How to set the retention policy to infinite?

So, I´ve been using influxdb for a while now, but I can’t retain data for more than 30 days. But I´ve been struggling to find how to do this. Wanted to know if that kinda retention policy is a paid feature on the influx cloud and if it is which plan has that specific feature.

I searched about the feature, but I did not find anything regarding it in the plans descriptions

Hi, just started yesterday and I’m blocked on step #1 of introductory course because the new UI does not accept Flux scripts, just SQL.
While setting up my free InfluxDB account I seem to recall I noticed the 30 days retention is a limit of the subscription.
Unfortunately I can’t figure out exactly where I read so.
I expect you can overcome the issue once you move to a paid subscription
