkedin, facebook) of a particular contact in the internet. In order to do that, Scailer takes an email address of a particular contact and sends it to the FullContact service. If additional information is found, FullContact service returns contacts avatars and social profile links to Scailer. Scailer shows avatars of contacts in the left panel. That feature improves Scailer’s user experience. “Ethically” means that Scailer uses only public information: public avatars and public social profile links, and Scailer does not share that information to 3d-parties and does not use it for advertisement.

We are working on Linux version. It will be ready in 2022.
