External services
This plugin periodically downloads an updated anti-spam blacklist from a service operated by DigitaleZen and hosted on Google Apps Script (domain: script.google.com).
• Purpose: fetch a JSON list of abusive/disposable emails and domains used by the plugin’s firewall checks.
• When data is sent: once per day via WP-Cron (and when an admin triggers a manual update).
• What data is sent: no form submissions and no user personal data are sent. The request is server-to-server (HTTP GET) and only standard headers (e.g., User-Agent) are included.
• Storage: the downloaded JSON is stored locally within your WordPress site (e.g. under wp-content/uploads in a plugin-specific folder).

FAQ
-
Does it work without reCaptcha?

-
Do I need to configure anything?
-
No. But you can customize the weekly report recipient and enable specific shortcodes if needed.
-
Are user data sent to third parties?
-
No. All data (IP, emails, logs) remain local. The blacklist is read-only.
