The word “telemetry” can mean a lot more than “detailed usage data to inform design decisions”

I’m talking extremely basic things, like, what are the most popular crashes in the app? Which did I introduce in the most recent version? Why is there an increase in end to end latency in fetching data from the server? Stuff that would fall under “bug fixes and improvements” that you would likely not notice.

The word telemetry became common when it became more than optional crash reports and update checks.

The last example sounds detailed enough. And some privacy considerations are moot when the app is a client for your server.
