Current telemetry implementation violates GDPR

[runiq]

Hey,

I was made aware that this langserver uses telemetry with a unique identifier (log/token). I don't mind that much, but the way it's written now (always on, not mentioned in the Readme, or upon starting the langserver), it's a GDPR violation.

Which means I'm not allowed to use the langserver at work. Which is a shame because I like it :(

I understand telemetry uses a lot of its usefulness if it's opt-in by default, so I'm not suggesting to make it opt-in—but could you at least clearly, obviously mention, preferably in multiple places, that you log telemetry data?

• In the readme
• Upon installation, right at the end, so it's in the face of the user
• Upon startup (maybe even every time, until the user sets a config like i_know_god_stop_yelling_about_telemetry)

Ninja'd by #462 :) I'll close this one.
