What constitutes Usage Data. Is it sharing the posts I view, communities I subscribe to etc?
Does paying for a premium version stop this data being collected?
No, it doesn’t. Unlike Reddit, Twitter, or Threads, Lemmy offers a variety of apps. There are so many that there is something for everyone. Even a “professional” app that finances itself with advertising or a subscription is allowed. The special thing about Lemmy is the freedom of choice.
