The automatic activation of “Analytics Tracking” is extremely questionable from a data protection point of view, even if the data is anonymized, because connection data is still transmitted and this is legally personal data.
In my opinion, the better option would be to politely ask the user after the installation whether he/she would like to support the quality and further development of the client with the activation.
Personally, I support tracking, but I know users who take a “hidden” tracking very negatively.
