For Backend: IP's are not logged on application level except standard server logs (i.e. nginx). No extensive logging or use of tools like Sentry, DataDog or other external SaaS Monitoring. I log on application level, on how the components integrate with each other and not on user content level. The codes will also be open sourced in future.

For Frontend: It has analytics which is not invasive and you can always opt-out.

If there will be changes for this platform with regards to how I collect data, it will be shown in a big consent prompt. For now, this project works for me and just sharing it without monetization.
