Is SuperMemo using third-party online services?

Question

H.R. asked:

Is SuperMemo using an online service (perhaps a 3rd party tool) to parse articles? Wasn't this an offline process previously?

If SuperMemo is using a 3rd party tool, is that tool safe? Specifically, can the owner access statistics related to imported pages, frequency of service usage, and other forms of telemetry? If so, is there an opt-out option?

Are all of the imported articles subjected to this tool?
