Privacy & GDPR
- Only email domains are processed for validation, not full email addresses (unless you enable features that require them).
- Data is sent to third-party services only when you enter API keys and enable those features.
- No personal data is stored on VMS Elements servers by default.
- Full GDPR compliance depends on your configuration and privacy policy.
Privacy Policy
VMS Elements Form Guard does not collect, store, or send any data from your website on its own. Every outbound network call is opt-in and only happens after you explicitly configure the corresponding API key or feature in the plugin settings.
Third-party services used by this plugin
The plugin can connect to the following third-party services. Each one is only contacted when you actively enable the matching feature and provide the required API key:
- Google Web Risk — Sends the email domain or URL hostname being validated to
https://webrisk.googleapis.com/v1/uris:search. Requires your own Google API key. Terms of Service · Privacy Policy. - VirusTotal — Sends the email domain or URL hostname being validated to
https://www.virustotal.com/api/v3/domains/. Requires your own VirusTotal API key. Terms of Service · Privacy Policy. - Google reCAPTCHA — Loaded only when you enable reCAPTCHA on a form. The visitor’s browser exchanges a verification token with
https://www.google.com/recaptcha/. Terms · Privacy Policy. - OpenAI — Sends the message body being moderated to
https://api.openai.com/v1/chat/completions. Requires your own OpenAI API key. Terms · Privacy Policy. - Anthropic — Sends the message body being moderated to
https://api.anthropic.com/v1/messages. Requires your own Anthropic API key. Terms · Privacy Policy. - Google Gemini — Sends the message body being moderated to
https://generativelanguage.googleapis.com/. Requires your own Gemini API key. Terms · Privacy Policy. - DeepSeek — Sends the message body being moderated to
https://api.deepseek.com/chat/completions. Requires your own DeepSeek API key. Terms · Privacy Policy. - Amazon Bedrock — Sends the message body being moderated to the AWS Bedrock Runtime endpoint
https://bedrock-runtime.{region}.amazonaws.com/model/{model}/invoke(the region and model are the ones you configure). Requires your own AWS access key, secret key, and model ID. Terms · Privacy Policy.
What data is sent
For each enabled service the plugin sends ONLY:
- The domain part of the submitted email or the URL hostname, for reputation checks (Web Risk, VirusTotal).
- The message text the visitor typed in a guarded textarea, for AI spam moderation (OpenAI, Anthropic, Gemini, DeepSeek, Amazon Bedrock). The chosen AI provider receives the body of the field plus a fixed system prompt.
- The reCAPTCHA token generated by the visitor’s browser, for bot-protection verification (Google reCAPTCHA).
The plugin does NOT send the full submitted form, IP addresses, user accounts, or any other personal data to these third parties.
Data stored locally
The plugin writes only to the WordPress site database. The following tables and options may be created:
*_vms_elements_form_guard_whitelist_domains,*_vms_elements_form_guard_disposable_domains— Email-domain reputation lists you manage.*_vms_elements_form_guard_logs— Validation events (domain, decision, timestamp). No personal data.*_vms_elements_form_guard_api_keys— Encrypted copies of the API keys you entered.*_vms_elements_form_guard_comment_enforcement— IP/user-ID strike counters for the optional Block User feature.vefg-google-config,vefg-virustotal-config,vefg-ai-span-config,vefg-recaptcha-config,vefg-error-messages,vefg-registration-guard— Plugin settings.
All tables and options are removed when you uninstall the plugin.
Cookies
The plugin itself does not set any cookies. Google reCAPTCHA sets its own cookies when you enable it.
GDPR
Because every outbound request requires an administrator to first enable the matching feature and provide an API key, your site only becomes a “data processor” toward these third parties after you opt in. We recommend listing each enabled service in your site’s own privacy policy.
External services
This plugin relies on the following third-party / external services. Each service is contacted ONLY after a site administrator enables the matching feature and provides the required API key or credentials. Nothing is sent by default.

FAQ
-
Does this work without API keys?
-
Yes! Basic disposable email detection and domain validation work without any API keys. Google Web Risk, VirusTotal, and AI features are optional enhancements.
-
Will it slow down my forms?
-
No. Validation is performed via AJAX before form submission. Most checks complete in under 500ms. API responses are cached to minimize latency.
-
Is it compatible with my form plugin?
-
VMS Elements Form Guard works with any HTML form. It’s tested with Contact Form 7, WPForms, Gravity Forms, Ninja Forms, Newsletter Plugin, and many more.
-
Is it GDPR compliant?
-
The plugin only processes email domains for core validation, not full email addresses. Optional features may process more data depending on your settings. No personal information is stored on VMS servers by default. You are responsible for your site’s privacy policy when using third-party APIs.
-
What data is sent to external services?
-
When configured, the plugin may send domain names (and related validation metadata) to Google Web Risk, VirusTotal, Google reCAPTCHA, and AI providers (OpenAI, Anthropic, Google Gemini, DeepSeek). See the Privacy Policy section for the full per-service breakdown.
-
How do I protect a custom form?
-
- Go to Form Guard
- Click “Add form guard mapping”
- Set Form Type to “Custom”

#my-formor.contact-form) - Configure validation options and save
-
Can I whitelist specific domains?
-
Yes. Go to VMS Elements Form Guard > Whitelist Domains and add trusted domains. Whitelisted domains bypass all validation checks.
-
Why is a legitimate email being blocked?
-
Check these in order:
1. Is the domain on the disposable list? Add it to the whitelist
2. Is VirusTotal flagging it? Adjust the detection thresholds
3. Is the HTTPS check failing? Disable the HTTPS requirement for that form -
Can I use multiple AI providers?
-
You can save API keys for multiple providers, but only one is active at a time. You can switch between providers anytime without losing your keys.
-
How many disposable domains are blocked?
-
The plugin includes over 10,000 known disposable email domains, and you can add custom domains to the blocklist.
