All data you enter into Realm Works during the Early Access release will be preserved to the best of our ability. This is a Beta release, so nothing is guaranteed, but we have made sure to preserve the data of the Beta team throughout the past 18 months they've been using the product. We don't foresee any issues preserving everyone's data as we move forward, so it's 99.9% likely we'll be able to preserve data fully.
Caveat: If there's a bug we don't know about, it's possible that data could currently be getting saved improperly. If that occurs, we'll preserve everything we can, but pieces of data impacted by the bug could be compromised.
Oh, and Lenny is correct. Please post further questions about the Early Access release in the separate forum specifically for that purpose.
