Flinkform is a form builder that lives entirely inside the WordPress Block Editor. Forms are composed from native blocks (<code>block.json</code> v3), styled through <code>theme.json</code> design tokens, and powered by the Interactivity API — no separate admin UI, no shortcodes, no jQuery.
<h4>How it works</h4>
<ul>
<li>Block Editor native — forms are built with <code>block.json</code> and the Interactivity API, directly inside the editor</li>
<li>theme.json styling — forms inherit your theme’s typography, colours and spacing automatically</li>
<li>Modern stack — WordPress 6.5+, PHP 8.1+, no jQuery, frontend JS under 15 KB gzipped</li>
<li>Multi-step forms — split long forms into steps with a Page Break block, included in the free core</li>
<li>Conditional logic — show/hide fields based on user input, included in the free core</li>
<li>WCAG 2.1 AA — full keyboard navigation, screen-reader compatible, aria-live announcements</li>
<li>Privacy by design — no external services, no tracking cookies, no IP tracking — everything stays on your server</li>
</ul>
<h4>Features (free core)</h4>
Form building 
* 13 field types: Text, Email, Textarea, Number, Date, URL, Phone, Select, Radio, Checkbox, Toggle, Hidden, Section Heading 
* Dedicated Consent field for privacy-policy agreement 
* Multi-step forms with Page Break block, per-step validation and progress indicator (bar, dots or numbers) 
* Conditional logic — show/hide fields, skip steps, gate the submit button 
* Two-column layout with per-field full-width override
Styling 
* Automatic theme.json inheritance (colours, typography, spacing, border radius) 
* Style panel: primary colour, field style (bordered/soft/underline/minimal), label position (above/beside/floating/placeholder), submit button style (fill/outline/ghost)
Notifications 
* Admin notification email on every submission (configurable recipient, merge tags) 
* Optional confirmation email to the submitter 
* Sends through your site’s standard WordPress mail (<code>wp_mail</code>)
Spam protection 
* Always-on honeypot + signed time-based check (zero configuration) 
* Built-in proof-of-work challenge with accessible math fallback for visitors without JavaScript 
* No external service, no API keys, no tracking cookies, 100% GDPR-friendly
After submission 
* Success message or redirect to a custom thank-you URL (with open-redirect protection) 
* Optional submission ID and form ID query parameters for conversion tracking (GA4, Meta Pixel, Plausible, etc.)
Admin 
* Submissions list with search, filter by form, sort, bulk actions 
* Single-submission detail view with all field labels and values 
* Mark as read/unread 
* Per-form data retention with automatic daily purge
<h3>Privacy</h3>
Flinkform is built with privacy by default. Here is what the free core does and does not do:
What the free core stores: 
* Form submissions (the field values visitors enter) in a dedicated database table (<code>{prefix}flinkform_submissions</code>)
What the free core does NOT do: 
* It stores no IP addresses and no browser user-agent strings 
* It sets no tracking, analytics or marketing cookies. Flinkform sets exactly one strictly-necessary cookie — <code>flinkform_flash</code> (lifetime ~60 seconds, httpOnly) — and only when a form submission fails validation, to carry the error message and the visitor’s input across the page reload. Successful submissions set no cookie at all 
* It contacts no external service
Data retention: 
* By default, submissions are retained until you delete them. To comply with the storage-limitation principle (GDPR Art. 5), set a per-form retention period (Form block → Data Retention) and Flinkform deletes older submissions automatically each day 
* Individual submissions can be deleted from the admin submissions screen at any time
Data deletion: 
* All free-core data (the submissions table) is permanently removed when the plugin is uninstalled through the WordPress admin 
* Flinkform integrates with WordPress’s privacy tools (Tools > Export Personal Data / Erase Personal Data) to support data-subject access and erasure requests

unminified JavaScript/CSS that compiles into <code>build/</code>) is publicly available at:

Build instructions (Node.js 18+ and npm required): 
1. Clone the repository: <code>git clone https://github.com/dennisbuchwald/Flinkform.git</code> 
2. Install dependencies: <code>npm install</code> 
3. Build the compiled assets into <code>build/</code>: <code>npm run build</code>
The build is powered by <code>@wordpress/scripts</code> (webpack). The <code>src/</code> sources are 
excluded from the distributed plugin zip to keep it small; this repository is 
the canonical, reviewable source.

<h3>External Services</h3>
This plugin does not communicate with any external service by default. All form submissions are stored locally in your WordPress database. The following optional features may connect to a third-party service, but only when explicitly enabled and configured by the site administrator:
<h4>1. Webhook Addon (Generic HTTP POST)</h4>
What it does: Forwards form submission data to an arbitrary URL that the administrator configures inside the plugin settings (Settings → Addons → Webhook).
When data is sent: Only when (a) the Webhook addon is enabled, (b) a valid URL is provided by the administrator, and (c) a form submission is received that is mapped to the webhook.
What data is sent: The serialized form submission (form ID, submitted field values, submission ID, timestamp). The complete payload is the data the administrator configured the form to collect.
Where it is sent: The endpoint URL is entirely controlled by the administrator. The plugin does not ship with a pre-configured destination. There is no Ultimate Form vendor server involved at any point.
Service provider: N/A — the destination is user-configured. The administrator is responsible for ensuring that the receiving endpoint complies with their privacy policy and applicable law.
<h4>2. Plugin Support Form (delta-web-solution.de)</h4>
What it does: The plugin Help page contains a contact form that, when submitted by an administrator, sends an email to <code>ultimate@delta-web-solution.de</code> (the plugin vendor) using the WordPress <code>wp_mail()</code> function.
When data is sent: Only when the administrator clicks “Send” on the Help page support form.
What data is sent: The message text and reply-to email address typed by the administrator. Nothing is sent automatically.
Where it is sent: Routed via the local WordPress <code>wp_mail()</code> mailer to <code>ultimate@delta-web-solution.de</code>. No third-party API is involved.
Service provider: Delta Web Solution (the plugin author).

The free Ultimate Form plugin does not contain any license server, telemetry, analytics or “phone home” code. All feature-detection happens locally inside the plugin code. There is no upgrade or activation check that contacts a remote server.
