Save Historical Activity Data

Not sure if this would be a bug or a feature request.

As noted in the forum, Apple Watch has some syncing issues. My issues were so bad that I had to unpair the watch and delete my health activity data. I was disappointed that by doing so, all of my Cronometer activity data disappeared (even though the days were marked complete).

Is there a way to lock historical activity data in Cronometer so it doesn't disappear?

Thanks.... Scott
