I just wrote you an email but I'm replying here as well. If you just need to make some flowcharts they will not have a code2flow stamp in any of the pricing tiers. Maybe except free trial, but it does not watermark the output either yet. You are welcome to use the free trial until we have a paid SaaS or buy the basic self-hosted version.

The enterprise version is for companies embedding code2flow in their own products.

Many thanks!
