 * Intuitive admin dashboard

**Supported Languages (admin UI):**

Japanese, English, German, French, Spanish (Spain), Portuguese (Brazil), Portuguese(
Portugal), Italian, Dutch, Korean, Traditional Chinese (Taiwan), Simplified Chinese(
China), Indonesian, Vietnamese, Turkish, Polish, Swedish, Thai (18 languages).

### External Services

This plugin connects to the **Defform** service ([https://defform.com](https://defform.com)),
which uses **Supabase** as its backend infrastructure.

#### Defform Service

Defform is a form-building and AI-powered spam filtering service. This plugin requires
a Defform account to create and manage contact forms.

 * **Data sent:** Login credentials (email and password) for Defform account authentication,
   company and form identifiers for retrieving form data.
 * **When:** When the site administrator logs into the Defform service from the 
   plugin settings page, and when fetching form lists or build data from the admin
   dashboard.
 * **Service provider:** TodoONada Inc.
 * [Terms of Service](https://defform.com/terms)
 * [Privacy Policy](https://defform.com/privacy)

#### Supabase

Supabase is a cloud platform that provides the backend infrastructure (authentication,
database, and file storage) for the Defform service. All API communication between
this plugin and the Defform service is routed through Supabase.

 * **Data sent:** Authentication tokens, form metadata queries, and requests to 
   download form embed files (JavaScript) from cloud storage.
 * **When:** During login/logout, when loading form lists in the admin dashboard,
   and when downloading form build files for embedding on the frontend.
 * **Supabase anonymous key:** The plugin includes a Supabase public anonymous key(
   anon key). This is not a secret — it is a client-safe key designed for use with
   Supabase [Row Level Security (RLS)](https://supabase.com/docs/guides/database/postgres/row-level-security),
   similar to a public API key. It does not grant privileged access. It can be overridden
   in wp-config.php by defining `DEFFORM_SUPABASE_ANON_KEY` before the plugin loads.
 * **Data protection:** The Defform service enforces Supabase Row Level Security(
   RLS) policies so that only authenticated users can access their own inquiry data.
   Other users’ data is restricted at the database level. Additionally, an alerting
   mechanism is in place to immediately notify administrators if any access control
   violation occurs or if the access control system becomes inactive.
 * **Service provider:** Supabase, Inc.
