Hi, Tabnine's DevRel here. I'm glad to say that we have addressed this issue: You can now easily opt-in to encrypted cloud mode through the Tabnine hub (find it under Public Model section). This option takes off most of the computing resources used to run Tabnine. That's just one out of many other improvements we've been working on lately, that are now generally available. I hope you'll give it another go! :)
