Can I use my license on development and/or staging environments?
Yes, ofcourse! Every license includes an infinite amount of activations for local and/or staging environments, as long as their domains match any of these patterns:
Some hosts (e.g. Kinsta and Servebolt) have their own patterns for their staging sites. If your staging site activation is taking up one of your license's activation slots, contact me and include the URL of your staging site, and I'll include the pattern to this list.
