using the cloud designer for open source

Hi

I want to use the open source engine and the free cloud designer - i saw in another forum that the cloud designer has unlimited time access after the 30 day of the enterprise trial - my question is regarding the security after the 30 days - what will be the security for my files saved in the designer after the 30 days - will security stay the same as the enterprise trial or it will change ? is it the security mentioned in the https://www.flowable.com/product/enterprise-cloud - also is there some doc to see what are the limitations (which were included in the enterprise trail) on the designer after 30 days (e.g. do i have less components , security downgrade etc..)
