Bit Form gives you a flexible form-building system inside WordPress with a beginner-friendly interface and advanced form-building capabilities. External services Bit Form connects to external services only when: – You enable a specific integration (e.g., Zoho CRM, Mailchimp, Google Sheets) – You use a built-in feature that requires external processing (e.g., spam protection, icon search) Data is sent to external servers only when integrations are active (captcha/icon search are exceptions when those features are used). Enabling an integration sends form data to that service per your configuration — for example, connecting Mailchimp will send subscriber data on form submission.
