Will trial of OmniFocus 4 on my data prevent use of OmniFocus 3 if I don't upgrade

I’d like to do a trial run of OmniFocus 4. I did a quick check against some test data, but I really want to spend some time doing actual work with my real data. If I later choose not to update, will my data still be completely usable with OmniFocus3 or will some conversion of the data have been done?

No. But there are new options in perspectives that cannot be used in OF3.

Thanks for the response. I’ll give it a try then.
