After entering the acf pro key on the client's site, will the key be compromised?

Question

WordPress

acf has been changing its pricing policy since 2020, in this regard, I thought about buying a developer pro.
If you ever buy this plugin, now is the best time.
But I have a question about the developer license. It is written that it can be used on an infinite number of sites and all of them will always receive updates.
To activate a license on a customer site, you must enter a license key. After entering the plugin activation key, will the key be compromised?
