So I was interested in Lemmy, I checked Privacy policies of multiple instances; so far I cannot find any instance which doesn't collect IP address at all; many instances dont even provide any info about what data they are collection (however they are using cookies so I assume they will be logging IPs too). I found some instances that say they delete IP address logs after 12 months, these are :

1. linux.community
2. endlesstalk.org
3. lemmy.one

If anyone knows any other instance with similar or better policy for the user, kindly comment because I took quite a time to read through the "Legal" section of the instances.

Also, I find it odd that lemmy instances are storing 12 months, many firefish instances store IP addresses for 90 days
