reCAPTCHA is one of many "free" systems that are seemingly helpful and innocent, but are actually part of the #Google data-collection ecosphere.
If you are a #website / app #developer, consider using tools & APIs that do not collect user & system information.
If you must use a particular system that integrates with reCAPTCHA or similar, please provide them feedback that you would like alternatives to Google services.
Users, choose to solicit sites that value your #privacy and user data.

However, if there is no choice, avoiding the Google ecosystem likely increases privacy.
