A: Hi - welcome to LeadCop! We're thrilled you're finding the tool smooth and non-invasive; that was exactly our goal.

Regarding domain locking: because the JS snippet is visible in your site's source code, locking the key to your specific domain is a strict security measure. It prevents bad actors from scraping your key and draining your AppSumo tier limits on their own sites.

The good news is that a single key automatically covers all subdomains for that root domain, keeping setup incredibly simple.

Let us know if you have any other questions or feature ideas for our roadmap!
