In the docs here it has some incorrect information about storage and data retention.

It's mentioned that your last 10 runs will be stored indefinitely. According to this update on Slack they will only be stored for 4 months.

Also, it makes it sound the 10 runs will be stored no matter what subscription you are on. The 10 last runs thing only applies to Free plan users. Users who are on a paid plan, or have datasets that were collected while on a paid plan, the data retention period of the paid plan applies, and the data will be deleted even if the runs belong to the 10 latest runs.
